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.

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.

Jednotky VCP 80 a VCP 130 mohou být použity jako účinná vakuová a tlaková čerpadla. Čerpadla jsou vhodná k tvorbě vakua v aplikacích, kde není vyžadována odolnost proti korozi. Čerpadla mohou být použita pro vakuovou filtraci vodných roztoků nebo vodních výparů včetně pufrů, ale nedoporučují se pro čerpání kyselých, zásaditých nebo organických výparů. Tato vakuová / tlaková čerpadla řady VWR® Collection mohou pracovat nepřetržitě a bez potřeby obsluhy, mají dva manometry s analogovým ukazatelem pro nastavení a snadné sledování požadované úrovně vakua nebo tlaku.
