Fluid aspiration system
BioChem-VacuuCenter (BVC)

Safe, sensitive and efficient aspiration of liquid supernatants: this is the strength of our BioChem-VacuuCenter. The optimized system series for liquid aspiration can be used in laboratories of biological protection levels 1 (S1) to 3 (S3). It also has a modular design: Depending on the laboratory equipment, choose the basic version for connection to existing external vacuum sources or our complete units with built-in chemically resistant diaphragm pump.

Range of application

Your bodyguard for working with infectious fluids with the safety cabinet

Our BioChem-VacuuCenter BVC liquid aspiration systems offer uncompromising safety and more comfort at work. Depending on the safety requirements, the BVC systems are available with different equipment and can thus be used safely in biological safety areas of protection levels 1 (S1) to 3 (S3).

Our equipment is designed to be placed outside the workbench. This saves space on the work surface and the low-turbulence air flow of the safety cabinet remains unaffected. Another advantage is that the components of our systems are optimally compatible to each other. In contrast, individually created, non-standardized extraction devices often harbor unexpected risks in this respect.

Overview of the safety features of the BVC systems

A safe system

All components of the BVC are designed for use in the biochemical laboratory and are perfectly compatible to each other. The result is a well designed, vacuum-tight system with safe connections where no critical substances can leak out or bacteria can grow undesirably.

All systems are available either with a vacuum-resistant, autoclavable 4l PP bottle or with a 2l borosilicate glass bottle, e.g., for working with aggressive disinfectants such as chlorine bleach. BVC's collection bottle can be easily and safely disconnected and reconnected for disposal of liquid biological waste. Simple extensive cleaning and disinfection of the components.

Efficient and comfortable working

In addition to the safety aspect, BVC systems are also outstanding in terms of functionality and ergonomics. The new aspiration hand set VHCpro was designed with the experiences of many users in mind. The result is a hand set that fits perfectly in the hand and offers ideal conditions for fatigue-free work.

With the BVC professional and BVC control, you can regulate the suction force easily and precisely via a touch panel. Continuous suction can also be set for larger quantities of liquid. The ease of use is further enhanced by the fact that the chemically resistant diaphragm pump switches on and off automatically as needed. This makes the already low operating noise even quieter.

Flexible and economical solutions

Choose your suitable BVC system for use on an existing vacuum supply or as an all-in-one solution with integrated vacuum pump: Our powerful chemical-resistant diaphragm pump is characterized by a very long service life – even when working with aggressive disinfectants. That's why our BVC system works reliably over the long term and with minimal maintenance.

Depending on the safety requirements, the BVC systems are available with different equipment. This allows you to use them safely in biological safety areas of protection levels 1 (S1) to 3 (S3). Safety-relevant accessories such as self-closing quick couplings can be added at any time. By connecting a second suction hand set, an economical dual use of the devices is possible.

FAQ

For which safety levels are the BVC systems suitable?

Basically, suitability always depends on the applicable regulations for the respective work area. Depending on the requirements and equipment, the BVC systems can be used in laboratories of safety levels 1 to 3. The BVC professional offers the highest level of safety. It is additionally equipped with safety-relevant accessories such as a non-contact level sensor and self-locking quick couplings. For work with critical substances, the BVC systems also have a connection on the rear side via which the exhaust air can be discharged separately.

What is the difference between BVC control and BVC professional?

Both systems have an integrated chemistry diaphragm pump. The suction force can be precisely adjusted via touch panel.

BVC professional is additionally equipped with a non-contact level sensor, a disinfection routine for the suction hose and self-closing quick couplings for maximum safety and optimum biocontainment.

Are the components autoclavable?

Both the VHCpro handle and the collection bottle with connectors are autoclavable. The filter can also be autoclaved up to 20 times. When autoclaving, you must ensure that the pressure between the collection bottle and the autoclave is equalized. This is done by simply loosening the screw cap.

Which collection bottle should I use?

The choice between the PP and the glass bottle depends on the media that will be aspirated. In most cases, the chemical resistance of the PP bottle is absolutely sufficient. The glass bottle is also suitable for working with particularly aggressive disinfectants such as chlorine bleach. The bottle is made of borosilicate glass and has a shatterproof coating and leak protection.

Are there multiple adapters for the suction hand set?

An 8-channel adapter for pipette tips with ejector is available as an accessory. It is designed for parallel aspiration with eight pipette tips (size 2-200 µl or 5-300 µl) from 96-well microtitration plates of standardized size. It is equipped with an ejector for removing the pipette tips.
