DryDisk^® Separation Membrane
with Gore-Tex Process Filtration Media

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 extractions, DryDisk® Separation Membranes eliminate the problems inherent with chemical drying such as; retention of water-soluble compounds, over-saturation, caking, oven drying, messy waste removal, 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 Gore-Tex^® membrane has an infinite capacity for residual water and 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		Unlimited capacity for water
	Increased sample throughput		Works on emulsions
	Repeatability		Less lab waste and no oven drying

DryDisk® Separation Membrane NEW
50 mL Disposable Barrel

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 sulphate drying technique. The barrel is made from high purity HDPE (high density polyethylene) and has a GORE-TEX® PTFE membrane embedded inside. The membrane is supported by an inert polymeric laminate for maximum mechanical integrity.

Placement of the DryDisk® Separation Membrane 50 mL Barrel on the DryVap® Concentrator System

	DryDisk® integrated with the barrel, no assembly required.
	Simply place the barrel in the manifold, add the sample and run.
	Removes residual water from smaller volume, non-polar solvent extracts.
	Replaces conventional sodium sulfate drying.
	Compatible with 3rd party SPE vacuum manifolds.
	Discard the barrel after use, no messy clean-up.

The DryDisk® Separation Membrane 50 mL Barrel offers the maximum in speed and convenience for drying smaller volume extracts as there is no assembly required. The DryDisk® Separation Membrane 50 mL Barrel is useful for removing water from methylene chloride extracts, methylene chloride/acetone mixtures, alkane based solvents, toluene and ethyl acetate. DryDisk® Separation Membrane 50 mL Barrel is not designed to remove water from polar solvents such as acetone, methanol, or acetonitrile. The DryDisk® Separation Membrane 50 mL Barrel may be used with the DryVap® Concentrator System, or with 3rd Party SPE Manifolds.
