Cellulose Nitrate membranes for sample pre-treatment, particle testing and chemotaxis.
Available in white, black or green, gridded (3.1 x 3.1 mm) or plain, sterile or non-sterile
They are ready-to use membranes and save preparatory time. Filter identification and lot number are printed on the box or on each individual envelope for the sterile versions.
Features:
· Hydrophilic membrane
· Made of Cellulose Nitrate. This material assures excellent retention and optimum colony growth
· Very uniform pore structure which ensures homogeneous distribution of the particles retained on the filter surface
· Various colours give the best contrast to the colonies which are to be counted
· Maximum temperature 130ºC
· Autoclavable
· Very high flow rate
Applications:
· Clarification and sterilisation of aqueous solutions
· Microbiological analysis and particle counts
· Particle size analysis
· Pre-filtration and clarification of samples prior to further analysis
· Removal of particles in suspensions to determine the degree of impurity
