The sampler is easy to use, with a simple keypad menu (in a choice of languages) to lead the user through a variety of preset or user-defined functions, including flexible sampling volumes, delayed start, multiple run and variable interval options. It can be operated manually or using an infra-red remote control ideal for monitoring highly sensitive, closed environments.
The Thermo Scientific Air Sampler has been shown to be efficient and reliable, with validation studies demonstrating a physical efficiency of 100% for particles 0.8 to 19.0 microns in size (BS EN ISO 14698-1:2003 Annex B). Once activated, the unit automatically samples air at a fixed rate of 100 litres per minute. Air is drawn through small holes in the sample head and directed onto the surface of an agar plate. A flashing LED shows that sampling is in progress and an audible signal indicates the end of the sampling period. The agar plate is then removed and incubated in order to assess levels of contamination. The Thermo Scientific Air Sampler can accommodate 55mm and 90mm plates and has flexible plate holders which allows for slight variation in plate diameter. The unit is supplied with a 90mm sampling head as standard, with a 55mm sampling head available as an optional accessory.
Sample details (e.g. date, time, location, sampled volume and operator ID) are stored within the unit. This information is easily accessed and visualised on the alpha-numeric display or can be printed via a standard printer cable. It is also possible for data to be downloaded to a computer (using the Thermo Scientific Air Sampler Software CD) for reporting and trend analysis.
The Thermo Scientific Air Sampler is supplied fully calibrated with a calibration certificate traceable to recognised Standards. Furthermore, the sample head can be changed, or removed for cleaning, quickly and easily without the need for recalibration. Calibration is recommended at six to twelve monthly intervals after purchase, Thermo Scientific has a calibration service available to do this. Advice and support is provided by the fully trained Thermo Scientific Technical Support Team.
Ali Ball, marketing & distributor sales director, commented, "The new Thermo Scientific Air Sampler complements the wide range of high quality environmental monitoring products available from Thermo Scientific. It is our aim to provide customers with everything that they need to ensure the microbiological quality and safety of their products and services."
Thermo Scientific provides a full range of suitable pre-poured culture plates for use with the Thermo Scientific Air Sampler, including Tryptone Soya Agar and Sabouraud Dextrose Agar in 90mm and 55mm contact plate formats. These can be supplied irradiated and/or triple wrapped (including VHP impermeable packaging) as required.
