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

Class M1 mass standards are versatile measuring tools characterized by their high precision and vers (more)atility in laboratory, industrial or commercial applications. Classified as M1 metrology class, they are valued for their versatility and accuracy in mass measurement. M1 mass standard: flat polygonal sheet Nominal value: 2 mg Material: aluminum M1 Class Mass Standards – Key Features High-Level Precision - M1 class mass standards are designed to ensure precision in mass measurements. Permissible deviations from the actual mass are set with strict standards. Versatility of Applications - Characterized by versatility, M1-class standards are used in fields such as laboratories, industry, commerce and other areas requiring precise weight measurements. Measurement Stability - M1-class mass standards are stable over time, meaning that they maintain their measurement precision even despite prolonged use. This feature is especially important for tools that are used regularly. Operation in a Wariety of Ambient Conditions - M1 class mass standards are designed to cope with both laboratory, industrial and commercial conditions. Application 1. Analytical Laboratories In analytical laboratories where precise measurements are crucial, Class M1 mass standards are used to calibrate medium-precision balances. 2. Manufacturing Industry In the manufacturing industry, where product quality control is important, M1 class mass standards can be used to calibrate balances used in the manufacturing process. 3. Weighing Trade In the weighing trade, where measurement precision is required by law, M1 class mass standards can be used as a reference for calibrating commercial balances. 4. Testing Laboratories In research laboratories, Class M1 mass standards can be used to ensure precise weight measurements. Class M1 mass standards are versatile tools that are used in various areas of life. Their ability to adapt to different conditions makes this class of standards highly valued in the world of science, industry and commerce alike.
