Syringe Pumps and Rotary Valves

OEM Syringe Pumps for In Vitro Diagnostics Instrument Manufacturer

TriContinent provides a wide range of various syringe pump modules. They are well known for their long-lasting and exceptional quality, and are designed for precision and accuracy. They offer a unique combination of low flow and low pulsation for various applications including IVD (In Vitro Diagnostics).

The industry standard are the C-Series syringe pumps which provide the highest accuracy and precision, while the AccuPump and the BasePump are affordable solutions for all standard pipetting tasks. The available syringe sizes vary from 50 µl up to 12.5 ml (C-Series). TriContinent also offers syringe pumps as a seamless replacement for industry standard syringe pumps using the Cavro® protocol.

How Do Syringe Pumps Work?

TriContinent’s syringe pumps work by filling a syringe with the desired medium (aspiration) and emptying the syringe (dispensing) after changing the flow path with a valve. They consist of three components: a syringe, a drive mechanism and a valve which is often a so-called rotary shear valve. The simplest case is a 3-port valve where one port is connected with the syringe, another port acts as the inlet and the third port acts as the outlet port.

What does the workflow look like?

  1. The plunger moves up and the syringe is emptied – the system is now at its starting point.
  2. The valve switches to the inlet position.
  3. The plunger moves down and the syringe is filled with medium (aspiration).
  4. Then the valve switches to the outlet position
  5. The plunger moves up and the desired volumes are dispensed

The process repeats until the syringe is completely empty, then the new medium has to be aspired.

TriContinent’s rotary valve can last for up to four million switching cycles, which has been shown during a competitive valve study. The syringe and the tubes have to be replaced from time to time, while the drive mechanism is designed to work for several years.

TriContinent’s Syringe Pumps Applications

At TriContinent, we customize our products to the exact requirements of our client’s application. We have a long and successful history of providing application specific OEM syringe pumps for our customers. These vary from simple modifications of standard syringe pumps or liquid handling (XYZ) robots, to melding the key features of existing technology platforms. We also provide completely custom designed syringe pumps and accessories to reduce service costs and field failures in our customer’s existing instruments.

All normal aspiration and dispensing operations expected from an OEM syringe pump module can be accomplished. The stepper motor driven syringe will accurately and precisely handle fluids from a few microliters to 12.5 milliliters. The syringe drive arm can be easily back driven, making syringe installation or replacement extremely quick and easy.

TriContinent syringe pumps are ideal for experienced IVD instrument manufacturers who are looking to maximize the investment they have already made in their existing instrumentation.

TriContinent syringe pumps utilize standard communication protocols and mounting configurations used by other compact syringe pump designs, thereby eliminating expensive and time-consuming re-development.

TriContinent Provides Customized Solution for Next-Generation Sequencing Leader

A leading developer of next generation sequencing (NGS) technologies turned to TriContinent to help them evolve their equipment to perform precise targeted resequencing, small-genome sequencing, and in-vitro diagnostics (IVD). The company’s goal was to incorporate a high-precision syringe pump to efficiently handle patient samples and reagents with accuracy and a low risk of carryover.
