Baird Parker + Violet Red Bile Glucose (VRBG) (neutralisers) Dipslides (Box of 10)

Baird Parker Agar and VRBG Agar for Staphylococci and Enterobacteriaceae with neutralisers. This slide offers a Staphylococci count on one side and an Enterobactericeae count on the other side. The addition of neutralisers means that these dipslides are ideal for assessing the efficacy of cleaning regimes.

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.

These dipslides come in a pack size of 10 slides per box. The slide has a flexible paddle and is located in a shatterproof container. 

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.

Recessed Handle

Each slide has a handle built into the lid that is recessed to help keep your fingers dry 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.

Dual Sided

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.

VRBG - Detects Enterobacteriaceae. Produces purple / pink colonies. A neutraliser has been added to this agar.

Baird Parker - This agar is selective for Staphylococci. Staphylococcus aureus shows good growth with black shiny colonies with white and clear zones. A neutraliser has been added to this agar.

How to use the BVN dipslide

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 Baird Parker / 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 Baird Parker / VRBG + neutralisers 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 Baird Parker / 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.
