Ultra-high molecular weight polyethylene (UHMWPE); increased resistance to abrasion; best for buffers.

We manufacture our frits from fine, chromatographic-grade 316 stainless steel, and we offer sizes to fit most column and pore sizes. To choose the correct frit, check its pore size compatibility with the particle size of the packing in the column. If the packing has a smaller particle size than the…

A 316 stainless steel tip with a Tefzel collar seals to a corrosion-resistant 316 stainless steel filter element. The slip-on filter easily attaches to the pump inlet line, without the use of wrenches. The universal 1/8" OD tip accommodates standard PTFE tubing inner diameters. The cylindrical…

Fluid resistor technology eliminates adjustments to capillary tubing for optimizing split ratio. Wide range of interchangeable resistors available. Fixed Flow Splitters for HPLC & LC-MS Split ratio not affected by changes in viscosity or pressure High operating pressure limit:…

Securely holds 1/16" or 1/8" tubing in beaker, flask, or bottle up to 4 mm thick.

Protect contents and prevent carryover with pre-slit cap mats Chemically resistant, silicone mats are excellent for compound storage to -80°C Pre-slit mats pierceable by autosampler needle, pipette tip, or probe Universal mat for sealing 0.45, 1.3, and 2.0 mL plates

Ten compartments, plus a wiper dispenser* Lightweight, movable, wall-mountable *Please note: Accessories and supplies in photograph are not included.

An efficient cross-flow shearing mechanism and interchangeable cartridges produce vortex shear mixing over a wide range of flows. Stainless steel or PEEK. Reduced baseline noise Increased sensitivity Improved gradient accuracy for more reproducible results Increased reaction…

The ValvTool is a time-saving device that provides easy access to many hard-to-reach Rheodyne or Valco valves. For 1/4" nuts.

Hand-tight fitting style achieves effortless HPLC seals—no tools needed for a 8,700+ psi seal Both hand-tight and hex-head styles wrench-tighten for reliable UHPLC use up to 20,000+ psi! Patented ferrule can be installed repeatedly without compromising high-pressure seal Hybrid…

Our valves have low internal volumes and are rated to 15,000 psi (103,421 kPa). They feature a two-piece stem assembly in which the rotating upper shank is coupled through a ball joint to a static lower stem. Only finger-tight torque is required to make the seal.

Piston seals wear out over time and Restek is your best option for economical replacements. Choose our graphite-filled PTFE seals, which are best for organic solvents.

Double ball and seat check valve. Compatible with Waters ACQUITY H-Class Bio QSM, ACQUITY M-Class µBSM, and ACQUITY M-Class ASM Systems.

Cost-effective protection for UHPLC systems Reliable way to extend column lifetime Universal fit—connects easily to any brand column Leak-tight to 15,000 psi (1,034 bar) 0.5 µm or 0.2 µm titanium frit in a stainless steel body with PEEK ferrule

Use on the side of instrument, hood, or file cabinet Include: 3M double-stick, removable tape mounts

Universal PEEK connectors allow easy installation of all 1/16" tubing, including stainless steel, up to 5,000 psi.

A Trident in-line guard cartridge holder can be used with almost any HPLC column by connecting it with a short piece of 1/16" tubing, appropriate nuts and ferrules, or finger-tight fittings. The system can be used with Restek columns, or with columns from other manufacturers. Holders are…
