Offering a flexible solution to best fit customer needs and applications while effectively achieving GMP Annex 1 compliance

 

Cherwell Laboratories, specialists in cleanroom microbiology solutions are pleased to introduce new models to the ImpactAir range of microbial air monitors that they distribute from Pinpoint Scientific. 

 

The ImpactAir-ISO-90 and ImpactAir-90 ranges aim to support the new EU GMP Annex 1 requirements for continuous environmental monitoring.  They are designed to be used in high-grade areas; within the pharmaceutical, healthcare and specialist food industries; where process monitoring of viable particles can be critical and where ISO-14698, BS EN 17141 and GMP Annex 1 compliance must be satisfied.

 

The monitoring platform used by both range models meets the requirements of these regulations whilst offering flexible solutions that can be tailored to meet the end users’ specific requirements. Benefits are gained from common components and user interfaces being used throughout both model ranges – reducing operator training requirements, reducing risk, simplifying regulator audits, simplifying product support and calibration, and allowing data from different areas to be compared on the same baseline.

 

The ImpactAir-90 and ISO-90 instruments have a chamber for a 90mm Petri dish and use a highly efficient slit to agar method which offers a high degree of confidence in data captured. Air is drawn at high speed through a very narrow inlet slit, whereupon particles, including microbes in the air, impact and stick onto an agar surface in a Petri

dish. The Petri dish is slowly rotated under the inlet, ensuring the air is always ‘impacted’ onto an area of fresh agar. This dramatically reduces the desiccation of the microbes resulting in a very high biological and physical efficiency unmatched by other types of sampler or real-time systems. 

 

Another advantage of the rotating agar plate is that the results are time correlated. Whilst not timed to the second, localised growth on the plate can be time estimated based by its position on the plate. 4+ hours continuous monitoring is possible using a single 9cm agar plate.

 

Andy Whittard, Managing Director at Cherwell commented, “We are really excited by the opportunities that the new range of air monitors from Pinpoint offer. The compact, 90mm Petri version slit-to-agar range can help users address the challenges presented by the new Annex 1 and the focus on continuous monitoring. The various options also provide users with differing solutions for challenges within their facilities.”

 

The ISO-90 Monitoring Head is at the heart of the ImpactAir-90 and ISO-90 microbial air monitors.  It contains all the controls and mechanisms required to rotate the agar plate during the monitoring period.

 

The ISO-90 range comprises of:

The ISO-CON-90 Complete Monitoring System – a complete turnkey monitoring solution for isolators.  A powerful built-in vacuum pump ensures the smooth running of the ISO-90 head at distances of up to 10+ metres away, making it possible to locate the ISO-Con away from the head in a more convenient location.

 

The ISO-90-V-Monitoring Head – designed specifically for isolator manufacturers who wish to perform their own flow control using their own vacuum source.

 

The ISO-90-N-POE Monitoring Head – ideal for bio-safety cabinets or isolators, the size and power consumption of the vacuum pump have been reduced so the pump can fit into the monitoring head and does not require any external vacuum source or pipework.

 

The ImpactAir-90 range includes:

The ImpactAir-90-B/M Portable Monitor –by utilising the ISO-90 head and directly mounting it to a smaller ISO-CON system that incorporates low power electronics, the first battery powered, slit-to-agar air monitor, that is Annex 1 compliant, is now possible. Available as either battery powered with external PSU charger, or mains only version. With a footprint of only 150mm x 200mm, this is an ideal option for general monitoring in pharmaceutical, healthcare and food production industries.

 

The ImpactAir-90-HF High Flow Portable Monitor – this high flow option is ideal for those wishing to sample air in a much shorter time period or where large volume air samples are required.
