In addition, we have expertise with aerobes, anaerobes, and spore formers. We are BSL1 to BSL3 capable and are approved for working with Select Agents and Toxins.

Custom Product Fills

Whether you want one of our standard products in quantity in another size fill, or you need manufacturing and a custom fill of your own product, we are able to provide these services at reagent or GMP grade.  Custom fills require a minimum quantity commitment and may take several months to schedule.
