Biosera culture medium formulations are manufactured following original publications and standards set by the Tissue Culture Association and accepted formulations.

Custom Made Media - In addition to standard media, it also possible to custom make media according to your personal requirements.  Let us know the components needed and the quantities that correspond and we will produce this to your requirements. There may be a short delay for this service.

Quality Assurance - All of the chemicals, raw materials and equipment that we use is of the highest quality. All new batches of chemicals are introduced in the process after stringent QC.

The water used for media preparation is of WFI quality, produced in several steps including centrifugal distillation. The conductivity is measured in line and the water is always freshly processed and cooled down to 20°C before adding the powder.

Equipment and Conditions - The equipment used for the manufacturing of powdered and liquid media has been designed to incorporate chemically inert materials, which will not contaminate the final product. Humidity and temperature are controlled constantly to guarantee that all chemicals are ground into fine powder.  Being passed twice through 0.2/0.1 µm pore size sterile filters carries out the liquid media sterilisation.

Batch Size - Batch sizes for powdered media range from 1 to 10,000 Litres, for liquid media from 1 to 2,000 Litres.

Storage and Stability - Powdered media are stable for 3 years when stored at 2-8 °C in their original containers and in dry, dark conditions. Heat, light and humidity can greatly affect the performance of powdered media therefore we recommend that powder be stored correctly if not used entirely. All liquid media formulations are stable for up to 2 years (1 year if they contain L-Glutamine). They must be stored at 2-8°C in the dark. Media concentrates are stored at 8-10 °C and are stable for 1 year at the original pH. Each product is labelled with its required storage conditions and expiry date.
