GVS Filter Paper, Disk, 110mm, Ashless-Fast, Grade 41, 100/PK FP110DFA41QANC01

GVS centrifugal filter for 50 ml conical tubes is a laboratory ultrafiltration device for centrifugal concentration and purification of biological samples. It features a 30KD molecular weight cut-off membrane and is supplied in white housings. The unit is intended to concentrate and clarify aqueous biological samples by molecular-size separation and is packaged as 8 pieces per box with 12 boxes per case.

Key Features:

• Conical tube volume: 50 ml
• Molecular Weight Cut-Off (MWCO): 30 KD
• Filter material: ABS (Acrylonitrile-Butadiene-Styrene) housing
• Final concentrate volume: 200 µl
• Active membrane area: 5.48 cm²
• Maximum centrifugal force: Swinging bucket rotor 3,000 x g; Fixed angle rotor 4,000 x g
• Packaging: 8 pieces per box; 12 boxes per case

Advantages:

• Enables centrifugal concentration and purification of biological samples for downstream analysis.
• 30 KD MWCO membrane provides molecular-size based separation suitable for retaining target macromolecules while removing smaller contaminants.
• Robust ABS housing and defined maximum g ratings allow use in both swinging-bucket and fixed-angle rotors.
• Consistent final concentrate volume (≈200 µl) and defined active membrane area support reproducible sample processing.
