​Te​ledyne LABS​ HLf -Series syringe pumps conform to safety standards for use in UL Class I, Division 2, Groups A B C & D, T4 environments. The HLf syringe pumps give you the same accurate, predictable flow and pressure control while meeting the safety requirement. The hazardous location rating is achieved through internal design modifications including the use of brushless DC motors and non-contact switches. This approach eliminates the need for purge boxes or other additional safety devices. Wetted materials are compatible with most aqueous and organic liquids, corrosive solutions, heated substances, liquefied gases, viscous fluids, or slurries and pastes.​​

​Frequently Asked Questions​

W​​hat is a syringe pump and its use?

A syringe is a mechanical device that uses a plunger to extract a liquid from one location and move it to another, such as for the application of mass spectrometry. In the laboratory, syringe pumps are used to distribute precisely measured liquids into scientific instruments for experimentation and production.

What are the different types of syringe pum​​ps?

Pumps can have a single syringe or multiple syringes. Primary types of pumps include:

  1. Infuse-only 
  2. Infuse and withdraw 
  3. High-pressure 
  4. Continuous flow independent channels: a dual syringe pump

What are the common prob​lems with syringe pumps?

Because syringe pumps have moving parts, those parts can wear out over time. Many are computer driven, and user error or software problems can occur. 

What is the me​​​dical name for syringe pumps?

Infusion pump.
