GVS Filter, Disk, PES, 0.1µm, 47mm, 100/PK 1214756

White nitrocellulose (NC) membrane discs, 142 mm diameter, 0.22 µm pore size, supplied 25 per pack, are mixed cellulose ester (MCE) filtration membranes designed for aqueous filtration, microbiological and particulate analysis, gravimetric analysis using ashing techniques, and sterility testing. The membranes are hydrophilic, unsupported nitrocellulose composed of cellulose nitrate and cellulose acetate polymers and are provided non-sterile for laboratory filtration applications.

Key Features:

• Membrane material: Nitrocellulose (mixed cellulose esters, MCE)
• Pore size: 0.22 µm
• Diameter: 142 mm
• Color/format: White disc, not gridded
• Pack quantity: 25 per pack
• Sterility: Non-sterile
• Autoclavable: Autoclavable at 121°C for 20 minutes

Advantages:

• Uniform microporous structure provides high flow rates and consistent flow and diffusion.
• Low residue on ashing (suitable for gravimetric analysis) and low extractables to preserve test integrity.
• Hydrophilic membrane wets readily for aqueous filtration and microbiological applications.
• Sufficient dimensional strength for handling and use in automated equipment without tearing.
