Optimize Technologies ITB™ PTFE Piston Seal, (Microbore Type) Bischoff 2200, Anspec SM909, Alcott Micromeritics760, 10pk
Optimize Piston Seals are the longest lasting seals on the market. Machined from either of two proprietary polymer blends, UHMW-PE or ITB, Optimize Seals provide the ultimate in high pressure sealing capacity. For mostly aqueous buffered mobile phases, PTFE-based Improved PTFE Blend (ITB) seals are a superior choice for applications with elevated temperatures, high organic content, or when the broadest possible solvent compatibility is required. ITB™ seals tend to be softer than those made from UHMW-PE, making them more forgiving at high pressures where piston side-loading or misalignment may occur. This softer nature also leads to more shedding, but the ITB™ proprietary blend is designed to shed particles that are large enough to be caught at the surface of a standard 2µm frit, not embed within it.
Trajan Scientific CPLRY BP20-30MX0.25MMX1UM
SGE BP20 (WAX) Capillary Columns, Diameter Inner: 0.25 mm, Film Thickness: 1 um, Length: 30 m, For Use With: GC, Fragrance Analysis, Aldehydes Analysis, Ketones, Packing Material: SGE BP20 (Wax), Particle Size: 1 um, Stationary Phase: Polyethylene Glycol, Polarity: Polar
Perkin Elmer US LLC 15% Graphite 85% Vespel Ferrule
Provide a continuous leak-free connection and are perfect for connecting your column to a GC/MS. The SilTite metal ferrule and nut are manufactured from the same material and therefore expand and contract at the same rate, eliminating the need to retighten even after temperature cycling. The base of the SilTite ferrule forms a perfect seal with the MS interface, ensuring a leak-free connection. SilTite metal ferrules have a temperature limit well above the temperature capacity of the injector, MS interface or GC oven.
Trajan Scientific CPLRY 15QC2.5/BPX50-0.25
SGE BPX50 Capillary Column, Film Thickness: 0.25 um, Particle Size: 0.25 um, Length: 49 ft., 15 m, Diameter Inner: 0.25 mm, For Use With: Drug Screening, GC, Steroids Analysis, Herbicides Analysis, Packing Material: SGE BPX50, Stationary Phase: 50% Phenyl Polysilphenylene Siloxane
Optimize Technologies OPTI-MAX Inlet Cartridge Check Valve, 3/16" Ceramic Ball & Seat, Stainless Steel Cartridge, All Beckman
Opti-Max™ Cartridge Check Valves are designed to offer maximum performance and ease of use. From the sharp, consistent threads on OPTI-MAX™ custom housings, to the exacting standards used to match ball/seat sets in OPTI-MAX™ cartridges, every aspect of design and manufacturing reflects an unavoidable fact: when it comes to reliable check valve operation, quality and precision make a big difference. OPTI-MAX™ check valves offer many advantages over OEM check valve systems, and are better designed, better made and more reliable than any other after-market check valve product. Additionally, OPTI-MAX™ Free-Turn™ housings can be removed with the tubing still attached, accelerating check valve maintenance while reducing fitting wear.
Optimize Technologies Sapphire Plunger, Shimadzu LC-10AS, 6AD, 7A
Pistons are, by design, a consumable part of the HPLC pump and should be replaced on a regular preventative maintenance schedule. To maintain peak performance and avoid unplanned downtime, sapphire pistons require inspection every six months with yearly or as-needed replacement. Optimize sapphire pistons offer optimal concentricity and resistance to wear. Each sapphire rod is specifically cut in relation to the grain of the crystal lattice, yielding maximal resistance to breakage and superior wear characteristics. Attachment of the rod to the piston ferrule is performed through a proprietary process ensuring concentricity. This is an important, often overlooked procedure parameter that has a direct effect on seal lifetime. This item is equivalent to OEM part number 228-17019-93.

Optimize Technologies EXP2 Stem Trap Kit, 2.6µL, 2.7µm HALO, HILIC
A standard EXP™2 Stem Trap Kit includes (1) EXP™2 Stem Holder and (3) packed stems. Specialized features, patented technology, precision engineering and state-of-the-art manufacturing make the new EXP2 Stem Trap an unbeatable choice for ultra high-pressure trapping applications. Its slim architecture allows it to easily fit into crowded instrument compartments or to connect directly to tightly-spaced injection ports. When tightened by hand, the EXP2 Stem Trap seals to 8,700+ psi. Additionally, the product can be wrench tightened to 20,000+ psi (1,400+ bar). The unique packed floating stem installs directly into any 10-32 port and automatically adjusts to provide a perfect ZDV connection. The replacement stems are low volume/ low-dispersion, intended for many repeat uses and is available with various bed volume and custom packing options. This product is recommended for nano flow applications.
