VoluPAC Tubes from Sartorius Stedim Biotech GmbH

Description

The VoluPAC tubes provide a fast, easy to use, reproducible and reliable alternative to manual cell counting. They are 15 times faster and 5 times more accurate (margin of error less than 5%).

The VoluPAC tubes enable the determination of the packed cell volume (PCV) in a cell suspension, resulting in absolute data correlating with parameters like protein content, cell count, metabolic activity and others.

The VoluPAC tubes are particularly convenient to work with, requiring neither special training nor sophisticated expensive machines - in contrast to automated cell counting devices.

Features:
Fast – 1 min centrifugation compared to 5-15 min counting under the microscope
Reliable – Less prone to statistical errors due to the high number of cells in the pellet
Reproducible – No user to user variations; no dilutions, manipulations, or calibrations are necessary
Convenient and easy to use – Even for inexperienced users, no elaborate training necessary
Works for all cell lines – No problems with cells forming microclusters
Allows parallel determination of many samples – Manual counting has to be performed sequentially
Compatible with standard rotors – No additional equipment required except a bench top centrifuge
Disposable – Does not afford preliminary cleaning steps
Cost effective – Compared to highly sophisticated techniques, particularly under concern of initial investment costs and maintenance
Provides absolute data – Irrespective of the actual volume of the cell culture
