Gridded cellulose nitrate filters

Gridded membranes made of mixed cellulose esters, sterile and individually packaged, for colony counting in routine microbiological quality control.

They are ready-to-use membranes and save preparation time.

The grid size is 3.1 x 3.1 mm.

Available in various colours to ensure the best contrast with the colonies.

Maximum working temperature: 130ºC. Autoclavable and with high flow rate.

Applications:

• Clarification and sterilisation of aqueous solutions
• Microbiological analysis and colony counting
• Particle size analysis
• Pre-filtration and clarification of samples before further analysis
• Removal of particles in suspensions to determine the degree of impurity.
