Custom & Complete Media Solutions

Gemini provides complete cell culture media including sera that are customized to meet the specific needs of our customers. We can provide the same lot of serum and reagents over multiple production runs. The product can be provided with any serum concentration that our customers request. Our Customer Service Department is available to provide special quotations for the desired complete or customized media product on request.

General Information

In order to provide our customers with high quality, custom media products we need the following key information:

Media formulation or specific modification of existing formulation. Is it a proprietary formulation?

Are there any serum components included? We need to make sure that if the media requires serum, that the customer provides serum lot requirements or has the chance to test serum lots to determine which one they would like to have added.

Testing specifications: What tests are required and what are the test result specifications. Oftentimes, testing can determine the turn-around time. (pH, endotoxin, sterility, osmolality, mycoplasma, etc.)

Packaging requirements: Fill size, storage requirements.
