GVS Oil-Free Piston Vacuum Pump V400 100mbar; Max. Flow Rate: 34 L/min 220V/50Hz UK Plug, 1/PK OIFPUMPV400L34UA

GVS PVDF transfer membrane sheets are naturally hydrophobic, unsupported PVDF membranes designed for protein transfer and retention during electrophoretic applications. They provide high binding capacity and low background for improved signal-to-noise in assays and are intended for use in Western blots, immunoblotting and solid-phase assays. The product is supplied as 70 x 84 mm sheets with 0.22 µm pore size in packs of 10 for laboratory blotting and analytical workflows.

Key Features:

• Membrane material: PVDF (polyvinylidene difluoride)
• Pore size: 0.22 µm
• Sheet dimension: 70 x 84 mm
• Box quantity: 10 sheets per pack
• Hydrophobic: Yes
• Thickness: 0.14–0.25 mm

Advantages:

• High binding capacity prevents protein passage through the membrane, improving retention during transfer
• Low background provides an excellent signal-to-noise ratio for clearer detection
• Exceptional tensile strength resists cracking, tearing or curling during handling and processing
• Broad chemical compatibility allows use with common stains (e.g., Amido Black, Coomassie Blue, Ponceau-S) and tolerates high methanol concentrations without distortion
