STL Membrane Circles

Membrane for microbiological quality control. Improved version of sterile, individually packed folded band (STL) of membranes to be compatible with most available membrane dispensers. STL membranes are widely used in food, beverage, pharmaceutical and cosmetic industries to determine microbial contaminants.
  • High mechanical strength means that the membranes will not rupture.
  • Sterile, individually packed, folded (STL) band of filters are housed in dispenser boxes with numbered membrane filters for easy removal and safe handling with a membrane dispenser.
  • Single sterile (ST) packed filters are also available.
  • Combination of high flow rate and membrane composition from standard mixed cellulose esters for faster processes.
  • Hydrophilic membranes are specifically made for aqueous solutions.
  • All membrane filters have a highcontrast grid which allows convenient counting of the microbial colonies.
  • Highest quality assurance and performance standards.
