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 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\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMax. pumping speed 50 Hz: 3.4 m 3 \/h\u003c\/li\u003e\n\u003cli\u003eMax. pumping speed 60 Hz: 2.2 cfm\u003c\/li\u003e\n\u003cli\u003eUltimate vacuum: 1.5 mbar \/ 1.1 torr\u003c\/li\u003e\n\u003cli\u003eUltimate vacuum with gas ballast: 3 mbar \/ 2.2 torr\u003c\/li\u003e\n\u003cli\u003eNumber of heads: 4\u003c\/li\u003e\n\u003cli\u003eNumber of stages: 3\u003c\/li\u003e\n\u003cli\u003eVacuum controller: VACUU·SELECT\u003c\/li\u003e\n\u003cli\u003eLower ambient temperature (operation): 10 °C\u003c\/li\u003e\n\u003cli\u003eUpper ambient temperature (operation): 40 °C\u003c\/li\u003e\n\u003cli\u003eLower ambient temperature (storage): -10 °C\u003c\/li\u003e\n\u003cli\u003eUpper ambient temperature (storage): 60 °C\u003c\/li\u003e\n\u003cli\u003eMax. back pressure (abs.): 1.1 bar\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Vacuubrand","offers":[{"title":"Default Title","offer_id":59518122066252,"sku":"20737353","price":9825.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/20737353.jpg?v=1792971930","url":"https:\/\/www.luminixhealth.com\/nl-nl\/products\/pc-620-select-us-20737353","provider":"Luminix Health","version":"1.0","type":"link"}
