Two ways in
Pick by the job, or pick by the chemistry.
BioSPE® is organised around what you are trying to do, clean peptides before LC-MS means PurePep, and you need not know which sorbent is inside. AttractSPE® is organised around the sorbent, for method developers who already know they need wide-pore C18 or a weak cation exchanger. Each card holds the formats, grades and pack sizes of that family: choose a format, then a grade and pack, and add it to your quote.
Formats
One chemistry, eight formats
Tips (10 µL, 200 µL, 1 mL), µSpin, spin columns up to 50 mL, 1 to 6 mL cartridges, 96-well plates and 384-well microelution plates, so a bench method scales to cohort size without changing sorbent.
Grades
Standard, High and Single-cell
BioSPE® products come in Standard and High capacity; PurePep adds a single-cell grade. AttractSPE® devices are graded T0-T3 by sorbent bed size.
Disk beds
Membrane disks, not loose beds
Sorbent-loaded disks keep dead volume low and flow even, the property that matters most at the 10 µL tip scale.

Applications
One sorbent family, many jobs.
01
Desalting before LC-MS
PurePep tips, spins and plates remove salts, buffers and detergent traces from digests so that DIA and DDA runs start clean.
DIA vs DDA 02Deep proteomes by fractionation
PepFrac basic-pH reversed-phase fractionation extends single-shot depth when a study needs more than one injection per sample.
Proteomics services 03Single-cell and low-input
10 µL single-cell grade tips keep dead volume and surface loss to a minimum where every femtomole matters.
Single-cell guide 04Intact protein and biologics
PureProt and wide-pore C4/C8 chemistries clean up intact proteins before intact-mass or peptide-mapping work.
Biologics 05Glycoproteomics
GlycaClean purifies released glycans and glycopeptides ahead of HILIC or reversed-phase analysis.
PTM analysis 06Metabolomics clean-up
PureOmics extracts and purifies metabolites from plasma, urine and culture medium before LC-MS.
Metabolomics 07SP3 and bead-based workflows
BeadRem plates strip residual magnetic beads from SP3 and immunoprecipitation eluates before injection.
