The principle use for this product is in the testing of disinfectants and antiseptics. In 1989, the European Committee for Standardisation (CEN) set up a technical committee to produce harmonised test methods for disinfectants and antiseptics. The CEN standards provide a useful basis for disinfectant validation, and although alternative methods could be used for assessing disinfectant efficacy, following the same basic methods allows not only direct comparison between products but also comparison across various different laboratories. The adaptability of the methods - numerous validation studies based on the CEN methods have been accepted by both the European and US regulatory authorities - allows end- users to customise the methods to their specific requirements. Lecithin and polysorbate 80 (Tween 80) inactivate surface disinfectants (lecithin neutralises quaternary ammonium compounds and Tween 80 neutralises phenols, formalin, hexachlorophene and in combination with the lecithin ethanol). L-histidine, in combination with lecithin and Tween 80, neutralises aldehydes and formaldehyde generating agents. Sodium thiosulphate neutralises iodine and chlorine. -
Glucose agar allows for the detection of glucose fermentation (with or without gas production) as an identification test for Enterobacteriaceae (ISO 21528) and B.cereus (ISO 7932). It is further enriched by the addition of Yeast Extract. Bromocresol Purple is also included and acts as an indicator of glucose fermentation. -
For in vitro diagnostic use only. SW0005-M055-3 Strep B Swab Kit contains Lim Broth, a nutritious medium for the enrichment and transport of Group B streptococci along with a sterile swab suitable for collection of patient samples. The product may be used to preserve, transport, and enrich Group B streptococci that may be present in samples obtained from patients by use of the swab. Each pack also contains a sterile swab in an individual peel-pouch. The swab has a polystyrene shaft with a small viscose tip. The shaft has a breakpoint 78mm from the tip allowing the shortened swab to engage in the shaft capture device in the lid and ensure that the swab is removed from the tube when the cap is unscrewed. Lim broth is a nutritious, selective broth utilising the base formulation developed by Todd and Hewitt (1) for the enrichment of Group B streptococci. It is intended as a selective, enrichment broth for Streptococcus agalactiae that may be present is specimens. The device is primarily intended for use in screening pregnant women for the presence of S. agalactiae, which poses a significant risk of infection in new-born infants that may result in serious illness or death. -
Letheen Broth with Neutraliser and 1% Tween 80 is primarily intended for use in assessing the bactericidal activity of quaternary ammonium compounds and determining the phenol coefficient of cationic surfactants. It can also be used in environmental testing, particularly in areas subjected to surface disinfection. Lecithin and polysorbate 80 (Tween 80) inactivate surface disinfectants (lecithin neutralises quaternary ammonium compounds and Tween 80 neutralises phenols, formalin, hexachlorophene and in combination with the lecithin ethanol).

This is an egg-based medium for the isolation and presumptive identification of Mycobacterium spp., particularly Mycobacterium tuberculosis, from clinical samples. Based on the original formulation of Lowenstein that was subsequently modified by Jensen, the medium contains glycerol and egg which provide the required protein and fatty acids. The coagulation of the egg albumin during preparation also provides a solid surface for inoculation purposes. Malachite green is incorporated into the medium to inhibit contaminating organisms other than the mycobacteria that may still be present in the specimen after decontamination. Lowenstein Jensen Medium slopes should be inoculated with pre-treated specimens and incubated at 35-37°C for 8 weeks in 5-10% CO2. Container caps should be left loose for the first week of incubation to allow for circulation of the carbon dioxide as this will help to stimulate growth. Caps should then be tightened to prevent any dehydration of the medium

Maximum Recovery Diluent (Peptone/ Saline Diluent) An osmotically controlled solution for the preparations of suspensions of food samples and for use as a diluent in dilution techniques for bacterial enumeration. The presence of a low level peptone lessens the physiological shock normally experienced by bacterial cells when they are introduced to a diluent such as Ringers Solution. The level of peptone is such that multiplication of the organisms is not possible in the time in which the sample will be present in the diluent. -
This is a non-nutrient medium based on Page’s Amoeba Saline, a buffered salt solution, solidified with 1.5% Agar.

This is an aqueous solution of Sodium Hydroxide (2%) with Phenol Red Indicator suitable for use in the digestion of Sputum samples prior to culture of the samples for Mycobacterium spp. It is generally used in conjunction with Sputum Neutralising Buffer (BM1324).
