• Sterile, individually packed
• All membrane filters have a high contrast grid (3,1 mm)
• Type STL in dispenser boxes with 100 numbered membrane filters for easy removal and safe handling with the Membrane-Butler

MicroPlus membranes with cellulose nitrate filters have high mechanical strength and high flow rate.

ME membranes with hydrophilic mixed cellulose ester can be used specifically for aqueous solutions. For use up to 125 °C

All Whatman brand membranes used for microbiological quality control are tested systematically in order to ensure the same high quality from batch to batch. Bacterial retention, bubble point, flow rate, recovery rate, and sterility are all tested.
