Vacuum manifolds speed up the processing of SPE and filtration steps by drawing liquid through the plate into a waste or collection plate below.
Microlute™ Supported Liquid Extraction (SLE) is a method of separation based on liquid-liquid extraction, but with one phase immobilised onto an inert support, in this case, diatomaceous earth (DE). This has the advantage of eliminating costly and fragile glassware while allowing simple laboratory automation in 96-well plate format. SLE-DE has been shown to successfully remove phospholipids from biological samples such as serum, plasma and urine where it can cause ion suppression in LC/MS analysis. The Porvair Sciences SLE-DE plates are designed for the quick and cost-effective clean-up of biological materials prior to LC/MS analysis and work in harmony with our vacuum manifolds and deep-well collection plates.
