About the plate count (pca) ttc + violet red bile glucose (vrbg) (neutralisers) dipslides (box of 10)
The TTV dipslide features two different agars (prepared culture medium), plate count agar on one side and VRBG agar on the other side. This Dipslide measures a total count on the front side and enterobacteriaceae count on the other. If there is bacterial contamination in your sample, colonies / dots will grow on the agar.
Plate Count Agar with TTC - A general growth medium that detects a viable / total count in food and water. Mainly used in the dairy industry. This agar includes TTC red spot dye which means that the colonies grow as red spots, making them easier to view and count.
VRBG - Detects enterobacteriaceae. Used predominantly in food safety applications. Growth shows as pink / purple colonies.
These dipslides come in a pack size of 10 slides per box. The slide has a flexible paddle and is within a shatterproof container.
What are dipslide neutralisers?
The TTV dipslide contains neutralisers. Neutralisers are added to agars to 'neutralise' the effect of disinfectants / germicides. The neutraliser aids in the recovery of surviving / viable organisms that have been damaged but not killed by cleaning chemicals. This is useful if you wish to test the efficacy of cleaning agents. The neutraliser will help you get a more accurate result without the efficacy of your cleaning regime being overestimated.
TTV Dipslide Applications:
- Food safety
- Dairy
- Farming
How to use the TTV dipslides
In Liquids
Simply remove the dipslide and immerse in the sample for approx 10 seconds. Remove dipslide and allow to drain 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).
Surface testing
Remove the Dipslide from the container and press against the surface for approx 10 seconds. Replace the slide back into the tub 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.
Step 1 : Remove slide
Carefully remove the sterile Plate Count TTC / VRBG + neutralisers dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).
Step 2 : If Surface Testing
For surface testing, press the Plate Count TTC / VRBG + neutralisers onto the surface. If needed, place a finger on the bottom of the slide (on the plastic, not the agar) to apply extra pressure.
Step 2 : If liquid testing
For liquid testing, immerse the Plate Count TTC / VRBG + neutralisers dipslide into the fluid for 10 seconds then remove and allow to drain for a few seconds.
Step 2 : If swab testing
Apply a sample of the test substance to a sterile swab and gently apply to the agars.
Step 3 : Incubate Slide
Label the tube with the included stickers then place the slide into an incubator and allow to incubate.
Step 4 : Compare results
Count the amount of colonies that have grown on the slide and compare them to the comparison chart provided.

Flexible Paddle
Each dipslide features a virtually unbreakable and flexible paddle allowing for even, full surface testing.
Easy Run Off Design
Due to the design of the dipslide, fluids will drain off quickly during testing.

Side Indicator
One side of the slide will have a circle indicator so you know which side was used for testing which type of contaminant.
