Longer Pumps range of Syringe pumps are mainly for lab or OEM use.

The laboratorial range of syringe pumps are available to infuse or withdraw liquids with syringe sizes from as little as 1 μL up to 100 ml.

Programming options allow for complex infusion or withdrawal processes and can include stepped functions, constant or ramped speed as well as a trigger dispense or periodic dispense.

Output signals from the pumps can show when a process has started or stopped as well as the direction. Further communication protocols can exist over RS232 or RS485.

A high pressure syringe pump allows for a linear force great than 450N.

OEM syringe pumps allow for single and multi-channel applications.

Principle


Laboratorial Syringe Pump - Working Principle

Syringe pumps are able to both draw in (withdrawal) or push out (infusion) a liquid through a syringe. The volume of the liquid will be based on the size of the syringe and the method of the withdrawal or infusion will be based on the syringe pump used.

Fluid ejects at a very accurate rate when used in infusion mode. The pusher block on the syringe pump pushes against the plunger on the syringe.

When the syringe pump us used in withdrawal mode, the pusher block moves in the opposite director so that the syringe plunger is pulled and draws fluid into the syringe.

Laboratorial Syringe Pump Configuration


Laboratorial Syringe Pump - The Configuration

The type of syringe pump can be selected dependant on the process and application. A simple syringe pump can dispense a given volume over a set period of time. Programming options allow for complex infusion or withdrawal processes and can include stepped functions, constant or ramped speed as well as a trigger dispense or periodic dispense.

Many different syringe types exist dependant on your volume or material. Smaller volumes use glass syringes where as larger volumes use both plastic or stainless steel syringes. Stainless steel syringe’s offer both Viton or Perfluoro seals as well as being for use with higher process pressures.
