National Institute of Health - USA |
| 'we have been using the B-Series machine for 5 years now and find it extremely efficient at disrupting a wide range of micro organisms, from insect cells to yeast Pichia Patoris. I would definitely recommend it to the Scientific Community.' |
|
'We are very happy with the One Shot cell disrupter and find it to be very efficient, easy to use and gives reproducible results' |
| University of Cambridge, Department of Pharmacology - UK |
|
Tokyo University - Japan |
| 'Basic Z gives us the high-quality bacterial cell extracts we need for our research' |
|
'Our One Shot model is highly effective and easily disrupts Fungi such as Aspergillus' |
| Syngenta - UK |
|
Astex Technology - UK |
| 'We purchased the 2.2kW cell disrupter from Constant Systems 6 months ago and we are very pleased with its speed and efficiency of disruption (E-Coli/Yeast). It has proved to be a very reliable machine! The training was comprehensive and effective. Well done!' |
|
'At Astex, the Constant Systems Cell Disrupter is mainly used for bacterial cells disruption (usually E. coli). Although it has additionally been used for insect and yeast cell lysis. The disrupter gives good lysis of E.coli. When insect cells are lysed with the system the breakage is good.' |
| Veterinary Laboratories Agency, UK |
|
University of Strathclyde, UK |
| 'quick and simple to perform, it did not generate high temperature' |
|
'robustly designed... easy to maintain' 'the cell disruptor gave reproducible results... fast and reliable' |
| Bristol University (UK) |
|
University of Wales, UK |
| 'Our group and several others are regular users of the Constant Systems cell disruptor primarily for bacterial cells. We fine it to be an extremely efficient and robust piece of equipment, which is now an essential part of our protein production facility.' |
|
'high levels of containment... effectively cooled' 'easy to operate... easy control of the operating pressure' |
| Astra Zeneca (Sweden) |
|
University of Novara (Italy) |
| 'We routinely use the Constant Systems cell disruptor for insect cells, bacteria and yeast cells. We are very happy with its performance and ease of use' |
|
'The Constant Systems Basic Z disruption system is our first option for bacterial cells lysis during large-scale protein purification procedures.' |
| University of Glasgow (UK) |
|
University of Edinburgh (UK) |
| 'The Constant Systems cell breaker gives highly efficient breakage of yeast cells and is our best option for isolating membranes from yeast' |
|
'We have had two Constant Systems cell disrupters in our fermentation suite for several years. In this time dozens of users from diverse backgrounds have employed the cell disrupters to break tens or hundreds of grams of cells per use - all have obtained excellent breakage, and subsequently good yields of their proteins. New users require minimal instruction with these conceptually simple machines, cleaning is straightforward and service by Constant Systems is second to none.' |
| Russian Cardiology Department (Russia) |
|
Wageningen University (The Netherlands) |
| 'Constant Systems cell disrupter is successfully used at our Experimental plant mainly for bacterial cells. This efficient and reliable piece of equipment became an important part of our enzyme purification unit. Russian Cardiology Research and Production Complex' |
|
'The cell disruptor from Constant Systems is an easy to use and simple piece of equipment. It proved a very useful tool for the fast and efficient lysis of gram positive as well as gram negative bacterial cells. It has become an important instrument in our daily experimental routines. ' |
| NueTech Pharma (UK) |
|
De Montfort University (UK) |
'The Constant System provides safe, fast, simple operation, and more over, excellent results in cell disruptions. It is also a very reliable equipment standing up for regular and frequent usages.'
|
|
'We have used the Constant Systems machine over several years for cost effective disruption of Yeast cells. As far as we know at the time of purchase and now there is not a better machine for our application.' |
| Lipoxen |
|
|
| 'Since Lipoxen aquired this equipment it has been a pleasure to work with, the high pressure homogenisation (40,000 psi) has been invaluable in the preparation of SUV liposomes from saturated phospolipids. In short this equipment has made our job of Liposome production simple.' |
