8.1 Pump flow integrator (Art. No. 4803)

The LAMBDA VIT-FIT syringe pump and the other LAMBDA pumps are the only pumps on the market, which allow a simple and precise integration of the amount of liquid that has been delivered by the pump.

The electrical impulses, which move the pump motor, are registered and the RS-interface allows the control from a PC.

In chemical or biological processes, where the pump is controlled e.g. by a pH-stat it is often important to know, when and how much acid or base was added. This data yields important information about the process, its kinetics and time of completion, etc.

Another use of the INTEGRATOR is for the measurement of enzyme activities (e.g. amidases, esterases, lactamases, lipases, proteases and other enzymes).

The PUMP-FLOW INTEGRATOR can now be electronically implemented inside the VIT-FIT and VIT-FIT HP syringe pumps and, therefore, does not require any additional valuable laboratory bench space.

The INTEGRATOR connected to LAMBDA pumps allows new and unusual applications (e.g. gradient making, counter flow elution, liquid chromatography, electronic burette, etc.).


8.2 PNet control software for peristaltic and syringe pumps, DOSER or MASSFLOW (Art. No. 6600)

PNet is a PC control software for the remote control of LAMBDA laboratory instruments (syringe pump VIT-FITperistaltic pumps PRECIFLOW, MULTIFLOW, HIFLOW, MAXIFLOW & MEGAFLOW, powder dosing instrument DOSER & HI-DOSER and gas flow controller MASSFLOW).

The pumps are connected to the computer through a RS-232 or RS-485 interface.

Up to 6 LAMBDA laboratory instruments and 12 INTEGRATORs can be connected and controlled simultaneously.

If other functions are needed, you can make contact with us (support@lambda-instruments.com).

If possible, we will integrate the desired functions in your software system, in such a way that it conforms optimally to your specifications.
