Both of Cherwell's SAS Super Pinocchio units are non-powered air samplers that test the microbiological quality of both compressed air and gases.
The range includes the already popular SAS Super Pinocchio II and the new, more compact, SAS Super Pinocchio CR; which offers a more convenient way to monitor for viable particles in compressed air and other gas supplies. Both can be fully dismantled for easy cleaning. However, the Pinocchio CR is now manufactured in stainless-steel to allow a more effective decontamination process.
Using the proven SAS method of viable air sampling, the Pinocchio air samplers collect air samples onto Contact plates, or 90mm Petri dishes.
Air flow from the compressed supply is regulated through a flow meter before passing through a traditional SAS sampling head.
Both Pinocchio units provide a controlled method for bioburden monitoring of compressed air and other gases and can be included in an environmental monitoring program.
They are ideal for use in manufacturing facilities where compressed air monitoring is falling under increasing regulatory scrutiny.

"Staff are always quick to respond and try to help as much as possible within the scope of their own knowledge/ability. If they are unable to help, they will always forward the query onto someone who can."
Typical requirements suggest 1,000 litres per air sample in high risk areas, such as: grade A filling lines, grade B clean rooms, operating theatres etc. As the criticality of the area reduces, the sample size can be reduced. The aim is to achieve a representative sample; so where higher counts would be expected, a smaller sample produces a more realistic number of cfu to count.
SAS samplers were originally designed for Contact plates, however, a Petri dish option has been available for a number of years. It is really a personal choice, although this should be decided at time of purchase, as the sampler will be specifically configured for the plate type chosen. There are advantages for each version and we would be happy to discuss your specific needs.
No, do not put your SAS sampler in a steam autoclave. The only part that can be autoclaved is the drilled head. The unit can be wiped with alcohol wipes to decontaminate it. The only other exception is the SAS Pinocchio, parts of which can be autoclaved.
Cherwell Laboratories recommends every 12 months and we will send a reminder for the month it is due. For some situations local procedures demand more frequent recalibrations so Cherwell is happy to offer tailored recalibration date labelling and reminders on request.
The sterility of the packaged medium is assured and all but the outer layer of packaging is also sterile. Thus the risk to the environment to be sampled is greatly reduced. There is an additional benefit that the additional packaging and process extends the room temperature shelf life. This can be sufficient reason for small or irregular users to prefer irradiated.
Settle plates are used to monitor the level of viable particles in the environment through a process of passive air sampling. A viable particle settles on agar plates at a rate dependent on its characteristics and the airflow in the environment.
EU GMP Guide Annex 1 has recommended that 90mm settle plates can be exposed in cleanroom environments for up to 4 hours. However, agar plates may dry out during long exposures where the rate of air exchange is high. So, it might be necessary to use deep filled settle plates, or replace the settle plate after a shorter time to ensure satisfactory growth promotion after exposure.
The storage condition for the majority of our prepared media is Ambient not exceeding 25ºC, the exception being a couple of very specialist products.
We have never specified storage in a fridge for our general media as this causes excessive condensation and can result in a very wet agar surface. This makes the product impossible to use.
General purpose media have nutrients that support the growth of most non fastidious culturable microorganisms. Selective growth media contain components that will inhibit the growth of some types of microorganisms, while supporting the growth of others.
General purpose media, such as Tryptone Soya Agar, are used to produce total counts. While selective media, such as XLD for Salmonella species, are used to test presence/absence of specific types of microorganism.
