Syringe pump

Syringe pump

High precision and excellent price/performance ratio.

Polyvalent programmable syringe pump - LAMBDA VIT-FIT

These days there are so many different types of syringes and so many different volumes used…

Some users need a standard syringe from a certain producer; others use only glass, metal or plastic syringes. Volumes start from a few microlitres to over 150 millilitres.

 Is it possible to satisfy everybody with just a single syringe pump?

With our new VIT-FIT syringe pump, we have tried to solve just this problem.

Our new syringe fixing system allows almost any syringe to be used, from micro syringes to large volume syringes, without the use of an adapter. The syringe is tightly held in both directions – infusion and filling.

In addition, the handling of the syringes is very easy.

 

Construction advantages and properties of the VIT-FIT (HP) syringe pumps

Construction advantages of the VIT-FIT and VIT-FIT HP laboratory syringe pumps

Precision mechanics for pulse-free operation

To move the pusher of the VIT-FIT syringe pumps and the VIT-FIT HP high-pressure syringe pumps, we have selected a Swiss made motor which uses new technology to ensure very high torque and ten times longer lifetime.

For the transformation of the rotation into a linear movement required for pushing the syringe plunger, we have introduced the Swiss made ball screws with highest mechanical load capacity. This is an expensive component in our instrument, but it offers decisive advantages to the user in terms of efficiency and mechanical yield/force of the system. This is crucial for a pulsation-free operation.

LAMBDA VIT-FIT and VIT-FIT high pressure lab syringe pumps are suitable for high-pressure, high-speed & counter pressure applications and handling of liquids with higher viscosity in the laboratory.

 

Metal chassis and protection

The precise mechanics is protected in the instrument casing and the pusher arm does not reach out from one side (as it is usual with existing syringe pumps), but is integrated into the rear of the instrument.

The casing and the main body of the syringe pump are made of metal with solvent resistant protection.

 

Programming flow profile (infusion and filling)

The microprocessor electronics allow control of the activity of the syringe pump in an easy but effective way. The movement of the new brushless neodymium magnet motor is constantly under the control of the microprocessor, which corrects immediately any deviation from the preset speed.

Up to 99 program steps can be memorized by the processor. The syringe pump can be programmed in both directions - delivery (infusion) and filling, locally on the syringe pump control display.

The program can be repeated in 1 to 99 cycles or endlessly.

  • Constant flow rate: In this standard application of the syringe pump – the flow rate will be kept constant during the pre-selected time period
  • Profile: Permits varying flow rates to be pre-programmed (including exponentially increasing flow rate as used for e.g. in feeding cultures during fermentation, etc.)
  • Increment: Stepwise increase of the flow rate over time (to make gradients)
  • Decrement: Stepwise decrease of the flow rate
  • Pause: Stops the syringe pump for a specified time before going on to the next step
  • Timer: By programming a required time interval with zero flow rate as the first step before the program the syringe pump can be automatically switched on or off
  • Stop: Stops the syringe pump after the program has finished.


Safe switching power supply

As the mechanical losses are so small, we can use a miniature plug-integrated switching power supply using line voltages (from 95 to 240 V AC, 50/60 Hz).

During field application the syringe pump can be powered by a 12 V accumulator or a 12 V battery.

Automatic switch OFF

The motor of the syringe pump will be switched off automatically when the syringe is empty or has been refilled.

Remote control (analog and digital)

Several remote control possibilities of the syringe pump are available:

  • Simple ON/OFF (with a 3 to 12 V DC signal or higher with resistor)
  • Progressive speed control over the whole range signal 0 to 10 V DC, (0 to 20 or 4 to 20 mA option)
  • RS-485 or RS-232 interface (option) for communication with a PC or similar device

Speed selection/syringe calibration

To be able to fit the many types of syringes used, the speed selection is made using speed numbers corresponding to the velocity of the rotation of the motor.

The selected syringe has to be calibrated. This means that the motor speed setting (000 to 999) has to be put into relation with the delivered volume as a function of time (flow rate). The flow rates and delivered volumes corresponding to each speed setting are then easily calculated.

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.
