Biotage® Universal Phase Separator are currently unavailable and can not be ordered. We apologize for the inconvenience.
ISOLUTE Phase Separators have been designed to rapidly separate chlorinated solvents from aqueous phases, under gravity.
The phase separators are available in a comprehensive range of column sizes (3, 6, 15, 25, 70 and 150 mL) and in convenient packages of 25-100 (depending on size).
Unlike other phase separation devices, no vacuum or positive pressure is required – the separation is achieved under gravity. The phase separator is impervious to aqueous solvents, but allows the passage of water immiscible solvents of a higher density than water.
There are no moving parts, nothing to prime, its all achieved by hydrophobic/hydrophilic interactions, the cartridges arrive ready to use and are compatible with a wide variety of solvents.
How Phase Separators Work
The compound is partitioned, due to differences in solubility, between two immiscible liquids. The lower organic phase can pass through the frit, the upper aqueous phase physically cannot. There is an automatic cut-off at the organic/aqueous interface.
Reasons customers choose Phase Separators
Phase Separators comply with 6 of the key principles of Green Chemistry - prevent excess lab waste, maximize atom economy, facilitate use of safer chemicals and products, and utilize less hazardous chemical synthesis, increase energy efficiency, and minimize the potential for accidents.
The life-time cost of a glass sep-funnel can average around $150. Also, itis easy to use more solvent than necessary using a glass funnel, as it is tempting to over-extract. All this means the cost of solvent (approx 2-3 washes, of 50-100mL, over 20 uses) is higher than it needs to be when using a glass funnel. Compare this to phase separators. They're economic, easy to use, fast and disposable, so no contamination issues either.
Save time, reduce solvent, Phase Separator tubes are easier to store than glass sep funnels, and are geometrically designed to line up on a FlashVac or rack system, thus enabling the chemist to carry out multiple extractions in parallel. After-use, there is no need to waste valuable time and detergent / solvent, by re-washing, the disposable format allows for a very fast turn around and cycle time for further exactions.
Phase Separators are designed to stand alone, working by unattended operation. Just open the lower tap (optional accessory) and walk away, the cut off is automatic.
