The TV dipslide features two different agars (culture medium). This dipslide has plate count agar on one side which measures / grows total viable organisms. The other side of the dipslide has VRBG agar which measures / grows enterobacteriaceae.
Plate Count Agar - A general growth medium that detects a viable / total count in food and water. Mainly used in the dairy industry.
VRBG - Detects enterobacteriaceae. Used predominantly in food safety applications. Growth shows as pink / purple colonies.
This dipslide also contains neutralisers (germicide inhibitor). Neutralisers are added to agars to 'neutralise' the effect of disinfectants / germicides. This is useful if you wish to test the efficacy of disinfectants / germicides.
If your sample contains microbiological contaminants, colonies will grow on the dipslide agars.
To use, you can either dip the slide into your sample, swab onto the dipslide or press the slide against a surface. Once your sample has been transferred onto the dipslide, you then incubate the dipslide. After incubation, you can then count the colonies / spots and compare with the chart provided. A step by step pictorial guide can be found below.
Applications:
- Food safety
- Dairy
- Farming
These dipslides come in a pack size of 10 slides per box. The slide has a flexible paddle and is within a shatterproof container.
How to use the TV 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.
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.
TV 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.
