LT Syringe Pump - TriContinent

LT Syringe Pump

We put the best materials and designs together using manufacturing processes to ensure optimum alignment of the drive, seal and syringe barrel. The end result is a high value syringe pump that is “elegant in its simplicity.” The LT syringe pump has all the accuracy and precision characteristics of ordinary syringe pumps without syringe replacement schedules and user accessibility concerns. You enjoy longer instrument “up time” and the freedom to design instruments without consuming valuable working area.

Every aspect of the LT syringe pump has been specifically designed to assure trouble free operation for the life of the syringe pump.

  • NO calibration required
  • NO high fluid pulsation

  • NO leaking bellows or diaphragms

  • NO ceramics that seize when dry

  • NO consumable syringes

Along with a full range of syringe sizes, there are valve, encoder and electronic options to meet almost every instrument application and budget.
