Why use HardyVal?

HardyVal assesses the risk of microbial contamination of your CSP’s (compounded sterile preperations) according to USP <797>.

How do I determine which kit or products are right for me?

Choose from five pre-assembled kits for ease of use or create your own aseptic technique challenge with our à la carte line of HardyVal media and products.

 USP <797> states, in part, “When performing these testing procedures, use the most difficult and challenging compounding procedures and processing conditions encountered by the person during a work shift (e.g., the most manipulations, most complex flow of materials, longest time to compound), replacing all the components used in the CSP’s with microbial growth medium.”
