Unique solutions for isolator cabinet and production line monitoring
Cherwell’s SAS Super Isolator samplers are a development of our hand-held SAS microbial air samplers, adapted for use in isolator cabinets and cleanroom filling lines. A stainless steel sampling head is placed inside an isolator and connected to an external controller. This reduces the risk of contamination because the sampling head remains inside the cabinet.
Cherwell’s SAS Super Isolator samplers offer unmatched functionality that can be tailored to your specific requirements. Customised, uprated and cross-compatible, they deliver confidence for your cleanroom. But with numerous options available, and huge variation in cleanroom environments and usage scenarios, several factors influence the cost.
Upgrades from the get-go
Cherwell’s engineers customise all Super Isolator samplers as soon as they arrive, to increase ease of use, convenience and functionality. Controllers and heads reach us as pairs, so each head can only be used with its matched controller. This means there’s no cross-compatibility, as using an unpaired head and controller combination can impact the accuracy of results.
We calibrate the units and install a printed circuit board (PCB) inside each sampler head. This enables the fan speed to be set at the head rather than the controller. This might seem a minor point, but it allows controllers and heads to be used interchangeably. A significant advantage: if a controller’s damaged or the battery’s dead, no problem: just use the sampler head with a different controller, without compromising the results. It’s not possible to do this safely without the upgrades we make.
We also uprate the cable connections to more robust specifications, and install a light in every sampler head for clear indication that the unit’s functioning inside the cabinet.
Cables, connections and mounts
For a simple solution, with a single connection from head to controller, the only cost variable will be the length of the cable; a more complex environment will need a more elaborate solution.
Where connections have to be made through walls, more connectors, sockets and cable will be required. If an isolator cabinet is large, it may be necessary to install several samplers, or perhaps double-headed samplers: units with two heads offer the ability to sample air at 360 litres per minute, or simultaneously pass air across different types of prepared media.
Mounting options also have to be considered: do you need a standard base to attach to an isolator head, or a tri-clover bracket for post-mounting, for example? The industry standard tri-clover fitting allows easier installation within restricted-access barrier systems (RABs) and alongside filling lines. This provides easy integration within confined spaces, and allows quick and easy removal for servicing and calibration. Tri-clover post mounts also mean cabling can be hidden within the post, reducing the risk of contamination in production areas.
Super Isolator solutions unique to you
No two environments are the same, but Cherwell offers extremely robust, accurate and versatile Super Isolator systems that represent a reliable, adaptable and cost-effective method of microbial monitoring. We take pride in our ability to offer a solution that’s customised to your specific needs, and any specialist requirements you may have.
The ultimate cost will be dictated by the setup in your facility, and the complexity of the solution required. To discuss these with us, and benefit from all the advantages of Cherwell’s added value Super Isolator samplers, contact our customer support team on +44 (0)1869 355 500.
