Solid Phase Extraction (SPE)

Varian offers an unparalleled program of products and services for SPE. Whether you need packed bed or disc; polymer or silica; cartridge or 96-well plate, Varian has the solution for you.


The Captiva 0.2µm and 0.45µm depth filters plates are ideal to prepare precipitated protein samples for LC/MS analysis. Filtration is simple, versatile, and necessary to prevent clogging of expensive HPLC columns. The captiva 10µm and 20µm glass fiber filter plates are designed for clarifying highly particle-laden samples, such as freshly thawed plasma, preventing sample transfer problems due to pipette tip clogging

Purification Solutions

Isolation of compounds from synthesis mixtures presents a different set of challenges from analytical work. Varian offers complementary solutions to your purification needs.

Liquid/Liquid extraction

Varian Hydromatrix disposable liquid/liquid extraction cartridges provide a means of simplifying and speeding up multiple liquid/liquid extractions. All Hydromatrix filled cartridges contain a special grade of flux-calcined, high purity, inert diatomaceous earth packed into polypropylene tubes.

Trityl On Oligonucleotide Purification (TOP)

TOP meets the demand for simple, cost effective, high throughput purification of trityl-on oligoncleotides. TOP incorporates a unique 96-well plate with removable tubes, streamlined gravity flow protocol, polymeric resin and optimized binding solution. Varian's cutting edge BioSolutions technology delivers superior yields and purity for standard oligos up to 1 umol in scale and up to 50 mer in length.

Peptide and protein purification with OMIX®

Monolithic sorbent tip technology for dependable purification and superior results in Drug Discovery and Proteomix research.
OMIX® pipette tips for microextractions reliably purify and enrich femtomole to micromole levels of small molecule drugs, peptides and proteins prior to MALDI-TOF or LC/MS.
