1Safety precautions and application
•Observe operating instructions!
•The device is only designed for use in the research lab!
•The FemtoJet express is a lab device. It may only be operated by appropriately qualified lab
personnel.
•Only use the device for microinjection under observance of all relevant legal regulations!
•Before plugging in the device, please compare your voltage requirements with the specifications on the identification plate!
•The unit may not be connected to a socket that is not grounded! Use the appropriate mains cable.
•Electrical connections may be effected only when the device is switched off!
•The unit may be opened only by authorized service personnel! Potentially lethal voltage inside the unit.
•Do not use the unit if damaged. This applies in particular when the mains cable is damaged.
•The connection of the pressure tube to the high-pressure flasks, compressors or building pressure systems is not part of these operating instructions! The connection may only be carried out by trained personnel or tradesmen, taking into account the local regulations.
•The device may only be operated with dry, non-oiled, pressurized air or purified nitrogen gas with 4000 hPa to a maximum of 8000 hPa (4 bar – 8 bar, 58 PSI – 116 PSI)!
Other gases are not permitted!
•Loud hissing may occur when coupling or uncoupling the pressure tube! Don't be alarmed! When coupling, hold the ears at an adequate distance from the coupling!
•The pressure tube of the external pressure supply is not permanently UV light resistant. When using, for example, under a sterile bench with UV sterilization, this should be taken into account, and the pressure tube should, where necessary, be removed prior to UV sterilization.
•This pressure tube may not be bent. The smallest bending radius is 50 mm.
•Hold the pressure tube tightly when uncoupling! The brief pressure surge when uncoupling can cause the pressure tube to fly off! Following the uncoupling, the pressure tube remains under pressure when the pressure is not released using the Standby function!
•If the unit is not used in accordance with purpose for which it is intended, its protective function may be impaired.
•Caution!
Take care when mounting glass capillaries or tools!
Mounting must always take place without the use of pressure!
Capillaries which have been mounted incorrectly may break loose under pressure. Never point mounted capillaries at persons.
•Caution!
Take care when using glass capillaries! During mounting or when placed upon a hard surface, the glass capillaries may break and glass splinters may cause injury. It is therefore essential to wear eye protection!

2 Device description
The FemtoJet® express enables minute quantities of liquid to be injected into cells. The relevant parameters (injection pressure pi and injection time ti) are set using the variable regulators. The key or connected hand or foot control or the INJECT key of the connected
micromanipulator are used to trigger these two parameters. If no injections are being performed, compensation pressure pc is applied permanently.
The connection of an external pressure supply enables faster injections, even with higher pressure.

The display shows the following:
1st line:

counter n for number of injections performed
2nd line (bold):
The most-recently set parameter or relevant parameter
Middle line:
In the device, adjacent maximum system pressure ps.
Bottom lines:
Parameters which affect injection
Compensation pressure pc which is applied permanently in the normal mode is displayed as an actual measured value.
The arrangement of the three parameters shown, pi, ti, pc, corresponds to the arrangement of the variable regulators.
3.1.1 Setting the injection parameters
The injection parameters have to be adapted to the injection capillaries used and the cell type and liquid which are to be injected.
The following injection parameters can be set using the variable regulators:
Injection pressure |
pi |
0; 5 – 6,000 hPa |
(0.00; 0.07 – 87.0 psi) |
Injection time |
ti |
0.1 – 99.9 s |
|
Compensation pressure |
pc |
0; 5 – 6,000 hPa |
(0,00; 0.07 – 87.0 psi) |
The settings are in increments of 1 hPa/0.1 s. The display can show hPa or psi, as required. The setting and internal pressure conversion are always performed in hPa. Rounding for the display in psi can result in increments of 0.01 to 0.02 psi.
The display of pressure in psi varies according to the size of the value (e.g.: 9.99 may also appear in the display as 10.0).
Note:
An adjustment of pi or pc above the internally adjacent system pressure ps doesn't make sense. The values for pi, pc should lie at least 500 hPa (7.2 PSI) below the system pressure in order to ensure secure valve regulation.
Slight deviations between the nominal value (specified value) and displayed compensation pressure pc (actual value) may occur for technical reasons. The relevant value is the actual value measured.

3.1.2 Variable regulators
The variable regulators are set so that when they are turned slowly, the values are changed by 1 hPa / 0.1 second per notch (0.01 – 0.02 psi).
If the regulators are turned faster, the values are altered in larger increments.
3.1.3 Keypad
Inject
Performs automatic or manual injection. Automatic injection is controlled via the injection time ti, and the injection pressure pi is used. In the second line, injection time ti is counted down from the nominal value.

Manual injection is performed for as long as the 
key is held down. Injection pressure pi is used. In the second line, injection time ti is counted upwards from 0.0.
If the FemtoJet® express is connected to the Eppendorf Micromanipulator InjectMan® NI 2, 5171 or Inject Man® the injection movement of the micromanipulator is also started via the 
key. Both units then combine as a system to perform semi-automatic microinjection.
Alternatively, the INJECT key of the connected micromanipulator or the hand / foot control can be used.
If synchronization is set to "limit" (SYNC = LIMIT) in the INJECT function of the micromanipulator, semi-automatic injection can only be triggered via the micromanipulator.

Clean
The maximum available pressure for cleaning is applied at the tube outlet for as long as the key is held down. Once the key is released, the pressure drops to compensation pressure pc again. The pressure curve is shown in the form of a bar.
Auto / Manu
To switch between manual and automatic, time-controlled injection.
In the case of manual injection, time is counted upwards from 0.0 seconds. The parameter ti is not displayed in the bottom two lines in order to emphasize that the time cannot be set via the variable regulators in this case.
Count
To reset to zero the counter for injections which have been actuated.
Menu
To switch the device to menu control; selected functions may be executed.
In the first line, FUNC indicates that the device is in the function menu and shows which function number is active.
The second line contains the function description (e.g. "Select pressure unit").
