A variety of valves that can, depending on the product, be used to regulate pressure levels of liquid and gas in flow systems. These valves can be used for making connections between different lengths of tubing and connection points. Liquid and vacuum seals. A plethora of scenarios exist in which these valves can be used, each with a unique purpose and design for maximum safety and efficiency when in use, especially when pressure is of great concern.
Description:
Bore Range (mm); 0-20. Approx. Stem O.D. (mm); 22. O-Ring Size Shaft; 210. O-Ring Size Tip; 208 For vacuum applications up to 5 x 10-7 Torr. Designed with a precision external thread for fine control.
Description:
Bore Range (mm); 0-8. Approx. Stem O.D. (mm); 13. O-Ring Size Shaft; 110. O-Ring Size Tip; 108 This valve uses a glass plug (as an alternative to PTFE or CTFE) for applications where the "out-gassing" plug material is undesireable.
Description:
For vacuum applications up to 5x10-6mm Torr. PTFE shaft can handle system temperatures of 230[degree]C continuously or intermittently at 275[degree]C. Primary seal made with Viton* O-ring. Bore range: 0-4mm. Stem OD: 9mm. O-ring shaft: 6.07IDx1.78Wmm. O-ring tip: 3.91IDx1.27Wmm.
Description:
Designed for applications that require an evacuated apparatus be filled with an inert gas to one atmosphere. Uses include introducing an inert gas into a vacuum desiccator or nitrogen into an AIRLESS-WARE* apparatus. #2 hose connector. Overall height: 13cm.
Description:
For vacuum applications up to 5x10-6mm Torr. PTFE shaft can handle system temperatures of 230[degree]C continuously or intermittently at 275[degree]C. Primary seal made with Viton* O-ring. Bore range: 0-8mm. Stem OD: 13mm. O-ring shaft: 9.19IDx2.62Wmm. O-ring tip: 7.65IDx1.78Wmm.
Description:
Bore Range (mm); 0-8. Approx. Stem O.D. (mm); 13. O-Ring Size; 110 Sidearms are bent to minimize liquid holdup that would occur in conventional valves. PTFE shaft seals protect the Viton o-rings from contact with the system.
Description:
Manual injection valve, 6-port rotary valve that is manually operated to transfer the preloaded sample onto the column. The sample loop (for the injection of small sample volumes [25 ul to 5 ml], or a Superloop injection loop for larger sample volumes [10 to 150 ml])
