LAMBDA VIT-FIT and VIT-FIT HP high-pressure and high-speed laboratory pumps are polyvalent syringe pumps / infusion pumps offering an excellent price to performance ratio.

The syringe pump features highly robust mechanics, which result in high forces and very precise flow rates.

The flow rate range of the syringe pump ranges from 0.4 nl/min (5 μl syringe) to 6.6 l/h (150 ml syringe).

VIT-FIT laboratory syringe pump can be programmed for infusion only, withdrawal only, infusion & withdrawal and withdrawal/infusion modes. The program can be repeated in 1 to 99 cycles or endlessly.

Automatic switching off of the syringe pump, when the syringe is empty or during refill.

Unique easy sterility construction of the autoclavable laboratory fermentor and bench-top bioreactor LAMBDA MINIFOR makes the sterility maintenance a lot easier.

Elimination of critical points makes the keeping of bioreactor sterility easy. A strong silicone membrane isolates completely the vessel from the outer environment. The sterility is thus equivalent to magnetic coupling, but is considerably less complex and much less expensive.

All o-rings have been replaced by large silicone stoppers with multipoint seals. They are permanent and need not be replaced frequently as is the case with o-rings, which become flat after sterilization.

Innovatively designed bioreactor for cell culture

Two HIFLOW peristaltic pumps are controlled by PNet PC control software to generate density gradients in automated purification of isolated human islets.

PNet software controlled peristaltic pumps need instructions for dosing high and low density solutions at specific time points. This precise dosing ensures consistent gradient production.

Pump-Flow INTEGRATOR replaces OD (Optical Density) measurement for the assessment of cell growth and biomass production. Determination of metabolic activity (cell growth rate and biomass) in fermentations and cell cultures done by visualization of the amount of liquid/gas transferred as a function of time. L'INTEGRATOR détermine la quantité de liquide délivrée par les pompes et remplace la mesure de la DO (densité optique) pour le détermination de la croissance cellulaire et la production de biomasse. Détermination de l'activité métabolique (vitesse de croissance cellulaire et biomasse) dans les fermentations et cultures de cellules par la visualisation de la quantité de liquide ou gaz ajoutée en fonctions du temps
