The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support. Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed for selective and reliable HPLC applications. This exceptionally stable C1 phase features our least-retentive reversed-phase hydrocarbon packing. Stationary Phase Category: trimethylsilane (L13) Ligan…

Certified reference materials (CRMs) manufactured and QC tested in  ISO-accredited labs  satisfy your ISO requirements.

Whether you need to replace system tubing as part of your troubleshooting or want to reduce the dwell volume of your system as you move to narrower columns, Restek has the quality tubing in the lengths and IDs you need. Each ID is color-coded, so it is easy to identify and replace correctly. Tubing is precision cut, resulting in clean, square-cut ends without ovality.

Extend column lifetime. Excellent inertness—obtain lower detection limits for active compounds. Sharper chromatographic peaks by utilizing retention gap technology. Maximum temperature: 360 °C.

3-IN-1 TECHNOLOGY with Rxi® columns: • Highest Inertness • Lowest Bleed • Exceptional ReproducibilityRxi® columns are more stable at high temperatures than any other manufacturer’s column, resulting in higher system sensitivity. This low-bleed characteristic is the result of superior stabilization achieved by optimizing polymer cross-linking and surface deactivation technologies. Benefits of using ultra-low bleed Rxi® column…

TSKgel Amide-80 and TSKgel NH2-100 HILIC columns from Tosoh Bioscience are first class columns when it comes to separations of hydrophilic compounds like peptides, carbohydrates, polar natural substances, amino acids, oligonucleotides, organic polar acids and bases, even proteins.

HPLC column

Widely considered the premium columns for analyzing biopolymers by GFC, TSKgel G2000SWXL, 5 μm columns are an excellent choice for small proteins and peptide separations.

The TSKgel Alpha-4000 column is packed with rigid, porous polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP). This column is stable in a wide variety of organic solvents at concentrations up to 100%.

The TSKgel OligoDNA RP and TSKgel TMS-250 columns incorporate 5 μm or 10 μm spherical porous silica with 250Å pores to allow unhindered access by large oligonucleotides and proteins respectively.

TSKgel STAT columns were designed to increase throughput for high efficiency separations of biomolecules. The nonporous, hydrophilic base material provides superior performance at reduced analysis time.

mRNA sequencing (mRNA-seq) is a potent method for gene expression exploration, it unveils mRNA dynamics, different gene expression and regulatory mechanisms with precision.

ZIC®-HILIC HPLC columns for the separation of all classes of polar and hydrophilic compounds. What is HILIC? HILIC or Hydrophilic Interaction Liquid Chromatography is a straightforward chromatographic technique for separation of many types of polar and hydrophilic compounds. To put it simple one can say that HILIC is a normal-phase (NPLC) type of separation but uses reversed-phase (RPLC) type eluents. In HILIC one has: A c…

The base silica of Purospher® STAR columns is 99.999 % pure. Furthermore, meticulous care is given to quality control over all aspects of silica structure and chemistry. The excellent converge of the surface and the purity of the material ensures excellent peak symmetry for acidic, basic and even for chelating compounds. Accurate results with excellent peak shape for all types of analytes Outstanding resolution due…
