vacuum pump

Voorbeeldzinnen

1. Vacuum line (turbo pump)
2. Use a vacuum pump
3. To vacuum pump
4. Vacuum pump or compressor and reservoirs
5. The ultimate vacuum is determined at the input of the pump with the input of the pump blocked off.
6. In the latter instance, disconnect the vacuum pump when the prescribed pressure has been reached.
7. The latter consists of a vacuum pump, a buffer volume, a manostat for admitting nitrogen for pressure regulation and manometer.
8. The method involves placing a sample in a bulb maintained at constant temperature and connected to a manometer and a vacuum pump.
9. Adjustable electrically heated vacuum oven fitted with an oil pump and either a mechanism for introducing hot dried air or a drying agent (e.g. calcium oxide).
10. Fountain, stylograph and other pens with body/cap of precious metal/rolled precious metal including pump, cartridge, plunger/vacuum type pens excluding ball point/porous-tipped pens
11. To improve the pump performance and to obtain a stable baseline, degas the mobile phase daily by selecting one of the available techniques such as sparging by helium, sonication, vacuum or in-line degassing system.
12. The outlet is connected to the pressure regulation system. The latter consists of a vacuum pump, a buffer volume, a manostat for admitting nitrogen for pressure regulation and manometer.
13. Adjustable electrically heated vacuum oven fitted with an oil pump and a mechanism for introducing hot air dried through a tower containing for example calcium oxide or calcium sulphate (containing moisture indicator)
14. i. Multiple-seal, and seal-less pumps, with manufacturer's specified maximum flow-rate greater than 0,6 m3/hour, or vacuum pumps with manufacturer's specified maximum flow-rate greater than 5 m3/hour (under standard temperature (273 K (0 °C)) and pressure (101,3 kPa) conditions); and casings (pump bodies), preformed casing liners, impellers, rotors or jet pump nozzles designed for such pumps, in which all surfaces that come in direct contact with the chemical(s) being processed are made from any of the following materials:
