Aspirator, Hand-Evac handheld vacuum controller with pipette tip adapter The HandE-Vac handheld aspirator will rapidly remove supernatant from a variety of cell culture or multi-well plates and dishes. This conveniently designed aspirator can be used with Pasteur pipettes, plastic aspiration pipettes or a variety of small laboratory vessels. A number of adapters are available for specific applications. The pressure-sensitive button on the top of the unit controls the specific amount of vacuum applied. This prevents the accidental aspiration of cells or supernatant associated with normal vacuum techniques. The unit can be used with a standard in-house vacuum source or with the P-Vac portable aspirator; it is possible to autoclave the unit and is supplied with a single-channel adapter for disposable pipette tips.
