Do you sell/ship LAMBDA VIT-FIT syringe pumps to the USA?

Yes, we do supply our syringe pumps directly with door-to-door delivery option by the parcel services to the USA.

What is the difference between VIT-FIT and VIT-FIT HP? 

The pushing force of VIT-FIT syringe pump is 300N (reducible by a switch to 80 N) and for VIT-FIT HP is 600N (reducible by a switch to 160 N). 

Why are syringe pumps with a more robust design advantageous than a plastic made?

The metallic construction and highest quality internal screws offer maximum mechanical load capacity. The robust construction offers efficiency and mechanical yield/force of the system.This is crucial for a pulsation-free operation. Also, highly viscous liquids can be handled well with a robust design than a plastic made. 

Can we control the syringe pumps with software?

Yes, VIT-FIT syringe pumps can be PC controlled through PNet software. 

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

Do you supply syringes with the Syringe Pump? 

We do not supply syringes with pumps.  Based on application, syringes can be procured locally the user itself.  

What is the smallest and largest volume syringe that I can use with your syringe pump? 

The new syringe fixing system of LAMBDA VIT-FIT & VIT-FIT HP syringe pumps allows the use of almost any syringe. Syringes made of plastic, glass or metal from 5 μl to ~150 ml syringes. 

Is it possible to have smaller than 1 minute automatic injections?

Yes, it is possible to change the injection time. In Chapter “PROGRAMMING OF THE SYRINGE PUMP “ of the LAMBDA VIT-FIT manual, you will find step by step, how to change the time resolution from 1 minute to 0.6 minutes.

Do you offer dual channel syringe pumps?

We offer the single channel laboratory syringe pump which offers better precision. Multi-syringe accessories considerably degrade the precision of delivery and produce flow fluctuations, also in immediate flow rate. This is inevitable, because mechanical resistances in each syringe vary from position to position. The relative force effects adapt to these resistances and, thus, produce speed variations.

We are looking for the syringe pump, which is suitable for slow steady supply of suspensions. Can you offer your VIT-FIT syringe pump?

According to the syringe and speed settings, the flow rates range can be possible from 0.4 nL/min. 

Can we perform electrospinning application with VIT-FIT syringe pump? 

Yes, electrospinning and electrospraying applications can be performed well with the LAMBDA VIT-FIT syringe pump. A short selection of references for these application is available at https://www.syringepump.info/publications/nanotechnology-applications/#electrospinning-electrospraying 

Is it possible to implement a pH regulator with a VIT-FIT syringe pump to pump acid or base? 

Yes, it is possible to implement a pH regulator using a VIT-FIT syringe pump to pump acid or base, a Mettler transmitter, and a pH probe. Regulation available can be ON/OFF or 0-10 V. Please contact us for more details. 

We are interested in some particular features of the syringe pump: Is it possible to achieve a maximum flow-rate: 0,7 ml/sec? 

We would need to know which syringe (diameter of the syringe) will you be using with the VIT –FIT. As soon as we know the diameter of your syringe, we can calculate the pressure and the flow rate range.
