GVS Filter, Disk, PTFE, Laminated, 0.22µm, 142mm, 25/PK 1215489

GVS Nitrocellulose (NC) MicronSep/MCE filter discs are hydrophilic membrane filters designed for filtration of aqueous solutions and microbiological and particulate analysis. These 47 mm, 0.45 µm white discs (pack of 100) provide rapid flow and high throughput for clarification, sterility testing, gravimetric/ashing analysis and industrial hygiene applications. The membranes are composed of a mixture of cellulose nitrate and cellulose acetate polymers and are intended for laboratory filtration use.

Key Features:

• Membrane material: Nitrocellulose / Mixed Cellulose Esters (MCE)
• Pore size: 0.45 µm
• Diameter: 47 mm
• Color: White; Pack quantity: 100 per pack
• Hydrophilic, unsupported membrane composed of cellulose nitrate and cellulose acetate
• Autoclavable at 121°C for 20 minutes
• Extractables: <4% (wetting agent present)

Advantages:

• High flow rate and high throughput due to a uniform microporous structure
• Consistent flow and diffusion rates for dependable analytical and microbiological results
• Hydrophilic surface and low extractables that minimize interference with aqueous analyses
• Autoclavability supports decontamination and reuse of validated laboratory workflows
