Heidolph Hei-VAC Diaphragm Vacuum Pump

The N 820.3 FT.40.18 is a two-stage pump with an integrated “self-drying” system for automatic conde (more)nsate drain. The “SD” series is widely used in laboratories, especially when the vapors are humid and a clean and ecological vacuum is required. Typical applications are: vacuum ovens (for drying chemicals, drying biological samples, heat treatments), autoclaves for sterilizing instruments, containers, filters and textiles. Thanks to the use of anti-corrosion materials, it is possible to vacuum even corrosive products.  The heart of the pump is the diaphragm with differentiated structure in PTFE, optimized to guarantee high performance with reduced dimensions and at the same time, long life even in heavy applications.  When the humid gases are sucked in, condensation may form in the pump head: consequently the performance decreases, considerably increasing the emptying time. To eliminate condensation, the 'drying system' then opens a solenoid valve that allows ambient air to enter the heads. Once the condensation has been eliminated, the solenoid valve closes and the pump sucks from the stove in full capacity. Over time, condensation could form again and then the cycle is repeated. The time interval between one cycle and the next can be adjusted as desired, as well as the duration of the air injection.

VACUUBRAND PC 611 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 611 Select allows simultaneous operation of two independent vacuum applications with electronic vacuum control This chemistry vacuum pumping unit is an economic space-saving solution for simultaneous operation of two independent vacuum applications with one single pump. Based on our popular MD 4C NT three-stage chemistry diaphragm pump, the PC 611 select is frequently used for vacuum applications involving even high boiling point solvents. This pump has sufficient capacity for parallel operation of two demanding applications. One application is controlled by the VACUU-SELECT vacuum controller, via an electronic solenoid valve. The second application is controlled by a manually controlled diaphragm valve. Both vacuum ports have integrated 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 detects the boiling pressure and switches to 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.
