Safety Cabinet Type B2 – Claire® total
Safe for chemicals due to Total Exhaust
SAFETY CABINET CLAIRE® TOTAL – SAFETY FOR CRITICAL WORK
Claire® total models are particularly suitable for work in combination with volatile toxic compounds or also with radioactive labelled substances and viruses particles.
They represent a special device type for the handling of biological and chemical hazardous substances under aseptic, low particle conditions. The concept uses an air conveyance system without recirculation into the work space.
In the working space a uniform laminar flow is generated. A series of high-efficiency cartridge filters as the main filter stage retain particulate matter from the total airflow which is removed by a fixed exhaust air system.

TYPE A2 AND B2 COMPARISON

And on the right, of a safety cabinet of Class 2/Type A2 with recirculation.
For Claire® total, an air conveyance concept without circulation or recirculating air in the work space is used, compared to conventional safety cabinets of class 2 (Type A1 or A2).
Around 70% of the total volume flow in the safety cabinet is sucked in from the laboratory via roof-side fans and cleaned via pre-filters and a large H14 HEPA filter. In this way the laminar displacement flow (downflow to 0.45 m/s) for aseptic working conditions is generated inside the work space, typically with cleanroom class A according to the EU GMP guidelines or ISO class 5 according to ISO EN DIN 14644-1.
About 30% of the total volume flow is sucked in at the work opening, the inflow is 0.51 m/s. This serves to create the retention capacity for personal protection through a stable air curtain. Hazardous substances released during activities cannot enter the laboratory air.
A strong main fan supplies 100% of the total volume flow to the laboratory exhaust system.
SPECIAL REQUIREMENTS FOR THE EXHAUST AIR CONNECTION
For safety cabinets of class II Type B2, a fixed permanent connection to the laboratory exhaust system has to be provided, so that the exhaust air is safely guided out of the building. With Claire® total, a built-in, high performance fan supports the discharge of air into the exhaust air conveyance system.
In the planning process the following should be considered :
- Direct, permanent and specifically to the safety cabinet assigned connection to the exhaust air system
- Exhaust air system with own terminal fan, adapted to the exhaust air volume
- Mutual monitoring of the function of the safety cabinet and the exhaust air system with alarm and emergency shutdown, for this there are potential-free contacts in the Claire® total available
- Shutters in the exhaust air system for shutdown and decontamination by fumigation

Optional & Accesories
Various interfaces and additional power sockets
Interfaces allow to connect different kinds of devices within the safety cabinet. Therefore, type and quantity of the interfaces are different according to the need. Find some of the interfaces of our assortment here.
Interfaces :
- RS 232 -> Important data (for example, from a balance, keyboard, etc.) can be send with the integrated RS-232 Data Link from the working space to the data processing system.
- USB/USB 3.0 -> Integrated universal interface for connecting peripheral devices such as keyboard, printer, balance, etc. outside of the working space and laterally disposed of the safety cabinet with your data processing system. Mechanically stable and simple plug-in connection with fast data transfer rate. Gross data transfer rate USB 3.0: 500 mb/s
- CAT 5 -> Integrated interface for signal transmission with high data transfer rates. It enables the exchange of data between a local area network (LAN) connected devices (computers, printers, etc.).
- PS/2 -> Serial interface for input devices such as Keyboard and mouse.
- 8 P -> Push/Pull Interface realised from working space to the roof (Roxtec). 8P push-pull -> circular connector connections. For Claire safety cabinets, for example, for connecting compounders or other
- Ethernet -> Integrated dual interface for signal transmission with high data transfer rates. It enables the exchange of data between connected devices (computers, printers, etc.)in a local area network (LAN).
Powerful systems for UV-C disinfection
The built-in UV C sterilisation system disinfects with a large disinfection effectiveness the workspace thanks to its high performance and shadowfree irradiation. A high irradiance at a wavelength of 254 nm ensures a rapid killing of microorganisms (for example, about 220μW / cm² according to the manufacturer of UV lamps for models with a width of 190 cm).
From this theoretical LD90 values (kill rate: 90%) yield of vegetative bacterial cells and yeast of <2 minutes, bacterial spores (Bacillus subtilis) <5 minutes DNA and RNA viruses gen gen <3 minutes, mushrooms <10 minutes. Few specific exemptions of certain viruses and fungal spores require higher exposure times, so as Aspergillus Niger (spores) about 25 minutes and specific HIV Virus (H9) 40 min.
The appropriate exposure time can be set via the timer on the centrally located touch screen.
Low vibration weighing worktops
Achieved as a mass-spring system the work plate for balances provides a very stable, low-vibration area integrated into the safety cabinet. For undisturbed exact weighing or for other vibration sensitive analytical instruments.
The weighing top has a size of 313 x 600 mm and is made from 1,5 mm thick stainless steel.
The vibration (RMS) could be significantly reduced with the Low-Vibration-System below 5µm (benchmark in relevant technical standards).
The low-vibration area is indicated by a balance symbol.
Isokinetic sampling probe for particle monitoring
Continuous particle monitoring
Determination of particle purity class in the working space of a safety cabinet – or horizontal cabinet or an isolator
- Monitoring the particle purity class A in the working space
- Integration of a fixed or mobile isokinetic sampling probe
