Chromatic Coliform Agar ISO

Chromatic Coliform Agar ISO is a culture medium for enumerating coliform bacteria and E. coli in water samples with low bacterial background flora to replace Lactose TTC agar in accordance to the ISO 9308-1.

Chromatic Coliform Agar ISO contains enzymes that allow the simultaneous identification of several microorganisms in 24 hours, by defined colors of the colonies. Coliform bacteria and E. coli are potential pathogens found in samples with low background flora such as drinking water, disinfected pool water and finished water from drinking water treatment plants.

Catalog ref. 26490

packaging: 100 tubes x 3 mL

Catalog ref. 412450

packaging: 6 bottles x 200 mL

VTM is suitable for collection and preservation of clinical specimens containing viruses, including SARS-CoV-2 (COVID-19), Chlamydia spp., Mycoplasma spp. and Ureaplasma spp. The transport medium can be used with swabs and aspirates and is available in a plastic, screw cap tube (or a bulk format, 200 mL glass bottle). The transported microorganism remains viable for 48 hours at room or refrigerated temperature. VTM does not contain guanidium thiocyanate.

Features:

• 10-25°C storage temperature.

• Contains antimicrobial agents to minimize bacterial and fungal contamination, without affecting viruses, Chlamydia, Mycoplasma or Ureaplasma.

• A pH indicator (red phenol) indicates the medium integrity during the shelf life of the product.

• The tube stands upright on the laboratory bench thanks to the skirted, flat-bottom, while the conical shape allows an appropriate centrifugation of the sample.

• 16x100mm skirted tube with plastic red cap. Sterile. 100/pack

Biopharma applications

Wash solutions for sterility testing

Fluids A, D, and K are used for ensuring the sterility of injectables, non-injectables, liquid products, oils and ointments, antibiotic powders, sterile pathway devices and aerosols.

Fluid A is a washing buffer for general usage, compatible with the majority of samples. Fluid A is a liquid used for dissolving or diluting samples without affecting the viability of contaminating microorganisms. Its formula complies with the requirements of the harmonized method in the United States (USP), European (EP) and Japanese (JP) Pharmacopoeias for rising membranes during sterility testing by filtration. Fluid A is also available as gamma-irradiated double bagged products, particularly suitable for use in restricted areas like isolators and clean rooms.

Fluid D has the same formulation of Fluid A with the addition of Tween 80, is used in validation tests for bacteriostasis and fungistasis in articles containing lecithin, oil or a preservative, usually in the method controls of medical devices washing.

Fluid K is suitable for testing samples containing petrolatum, vaseline or oil solutions. It is commonly used for washing the production lines of medical devices and for samples difficult to filter or dissolve.

Fluid Thioglycollate Medium is a general purpose liquid enrichment medium used for sterility control of pharmaceutical products and for cultivation and isolation of fastidious anaerobic and aerobic microorganisms.

The composition is in accordance with the requirements of the Harmonized US, European and Japanese Pharmacopoeia as well as with ISO 7937 for isolation of Clostridium perfringens.
