We manufacture many different types of prepared culture media plates that can be used for bacterial identification and isolation by veterinarians and technicians. Single (mono) chamber plates with one media type to multi-chamber quad plates with four media types are designed to be species specific and selective for both gram-negative and gram-positive organisms.

For example, our Mastitis Quad Plate offers a combination of four different media types for overnight identification of mastitis pathogens. These plates contain Heart Infusion Blood Agar (BAP), TKT/FC, MacConkey, and Baird-Parker or KLMB media.

After a sample is applied to the plate and incubated, combinations of no growth or positive growth characteristics on the various media types allow for the differential identification of the bacteria. This process is fast, inexpensive and provides meaningful results. This allows "identification before medication", to help assure the appropriate use and proper selection of antibiotics.

A list of our Multiple Chamber Plates and a rational for use is presented below. Charts of organisms and their growth characteristics on selective media are also available to all our customers. We have a page showing positive results when Staph aureus was plated on various Wolff Products Quad Plates. Click here to see these remarkable results and for tips on sample collecting.

Basic Tri-Plate: BAP, CNA, MacConkey

An all purpose plate. BAP for all organisms. CNA for gram-positive organisms. MacConkey for gram-negative organisms.

Mastitis Quad Plates: BAP, TKT/FC, MacConkey, Baird-Parker or KLMB

For the culture of milk using an individual quarter, cow or mixed sample. BAP for all organisms and hemolysis. TKT/FC for the growth, separation and identification of streptococci. MacConkey for growth, separation, and identification of gram-negative bacteria. Baird-Parker or KLMB (depending on client preference) promotes growth and separation of staphylococci while inhibiting other organisms.

General Quad Plate: BAP, CNA, MacConkey, EMB

A general purpose plate for the initial culturing and identification of gram-positive and gram-negative organisms. BAP for growth of all organisms and determining hemolysis. CNA for the separation of gram-positives. MacConkey and EMB for the separation of gram-negatives.

Standard Quad Plate: BAP, Brilliant Green, MacConkey, CNA

A general purpose plate for the initial culturing and identification of gram- positive and gram-negative organisms. BAP for growth of all organisms and determining hemolysis. CNA for the separation of gram-positives. MacConkey and Brilliant Green for the separation of gram-negatives.

Urine Quad Plate: BAP, CLED, CNA, MacConkey

A plate designed for the growth, quantification and identification of urinary tract infections. CLED media is a media designed for the growth and enumeration of organisms in urine. BAP is for detection of hemolysis. CNA promotes gram-positives at the expense of gram-negatives. MacConkey supports growth of gram-negatives with identification.

Staph. Quad Plate: KLMB, Baird Parker, Purple, Mannitol Salt

A plate to identify staphylococci. Designed after preliminary identification of staph where further separation for identification is needed.

Gram-Negative Tri-Plate: BAP, Brilliant Green, MacConkey

A plate for the basic separation and identification of gram-negative organisms. BAP for all organisms. MacConkey and Brilliant Green for a initial separation of gram-negatives.

Gram-Negative Quad Plate: BAP, Brilliant Green, MacConkey, EMB

A plate designed to further identify gram-negative organisms. Can be used after preliminary separation of gram-negatives for further identification.

We also have a basic Bac-T-Kit containing sterile swabs, transport media,enrichment broth,a tri plate (BAP, CNA and MacConkey), distribution fluid, and a Mueller-Hinton Blood agar plate which can be used with sensitivity disks (ordered separately).

In addition, we have many other medias, agars and fluids filled into mono-plates and tubes. Please see our price list (below) for a complete list of these products.
