Plan Ahead and Save Your Research Dollars!

After producing sterile custom L-Amino Acid defined laboratory animal diets for many years, Dyets  is now able to expand our sterile product line to the research community with sterile casein-based custom diets. These new casein-based diets are formulated with specially prepared, sterile casein.  Dyets stocks both specially prepared high nitrogen casein or vitamin-free casein for gamma irradiated diets. Sterile (by gamma irradiation) casein-based diets are available in pellet, powder, or liquid diet forms.

Gamma irradiation costs are typically in the $1100.00/batch range.  U.S.P. Sterility testing is available for an additional charge.  Please note the following additional information for ordering gamma-irradiated diets:

  • Gamma irradiation will require 21 business days.
  • Allow 7 business days for shipping (within U.S.A.)
  • All orders for gamma irradiated diets should be placed 2 weeks prior to irradiation. This will allow Dyets 10 days to prepare and package your diets before irradiation. Use catalog number 999503 when ordering.
  • Custom 1 kg vacuum packaging of sterile diets can be performed for $4.00/bag.

Our specially processed high nitrogen casein or vitamin-free casein for diets to be gamma-irradiated can be purchased separately (as an ingredient). Please call for pricing and availability.
