Buffered Peptone Water (BPW) (ISO) 5ltr Bag Pk 2

Buffered Peptone Water (BPW) (ISO) is a high-quality non-selective pre-enrichment medium designed for the recovery and resuscitation of stressed or damaged microorganisms prior to further microbiological testing. Supplied in convenient 5-litre bags, this ready-to-use medium is ideal for routine laboratory workflows requiring reliable sample preparation and enrichment.

Formulated in accordance with ISO recommendations, Buffered Peptone Water provides optimal conditions for the recovery of microorganisms that may have been exposed to environmental, processing or storage-related stress. The buffered formulation helps maintain a stable pH during incubation, supporting accurate and consistent microbiological analysis.

Suitable for food, beverage, environmental, pharmaceutical and research laboratories, BPW is widely used during pathogen testing and quality control procedures. The convenient 5-litre bag format reduces preparation time and supports efficient processing of larger sample volumes.
