Tryptone Soya Agar, Contact Plate

Description

8320 – SGL supplies Tryptone Soya Agar (TSA) Contact Plates as ready-to-use prepared media for environmental monitoring and microbial recovery in routine microbiological quality control. They are suitable for pharmaceutical microbiology, environmental monitoring, cosmetics and personal-care testing. Where applicable, the product supports workflows described in USP <61> and <62>, Ph. Eur. 2.6.12 and 2.6.13, and the performance-testing principles of ISO 11133.

Tryptone Soya Agar (TSA), also known as casein soya bean digest agar, provides a non-selective, non-differential, general-purpose medium for cultivating and isolating fastidious and non-fastidious microorganisms. Its nutrient-rich formulation supports the growth of a wide range of bacteria, yeasts and moulds.

Tryptic digest of casein and peptic digest of soya bean meal supply complementary peptides and amino acids, creating a rich and balanced nutrient profile that supports microbial recovery and growth. Sodium chloride maintains the osmotic balance of the medium, while agar solidifies the medium and provides a stable surface for colony development.

Laboratories use contact plates to detect surface contamination in cleanrooms, healthcare facilities and other hygiene-critical environments. Users press the raised agar surface directly against the area under investigation, transferring microorganisms onto the medium. After the specified incubation period, users count the resulting colonies to assess the level of surface contamination.

SGL supplies these non-irradiated TSA contact plates in single-wrapped packaging for use in less-critical environments.

SGL manufactures and quality-controls the product to its internal specifications and in compliance with ISO 9001 (reference FM37824). A UKAS-accredited laboratory operating to ISO/IEC 17025 (accreditation number 4356) tests the product in accordance with ISO 11133. At the customer’s request, the laboratory can also perform additional specification testing.
