Technical Service Consultants have been selling and manufacturing products for use in the microbiology laboratory for over 25 years.  More recently we have been servicing the requirements of the food and pharmaceutical industries for microbial environmental sampling and testing.

Enviroscreen is the complete microbiology monitor for hygiene, sterility and quality, which also includes a range of complementary elements designed to support the microbiological QC and QA procedures of plant, process, product and personnel.

Key Benefits

Enviroscreen sponges have been shown to give a superior recovery of Listeria spp.
Simple to use.
Gamma Irradiated.

Environmental Sampling Sponges



Enviroscreen sponges can be used for surface sampling and semi quantitive analysis.  Blue Enviroscreen sponges are dosed with neutralising buffer or Butterfields diluent, in a medical grade bag, containing either a resealable mini grip bag or 100ml blue plastic  container.

Surfaces Can Be Sampled By:

Pressing the sponge down onto the surface - then onto a suitable agar plate which will give a CFU count/50cm2.

Sampling a set area - the sampling template TS15-T is ideal for this purpose covering a 100cm2 area.  The sponge can then be treated in a stomacher or manually squeezed so that plate counts can be performed.

Sampling an area and incubating the sponge in a suitable enrichment broth - listeria broth, buffered peptone water etc.  to isolate specific organisms.

Drag Swabs



In response to the growing demand for more effective ways to test for Salmonella and other micro-organisms in poultry breeding houses and other environments, Technical Service Consultants have developed a simple to use drag swab.

Drag swabs have been shown to be the most effective method of sampling and monitoring Salmonella contamination in poultry breeding houses and to be a highly effective tool for the broad scale detection of Salmonella contamination at farm level.

The pack consists of a medical grade bag containing an 8 x 2.5cm sponge attached to a 30cm nylon cord.  the packs are sterilised using gamma irradiation.  Plastic bulldog clips to attach swab to clothing are available separately.

Maximal Recovery Diluent



A transport swab system available as a semi-solid medium or liquid using a pure viscose tip swab.

MRD provides the protective effect of peptone with the osmotic support of physiological saline whilst low peptone concentration does not cause multiplication of organisms for up to 2 hours.

Swab Sampling Kits



Surface sampling kits are provided as a single peel pack containing a sealed tube with neutralising buffer and a capped swab.  The surface to be sampled can be tested using the swab dry or pre moistened from the buffer in the tube.

The sampling template can be used to provide an accurately defined 100cm2 sampling area, allowing for the assessment of colony forming units per cm2.  Two types are provided;-

Pure Dacron is a totally synthetic fibre.  the tip is heat treated to ensure adherance to the shaft whilst in the buffer.

Alginate fibre will dissolve in the buffer alowing release of the organism collected onto the swab during sampling.
