Idex Micro-Metering and Micro-Splitter Valves: Needle Valves 

Description

Both metering and splitter valves available

• Chemically compatible construction
• Ship complete with fittings

• Can reduce outgoing flow to as low as 3.5μL per minute
• Needle valves are perfect for use with peristaltic pump fluid-transfer applications, mass spectrometry, and fraction collection
• Can also be used to regulate gas flow in helium sparging lines and as a flow-dependent variable back-pressure regulator
• Material: PEEK™, Black
• O.D. tubing: 1/8 in.
• Thru-hole: 0.020 in. (0.50mm)
• Internal volume: 7.7μL (max., with valve fully open)
• Includes: (2) XP-330
• Flow rates as low as 3.5μL/min. (at 1mL/min. incoming flow rate w/ room-temperature water)
• 1/4-28 flat-bottom port configuration
• Flow path materials are PEEK™ polymer and PTFE

• Accurately split and control a low-flow stream from a single incoming supply
• Biocompatible medium pressure micro-splitter valves (05-700-383, -384) are perfect for LC-MS and other multi-detector systems, fraction collectors and post column reactions
• Ideal placement of these valves is on effluent side of detector flow cell, at maximum pressure of 800 psi (55 bar)
• Choose between 1/4-28 and 10-32 threaded versions

• Designed to operate under pressures up to 4,000 psi (276 bar)
• Well suited for running two analytical devices in parallel
• Standard versions will connect 1/16 in. O.D. tubing to each of the three available ports
• Stainless-steel needle is inside the valve

† The maximum internal volumes listed in the chart are with the valve fully open.
