Enabling simpler installation within restricted-access barrier systems (RABs) and filling lines, the new isolator head has the same features as the standard SAS sampling head, but it can now be more easily positioned *in situ.* The new SAS Isolator sampling head with tri-clover fitting, which is an industry standard, hygienic fitting, is used in conjunction with the [SAS Super Isolator](https://www.cherwell-labs.co.uk/sas-isolator-sampling). This microbial air sampler offers an accurate, reliable and flexible monitoring solution for isolator cabinets and filling lines.  Using bespoke stainless-steel sampling heads such as the new Tri-Clover version, which are placed permanently inside an isolator cabinet and connected to an externally located control unit, reduces potential contamination risk. These viable particle samplers use standard sieve sampling technology to collect one cubic metre air samples.    [![New call-to-action](https://no-cache.hubspot.com/cta/default/2885977/be8d393e-7063-495a-8ebe-992d6238e31f.png)](https://cta-redirect.hubspot.com/cta/redirect/2885977/be8d393e-7063-495a-8ebe-992d6238e31f) As it uses an industry standard tri-clover (tri-clamp) fitting, the new sampling head provides easy integration within confined spaces, as well as allowing quick and easy removal for service and/or calibration.  It can also be supplied for either Contact plates or Petri dishes, to meet differing customer requirements. The company has been supplying the UK market with the SAS range of microbial air samplers for over 30 years. The range includes a wide selection of [portable hand held units](https://www.cherwell-labs.co.uk/hand-held-microbial-air-samplers), a [compressed air sampling device](https://www.cherwell-labs.co.uk/sas-compressed-air-sampling) and an [isolator specific unit](https://www.cherwell-labs.co.uk/sas-isolator-sampling), all of which provide benefits for specific environmental monitoring purposes. Cherwell has built a reputation within the pharmaceutical and healthcare sciences industry as a provider of high-quality products to meet the specific requirements of environmental monitoring and process validation.  The Cherwell range not only includes air samplers, but also a selection of [environmental monitoring accessories](https://www.cherwell-labs.co.uk/prepared-media-accessories) and a range of [Redipor® prepared media](https://www.cherwell-labs.co.uk/cleanroom-equipment/redipor-prepared-media/poured-plates/), which compromises of a selection of petri dishes, settle plates, [bottled media](https://www.cherwell-labs.co.uk/bottled-media-products), [broth bags](https://www.cherwell-labs.co.uk/broth-bags-and-ampoules), [vials ](https://www.cherwell-labs.co.uk/injection-vials-and-din-bottles)and ampoules.   Comments ## Read other blog articles [ *By Gill Power* #### Specialist products for boosting microbial EM protocol reliability spotlighted by AnalytiChem UK at Pharmig 2025 ](https://www.cherwell-labs.co.uk/cherwell-labs-post/analytichem-uk-highlight-specialist-em-products-pharmig-2025-annual-conference) [ *By Gill Power* #### New AnalytiChem UK appointment strengthens customer focus and growth strategy ](https://www.cherwell-labs.co.uk/cherwell-labs-post/new-analytichem-uk-appointment-strengthens-customer-focus-and-growth-strategy) [ *By Gill Power* #### Cherwell announces Andy Whittard’s retirement and names Stuart Hall as new Managing Director ](https://www.cherwell-labs.co.uk/cherwell-labs-post/cherwell-announces-andy-whittards-retirement-stuart-hall-named-new-managing-director) ### Sign Up for our Blog We promise that we won't SPAM you. #### What's next #### Recent news [![Specialist products for boosting microbial EM protocol reliability spotlighted by AnalytiChem UK at Pharmig 2025](https://www.cherwell-labs.co.uk/hs-fs/hubfs/Redipor%20TwistLock%20Contact%20Plates%20with%20GS1%20DataMatrix%20Codes.png?width=50&height=50&name=Redipor%20TwistLock%20Contact%20Plates%20with%20GS1%20DataMatrix%20Codes.png) **Specialist products for boosting microbial EM protocol reliability spotlighted by AnalytiChem UK at Pharmig 2025** 10 November 2025 ](https://www.cherwell-labs.co.uk/cherwell-labs-post/analytichem-uk-highlight-specialist-em-products-pharmig-2025-annual-conference) [![New AnalytiChem UK appointment strengthens customer focus and growth strategy](https://www.cherwell-labs.co.uk/hs-fs/hubfs/Tom%20Pickford%20AnalytiChem%20UK%20Business%20Development%20Manager%20Midlands.jpg?width=50&height=50&name=Tom%20Pickford%20AnalytiChem%20UK%20Business%20Development%20Manager%20Midlands.jpg) **New AnalytiChem UK appointment strengthens customer focus and growth strategy** 20 October 2025 ](https://www.cherwell-labs.co.uk/cherwell-labs-post/new-analytichem-uk-appointment-strengthens-customer-focus-and-growth-strategy) #### Subscribe Receive the latest articles as they are published. #### Contact us Registered Office 7 & 8 Launton Business Centre, Murdock Road, Bicester, OX26 4XB **Phone** Tel: +44 (0) 1869 355 500 **Email** [sales.uk@analytichem.com](mailto:sales.uk@analytichem.com)    ![analytichem_Logo+claim_RGB](https://www.cherwell-labs.co.uk/hs-fs/hubfs/analytichem_Logo+claim_RGB.png?width=2000&height=431&name=analytichem_Logo+claim_RGB.png "analytichem_Logo+claim_RGB") ![BSI-ISO-9001-Certified-50px](https://www.cherwell-labs.co.uk/hs-fs/hubfs/BSI-ISO-9001-Certified-50px.png?width=130&height=77&name=BSI-ISO-9001-Certified-50px.png "BSI-ISO-9001-Certified-50px") AnalytiChem UK ©2025 (Formerly Cherwell) Reg. in England No: 01159518 VAT Reg.
