micrógel™ Multi-Organism CRM

micrógel™ Multi-Organism CRM’s can be used to QA multiple routine food microbiological analyses from a single standard. Save time, money and effort by minimizing the number of controls required or eliminating the need to manage numerous cultures in-house.

micrógel™ Multi-Organism CRM's  are water soluble discs containing viable microorganisms at known levels. All of the microbiological CRM’s are prepared from genuine NCTC cultures and are less than 5 passes from primary culture.

Certified using approved food testing methods (AOAC, BAM Compendium) in ISO 17025 accredited laboratories. This unique, rigorous approach to certification yields defensible data specific to selective methods and different sample types.

From the one source of CRM, you can now test a wide range of rehydratable plates such as 3M™ Petrifilm™ :

• Aerobic Plate Count

• Total Coliform Count

• E.coli Count

• Enterobacteriaceae

• S. aureus Count

• Yeast and Mould

   

Advantages:

• Easy to use

• No pre-incubation

• Homogenous

• 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:

1. Allow the sample vial to room temperature for 5 minutes

2. Transfer the sample disc to 90mL of sterile Butterfield’s Buffer by inverting the open sample vial above the buffer vial.

3. Cap the buffer vial, swirl, and allow the sample to dissolve for 10-15 minutes at room temperature.

4. After 10-15 minutes, shake the sample gently and inspect for complete dissolution.

5. If the sample is not completely dissolved, wait 5 minutes and gently shake again.

6. This is your standard for analysis. If food matrix supplementation is required, it should be performed at this time.

7. Use 1mL plate inoculation. Units are reported in CFU/mL.
