Introduction

The UV1 and UV2 PCR Hoods create an ideal environment for preparing PCR and other samples by reducing the chance of contamination. The built-in high intensity shortwave (254nm) UV provides a source for inactivation of DNA between experiments. Additional contamination control is provided by the specially-coated stainless steel and aluminum design that maintains antimicrobial efficacy. The surface resists growth of destructive bacteria, molds and fungi. The Makrolon assembly blocks UV below 400nm.
In addition to the UV1/UV2 PCR Hood features, HEPA/UV3 PCR Hoods provide additional protection by blowing filtered air, treated by the HEPA/UV system, into the PCR chamber.
The UV/Air Circulator, included as standard on UV2 and HEPA/UV3 PCR Hoods and optional on the UV1 PCR W orkstation (95-0367-xx only), eliminates amplicons of DNA or genomic DNA from a previously-dispensed experiment. For ordering information, refer to the “Maintenance and Replacement Parts/Accessories” section.

Safety Information

The PCR Hoods are designed with functionality, reliability and safety in mind. The Hoods provide shortwave (254nm) UV which is a powerful source of UV radiation that will cause damage to unprotected eyes and skin. Before operating, ensure that all personnel are properly protected and that the instructi ons for the use of this equipment are followed. A safety shut-off switch automatically turns off the UV light when the door is open, protecting users from UV exposure. In addition, the Makrolon panels are specially formulated to block UV wavelengths below 400nm.
Disconnect the power supply before assembling or servicing the PCR Hoods.

Operating the PCR Hood

The PCR Hoods feature:
• Three-stage HEPA filtration system with pre filter, carbon filter and HEPA filter (UV3 models only)
• Overhead UV for decontamination of the chamber or PCR equipment
• UV safety switch and keylock for preventing exposure to UV
• Antimicrobial coated stainless steel and aluminum for reducing bacterial growth
• Easy-access door
• Overhead white light
• Shelves for placement of tools
• Power outlets built into the chamber interior
• Built-in UV/Air Circulator (standard on UV2 and UV3 models; optional for UV1 PCR Workstation)

Use of PCR Equipment in the Chamber

Shelves are provided for placement of small tools for decontamination. The Shelves slide into the Bracket on back of the unit.
Power outlets built into the chamber allow for use of shakers, rockers and other equipment for PCR experiments. Equipment can be decontaminated between uses. To operate equipment within the chamber, plug the equipment into the power plug. Specific power plugs are installed as shown in the illustrations below.

NOTE: W hen operating equipment plugged into the outlets, the combined amperage total is not to exceed 8 amps.

Operating the Overhead UV and Fluorescent White Lights

UV Keylock
The UV PCR Hoods provide an automated process for eliminating contamination by utilizing the germicidal properties of shortwave 254nm ultraviolet light. The UV light is typically operated when no samples are inside the chamber. The chamber is decontaminated, eliminating viable fungi, bacteria, and yeast.
An optional UV/Air Circulator can be mounted into the UV1 PCR Workstation chamber for elimination of amplicons of DNA or genomic DNA from a previously dispen sed experiment.

To use the UV decontamination function, turn the UV Keylock ON, then press the UV Timer to operate the germicidal lamp housed within the chamber. The Timer may take a few seconds to initialize once the Timer has power. The Timer will only operate when the door is shut and the magnetic safety switch on the door is engaged.
The default timer setting is 30 minutes, adjustable at 5 minute increments from 5 to 60 minutes, then at 15 minute increments up to 12 hours. To adjust the timer settings:
1. Turn the system on and wait until the timer reads “OFF”.
2. Locate the Timer Calibration Button in the small hole to the left of the timer. Use a small paper clip to press the button for one second.
3. Press the main timer button to adjust the timer settings. Each press will increase the amount of time by 5 minutes (eg 35:00, 40:00, etc.) until one hour is reached. After one hour is reached, the time will be adjuste d in 15-minute increments and will read without a colon. For ex ampl e , one hour will read “1 00,” one hour and 15 minutes will read “1 15” and so forth.
4. Once the desired time setting is reached, do not press any additional buttons. The timer will then cycle through the remainder of its settings. When the timer reads “OFF” for 5 seconds without blinking, the timer is ready to use with the new time setting.
Turn the key to the Off position after UV irradiation to prevent exposure of samples to the UV

NOTE: A safety switch sensor is built into the bottom of the door. When the door is opened, the ultraviolet lights will automatically shut off.
WARNING: Exposure to UV light is harmful.
PCR Workstations and Cabinets Page 13
Decontaminated UV airflow into and out
The Makrolon® door is UV blocking and will not allow UV radiation to pass through the door. The germicidal tubes will shut off if the door is opened. The PCR Workstation contains a powerful source of UV radiation that will cause damage to unprotected eyes and skin. Before operating any unit, be sure all personnel in the area are properly protected. Even though the unit shuts the UV off when the door is open, UV Blocking Eyewear should be worn as well. UVP has a complete line of UV Blocking Eyewear, including Spectacles, Goggles and Faceshield, designed for this purpose.
Extended periods of UV exposure can be used to disinfect the interior chamber by the destruction of organisms. Refer to the Maintenance section for information on measuring the intensity of the UV tubes with a UV meter.
NOTE: Do not attempt to perform PCR procedures with the germicidal lamp on. The germicidal lamp is used to decontaminate the internal chamber in between experiments.
Overhead White Light
The overhead white light can remain lit at any time throughout experiment procedures or the decontamination process. The fluorescent white light provides a bright light within the PCR Hood. To use the white light, press the ON button located on the top panel.

Operating the UV/Air Circulator

The UV/Air Circulator is built into the UV2 and HEPA/UV3 PCR Hoods.
To operate the Circulator, press the UV/Air Circulator switch to the ON position. The Circulator will pull air from inside the chamber through the Circulator, decontaminating the air with shortwave UV and blowing the air back into the chamber.
NOTE: Do not place equipment in front of the air vents, as this will block air flow.
An optional UV/Air Circulator module can be mounted into the top of the UV1 PCR Workstation (95-00367-XX only) for elimination of amplicons of DNA or genomic DNA from a previously dispensed
experiment. The power switch, outlet, and mounting brackets for the Circulator are pre-installed at the factory if users purchase the Circulator at a later time.

Operating the HEPA/UV System (HEPA/UV3 Model s Only)

Push the HEPA/UV power switch ON to operate the HEPA/UV filter system. The airflow fan setting can be adjusted from Low to High, circulating anywhere from 22 to 50 feet per minute (FPM) of air. The filte r system consists of:
• Pre-Filter to preserve the life of other filters by capturing large dust particles
• Carbon Filter to remove ozone, gases, odor
• HEPA Filter to provide a barrier (99.99%) against dust, bacteria and mold down to 0.3 micron
particles (NOTE: The HEPA filter does not prevent particulates from entering the workstation when the Makrolon

Care and Cleaning

The PCR Hoods are built to provide trouble-free operation.
NOTE: The door and side panels are made of Makrolon® and are subject to scuffing and scratches if improperly cleaned.
NOTE: Crazing is a normal process for Makrolon® panels exposed to UV light. Crazing will occur over a period of time. Reduce crazing by keeping UV exposure to a minimum. Crazing may occur within the warranty period and is regarded as normal wear which is not covered by the warranty. If crazing of the Makrolon part numbers.
The stainless steel and aluminum surfaces are manufactured with an antimicrobial coating to reduce bacterial growth. Care in cleaning and use of the equipment is recommended to reduce wear of the coating. To clean the unit:
• Wipe excess water from inside the unit and outside the unit with an absorbent soft cloth or sponge.
• Use mild soap and a damp, soft cloth or damp sponge to clean the exterior of the unit.
• Use a mild detergent on the interior surfaces.
• Warning: Unplug the unit before cleaning around the UV tube contacts and internal plug
outlets.
• Clean the Makrolon® panels with a mild detergent; never use organic-based compounds or cleaners containing alcohol or ammonia.
• Surface decontaminants such as RNase AWAY laboratory surfaces) and DNA AWAY™ (used to remove DNase and DNA contamination) are safe to use on PCR Hood panels.
• For general cleaning of the Makrolon is available from local plastic supply distributors.

Slide the HEPA filter out and replace filter. Close the door and tighten the knobs (turn clockwise). Insert the carbon filter. Tighten the carbon filter thumbscrews if loose. Close filter door. Retighten the knobs (2) on the workstation ceiling.

Replacing UV Tube in the Filter System (HEPA/UV3 Models Only)

Follow steps 1 and 2 under “Replacing the Filters” and remove the carbon filter as described in step 4 above. Step 5 shows location of the UV tube.
The tube has two prongs on each end. Twist the tube 90° then remove the tube from the sockets. To install a new tube, carefully hold the tube on each end and insert the tube into the socket. Twist the tube 90° until the tube locks into place.

Replace the carbon filter and retighten the knobs (2) on the ceiling of the PCR Hood.

Measuring the UV Tube Intensity

As the ultraviolet tubes age, the intensity and germicidal destruction rate decreases. It is important to monitor the efficiency of the tubes to ensure that the germicidal requirements are met. The germicidal destruction rate is a function of the UV intensity at a wavelength of 254nm and the exposure time. The lower the tube intensity, the longer the lamps must be on to accomplish the same objective.
The UVX Radiometer with a 254nm sensor will allow the user to measure the 254nm emission from the tubes. When it is time to measure the UV intensity inside the PCR Hood (recommended weekly or as needed), the sensor can be placed on the floor of the Hood. Close the Hood and turn on the UV tubes. Wait 3 minutes to record the measurement on the UV meter. It is recommended that the user record an initial value upon receipt and assembly of the PCR unit for later comparison purposes.
The germicidal destruction rate calculation:
Microwatt seconds/cm2 = microwatts/cm2 x seconds of exposure
For ordering information on the UVX Radiometer, J-225 meter and sensors, refer to the
Replacement Parts and Accessories section in this manu al. Bacterial Destruction Chart: The bacterial destruction chart below indicates the amount of shortwave
(254nm) UV energy required for the complete destr uct ion of v arious orga nis ms .
