L C A C C E S S O R I E S Pump Accessories PEEK Mixing Tee • Better mixing than a conventional tee • Inert, metal-free construction • Ideal for high-pressure gradient mixing Better mixing is the result 5616 of the turbulence generated by the angled ports and the flow through a PAT (PEEK alloyed with TFE) filter element. Solvent streams mix more thoroughly than with a conventional tee. This reduces baseline noise and improves high pressure gradient mixing or post-column reactions. Solvents contact PEEK and the PAT filter, providing a biocompatible, inert, and metal-free flow path. This tee has a 2.5µL internal volume, a pressure limit of 6000psig, and comes with fittings and ferrules. Toroid Mixer • High efficiency mixer for preparative chromatography • Precise and reliable © Copyright 2004 Alltech Associates, Inc. PEEK MIXING TEE DESCRIPTION QTY. PART NO. PRICE Mixing Tee with Fittings ea 32157 Replacement Fittings 5 35752 Replacement Ferrules 5 35730 The unique design of the 4708 Toroid Mixer extends the mixing characteristics of a pulse dampener in higher flow rate applications. High efficiency mixing yields reproducible quantitation, better reproducibility of retention times, and reduced baseline noise due to uniform solvent composition. Featuring a clean-swept mixing chamber, the Toroid Mixer has no motors or moving parts. Toroid Mixer Specifications Internal Volume: 5mL Flow Range: 10 to 200mL/min Maximum Pressure: 6,000psig Flow Path: PEEK TOROID MIXER DESCRIPTION PART NO. PRICE Toroid Mixer, Biocompatible 060143 1024 ASI Static Mixer • Interchangeable mixer cartridges • Selectable volume* • Suitable for analytical and micro LC flow rates ASI HyperShear Static Mixers use a highly efficient liquid-liquid shearing interface which induces vortex mixing over a wide flow rate range. The versatile cartridge design is available as an in-line, binary, or ternary inlet housing. Analytical volume housings accept 350 or 500µL mixer cartridges. Low volume housings accept 50, 150 or 250µL mixer cartridges. And Micro volume housings accept 2, 5, 10 or 25µL mixer cartridges. All are rated to 5000psig.

Valves L C A C C E S S O R I E S Rheodyne ® MX Semi- Automatic Analytical Injectors • Electronic manual valves eliminate actuation inconsistencies • Simple to install without special software • Capable of full automation for unattended operation Rheodyne ® Model 7725 and 9725 Analytical Injectors • “Make-Before-Break” (MBB ) switching for uninterrupted flow • Wider port angles provide improved fitting access • Position sensing switch option 6514 MX Semi-Automatic Injection Valves can be operated either by push button, allowing them to function as a “manual” valve, or by contact closure for complete remote control. With its specially designed needle port, sample is loaded directly into the valve. The push of a button injects your sample without the inconsistencies of manually turning a handle. Unlike any other manual valve, the MX Semi-Automatic Injector is also capable of complete automation. By connecting the valve to a single contact closure, a sample can be loaded during system equilibration and injected unattended when the system is ready. No more waiting for the LC ready signal, just load the sample and forget it. MX Semi-Automatic Sample Injector Specifications Maximum Pressure: 5000psig (345 bar) Flow Passages: 0.25mm (.010") diameter Power Requirements: 100-240 VAC, 50/60 Hz CE Mark: Yes Remote Control: One-Line contact closure (open = valve position 1, closed = valve position 2) Operating Temperature: 4–40°C Dimensions: 10.2cm H x 7.6cm W x 12.7cm D MX ANALYTICAL SEMI-AUTOMATIC SAMPLE INJECTORS DESCRIPTION VERSION PART NO. PRICE MX Injector SS 447925 MX Injector PEEK 449925 The 7725 and 7725i are capable of injecting volumes from 1µL to 5mL with high precision. The 7725i features a built-in position-sensing switch, providing the chromatograph with a reproducible start signal. The 9725, 9725i are biocompatible versions. Wetted materials are PEEK and Tefzel ® , making them ideal for applications requiring a metal-free flow path. Also available is the Suction Needle Adapter which eliminates exposure of the sample to the metal of a syringe needle. These valves have a “Make-Before-Break” system, which prevents flow interruptions while switching. This protects any columns, detectors, or pumps which might be affected by flow or pressure fluctuations. A 20µL PEEK sample loop is included with each valve.
