Separations Products & Reviews

The vacuum assisted DigiFILTER assembly provides a quick and easy way to filter samples prior to analysis.  Increase lab productivity by filtering particulates from digested samples in a matter of seconds.

The 7200 Preconcentrator represents the next generation in GC and GCMS sample preparation systems for the analysis of vapor-phase volatile compounds.

Individually Packed, 100/pk Part Number: SFS-AR-1025

Flash gas chromatography electronic nose

For HPLC, Spectrophotometry and Applications requiring ACS grade solvent

SilcoSmooth Stainless Steel Separate permanent gases, including carbon monoxide and carbon dioxide, without cryogenic cooling. Rapid separations of permanent gas/light hydrocarbon mixtures. Excellent compatibility with most GC detectors—minimal bleed, minimal baseline rise. Preconditioned, less than 30 minutes to stabilize. Maximum temperature of 280 °C/300 °C.

By adding β or γ cyclodextrin to our bonded Rtx-1701 stationary phase, we greatly enhance overall utility and column lifetime for our chiral columns, compared to columns that have pure cyclodextrin stationary phases. Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and our columns continue to demonstrate stability after hundreds of temperature program cycles. What are ch…

low-polarity proprietary phase

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

Use with any standard male luer end SPE cartridges. Inert, PTFE sample guides reduce cross-contamination and carryover. Flexible sample collection rack will accommodate a variety of receiving vessels. Quick vacuum-release valve for better system control. Individual valves allow vacuum control for each cartridge, improving reproducibility.

UHP stainless steel regulators are the standard for ultra-high-purity and corrosion-resistant pressure regulation. They are more easily purged of atmospheric components compared to brass gas regulators, making them ideal for the most demanding applications. Stainless steel is especially useful in atmospheres of dry corrosive gases such as hydrogen. All regulators are rated to 3,000 psig (20,684 kPa) maximum inlet pressure.…

Vial-to-instrument compatibility is designated in instrument reference chart at https://www.restek.com/catalog/view/139 

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or "core-shell" particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times with existing HPLC and UHPLC instrumentation.  Stationary Phase Category: Proprietary Ligand Type: Proprietary Partic…

Thermo Scientific™ TraceGOLD TG-5SilMS GC Columns incorporate phenyl groups in the polymer backbone for improved thermal stability, reduced bleed and reduced susceptibility to oxidation.

The CombiFlash NextGen 300+ comes standard with all options installed. Flow rate range is from 1 to 300 mL/min at operating pressures up to 300 psi (20 bar). The system is fitted with a solid load injection valve that can be bypassed if you decide to perform a liquid injection.

TrueNano HPLC

Our classical silica TLC plates are based on a combination of our proven silica gel 60 and the addition of a unique polymeric binder resulting in a very adherent and hard surface that will not crack or blister and even allow writing with a pensil on the surface without risk to damage the layer.

500 g, cation exchange resin, sodium form, 1% crosslinkage, 50–100 dry mesh size, 300–1,180 µm wet bead size, ~3,500 MW limit

Measure trace bromate and other oxyhalides in drinking water, ground water, wastewater, and other diverse sample matrices with the Thermo Scientific™ Dionex™ IonPac™ AS23 carbonate eluent anion-exchange column.

Low-polarity phase; Crossbond diphenyl dimethyl polysiloxane.

Proprietary Crossbond diphenyl/dimethyl polysiloxane phase

The Ceres Nanosciences Nanotrap® Protein particles utilize affinity capture and size exclusion to attract and bind low abundance proteins, while excluding unwanted high abundance and high molecular weight interfering molecules.
