LabExact® Mixed Cellulose Ester (MCE) membranes are sterile and biologically inert mixtures of cellulose acetate and cellulose nitrate which results in membranes with a smoother and more uniform surface than pure nitrocellulose.

• Easy to handle, less cracking and fracturing than traditional cellulose nitrate membranes
• Pure surface with no additional smoothing treatment or surfactants
• Suitable for air monitoring applications
• Meets NIOSH requirements for airborne metals and asbestos monitoring
