NSI’s MicroVive™ is a Long lasting rehydration fluid which allows you to maximize usefulness of your microbiological reference cultures, especially when several controls are needed at the same time. MicroVive™ increases the value of CRMs via extended freezer storage without loss of viability. Conveniently packaged pre-measured portions of sterile fluid is formulated for maintenance of both bacteria and fungi during freezer storage at temperatures of -10°C or less. Recommend reducing temperature at a rate of 1°C per minute if storing hydrated cultures at -20°C and below. MicroVive™ has been validated at -10° to -20°C for up to 30 days. Viability was maintained at 50% or greater based upon internal testing in accordance with ISO 17025. Manufactured by NSI, an ISO 17034 accredited certified reference material producer. Available in two different volume options: 1.2mL or 9mL pre-measured portions, pre-sterilized, sold in packs of 20 vials.

MicrogelFlash™ Microorganism Product Viability Verification Method: MicrogelFlash™ microorganism viability was tested and verified throughout freezer temperature storage in the formulated lot of MICROVIVE™ fluid. Microorganism viability thoruout the storage period was verified by testing replicate samples on control media. 0.1-1mL of inoculated MICROVIVE™ fluid solution was plated on control media in order to obtain approximately 100 CFU in total for the plate count results. Control media for bacteria: Soyabean Casein Digest Agar, Tryptic Soy Agar (TSA), or TSA with 5% sheep/horse blood. Control Media for Yeast & Mold: Sabouraud Dextrose Agar. Subsequent analysis was performed according to the instructions provded via NSI Lab Solutions’ internal laboratory standard operating procedure. NSI SOP instructions provided for the respective control media in accordance with standard practice for the detection of bacteria or yeast and mold. NOTE: Aerobic bacteria incubation was performed at 35°C for 24 hours. Yeast/Mold microorganism incubation was performed at 26°C for 72 hours.
30 Day Cultural Response Verification
