The TVLN dipslide has plate count agar on one side and VRBL agar on the other side. This dipslide contains neutralisers (germicide inhibitor) for disinfectants present in the sample. Neutralisers help provide accurate readings in cleaning efficacy tests.
This Dipslide measures a total count on one side and enterobacteriaceae (specifically coliforms in food products) count on the other.
It comes in a pack size of 10 slides per box. The slide has a flexible paddle and is located in a shatterproof container.
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.
Both agars include neutralisers for common germicides. This helps the user assess the effectiveness of cleaning regimes.
Plate Count Agar - A general growth medium that detects a viable / total count in food and water. Mainly used in the dairy industry.
VRBL - For the detection of coliforms in food products. Produces red-purple colonies.
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 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 / VRBL + neutralisers dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).
For surface testing, press the Plate Count / VRBL + 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.
For liquid testing, immerse the Plate Count / VRBL + neutralisers 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.
