LabExact® Biologically inert mixtures of cellulose acetate and cellulose nitrate result in membranes with a smoother and more uniform surface than pure nitrocellulose filters. MCE is easier to handle and less likely to crack and fracture than traditional CN membranes.  Pure surface, no additional smoothing treatment or surfactants. Non-sterile version is bright white with an accurate pore structure and highly regulated density for accuracy.  Medium-fast flow rates with reproducible loading capacity.  Clean-edge processing ensures easy separation from stack and less curl.  Autoclavable. Use for clarification or sterilization of aqueous solutions, cytology, yeast and mold virus concentration, HPLC sample preparation of aqueous solutions, OSHA particle analysis, food and beverage microbiological QA/QC.  MCE is the standard for microbiological growth and colony counting methods.

Features

• Available in porosities of 0.22µm, 0.45µm and 0.80µm
• Non-sterile version is bright white, no grid pattern imprinted
• Pre-sterilized version using gamma irradiation and individually wrapped
• Accurate pore structure and highly regulated density for accuracy
• Medium-fast flow rates with reproducible loading capacities
• Clean-edge processing ensures easy separation from stack and less curl
• Autoclavable
• Mixed Cellulose Esters, hydrophilic, white color, black grid lines
• 0.22µm (sterilizing), 0.45µm (microbiological) and 0.8µm (clarification) retention version
• 6 mils thick, very close tolerance for consistent density and flow rates
• Water flow rate: 65mL/min/cm2 at 0.7 bar (10psi)
• Recovery: Average 90% as measured against pour plates
• The membrane will not alter the pH of incubation media beyond +/- 0.2 units
• Zero growth sterility (in gamma sterilized version)
• <2% extractables in boiling water
• Bacterial recovery testing has shown that grid lines neither enhance nor inhibit growth of bacteria.
• Recovery rates of total and fecal coliform bacteria indicate that there is no influence on bacterial growth and development due to chemical extractables.
• The sterilization process does not enhance or inhibit growth of bacteria in use
• Certified for the microbiological analysis of potable, waste, process, and natural waters in accordance with the Membrane Filter Technique referenced in Standard Methods for the Examination of Water and Wastewater., 20th edition, and the U.S. EPA's Microbiological Methods for Monitoring the Environment, 600/8-78-017.
• Ideal for isolation and enumeration of total and fecal coliforms, E. coli, fecal Streptococcus, fungi, and other heterotrophic bacteria.
• Suitable for air monitoring applications and meets NIOSH requirements for airborne metals and asbestos monitoring.

Applications:

• Clarification or sterilization of aqueous solutions
• The standard for microbiological growth and colony counting methods
• Cytology, yeast and mold virus concentration
• HPLC sample preparation of aqueous solutions
