Quality Syringe Filters

All Cronus syringe filters are QC tested in an independent laboratory meaning they conform to the highest quality standards. This ensures every batch of filters offers consistency, reliability and membrane integrity, week after week, year after year.

Additionally, samples of all the filter batches and membranes are held for 24 months from production for reference. This enables your current batch to be tested in our labs under your conditions should you require assistance with an application.

Tested to Certified Quality Standards

Every single batch of   Cronus syringe filters has to pass a rigorous set of tests:

• Bubble Point — tests the pore size of the filter membrane again.

• Water Breakthrough — confirms the pore size and tests the back-pressure required to pass a water sample. This will be different for hydrophilic and hydrophobic membranes.

• Burst Pressure — tests the correct mounting of the filter membrane and the membrane strength.

• Filter Integrity — tests the actual filter fabrication and moulding to ensure that the housing rating is correct.

• HPLC Extractables — tests each membrane to ensure low extractable levels and consistency from lot to lot.

• Efficiency — tests the overall efficiency of the filter using known standards. Cronus filters are rated for high sample volume and filtration efficiency.

• Filter Retention Volume — tests for residual sample left in the filter after use.

The full laboratory test results and certificate of compliance for any filter are available on request.

HPLC results can only be as good as the weakest component so consistent and reliable sample filtration is essential. Cronus syringe filters represent a new standard in sample preparation excellence giving you complete confidence in your results.
