Redipor Group Cropped - 2

Cherwell Laboratories is a family owned business located in central England, near Oxford.

We have been manufacturing prepared microbiological media under the Redipor® name since the early 1980s. During this time the Redipor brand has built a strong reputation within the pharmaceutical industry for offering high quality products and a flexible, efficient service. Today, the Redipor product range of prepared media, gamma irradiated media and bottled broths and diluents forms the core of our business.

Poured Plates – A comprehensive selection of general purpose prepared agar plates available as 55mm petri dishes, 90mm petri dishes, 140mm petri dishes and contact plates.

Gamma Irradiated Media – Redipor irradiated media products are typically used within cleanroom facilities and benefit from extended shelf life. The range covers 90mm petri dishes, contact plates and 140mm petri dishes.
