Method
The liquid is filtered through a membrane. The microorganisms collect on the membrane surface. The filter is incubated on a nutrient medium and the individual colonies can then be evaluated. The method is also suitable for large sample volumes and low microorganism counts.

Reliability
The quality control and product design of our membrane filters are strictly controlled and offer users significant advantages.

Test parameters
All membranes used for microbiological quality control are tested systematically in order to ensure the same high quality from batch to batch. Parameters tested are bubble point, flow rate, bacterial retention, recovery rate, and sterility.

MicroPlus Membranes

Features and benefits
ㆍSpecial membrane filters made from cellulose nitrate developed for microbiological quality control
ㆍHigh mechanical strength
ㆍHigh flow rate
ㆍSterile, individually packed
ㆍAll membrane filters have a high-contrast grid (3.1 mm)
ㆍType STL in dispenser boxes with 100 numbered membrane filters for easy removal and safe handling with the Membrane-Butler (supplied in 4 boxes each with 100 membrane filters)

ME Membranes

Features and benefits
ㆍMade from mixed cellulose esters
ㆍEconomical
ㆍSpecifically for aqueous solutions
ㆍHydrophilic
ㆍFor use up to 125ºC
ㆍSterile, individually packed
ㆍAll membrane filters have a high-contrast grid (3.1 mm)
ㆍType STL in dispenser boxes with 100 numbered membrane filters for easy removal and safe handling with the Membrane-Butler (supplied in 4 boxes each with 100 membrane filters)
