VACUUBRAND PC 620 Select Chemistry Pumping Unit Ultimate Vacuum 1.5 mbar (1.1 Torr) Maximum Pumping (more) Speed 2.2 CFM at 60Hz Number of Heads/Stages 4/3 Features - VACUU-SELECT vacuum controller with graphical user interface simplifies work in the laboratory - Predefined applications save time and give reproducible result - Easy-to-use application editor allows own process sequences - Meets high vacuum requirements for most high boiling solvents - PC 620 select allows simultaneous operation of two independent vacuum applications with electronic vacuum control This chemistry vacuum pumping unit is an economical, compact solution for simultaneous operation of two electronically controlled vacuum applications with a single pump. Based on our popular MD 4C NT three-stage chemistry diaphragm pump, the PC 620 select is frequently used for vacuum applications involving even high boiling point solvents. This pump has sufficient capacity to run two demanding applications simultaneously. Both vacuum ports have independent solenoid valves for electronic vacuum control, and check valves to protect against cross contamination and interference. The integrated VACUU-SELECT controller provides an easy-to-use, application-based interface that covers all common lab applications. The VACUU-SELECT controller has you covered. Use manual set-point-control for simple processes, run distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, it constantly monitors the pressure and switches to a 2-point control mode to hold the pressure stable when a boiling point is detected. The inlet separator, made of glass with a robust protective coating, prevents particles and liquid droplets from entering the pump, preventing damage, and extending pump life. And the exhaust vapor condenser allows for nearly complete recovery of solvents when used with a chilled water line or recirculating chiller for economical recycling and environmental protection. INCLUDED: The VACUUBRAND PC 620 Select Chemistry Pumping Unit includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

PS R2.H series balances redefine the level of standard precision balances. Not only do they share al (more)l the features of R series balances, but can also work in adverse operating conditions (condensed dust, drops of water falling down at different angles typical for IP 54). LCD display These balances are equipped with innovative LCD display allowing for clear and legible presentation of a measurement result. Moreover, it offers new text line which supplies the user with some additional messages and information, e.g. product name or tare value. Interfaces Additional asset of PS R2.H balances are their interfaces build-in a hermetic closed housing which is separated from the balance. The interfaces include 2×RS 232, USB type A, USB type B, and Wireless Connection optionally. Balance housing is made of plastic, whereas its pan of stainless steel. Under-pan weighing Weighing instruments purchased after 15th February 2023 will allow under-pan weighing at any time after the purchase. All you need to do is just to order a dedicated hook.
