BioWest media formulations are manufactured following original publications, standards set by the Tissue Culture Association and accepted formulations. These formulations may vary from these standards by substituting hydrated, chlorinated and/or the salt forms of certain compounds where such substitutions contribute to improved performance of the product.

Custom Made Formulations
The realisation and production of your personalised cell culture media compositions is another of our services. In your catalogue you will find a list of substances for cell culture media. Give us the list of components needed and the corresponding quantities 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 equipments that we use is of the highest quality. Inorganic chemicals are analytical, ACS, USP, EP, FCC grade or otherwise the finest grade available. All other components are evaluated by standards established by BioWest. All new batches of chemicals are introduced in the process after Quality Control. The water used for media preparation is of the best quality. It is of WFI quality, produced in several steps including centrifugal distillation and tested for endotoxin. The resistivity is measured in line and all values are monitored and stored by the Quality Control department. The water is always freshly processed and cooled down to 20°C before adding the powders.

Equipment and Conditions
All equipments used for the manufacturing of powdered and liquid media are made of chemical inert materials which will not contaminate the final product. For 20 years BioWest has produced for cell culture following strict environmental conditions regarding cleanliness and moisture. Humidity and temperature are monitored constantly to guaranty that all chemicals are ground into fine powder. The liquid media sterilisation is carried out by going through a 0,1 µm pore size sterile filter.

Batch Size
Batch sizes for powdered media range from 10 to 10.000 liters, for liquid media from 10 to 1500 liters.
