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.
