PMBi Dispensing Pump

Overview

Ginolis PMBi (Piezo Motor Bellows) pump technology, which is patented, offers highly accurate, non-contact liquid handling.

From 1000 µl all the way down to nanoliters

• The PMBi pump is made to accurately and repeatedly dispense volumes in the nanoliter range
• There are two models of the PMBi pump, which are distinguished by the volume size
  • <1% CV (>50 nL)
  • <3% CV (@50 nL)
  • <8% (@2.5 nL)

Features

• Flexible
  • From 1500 μL to 1 nL. The PMBi pump is accessible in a starter kit that is simple to use and can be integrated into automation platforms
• Intelligent
  • Pump pre-pressurization, automated monitoring of pressure stabilization during pre-dispensing, and an integrated pressure sensor for detecting clogs, leaks, and air in fluid lines
• Low maintenance
  • The PMB bellows system has no friction components, making it a pump with a very long lifespan and no need for seal replacement

Applications

Dispensing technology

• The highly accurate piezo motor that is connected to a bellows that contracts and expands forms the foundation of the Ginolis PMBi Pump
• The aspirated or dispensed volume is displaced by the bellows in a closed chamber as a result
• The PMBi pump has a ceramic tip and a solenoid dispensing valve to dispense quantities as small as 1 nl
• The user-specified amount of liquid is displaced by the dispensing pump. To release a drop, the solenoid valve is opened for a brief period of time (a few hundred microseconds). Up to 100 drops per second can be released by the pump
