Ideal for particulate removal, especially when sample recovery is a concern

• Rapid processing of samples. Centrifugal devices are simple to use and save on sample preparation time. Spin multiple samples at once!
• Universal membrane filter. The GH Polypro hydrophilic polypropylene membrane is ideal for aqueous solutions and offers maximum chemical compatibility for aggressive solvents.
• 96.5% protein recovery. GH Polypro membrane is a low protein binding membrane. It removes unwanted particulate from samples with high recovery of critical proteins.
• Low extractables. Our HPLC-grade centrifugal devices are certified to be low in UV extractables.
• Low hold-up volume (< 5 µL) makes these devices ideal for expensive samples.
• High g-force ratings. Can be spun at 14,000 x g assuring rapid sample processing.
• Minimizes membrane clogging. G-force impacts the membrane at an angle, sweeping accumulated materials from the surface.
• Leak-free operation. Unique sealing technology assures leak-free operation without the use of O-rings or adhesives that can add extractables.
• Constructed of low binding polypropylene.
• Fits standard centrifuge rotors that accept 1.5 mL tubes.

• Sample preparation (particulate removal prior to sample analysis - HPLC, IC, GC).
• Removal of precipitates (metals, polymers, or crystals).
• Applications requiring maximum filtrate recovery from limited sample volumes.
• Isolation of DNA from agarose gel slices.
• Removal of cells from media prior to analysis.
• Separate oligonucleotides and RNA from acrylamide gels.
