Oxoid™ Membrane Lauryl Sulphate Broth (500g) is a selective medium used in the membrane filtration method for the detection and enumeration of coliform organisms in water samples. It contains lauryl sulphate as a selective agent to inhibit non-coliform bacteria, while supporting the growth of Escherichia coli and other coliforms. This medium is widely used in the monitoring of drinking water, wastewater, and environmental samples.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Detection and enumeration of coliform bacteria in water using membrane filtration techniques
• Composition: Peptones and lactose to support coliform growth, with sodium lauryl sulphate to inhibit non-coliform organisms
• Preparation: Suspend 40g in 1 litre of distilled water, mix thoroughly, and sterilise by autoclaving at 121°C for 15 minutes
• Yield: Approximately 12.5 litres of prepared medium
• Storage: Store at 10–30°C, protected from moisture and light
• Compliance: Suitable for use in standard water quality testing procedures, including those specified in regulatory and environmental monitoring protocols
