Vacuum systems are widely used for aspiration of liquids and their subsequent disposal. Common applications include the removal of media from cell cultures, of supernatants after centrifugation and of wash solutions from immunoassay well-plates.

Protecting the vacuum source from contamination by liquids and aerosols with an overflow trap and a filter is not only good laboratory practice, but also imperative as a personal protection measure when working with biological, chemical or radioactive liquids.

As an alternative to “ do-it-yourself� systems typically found in laboratories, the VACUSAFE aspiration system offers increased safety, exceptional userfriendliness and high versatility. The VACUSAFE is available either as a stand-alone system with integrated vacuum pump or as an instrument that can be connected to existing vacuum sources like a house vacuum pipeline or an external pump.

Safety first: protection for yourself and the lab

The VACUSAFE product range offers different levels of safety depending on the requirements of specific applications. Basic safety characteristics that apply to all models include the:

* hydrophobic filter for vacuum source protection,
* shatterproof bottle for prevention of spills,
* stand for securely holding the bottle in place,
* autoclavability of the system components that contact liquid.

For total containment of hazardous liquids, the best choice is one of the closed systems with additional safety features:

* Integrated pump with vacuum control ( no risk of contaminating house vacuum pipelines and reduced environmental impact by evaporation of volatile solvents) .
* Self-closing connectors for avoiding escape of drops or aerosols from disconnected bottle and tubing.
* Level sensor detecting when the bottle is full and so preventing liquid overflow.

User-friendly system for productive aspiration

A simple routine task like the aspiration of liquids requires user-friendly equipment that is easy to install and convenient to operate. Only so it is possible for the user to fully concentrate on relevant and complex work. Several aspects make the VACUSAFE a convenient tool for productive aspiration:

* All-in-one system includes all necessary components. Consumables and spare parts are always available from the same source.
* Straightforward operation – simply switch on, set the desired vacuum and start working.
* The integrated pump orvalve is switched off automatically when the vacuum is established in the bottle and is switched on again when the vacuum is used – this way unnecessary noise is avoided and the pump’ s lifetime increased.
* The noise of the integrated pump is well below 65 dB( A) , the level recommended by the European agency for health and safety at work.
* The quick tubing connectors speed up bottle removal and also make this operation safer.
* Carrying and emptying the bottle is much easier and safer with the specially designed handle.

Versatile tools for all liquid aspiration tasks

An important component contributing to the versatility of the VACUSAFE system is the vacuum aspiration tool VACUBOY because it can be fitted with different adapters for removal of liquids from virtually every laboratory vessel. The application range is further expanded by the possibility to adjust the vacuum level depending on the needs: from gentle removal of supernatants from an Eppendorf tube or 96-well plate to fast emptying of a large culture flask

The system’ s versatility is increased by the option to connect two VACUBOY aspirators to the same VACUSAFE, which is particularly important for busy laboratories where often two persons work simultaneously in the same biosafety cabinet.
