Digital Vacuum & Pressure Gauges 14063-10 Precision Vacuum Regulator  Perfect for vacuum distillation, unit automatically compensates for leaks in the equipment under test and maintains precise pressure, even in systems with a continuous gas purge. This computer (built-in) controlled vacuum regulator maintains pressure in the range of 0.1 to 760 Torr (atm pressure) in test instruments with volumes as small as 1 mL. Standard features include 16-step programmable pressure ramp and serial communications for PC control and data logging. Ace Glass proudly introduces the entire J‑Kem product line of temperature and vacuum controllers. J‑Kem has established a leadership role in product performance and innovation over the past several years, offering both monitors and controllers for pressure, vacuum and temperature that cover the entire spectrum of product performance. Whether you need a simple monitor or an advanced controller, the ACE/J‑Kem advantage offers it all. The J‑Kem line features their KemNet software for data logging and control, as well as updated performance, and options like CE certification and USB data ports, as standard.

ACE GLASS • J-Kem Digital Vacuum & Pressure Regulators Connect to any vacuum pump or vacuum source, and then to any piece of equipment, to regulate pressure, in most cases to ±1 Torr. A standard pressure ramp feature evacuates equipment at a user-defined rate to eliminate bumping due to solvent degassing or over-evacuation. Ideally suited for large volume distillations, rotary evporators and vacuum chambers. Not recommended for small volume distillations or applications which involve a continuous purge with gas. 14061-08 Vacuum Regulator  No Mercury  Designed for vacuum systems that run continuously,...
