drdisk-mebranDry Disk Membran


DryDisk Separation Membranes offer a much more efficient means of drying solvents in organic extractions than sodium sulfate. Because it is a physical separation rather than a chemical process to remove residual water from organic solvent extracts, DryDisk Separation Membranes eliminate the problems inherent with chemical drying such as retention of water-soluble compounds, over-saturation, clogging, oven drying, messy waste removal, and inability to handle emulsions.

The labor required to dry extracted samples using DryDisk Separation Membranes is significantly less than that of the multi-step chemical process. Faster sample turn-around times lower laboratory costs while increasing overall productivity. The non-contaminating, hydrophobic PTFE membrane will not interfere with the adsorption of analytes, increasing your range of analyte testing with complete, consistent recoveries.


Advantages of DryDisk Separation Membrane over sodium sulfate drying:

  • Faster sample processing
  • Increased sample throughput
  • Repeatability
  • Unlimited capacity for water
  • Works on emulsions
  • Less lab waste and no oven drying



The new DryDisk Separation Membrane 50 mL Barrel is a disposable sample preparation device that provides a fast and simple approach for removing residual water from non-polar solvents. The DryDisk membrane replaces the conventional sodium sulfate drying technique. The barrel is made from high purity HDPE (high density polyethylene) and has a PTFE membrane embedded inside. The membrane is supported by an inert polymeric laminate for maximum mechanical integrity.
