Čerpadla

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.

Benchtop aspiration system, VACUSIP

Benchtop aspiration system, VACUSIP

Supplier: Integra

In the laboratory small volumes of liquid need be disposed of on a daily basis. This includes the removal of excess liquids from reaction tubes, aspiration of supernatant after centrifugation steps, removal of washing solutions from microplates and much more. This is often accomplished by self-made systems consisting of a trap flask, a rudimentary aspiration tool and an external vacuum source.

Fluid aspiration system, BioChem VacuuCenter, BVC basic series

Fluid aspiration system, BioChem VacuuCenter, BVC basic series

Supplier: VACUUBRAND

The VacuuCenter BVC basic is designed for connection to an existing external vacuum source like a diaphragm pump or a vacuum network (e.g., VACUU·LAN®) and does not require electric power. The chemically resistant mechanical vacuum controller always ensures an optimal operating vacuum. The controller opens only when needed thus limiting the gas load on the vacuum source. The evaporation of collected liquid is minimised. The inlet tubing integrated in the bottle head reduces aerosol and foam formation and ensures a long service life of the hydrophobic protection filter. The aspiration system is available either as BVC basic with 4 litre PP bottle or as BVC basic G with 2 litre coated borosilicate glass bottle.

Fluid aspiration system, Biochem VacuuCenter, BVC control

Supplier: VACUUBRAND

VacuuCenter BVC control slouží pro efektivní a praktické odsávání supernatantů. Úroveň podtlaku - a tedy sílu sání - lze přesně nastavovat z elektronického dotykového panelu a umožňuje citlivý a reprodukovatelný provoz. Membránová vývěva odolná vůči chemikáliím se automaticky zapíná a vypíná podle potřeby, čímž se ještě více snižuje nízká hlučnost. BVC control je k dispozici ve dvou kompletních možnostech vybavení s různými sběrnými lahvemi. 2litrová láhev z borosilikátového skla s ochranným povlakem má velmi vysokou odolnost vůči chemikáliím. Pro větší množství kapalin lze použít 4litrovou nerozbitnou polypropylenovou (PP) láhev. Hladké povrchy umožňují snadné čištění systémů.
