Introduction
The EZ-Pak® Dispenser Curve provides portable, hands-free, high-speed
dispensing of ready-to-use, sterile, individually-packed membranes for
microbiological analysis of liquid samples.
The system is available in two versions:
•Powered by lithium ion battery (up to 10,000 membranes are
dispensed per charge)
•Powered by alternating current (AC)
EZ-Pak® membrane cartridges can be loaded into the EZ-Pak® Dispenser Curve
in less than 30 seconds.
The EZ-Pak® Dispenser Curve automatically collects the protective packaging.
The EZ-Pak® Dispenser Curve is designed to be used under standard clean
conditions and with traditional membrane filtration methods.
EZ-Pak® membrane cartridges contain 150 white, black, or green gridded 47-
mm or 50-mm diameter membranes, and can be used with the Microfil®
filtration system.
