Laboratory Air Cleaning

Laboratory air cleaning is a top priority for many laboratories, as the widespread use of formalin and xylene in pathology and histology laboratories can cause elevated contamination levels and therefore long term exposure of staff and work processes to elevated formalin and xylene levels.

Standalone laboratory air cleaning systems, which require no ducting or specific installation work, are the ideal solution. Commercial Air Filtration is specialised in working with Pathology and Estates Managers to specify the effective and cost-efficient solution for each laboratory environment

Protect Staff

How many staff put themselves at risk in their labs because they don't know if their laboratory air cleaning systems are working correctly? Fume hoods and cutting benches are often the biggest culprits - the equipment is still running day after day, but is it still performing laboratory air cleaning well enough?

One of the major expenses in laboratories is the heating and cooling of the air. Commercial Air Filtration’s high-performance stand-alone laboratory air cleaning units maximize fume capture while recirculating the already warmed (or cooled) laboratory air.

The broad range of airborne contamination which can be effectively controlled by our laboratory air cleaning units include:

  • VOCs
  • Ozone
  • Formaldehyde
  • Chloroform
  • Xylene

In Microbiology Labs, the overall airborne environment can be kept clean by the use of IQAir high-performance standalone laboratory air cleaning units to recirculate the air. These units can be set up to deliver a significant number of air exchanges in each separate workroom, depending on the type and extent of each contamination. The filtration media in each unit is specified directly for the particular contaminant:

  • MultiGas – Granular activated carbon and impregnated alumina (AC/4 + IA/4)
  • VOC – Granular activated carbon (AC/4)
  • ChemiSorber – Granular impregnated alumina (IA/4)
  • AM – Granular impregnated activated carbon (AC/4-AM)
  • AcidPro – Granular impregnated activated carbon (AC/4-K)

Protect Processes

Many laboratory environments have a high-velocity air conditioning system (HVAC) installed to meet building regulations. These systems can have an unintended negative impact on indoor air quality. Rather than provide clean air, HVAC systems often bring additional contaminated air into the laboratory. Recirculating standalone laboratory air filtration units avoid any such problems.

The research itself can also be compromised by different chemicals interacting with each other. Even seemingly enclosed tissue processing machines can be a cause of contamination when opening and replenishing chemicals.

The effective solution is the use of high-performance standalone laboratory air cleaning units which can operate with no ducting and no permanent installation. Each can be configured to remove a specific airborne contaminant, or range of contamination, including the major contaminants, causing most laboratory air filtration problems:

  • Aldehydes
  • Mercurials
  • Alcohols
  • Oxidising Agents
  • Picrates
  • Hot Paraffin Wax
  • Particulates

As a self-contained unit, the IQAir laboratory air filtration unit requires only a regular electricity socket, and the unit can be placed directly at the source of any contamination. The dedicated wall mount, together with the range of accessories allowing local source capture, enable the units to be mounted exactly where you need them.

Control Fixative Fumes

During the fixing process, the highest risk of formalin exposure occurs during filling of containers and transferring of samples. As each of these steps requires formalin to be exposed to air, allowing gas and vapour into the laboratory, laboratory air filtration is essential.

In order to avoid exposure to formalin fumes, it is vital that during any point in your process where formalin is exposed to air, a high-performance air filtration unit is cleaning the air within the work area. The IQAir FlexVac accessory enables each air filtration unit to perform source capture of fumes before exposing any laboratory staff.

Tissue Processing

Many enclosed tissue processing machines used in histology laboratories emit significant amounts of formaldehyde and formalin fumes. In often enclosed laboratory workrooms with less than ideal ventilation, the build-up of gases can have a profound effect on staff. The high-performance IQAir GCX laboratory air filtration unit, placed in the same workroom, can perform effective air cleaning of the space and provide a sufficient rate of air exchanges to keep workers free from these problem fumes.

air quality in ivf labs Since the birth of the first baby from in-vitro fertilisation (IVF) in 1978, Assisted Reproductive Technology (ART) has grown in importance as techniques and success rates have continued to improve. All cells, including gametes (sperm and egg) and embryos (bundles of cells) are very sensitive to laboratory conditions of temperature, pressure, composition of the medium they are handled and grown in, and also air quality. We will examine air quality in if labs, and provide you with the best recommendations.

gas and chemical hazard control A recent leak of ammonia from a fridge caused the evacuation of 27 patients from a ward at Sunderland Royal Hospital. The incident was promptly and efficiently dealt with by specialist firefighters but is a reminder of how good gas and chemical hazard control is essential.

There has been a revolution in awareness of chemical air pollution in research laboratories. I could tell you several 'horror stories' of casual exposure to mercury vapour, benzene and chromic acid (the ultimate glassware cleaning agent) among innocent biomedical PhD students (including myself) in the 1970s. But researchers in hospitals, and other laboratories can never afford to be complacent about exposure to chemical air pollution, because there are so many different substances involved – and we still do not know too much about the long-term health effects of so many of them.
