These dipslides feature two different agars (culture medium). They have Plate Count Agar on one side and VRBG Agar on the other side. They test for total viable count and enterobacteriaceae.
Plate Count Agar - This agar is used to test for viable organisms in dairy products and water. It offers a total count.
VRBG Agar - This is selective for Enterobacteriaceae (this includes coliforms). VRBG agar is often used in food safety applications. Growth shows as pink / purple colonies.
If your sample contains bacteria, colonies will grow on the dipslide. To interpret your results, you will need to count the colonies and compare with the chart provided.
These dipslides come in a pack size of 10 slides per box. The slide has a flexible paddle and is within a shatterproof container.
Industry sectors include
- Dairy
- Food safety
- Animal feed
How to use the PCV dipslides
Simply remove the dipslide and immerse in (or press against) the sample for approx 10 seconds. Remove dipslide and allow to drain (if necessary) for a few seconds, then replace the slide back into the tube and incubate for a minimum of 24 hours (up to a maximum of 48 hours).
A comparison chart is included so you can easily compare your results.
Carefully remove the sterile Plate Count / VRBG dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).
For surface testing, press the Plate Count / VRBG dipslide onto the surface. If needed, place a finger on the bottom of the slide (on the plastic, not the agar) to apply extra pressure.
For liquid testing, immerse the Plate Count / VRBG dipslide into the fluid for 10 seconds then remove and allow to drain for a few seconds.
Apply a sample of the test substance to a sterile swab and gently apply to the agars.
Label the tube with the included stickers then place the slide into an incubator and allow to incubate.
Count the amount of colonies that have grown on the slide and compare them to the comparison chart provided.
PCV Dipslide Features
Each dipslide features a virtually unbreakable and flexible paddle allowing for even, full surface testing.
Due to the design of the dipslide, fluids will drain off quickly during testing.
Each slide has a handle built into the lid that is recessed to help keep your fingers dry during testing.
One side of the slide will have a circle indicator so you know which side was used for testing which type of contaminant.
Each dipslide is dual sided to allow multiple contamination testing with one test.
Each agar is thick (approx 4mm) and raised above the dipslide to allow for easy surface testing.
