Zinsser Analytic GmbH - TFA Dispenser

Each system has 4 component modules:

• the nozzle indexing module
• the pump module
• the control interface
• the control cabinet

The nozzle indexing module is the unit on which a plate is placed to be filled. It includes the automated mechanism to position the nozzles over the wells or priming tray. It is optionally available with an extra “nozzle shift” motion to enable filling 384 well plates with the same grouping of 8 nozzles used to fill 96 well plates.

The pump module contains a grouping of pumps with tubing and fill nozzles. Nozzles are attached to a holder which mounts onto the nozzle indexing module. For most solutions, dispense volume CV’s of 1% or below can be expected down to 5 µl doses and 3% or below down to 1µl doses

Various pump module designs are available to suit different fill pattern and volume range requirements. They are designed for quick changeover allowing for multiple uses of the same basic system. Pumps can be arranged to fill all wells with the same reagent or to put different reagents into specific wells. System speed depends on how many pumps are used.

The control interface can be your choice of:
manual keypad interface module (most commonly used),
manual PC interface (via RS232 com cable to PC serial port; requires optional software and PC),
automated remote PC interface (via RS232 com cable to PC serial port; requires optional software)

The control cabinet is a stainless steel cabinet 380mm wide by 390mm high by 210mm deep. It can be placed or mounted various ways within 2 metres (6 feet) of the nozzle indexing module. There are three signal cables and one power cable coming from this box. One signal cable is for the pump module another is for the nozzle indexing module and the third is for the control interface.
