Filta-Max xpress® system for Cryptosporidium

23 July 2014

In June our Microbiology Laboratory at Horsley was granted UKAS accreditation for the Filta-Max xpress® method for the analysis of Cryptosporidium.

The Filta-Max xpress® system offers a fully automated elution stage which takes 113 seconds compared to a minimum of 12 minutes (previously achievable using the old Filta-Max method).

The Filta-Max xpress® still uses foam technology to trap Cryptosporidium during the sampling process. In the laboratory the Filta-Max xpress® system (pictured above) uses air pressure to force specially designed buffer through the filter to wash out any potentially trapped Cryptosporidium. The analysis from this point onwards remains unchanged.

The new automated system aims to improve recovery, consistency and reliability whilst saving time and labour. You can find out more about this instrument by visiting the manufacturers website here.
