Pumps efficiently transport liquids or remove moisture and gases from a variety of different-sized containers. The devices are used for dispensing and general liquid-handling purposes. Ergonomic, handheld designs allow for continued comfort and one-handed operation. For the best reproducibility, digital pumps can be programmed to dispense precisely measured samples into culture plates, vials, tubes, or bottles. Pumps can measure in different units depending on preference.

VWR® SD 820, Vývěva membránová, samovysoušecí na vlhké plyny, dvoukomorová
Supplier: VWR Collection
Membránová vývěva se samovysoušecím systémem pro vlhké plyny. Toto zařízení lze v laboratoři použít pro široký rozsah aplikací, zvláště při potřebě tvorby čistého podtlaku při současném odsávání plynů s vysokým obsahem vlhkosti. Jako například systém vakuové sušicí komory (pro sušení nebo tepelné ošetření sloučenin a složek) nebo parních sterilizátorů (při parní sterilizaci nástrojů, nádob, filtrů a textilu). Toto zařízení lze použít pro široké laboratorní aplikace, jelikož se vyznačuje vysokou odolností vůči agresivním složkám. Membrána vývěvy je potažena vrstvou PTFE a je vybavena patentovaným systémem optimalizace pnutí, díky čemuž je zařízení malé a membrána vydrží déle bez nutnosti servisu. Díky novému systému samovysoušení dochází během tvorby podtlaku k vytlačení kondenzátu z hlav čerpadla vysokou rychlostí. Podtlak v podtlakové komoře zůstává stejný. Sušicí cyklus lze nastavit podle konkrétních požadavků dané aplikace pomocí třech proměnných. Po vysušení vývěva dosahuje lepšího podtlaku a je schopna vytvořit podtlak rychleji ve srovnání s vývěvou bez sušicího systému.

VWR® VP 220, Chemical Duty, High Performance Diaphragm Pump
Supplier: VWR Collection
The VP 220 is ideal for rotary evaporators providing the powerful vacuum needed for demanding evaporations without the use of oil pumps. VP 220 has built-in Advanced Vapour Management (AVM) which means precise control capability for the distillation of organic solvents and applications handling aggressive vapours and gases. The VP 220 is especially effective for rotary evaporation of low boiling point solvents such as acetone and ethanol and is able to rapidly strip DMF at 35 °C. The pump parts are all made of corrosion resistant materials such as PTFE and Kalrez to handle aggressive vapours, and together with vacuum adjustment, the evaporation process will be optimised. Use the vacuum adjustment to increase the vacuum until bubbles form in the evaporation flask - then lower it slightly. Reduce the vacuum for fast reaction to bumping or foaming.
