About the plate count (pca) ttc + violet red bile glucose (vrbg) dipslides (box of 10)
These dipslides have Plate Count Agar TTC on one side and VRBG Agar on the other. The TTC (red spot dye) on the plate count side makes colonies easier to view and count as they appear as red spots. Plate Count Agar is for total count applications (ideal for dairy testing) and VRBG Agar tests for Enterobacteriaceae.
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.
Easy Run Off Design
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.
Thick Reliable Agar
Each agar is thick (approx 4mm) and raised above the dipslide to allow for easy surface testing.
Plate Count Agar - This agar is used to test for viable organisms in dairy products and water. It offers a total count and contains red spot dye. Colonies will appear as red spots.
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.
How to use the PCTV 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.
Step 1 : Remove slide
Carefully remove the sterile Plate Count TTC / VRBG 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 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.
Step 2 : If liquid testing
For liquid testing, immerse the Plate Count TTC / VRBG 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.
