Liquid Chromatography
Perista® Pump

Purpose
  • Deliverying liquid by peristaltic method (Flow rate 0.1-1500mL/Hour)
  • Solution sending pump for chromatography
  • Solution sending pump for fermenter culture
  • Solution sending pump for perfusion culture/perfusion fixation 
  • Solution sending pump for chemical liquid reflux experiment 
  • Pump for prepared liquid 
  • Pump for perfusion/reflux 
  • Also this pump is available for wide variety of purpose at research institute, production plant and so on 
Principles

A soft tube made of silicon is squeezed by rollers and liquid is delivered. The product name "Perista® Pump" is a registered trademark of ATTO Corporation. Liquid contacts only the inside of tube so that it is not polluted and sent under aseptic condition. Also, tube is an only part to be cleaned after use.

Cautionary notices of long time continuous operation with Perista Pump 

  • Consumption of silicon tube 
  • Abrasion of the rollers 
  • Abrasion of the internal gear (at high load) 

Please replace to new parts when it is worn out.
