Method validation and verification of Petrifilm® has never been so easy with the use of the new micrógel™ CRM's. As the CRM's were designed and certified specifically for the Petrifilm® plates, the resulting counts from the micrógel™ discs are always within the countable range of the test method.
A number of 3M™ Petrifilm® products are covered within this range:
Easy to use
Stable for up to 18 months (varies between products)
Reproducible to <5% RSD
Manufactured from pure cultures under an ISO Guide 34-accrediated QA system
Certified in an ISO 170225 accredited laboratory
All micrógel™ products are supplied with a Certificate of Analysis
Instructions for use:
Allow the sample vial to room temperature for 5 minutes
Transfer the sample disc to 90mL of sterile Butterfield’s Buffer by inverting the open sample vial above the buffer vial.
Cap the buffer vial, swirl, and allow the sample to dissolve for 10-15 minutes at room temperature.
After 10-15 minutes, shake the sample gently and inspect for complete dissolution.
If the sample is not completely dissolved, wait 5 minutes and gently shake again.
This is your standard for analysis. If food matrix supplementation is required, it should be performed at this time.
Use 1mL plate inoculation. Units are reported in CFU/mL.
