'silent' Microbiological Safety Cabinet at Achema

Kojair Tech Oy, based in Finland, is launching its new Biowizard Golden Line Class II range of microbiological safety cabinets. They offer protection and optimal working conditions to the user during the handling of hazardous and potentially hazardous organisms, as well as protection to the environment because the discharge to atmosphere is HEPA-filtered.

The principal feature of the company's new clean-room-compatible Biowizard Golden Line Class II cabinets is that they are virtually silent in operation, generating under 52dB(A). At 13dB (A) below the requirement of EN12469 of 65dB(A), the new cabinets offer operators the highest available standards in their working environment. Kojair Tech is currently in the process of patenting the unique construction of the Golden Line units.

The first of the new cabinets has already been delivered to Helsinki University. Denmark's Biocenter in Copenhagen has placed an order for 56 cabinets. Ten more Biowizard Golden Line cabinets are destined for Switzerland and further units have been ordered by a number of German companies.

Users tend to work for long hours in close proximity to microbiological safety cabinets. Feedback from users all over the world and recommendations from the European Agency for Safety and Health at work, which studies the effects of work-related-noise, have influenced the design of the new Kojair models. Noise can put an undesirable load on the brain, which may lead to physical or mental harm. Not only can high sound levels affect hearing, they can also increase stress levels and blood pressure as well as reduce concentration, creativity and comprehension.

The new Biowizard Golden Line cabinets offer not only quiet running and protection against hazardous organisms. They have also been developed with advances in practical ergonomics, user comfort and a streamlined, easy-to-clean design in mind.

Four cabinet models are available with working widths of 885 mm, 1190 mm, 1535 mm and 1840 mm x 570 mm deep x 740 mm high, which are mounted on an adjustable base unit. The electrically operated front window is slanted backwards (away from the user) to give a clear view of the work area. Fully adjustable light tubes - from 750 to 2000 lux - ensure shadow-free lighting over the whole working area. An arm support is provided for the comfort of the operator when handling specimens.

A 3-filter version of the Biowizard Golden Line to meet the requirements of Class II B (DIN 12980) is also available.
