A general-purpose medium for the cultivation of organisms that are less fastidious in their nutritional requirements. -
Based on Nutrient Broth with an additional 2.5% Sodium Chloride this medium is suitable for use in the investigation of outbreaks involving Staphylococcus aureus especially MRSA. The additional Sodium Chloride inhibits most other organisms allowing the staphylococci to multiply freely even if present in small numbers. The medium is generally used as an enrichment medium in conjunction with subculture onto selective solid media as described in PHE SMI B29 issue No.6. -
Based on Nutrient Broth with an additional 6.0% Sodium Chloride (Total Sodium Chloride content = 6.5%) this medium is suitable for use in the investigation of outbreaks involving Staphylococcus aureus including MRSA. The additional Sodium Chloride inhibits most other organisms allowing the staphylococci to multiply freely even if present in small numbers. The medium is generally used as an enrichment medium in conjunction with subculture onto selective solid media. -
Based on Nutrient Broth with an additional 6.5% Sodium Chloride (Total Sodium Chloride content = 7%) this medium is suitable for use in the investigation of outbreaks involving Staphylococcus aureus including MRSA. The additional Sodium Chloride inhibits most other organisms allowing the staphylococci to multiply freely even if present in small numbers. The medium is generally used as an enrichment medium in conjunction with subculture onto selective solid media. -
This is an aqueous solution of Oxalic acid (3%) suitable for use in the digestion and neutralisation of Sputum that may be contaminated with Pseudomonas like organisms prior to culture. -
This is an aqueous solution of Oxalic acid (5%) suitable for use in the digestion and neutralisation of Sputum that may be contaminated with Pseudomonas like organisms prior to culture. -
A general-purpose diluent for the preparation of test samples according to ISO/DIS 6887-5. -
A standard biochemical reagent suitable for a variety of uses, primarily the preparation of serial dilutions. -
Based on the formulation of Dulbecco Solution ‘A’ this balanced salt solution is intended for use primarily in Tissue Culture techniques. It can be used either on its own or with the addition of Calcium and Magnesium salts (Dulbecco Solution B). -
Based on the formulation of Dulbecco Solution ‘A’ this balanced salt solution with added Tween is intended for use primarily in Tissue Culture techniques. It can be used either on its own or with the addition of Calcium and Magnesium salts (Dulbecco Solution B). -
This buffer is intended primarily for use as a neutralising agent following treatment with alkaline compounds during the decontamination and homogenisation process of Sputum specimens prior to inoculation onto appropriate culture media for the isolation of Mycobacterium spp. -
An osmotically controlled solution for the preparation of suspensions of food samples and for use as a diluent in dilution techniques for bacterial enumeration. The solution may also be used in the sampling of food production apparatus by the rinse and swab method. -
An osmotically controlled solution for the preparation of suspensions of food samples and for use as a diluent in dilution techniques for bacterial enumeration. The solution may also be used in the sampling of food production apparatus by the rinse and swab method. -
This is a variation on the common osmotically controlled Ringers solution, where glass beads have been added to enhance macerations in the preparation of suspensions of samples and for use as a diluent in dilution techniques for bacterial enumeration. The solution may also be used in the sampling of food production apparatus by the rinse and swab method. -
A long established selective medium for the isolation of yeasts and fungi suitable for use in all areas of Mycology. The low pH (5.6) of the medium inhibits most bacteria and spore structures and pigmentation of fungi are generally well developed on this medium. -
Sterile Saline (0.45%) is suitable for use in preparation of food samples and/or as a rinse fluid during examination of equipment etc. prior to culture. It can also be used as a general purpose diluent in many areas of the laboratory.
-
Sterile Isotonic Saline suitable for use in preparation of food samples and/or as a rinse during examination of equipment etc. prior to culture. It can also be used as a general purpose diluent in many areas of the laboratory. -
This is a variation on sterile isotonic Saline which is suitable for use in preparation of food samples and/or as a rinse during examination of equipment etc. prior to culture. It can also be used as a general purpose diluent in many areas of the laboratory. The addition of glass beads will allow dense material to be broken down and aid the isolation of any bacteria that may be present in “clumps”. This particular product is double wrapped and terminally sterilised by Ethylene oxide. -
Universal Isotonic Saline Solution. -
A medium for the selective enrichment of Salmonella spp from both clinical and food samples. It is a buffered Lactose Peptone Broth to which Sodium Biselenite is added as the selective agent. Subcultures should be made from the top 1/3 of the broth after not more than 24 hours incubation as after this time there is a loss of selectivity. -
This medium can be used as a screening method for the differentiation of Enterobacteriaceae based on the ability of some species to utilise citrate as a sole source of carbon. It is often used as a screening test for Klebsiella pneumoniae (Positive reaction) while Escherichia coli is negative. Other uses included distinguishing between species of citrate positive Salmonellae (e.g. Salmonella enteritidis) and those that are negative (e.g. Salmonella typhi and Salmonella paratyphi A). The medium is inoculated by stabbing the organism (in pure culture) into the medium. A positive result produces a change of colour from green to bright blue and a negative reaction leaves the colour unchanged. -
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). -
This is an aqueous solution of Sodium Hydroxide (4%) suitable for use in the digestion of Sputum samples prior to culture. It is generally used in conjunction with Sputum Neutralising Buffer (BM1325). -
