When clean plastic cartridges are not clean enough. 6 mL glass SPE cartridges can be packed with your choice of UCT sorbent using PTFE frits and individually sealed in certified Mylar for purity.

Enviro-Clean 500mg/6mL cartridge PSDVB w/Polyethylene frits. It is used with EPA Methods 526, 527, 528, 529 and 8330.

Select pH Buffer Pouches - UCT has developed a line of premeasured “ready-to-use” phosphate and acetate buffer pouches. These pouches contain the correct quantity of reagent to quickly and accurately prepare buffers at the correct pH and concentration to simplify solid-phase extraction methods.

Styre Screen® Extraction Columns contain an ultra clean, highly cross-linked styrene and divinylbenzene copolymer. The Styre Screen particles have an average particle size of 30 microns and a very high analyte capacity making them ideal for standard solid phase extraction applications. The increased analyte capacity means that less sorbent bed mass is needed which results in faster flow rates and less solvent use. Higher th…

XtrackT® columns are gravity-flow SPE columns that allow for extraction of acids, neutrals, bases in viscous samples such as equine urine, post-mortem blood and tissues, amniotic fluid, and meconium.

The Universal Vacuum Manifold system accommodates 24, 48 and 96 well plate configurations. This system includes a collection plate, extraction plate, manifold and vacuum gauge waste base for all wellplates.

Universal C18 - Enviro-Clean SPE Cartirdges Enviro-Clean® cartridges are designed for use by analysts that demand a clean, dependable and rugged product for low level environmental analyses. Universal C18 is used for the extraction of pesticides, herbicides and PCBs, etc.Part # ECUNIC18

These sorbents are composed of a silica backbone bonded with hydrocarbon chains. They are used to extract compounds, which exhibit non-polar or neutral characteristics, from complex matrices. The C18 phase is the most popular phase.  UCT offers a range of hydrocarbon chain lengths from C2 to C30. In addition, we offer isobutyl, tertbutyl, phenyl, and cyclohexyl bonded phases.

Compounds are retained on hydrophilic sorbents through polar interactions including hydrogen bonding, pi-pi or dipole-dipole interaction.  Compounds typically extracted on a hydrophilic column include analytes which have polar groups, including amines, hydroxyls and carbonyls. Elution is performed by strong polar solvents. For these types of extractions UCT offers various types of base silica, Florisil®, Alumina's, cyanopropy…

This sorbent is composed of a silica backbone bonded with a carbon chain terminated by a negatively or positively charged functional group. Ion exchange interactions occur between a sorbent that carries a charge and a compound of opposite charge. This electrostatic interaction is reversible by neutralizing the sorbent and /or analyte. Ion exchange bonds can also be disrupted by introduction of a “counter ion” to compete with…
