Following our experience in trying to specify the correct construction parameters and HVAC/conditioning system for a lab that complies with ISO 3402 we had a major revelation.


This is incredibly difficult because it is expensive to do it well.


The ideal lab has specially insulated walls and ceilings, no windows and possibly a pressurized air plenum in the ceiling to generate the gentle non-turbulent airflow required especially for smoke laboratories.


Through our laboratory consultancy work we have developed a relationship with a specialist company, Parameter Generation Control in North Carolina, USA who has supplied HVAC/conditioning systems for several smoking laboratories and also supplies Pharma with stability chambers.


Together we are now able to offer a brilliant solution. Instead of just supplying a smoking machine or test station we can now offer “lab in a box”.


This comprises a pre-fabricated all-enclosed room containing the insulation and HVAC/conditioning system with the pressurized air plenum that ensures compliance with ISO 3402 together with the smoking machine, test station or other laboratory equipment required.


The entire ‘solution’ is available to be procured, installed and supported as a complete package. The “lab in a box” can simply be installed almost anywhere inside an existing laboratory, on a factory floor or in a warehouse, in fact almost anywhere that the customer has space available
