|MEDIUM PRESSURE INJECTION PORT ADAPTER|
|Our simple, biocompatible adapter converts any 1/4-28 flat-bottom port into a port that can accept a standard 22 gauge HPLC injection needle. This injection port adapter is adjustable, so you can create a snug fit around the needle to prevent any leaking of the analyte. In addition, this product features an internal stop that prevents you from inserting the needle too far, eliminating the possibility of damaging the valve with the needle tip.|

- For Medium Pressure Applications / Biocompatible, All-Polymer Flow Path / Available for 1/16" and 1/8" OD Tubing
Stop a flow stream quickly with Upchurch Scientific® biocompatible Shut-Off Valves. The bodies are manufactured from either PEEK™ or TefzeF® (ETFE) with a Kel-F® rotor, making them highly resistant to chemical attack. The blue colorant used in some valve configurations has proven not to leach out with common HPLC solvents.
Connect semi-rigid or rigid tubing, such as PEEK, stainless steel or Teflon®, with the 1/4-28 Flangeless Fittings provided. Soft tubing, such as Pharmed® or Tygon® , may be connected to these valves using our 1/4-28 barbed adapters.

- For Interfacing LC-MS Systems / Split Stream Flow Rates as Low as 2µl/min. / Medium and High Pressure Versions
|MICRO-SPLITTER VALVE INFORMATION||Upchurch
Scientific® offers a line of Micro-Splitter Needle Valves designed to
accurately split and control a low-flow stream off a single incoming
The biocompatible Medium Pressure Micro-Splitter Valves are perfect for LC-MS and other multidetector systems, and fraction collectors. The ideal placement of these valves is on the effluent side of the detector flow cell, at a maximum pressure of 800 psi (55 bar). Choose between 1/4-28 and 10-32 threaded versions. A valve is also available to accommodate applications involving capillary tubing.(1)
The High Pressure Micro-Splitter Valves are designed to operate under pressures up to 4,000 psi (276 bar). These products are well suited for running two analytical devices in parallel. The High Pressure Capillary Micro-Splitter Valves (1) may also be used to adapt an analytical HPLC system to handle microbore applications.
Our Graduated Valves offer many of the benefits and features of our original Micro-Splitter Valves, plus the ability to adjust and set the split flow to repeatable settings. This allows documentation of settings and the resulting flow rates for easier method development. The graduations also make it easier to employ the valve in a system used to run multiple analyses that require different split flow rates. Choose from regular High Pressure and Capillary (1) versions.
All Micro-Splitter Valves have been tested at flow rates to 100ml/min., with a maximum resulting pressure drop of only 45 psi (3.1 bar). (2)
(1)This valve has a MicroTight ` 6-32 threaded fitting on the split stream Select the appropriately sized Micro Tight Tubing Sleeve to connect your capillary tubing.

VALVE FOR WATER® PUMPS
- Automatic Valve Operation with a Simple Twist of a Luer Lock Syringe /
No Tubing to Cut or Ferrules to Swage / No Wear on the Internal Seal
For Any Style HPLC System / Automatic Luer Syringe Operation / Featuring Handy Mounting Holes
Upchurch Scientific® Prime/Purge Valve for Waters pumps automatically
opens when a luer syringe is attached and closes when the syringe is
removed. No valve rotation is required after the initial installation, so
wear on the internal seal is eliminated.
In addition, our Waters-compatible Prime/Purge Valve is simpler to operate and more economically priced than alternative valves available for Waters systems. This valve is constructed of rugged materials, including a PEEK™ valve body. The component structure ensures compatibility with virtually all common solvents used in HPLC analyses. A Waters-compatible internal Teflon® seal is included with the valve. This seal can also be purchased separately. It can be used both with the Upchurch Scientific valve and the original valve supplied with the pump.
Scientific Universal Prime/Purge Valves are easy to operate. Simply
install a valve along the flow path with the included fittings and attach
a luer-tipped syringe. Then, withdraw the plunger and watch as solvent and residual bubbles are removed from the solvent line. The valves automatically close when the syringe is removed.
The low pressure version of the valve is designed to be used with 1/8" OD tubing, while the high pressure version accommodates 1/16" OD tubing. Optional mounting is made easy by the handy holes in the body of each unit.
|Air in the
Air within the pumphead can cause flow instability and noisy pump operation. Place the High Pressure Prime/Purge Valve between the pump and the sample injector, where it can be used to remove bubbles that have become lodged within your pump. This valve is rated for a maximum pressure of 5,000 psi (345 bar).
in the Inlet Solvent Line
Install the Low Pressure Universal Prime/Purge Valve along the inlet solvent path near the pump to remove bubbles from the inlet solvent line. The valve can also be used to rapidly "wet" your solvent inlet filter. When a new filter is installed, it often contains a substantial amount of air within its pores. At standard flow rates, it may require several minutes before the inlet fluid pathway is completely free of gas. Using this valve, you are able to rapidly draw solvent through the inlet filter, dislodging the gas and minimizing downtime.
