Section 2
Introduction
2.1 VersaDoc System Capabilities
The VersaDoc Imaging System is a quantitative imaging system for capturing high
resolution digital images from single and multi-color fluorescence,
chemiluminescence, chemifluorescence and colorimetric samples. Using cooled CCD
technology in combination with a unique ultraviolet illumination mechanism and a
highly efficient optical design, the VersaDoc offers researchers the sensitivity,
uniformity, flexibility and dynamic range they require for the analysis of
electrophoretic and microplate samples, among others. With direct imaging and
automated acquisition, this system can increase laboratory throughput and eliminate
the need for chemiluminescent detection using x-ray film.
Flexible Design:
The VersaDoc Imaging system has a very flexible design. The light tight enclosure
can accommodate any of the offered camera modules. The user has the option to
upgrade to any of the four standard models. The standard VersaDoc comes with
every feature included. The VersaDoc 1000L, 3000L, 4000L and 5000L come with
light tight enclosure, camera and filter wheel. The user has the option to choose a
variety of illumination modules to fit their needs. This allows customization of the
system by selecting the type of camera and the type of illumination you need.
Additionally, all systems can be upgraded.
2.2 System Description
Figure. 2.1 The VersaDoc Imaging System.
The VersaDoc combines several key components into a unique, powerful and fully
integrated image analysis system:
User’s Manual • 2-1
(1) Cooled CCD Technology
The VersaDoc system uses cooled CCD technology for image capture and improves
image quality by reducing background noise and enhancing the signal to noise ratio.
This is particularly important for low light chemiluminescence and fluorescence
applications.
(2) Unique Trans and Epi-illumination Source
The VersaDoc system incorporates unique trans and epi-illumination modules for
both UV and white light excitation. This provides high-sensitivity imaging of a variety
of fluorescent, chemifluorescent and colorimetric samples. The broad bandwidth UV
excitation (290-365 nm) supports the detection of a broad range of fluorescent dyes
in contrast to the limited number of dyes, which may be excited using a single
wavelength visible laser.
(3) Interchangeable Lens
The
VersaDoc is supplied with two standard lenses. One zoom and one 50 mm
mono-focal.
Depending upon which VersaDoc system has been purchased, either a 20-40 mm or
the 28-80 mm zoom lens will be included. This zoom lens is ideal for most
fluorescence and colorimetric applications.
The 50 mm, f1.4 fixed lens has a high light collection efficiency and is the lens
recommended for all chemiluminescence applications.
You may purchase an optional 105 mm lens that can be used for imaging small
samples at high resolution. The VersaDoc will accommodate most Nikon f-mount
lenses with a minimum operating distance (MOD) of 0.65 m.
It is highly recommended that lenses be purchased through Bio-Rad, as some Nikon
lenses require modification before they can be inserted into the filter wheel housing.
Use of an unmodified lens may result in damage to either the instrument or lens
mount.
(4) Emission Filters
An eight-position emission filter wheel has been incorporated into the optical design
of the VersaDoc to permit multi-color image discrimination and the detection of many
different fluorescent dyes. The VersaDoc is supplied with four standard filters. Filter
#1 (520LP-Long Pass) is optimized for single color detection of ethidium bromide,
DNAStar, SYBR
Red, SYPRO
Ruby, Texas Red, Cy2, Cy3 and most fluorescein and rhodamine
derivatives. Filters #2 (530BP60) and #3 (610LP) are for the independent detection of
green (fluorescein) and red (Texas Red) fluorescence in multiple colored samples.
These filters effectively support multiplexing analysis for increased sample throughput
and more accurate molecular weight determination. Filter #4 is a clear filter that can
be used for white light applications. Filter positions (Filter #6 #7 & #8) are available to
users for the installation of application specific custom filters. Filter position #5 should
be left vacant for the optimized collection of chemiluminescent samples.
User’s Manual • 2-2
(5) Quantity One 1-D Analysis Software
The Quantity One software permits user-friendly control of the VersaDoc Imaging
System and accurate analysis of the captured image or data. Quantity One is
designed for operation in a Windows or Macintosh environment and supports fully
automated application-based image acquisition.
NOTE: Windows NT does not support USB therefore all WINDOWS NT based systems must use a
Serial Communications port.
The Quantity One package allows substantial flexibility in the presentation of captured
images and provides many tools for data analysis. These include molecular weight
determination, automated lane and band finding, accurate concentration analysis,
VNTR and differential display studies and colony counting. Please refer to the
Quantity One instruction manual for a full description of this software package.
2.3 Mechanical Description
The VersaDoc Imaging System is a modular system and it consists of the following
main hardware components. See figure 2.2.
1. The light tight enclosure, which integrates the sliding UV transillumination module,
two epi-illumination modules, chemiluminescence tray, access to the filter wheel,
lenses and all the electronics needed for controlling the lights and filterwheel.
2. The camera module, which integrates the cooled CCD camera.
3. Depending on which model of VersaDoc you have (1000, 3000, 4000 or 5000),
you will have the corresponding camera module but the light tight enclosure will
be the same.
4. VersaDoc is also available in a "LITE" versions (1000L, 3000L, 4000L or 5000L)
where no illumination sources are included. The unit is offered with a light tight
enclosure and a camera with a filter wheel. All illumination modules, lenses, and
filters are customized for your specific needs.

2.4 Overview of the Imaging Process
The acquisition and analysis of image data using VersaDoc technology is a simple
five-part process.
Step 1: Samples to be imaged are placed on the transilluminator module.
Step 2: The appropriate imaging method is selected in the VersaDoc acquisition
window of Quantity One.
Step 3: The sample is aligned using the positioning template in the Quantity One
acquisition window.
Step 4: If required, the imaging lens is zoomed and focused onto the sample to obtain
the highest quality image.
Step 5: The desired collection time for an aperture setting of the lens is selected and
the image is captured. In cases where Flat Fielding is selected, a reference image is
also acquired (see below). Once the sample image is collected and saved, this
Image can then be reviewed and analyzed using the appropriate tools bundled in the
Bio-Rad software package. Please refer to the software manual for further details.
2.5 Illumination Flat Fielding:
A uniform images are essential for quantitative analysis. The VersaDoc Imaging
System features a proprietary algorithm that allows elimination of image nonuniformities caused by lens, illumination source. Optimization of the image uniformity
is made possible via the Illumination Flat Fielding function in the image acquisition
portion of the software.
NOTE: This feature is only for imaging applications that utilize a UV or white
light transillumination source.
Illumination Flat Fielding when using the UV transilluminator:
The software takes an initial image and then prompts the user to remove the sample
and to place the VersaDoc Fluorescent Reference Plate provided with your system
on the UV Transilluminator.
Illumination Flat Fielding when using the white light conversion screen:
The software will prompt the user at the beginning of the image acquisition to place
the VersaDoc white light conversion screen on the UV transilluminator. The sample is
placed on the conversion screen; an initial image is taken. The software then
prompts the user to remove the sample from the VersaDoc white light conversion
screen and then finishes image acquisition.

3.2.9 Installing the Lens
The VersaDoc system is supplied with two standard lenses, a flexible zoom
lens and a high NA 50-mm lens with improved collection efficiency
Zoom Lens for fluorescence and colorimetric imaging
The Tamron zoom lens is recommended for use with all fluorescence and colorimetric
applications and for high intensity chemiluminescence experiments. The zoom
capabilities of this lens supports the imaging of small and large samples. The zoom lens
is not a high numerical aperture (NA) lens and should not be used for low intensity
chemiluminescence experiments.
High Numerical Aperture Lens for Chemiluminescence Imaging
The Nikon 50 mm high NA (f/1.4) lens is designed for optimized light collection
efficiency and should be used for all low intensity chemiluminescence experiments. The
lens can also be used for collecting typical fluorescence and colorimetric images. The
chemiluminescence sample tray may be used to move the sample closer to the camera.
Infrared Cutoff Filter
When performing any fluorescence experiments it is required that the 660 nm infrared
cut-off filter that is supplied with the VersaDoc is installed on the front of collecting lens.
This filter will block any infrared signal that will be generated by the UV bulbs,
substantially reducing image background and improving sensitivity. This filter is not
required for chemiluminescence experiments and should not be used when collecting
low intensity chemiluminescence signals, as it will reduce the amount of signal
collected.
Lens Use Recommendation
For optimal image acquisition, it is recommended that the zoom lens with 660 nm cut-off
filter installed is used for all fluorescence and colorimetric applications. In
chemiluminescence experiments, the 50 mm fixed lens with no cut-off filter is
recommended.
Zoom Lens Installation
To correctly install the zoom lens. Follow the procedure outlined below (Figure
3.20):
1. Remove the lens from its packaging and retain the packaging for future storage.
2. Remove the front lens cap and install the 58mm-52mm step down ring, then the
660 short pass (SP) filter onto the lens.

Operating the VersaDoc
4.1 Starting the VersaDoc System
Both the VersaDoc and the camera module must be connected to the computer prior to
using the VersaDoc system.
To turn on the VersaDoc press the power switch located on the right-hand side of the rear
panel of the instrument. The green LED on the front will illuminate indicating that the
system is ready and to confirm that power is being supplied and all the internal light
modules are functioning properly. The start up initialization process takes approximately 30
seconds. After this time has elapsed the host computer can be turned on. At this time you
can also power up the power supply or CEU if you have a VersaDoc 3000 or 5000 system.
Note: If the LED indicator fails to illuminate and the instrument is inoperative, check that all power cables
are firmly attached and that power is being supplied to the unit. If the unit still remains inoperative or the
VersaDoc acquisition window cannot be opened on the host computer, please contact the Bio-Rad
Technical Service Department for assistance.
The VersaDoc should be switched on at least 30 seconds before the host computer, to
allow for complete initialization. If the VersaDoc is not fully operational before the computer
is turned on, the system will not be recognized as an attached Serial/USB device and the
camera may not be recognized by the digitizing card thus you will not be able to
communicate with the VersaDoc from the Quantity One acquisition window.
For best imaging results it is recommended that the VersaDoc be allowed to warm-up for
10 minutes before use.

4.3 Detailed Operating Procedures
4.3.1 Opening the Acquisition Window
After starting your computer, open the Quantity One acquisition and analysis program by
double clicking on the Quantity One icon.
From the FILE menu select VERSADOC to open the instruments acquisition window. The
following window will open on the screen.
Note: If the computer cannot establish communications with the VersaDoc a message will indicate this and
give the user the option of entering a simulation mode.
Figure. 4.1. VersaDoc acquisition screen in Quantity One.
User's Manual • 4-2
4.3.2 Selecting the Application
The Quantity One program uses an application-oriented format to simplify user selection of
collection parameters. To correctly set the parameters for collection, simply click the
SELECT button in Step I (Figure 4.1) and identify the application name matching your
sample type. For detailed acquisition instructions please refer to the Quantity One software
instruction manual.
4.3.3 Placing Samples in the Imaging Chamber
The VersaDoc can accommodate a variety of sample types and sizes. The sample stage is
25 X 25 cm. This configuration supports the acquisition of smaller areas of interest within
very large samples. The imaging area is liquid sealed so wet samples may be placed
directly into the imaging chamber on the UV transilluminator platen. With wet samples you
will find it convenient to use the sample holders provided with your VersaDoc system.
These sample holders have suction cups that hold the sample in place and keep it from
sliding around on the polished glass surface.
Caution: The sample stage area is resistant to most research chemicals but may be
damaged by extended contact with strong acid solutions and organic solvents. When
imaging samples exposed to these chemicals, users should wash the sample stage with
water and wipe dry immediately after imaging.
Samples should be placed in the VersaDoc instrument following the steps outlined below:
1. Open the main door.
2. Visually check that the sample platen is clean. If not, clean using an optical cleaning
solution and a soft lint-free towel or lens cleaning tissue.
3. From the VersaDoc acquisition window select the POSITION function in Step II (Figure
4.1). The image display window will now present a real time image of the sample in the
chamber that refreshes rapidly.
4. Position your sample on the imaging platen, using the software generated alignment grid, to
ensure that it is correctly placed and in the center of the viewing area.
Note: When imaging fluorescent gel samples it is recommended that the sample be removed from the glass
or plastic plates of the gel sandwich for good image quality. The glass and plastic will fluoresce when
exposed to UV light and will contribute to background signal.
Sample/Chemi Tray
It is recommended that the Sample/Chemi tray (Figure 4.2) be used for all small
chemiluminescence samples (8 x 8 cm or less). This tray slides onto the guides on the
each epi-illumination assembly and allows the sample to be placed closer to the camera.
Large chemi samples should be imaged on the platen. To insert and remove the chemi
tray, the door to the enclosure must be fully opened.
Note: When using the VersaDoc for non-chemiluminescence applications the sample tray should be
removed from the enclosure, as it will block sample signal from reaching the CCD camera.
When using white light epi illumination the sample tray should be placed on the dark reflective platen of
the transilluminator to avoid unwanted reflections on your image.
User’s Manual 4-3
Fig. 4.2. VersaDoc chemi sample tray.
4.3.4 Lens Selection and Setup
The VersaDoc system is supplied with two standard lenses, a flexible zoom lens and a high
numerical aperture 50 mm lens with improved collection efficiency.
For optimal image acquisition, it is recommended that the zoom lens with 660 nm cut-off
filter installed be used for all fluorescence and colorimetric applications. This lens can also
be used for high intensity chemiluminescence experiments, however it is not ideal for this
type of application.
For the best chemiluminescence results, it is recommended that the 50 mm fixed lens with
no cut-off filter be used. The 50 mm high NA (f 1.4) lens is designed for optimized light
collection efficiency and will produce superior images for all low intensity
chemiluminescence experiments. The lens can also be used for collecting typical
fluorescence and colorimetric images, however the imaging area is fixed. This lens is
designed to work in combination with the chemiluminescence sample tray, placing the
sample closer to the camera for improved light collection efficiency
Infrared Cutoff Filter
When performing any fluorescence experiments it is recommended that the 660 nm infrared
cut-off filter that is supplied with the VersaDoc be installed on the front of collecting lens
(see figure 4.3). This filter will block any infrared signal that may be generated by the UV
bulbs, substantially reducing image background and improving sensitivity. This filter is not
required for chemiluminescence experiments and should not be present when collecting
low intensity chemiluminescence signals, as it will reduce the amount of signal collected.

4.3.5 Aperture Adjustment
The aperture or f-stop ring is located at the top of the lens (Figure 4.4) and controls the
amount of light that passes through the lens to be captured by the CCD camera. When the
aperture is fully open, the f-stop number will be smallest, the depth of field will be the lowest
and the most light will pass through the lens. When the aperture is fully closed, the f-stop
number will be largest, the depth of field will be highest and the least light will pass through
the lens. For low signal applications such as chemiluminescence, it is recommended that
the aperture be fully opened to the smallest f-stop value.
Note: When the aperture on the zoom lens is fully closed (largest f-stop setting of 22), the aperture ring
locks. To unlock the aperture ring push the black release button to the right of the f-stop indicator while
turning the ring to the right (counter-clockwise).
Note: The aperture ring on the 50 mm lens will not lock in the fully closed (f-stop 16) position, unless the
user activates the lock mechanism on the lower right hand side of the f-stop indicators. To lock in this
position move the button (white dot) up so that it aligns with the orange indicator. It is not recommended
that the lens be locked in this position for chemiluminescence experiments as this setting allows the least
light through the lens.
4.3.6 Zoom Adjustment
When using the zoom lens the view area of the image can be adjusted by rotating the zoom
ring (Figure 4.4). The zoom ring is located directly below the aperture ring. At maximum
zoom the indicator on the lens will be set to its highest specified focal length 40 or 80 mm
depending on which lens is being used, also the image resolution will be at its best.
The zoom setting can be adjusted and viewed in real time by selecting the POSITION
function in the VersaDoc acquisition window. The image display window will now show a
real-time image of the sample, as it will be captured. This image refreshes every second to
help you optimize your zoom settings.
Note: The 50 mm lens offers no zoom adjustment.
User’s Manual 4-5
4.3.7 Focus Adjustment
To focus the lens on the sample for sharp images you must choose the FOCUS button in
the Quantity One acquisition window. This button allows focusing on a small part of the
image. When using this mode the white epi lights turn on automatically and the shutter is
opened and closed repeatedly and the acquisition window is continuously updated to allow
you to focus your lens on the sample. The exposure time during the focus mode is adjusted
automatically to allow proper unsaturated images. If during focus mode the images still
show up saturated, then you must adjust the aperture to a lower setting to view the images
in the focus mode. If the images still show up as saturated (all white), then you may turn off
the epi lights by clicking on the button labeled "Lights On" (see figure 4.1). This will turn off
the white lights and now you may open the main door and adjust the focusing ring (See
Figure 4.5) on the lens to achieve a sharp focus on your sample.
4.3.8 Exposure Time
The exposure time refers to the period of time that the shutter will remain open and light will
pass from the sample to the CCD. As such, the longer the exposure time, the brighter the
captured image will be. For high intensity applications including colorimetric and high
intensity fluorescence experiments, an exposure time of only a few seconds is typically
required. For low intensity applications such as chemiluminescence, an exposure time of
several minutes may be required. The exposure period required to produce an optimal
image varies considerably and may need to be optimized for your particular sample. Typical
exposure conditions for different sample types have been included in Table 4.1 as a guide
to selecting a suitable exposure time. This table also indicates the preferred lens for the
sample and if any accessories are recommended.

4.3.9 Acquiring the Image
To collect the sample image, simply press the ACQUIRE button. The yellow LED on the
front panel of the VersaDoc will flash during acquisition to indicate that the image is being captured. The software will automatically set all instrument collection parameters and
prompt you to take additional steps for best results.
NOTE: You will notice that after the initial image capture, the software also acquires a dark image. This
image is taken for the same amount of time as the exposure, however, this dark image is acquired with the
camera shutter closed. This provides a very accurate way to measure and remove the dark current noise
from the image.
Once the image is captured, it will be displayed in its own window. You may save the
captured image for storage and/or future analysis.
NOTE: When an application is selected that utilizes UV transilluminator, the software will first acquire an
initial image and then prompt you to remove the sample. You must make sure that the sample platen is free
of any solution from the sample. You will then be prompted to place the VersaDoc Fluorescent Reference
plate.
When your application requires white light transillumination, the software will also prompt
you to place the VersaDoc white light conversion screen on the UV transilluminator platen.
This white light conversion screen absorbs the UV from the UV transilluminator and
converts this broadband UV into white light. See figure 4.5.
Figure 4.5 White Light Conversion Screen
In this application, the software will first take an initial image and then prompt you to
remove the sample.
NOTE: Please make sure that the surface of the VersaDoc white light conversion screen is clean after the
sample has been removed.
After the image has been acquired, its appearance can be optimized. The image may also
be analyzed in various ways using the Quantity One program. Analysis options include
object volume analysis, lane profile analysis including regression analysis and molecular
weight determination, colony counting, fingerprinting, VNTR and differential display studies.
The image and various data reports may also be printed or exported to other software
programs. Please refer to the Quantity One software manual for detailed instructions.
Note: Please refer to the Quantity One software manual for information concerning additional features
available in the acquisition window for VersaDoc.

2. Open the main door and slide out the transilluminator assembly.
3. Clean the top platen using optical cleaning solution and optical tissue.
4. Once the platen is clean, push the transilluminator back into the enclosure.
User's Manual • 5-1
5.1.3 Cleaning the Lens
To optimize image quality it is recommended that any lens used with the VersaDoc be
cleaned before it is installed in the system. Both sides of the lens should be cleaned using an
optical cleaning solution and optical tissue. Avoid touching the glass surfaces of the lens
when installing it into the instrument, as fingerprints will effect image quality.
5.1.4 Cleaning the Emission Filters
To optimize image quality it is recommended that the emission filters installed in the
VersaDoc system are periodically cleaned. Both sides of each emission filter should be
cleaned using an optical cleaning solution and optical tissue. Avoid touching the glass
surfaces of the filter when installing it into the instrument, as fingerprint will effect image
quality.
5.2 Replacing Lamps in Illumination Sources
The life of the broad wavelength UV lamp is approximately 500 to 1000 hours, depending
upon use. As the lamp ages, the required integration time will increase because the intensity
of the UV emission will diminish. If the integration time for image acquisition has increased
more than three-fold, it is recommended that the lamps be replaced. The life of the white
light lamp is approximately 1000 hours.
NOTE: THE LAMPS SHOULD BE REPLACED IN PAIRS FROM ALL ILLUMINATION MODULES.
5.2.1 Replacing the Lamps in the Transilluminator Module
To access the lamps in the transilluminator follow the procedure outlined below.
Caution: Do not touch the glass parts of the lamp or lamp housing. Fingerprints on the
lamp may result in non-uniform illumination. The use of power-free latex gloves is highly
recommended.
Tools required: You will need a #2 Phillips screwdriver and 5/16 size socket wrench to
change the lamps in the transilluminator.
To change the lamp, follow the procedure outlined below (Figure 5.1):
1. Turn off the power to the system.
2. Open the main door to access the UV transilluminator cable.
3. Disconnect the UV transilluminator cable from the ballast assembly.
4. Slide the UV transilluminator module on the slides out completely.
5. There are two release levers on each rail that are made out of black plastic. Pull the
transilluminator module out while pressing down on the lever on the right side and lifting
up the lever on the left. This will allow you to completely disengage the slide rails from
User's Manual • 5-2
the guides rails located in the enclosure and the entire transilluminator module will
become free from the enclosure.
Release lever for slides Transilluminator Transilluminator without the cover
Figure 5.1
6. Using the Phillips screwdriver, remove the cover assembly from the transilluminator by
removing four screws. There are two screws on each side of the cover.
7. Using the 5/16" socket wrench, remove the four hex standoffs that hold the baffles on the
lamps of the transilluminator and then gently lift off the baffles exposing the
transilluminator lamps.
Note: Be careful and do not bend the baffles because bending the baffles could lead to deterioration of
uniformity of your UV transilluminator.
8. Remove lamps by holding the metal part of the lamps with the tip of your fingers and
turning them in a rotating movement and by pulling them out of the socket. (See Fig 5.2)
Remove hex standoffs (X4) Remove the baffle exposing the lamp Hold at the metal ends of the
lamps and turn to remove
Figure 5.2
9. Install the replacement lamp by inserting its ends in the sockets and rotating until it clicks
into place.
10. Now reinstall the baffles on the lamps by making sure that they are seated correctly.
11. Reinstall the cover on the transilluminator module. Replace the screws.
12. Carefully reinstall the transilluminator assembly back onto the slides by carefully lining up
the slides into the guides and then gently push in all the way.
NOTE: There is no need to push down or up on the levers, they are only used to remove the
transilluminator assembly.
User's Manual • 5-3
13. Next carefully connect the UV transilluminator cable back to the ballast assembly. Turn
the power ON to the system.
14. Make sure that the door is closed.
15. Try an application that requires use of UV transilluminator to make sure that the new
lamps are fully operational.
5.2.2 Replacing lamps in the Epi-illumination module
Tools required: You will need a size 3/32" hex allenkey to change the lamps in the epi
illumination module
The VersaDoc has two epi-illumination modules each contain single white illumination source
and broad bandwidth UV sources. It is recommended that lamps in both the right and left
epi-assemblies must be replaced at the same time.
To change an epi-lamp, follow the procedure outlined below (Figure 5.3):
NOTE: The procedure to remove and replace the lamp in the UV or white light epi modules is the same. The
procedure outlined below applies to both.
1. Turn off the VersaDoc and disconnect all power, removing the power cable.
2. Open the door to the sample compartment.
3. Find the threaded mounting screw that secures the epi modules to the wall of the
enclosure and loosen it to free up the epi module from the wall.
4. Disconnect the epi module cables from the ballast assembly and remove the epi module
completely from the unit and set it on a clean bench.
5. Using a hex 3/32" key remove the three screws that secure the front end plate on the epi
modules and slide out the end piece and filter glass and set aside for future use. See
Figure 5.3.

6. This exposes the lamps in the epi module for you to replace. To replace the white light
lamp or UV lamp simply grab the two metal ends of the old lamp and carefully rotate to
release it from the sockets. See Figure 5.4
Remove lamp by grabbing the two metal ends and turning the lamp to release from its socket
Figure 5.4
16. Install the replacement white light lamp by placing its ends in the sockets and rotating
until it clicks into place. Be careful not to touch any glass surfaces of the lamp or the filter
glass. Use of latex gloves is highly recommended.
17. Carefully rotate the lamp to make sure it is seated properly.
18. Now reinstall the filter glass, end piece and the end plate. Secure the end plate properly
using the 3 cap head screws and the 3/32” hex Allenkey.
19. Reinstall the epi module in its place and reconnect epi cables to the ballast assembly to
appropriate connectors.
20. Now power up the system and try running the application that use the epi source in which
the lamps were installed to make sure that the lamps are operating normally.
NOTE: THE UV INTERLOCK ON THE MAIN DOOR WILL NOT ALLOW UV EPI TO TURN ON.
ACQUIRE AN IMAGE OF A WHITE PIECE OF PAPER TO ENSURE THAT THE EPI UV LAMPS
THAT YOU JUST INSTALLED ARE WORKING PROPERLY. IF NO IMAGE COMES UP YOU MAY
HAVE A POORLY SEATED LAMP IN THE SOCKET.
To order replacement lamps contact your Bio-Rad Laboratories representative for parts.
5.3 Lens and Filter Storage
Always store unused lenses and filters in their original box and in a low humidity environment
with a stable ambient temperature that does not exceed 30 °C.
Lenses should be wrapped in optical tissue before being placed in their storage box. If your
laboratory is a high humidity environment it is recommended that all emission filters are
stored in a sealed container with desiccant.
