  Micro Pump OEM Module TS Series - Features


Micro Pump OEM Module TS series

By and large, the small precision plunger pump is one of the most versatile and demanded for high reproducibility and accuracy. Downsizing is the needs of the times, and the pump modules for systems cannot be an exception. Increasingly demanded are lesser and lesser volume of reagents and samples as well as high throughput and multi-function in the system. As the fluidic flow volumes get smaller, all of the mechanisms of the pump will need to be smaller, including micro-scale dead volumes, and high-precision machining is executed to provide unparalleled accuracy and high reproducibility.

The plunger material is available from zirconia, sapphire, or stainless steel. The use of stainless steel plunger may sound strange in consideration of its chemical compositions. However, the stainless steel is a material much more ideally suitable for high precision machining, and its drawback of containing some negative chemical compositions is offset with chromium nitride (CrN) treatment on the plunger surface. The CrN treated stainless steel plunger provides higher abrasion resistance, and chemical inertness equivalent to ceramic in addition to dimensional accuracy and surface smoothness, while its cost is much lower than sapphire.


 Features


High reproducibility. For example, CV 0.1235 % is the value from Model TS-MP22SPAC2020, when tested with an air bubble is fed into the mixture of water and methanol (7:3) filled in a 0.3 mm ID tubing, and the traverse distance is measured with an input of 40 pulses before the test starts and an additional input of 400 pulses (a plunger traverse of 2 mm) for dispensing 8 µl at a speed of 200 pps each for intake and dispensing.

Other features include...

  • Minimized jolting and high rectilinear stroke of plunger contributing to high reproducibility
  • Precision machined pitch threads of feed screws leading to high accuracy in dispensing volumes
  • Precision guide system alleviates load to motor, thus enhancing the service life of motor
  • Minimized dead volumes, e.g. as small as 5.7 µl (TS-MP18)
  • The UHMPE plunger seal for very long service life expectancy
  • High throughput yet compact (TS-MP110)
