About the vrbl (violet red bile lactose) + vrbl (violet red bile lactose) dipslides (box of 10)
VRBL agar (violet red bile lactose) tests for coliforms (Enterobacteriaceae and other lactose fermenting organisms) in food and environmental samples. This can include detection of contaminants such as E Coli, Klebsiella and Escherichia.
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.
Using the VRBL Dipslide
Testing with this slide would be best conducted with the patient giving a urine sample which the dipslide can then be immersed in.
Step 1 : Remove slide
Carefully remove the sterile VRBL 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 VRBL 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 VRBL 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.
Industry sectors include
- Dairy and other food products
- Animal Feed
Coliforms will produce red / purple colonies on the slide.
