Rt-βDEXse Columns (fused silica)

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…

Dual-Stage Ultra-High Purity Stainless Steel Gas Regulators

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.…

Raptor EtG/EtS LC Column

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…
