Fume Cupboard Maintenance

It is crucial that your Fume Cupboards are serviced on a regular basis, to ensure the safety of the equipment operators and minimise the risk of the product failing. It will also make sure that the laboratory apparatus runs effectively and efficiently, with little technical issues.
