1st November is our birthday!

Cherwell Laboratories is 40 this autumn!

Andy and Lawrence Whittard

Founded in 1971 by Lawrence Whittard as a veterinary diagnostic laboratory, we have certainly evolved over the years to dedicate our products and services to the validation of sterilisation processes. Our fully integrated product range for microbiological and Quality Assurance applications now includes the Redipor, DataTrace and SAS ranges, alongside our new range of Raven biological indicator products for process validation.

Recent years have seen us move to our current site in Bicester and we plan to further expand to increase our manufacturing and warehouse capacity so that we can continue to help our customers with their prepared media, environmental monitoring and process validation requirements.

Ask Cherwell!

How frequently should my air sampler be calibrated?

Cherwell Laboratories recommends every 12 months and we will send a reminder for the month it is due. For some situations local procedures demand more frequent recalibrations so Cherwell is happy to offer tailored recalibration date labelling and reminders on request.

If there’s anything that you’d like to ask us, we’d be happy to help. Just email us.

An 'Aspirational' Alternative

We have recently introduced the Daily-Head disposable aspirating head for microbiological air monitoring. Triple-wrap irradiated, this provides an always ready alternative to autoclaving stainless steel heads. Each batch of the Daily-Head is supplied with a certificate of sterilisation and conformity to satisfy cGLP requirements.

Suitable for use with the SAS Super, Duo-SAS-360 and SAS-Isolator air samplers, the Daily-Head is available as Contact Plate (RODAC) and 90mm Petri dish versions.
