PURASPIN® lab filter
PURASPIN® – The Centrifuge and Vacuum lab filter. Testing depth filtration up to 20 mL.
Depth filtration is one of the most efficient and cost-effective methodes of filtration. Thanks to PURASPIN®, this technology can now be used in a range of applications up to 20 mL for alluvial and depth filtration in the biological as well as in the beverage sector.
PURASPIN® enables you to quickly and efficiently test different depth filters or quickly purify a small amount of liquid in an early stage of the process. The usage is simple. Just insert the spinner into standard 50 mL centrifuge tubes (Labcon® SuperClear® 50 mL tubes) or use with a Luer Lock adapter for vaccum connection. The liquid is then filtered using a centrifuge or vacuum.

The advantages of PURASPIN® lab filter:
Extremely easy to handle.
Pre-assembled filter units can be applied in the centrifuge or by vacuum without further preparation.
Fast results.
After just one filtration run, which takes only a few minutes, you have a conclusive result.
Several samples can be tested at the same time.
The available filter sheets of different types can be tested in one step and thus under the same conditions.
No additional filter accessories required.
With the spinner (plus the centrifuge tube when used in the centrifuge) you have everything you need for the filtration run in the lab.
