micropelletRT

MicroPelletRT: A MicroPelletRT consists of a lyophilized pellet of a single microorganism strain with a defined mean assay value inside a plastic vial and one separate vial with 1ml rehydration fluid. Adding the reconstitution fluid to the pellet vial it forms a suspension with a defined assay value of 10-100 CFU/0,1ml as mandated by USP and Ph.Eur. for growth promotion tests.


A QUALITY ASSURANCE CHALLENGE FOR GROWTH PROMOTION TESTS ACCORDING USP/Ph.Eur.


The MicroPelletRT are a cost-effective alternative to labour-intensive dilution/colony count procedures.

After processing these preparations of lyophilized microorganisms as directed you will achive a quality assurance challenge as required by Ph.Eur./USP to perform growth promotion tests. MicroPelletRT can be traced back to ATCC reference strains and are not more than 4 passages away from the reference strain.


MicroPelletsRT have the following features:

  • Each MicroPelletRT is packed separately in a vial- this prevents any spoilage of the lyophilized preparation by humidity etc.
  • MicroPelletRT are easy to use: Simply unscrew the cap and rehydrate with the provided fluid. As MicroPelletRT are lyophilized and not just dried suspensions like other products currently available, they rehydrate instantly and can be used immediately.
  • Each pellet contains 100-1000 colony forming units (CFU'S), and when rehydrated with 1 ml it produces 10 doses of 10-100 CFU's/0,1ml. No additional dilution step is necessary!
  • MicroPelletRT are delivered in economical packs of 2 vials with one pellet/vial.
  • The neccesary quantity of rehydration fluid (1 vial of 1ml per pellet) comes automatically with the pellets.
  • MicroPelletsRT can easily be stored at 2-8°C.
  • MicroPelletRT does not require dry ice. Shipping costs are reduced.
