[Cherwell’s new Redipor® TwistLock plates](https://www.cherwell-labs.co.uk/redipor-twistlock-prepared-media) feature a secure locking lid and side-label with a GS1 DataMatrix barcode to enhance contamination protection, improve traceability and support automation to ensuring [environmental monitoring](https://www.cherwell-labs.co.uk/cleanroom-environmental-monitoring) (EM) meets exacting industry standards.  The addition of Redipor TwistLock plate options alongside standard plates in Cherwell’s broad range of [Redipor prepared media products](https://www.cherwell-labs.co.uk/prepared-media), supports a shift in pharmaceutical and associated industries towards more standardised, traceable, and risk-based microbial EM. The new locking lid plates  -  which are also available globally within [AnalytiChem’s Redipor portfolio](https://www.analytichem.com/products/redipor), align with [GMP Annex 1](https://www.cherwell-labs.co.uk/eu-gmp-and-annex-1-the-new-version) and ICH Q9 principles, offering benefits in terms of [contamination control,](https://www.cherwell-labs.co.uk/cherwell-labs-post/cherwell-locking-plates-contamination-control-strategy) regulatory compliance, and operational resilience. Sample security is ensured by the secure seal on the plate enabled by TwistLock technology, preventing contamination and protecting sample integrity when transporting within and between facilities. Designed to deliver data integrity and reliability, Redipor TwistLock plates maintain the highest standards of data accuracy and traceability supported by GS1 barcodes on side-labels. They also support automated colony counting, plus integration with LIMS and electronic batch records. Additionally, the plates’ user-friendly design aids laboratory workflow efficiencies as they streamline handling, reduce errors and minimise costly retesting.  [![New Call-to-action](https://no-cache.hubspot.com/cta/default/2885977/d1a9d97e-c3ae-46e2-b72c-112a9c347d06.png)](https://cta-redirect.hubspot.com/cta/redirect/2885977/d1a9d97e-c3ae-46e2-b72c-112a9c347d06) Like Cherwell’s standard Redipor prepared media plates, Redipor TwistLock plates are available triple-wrapped and gamma irradiated in Petri and contact plate formats to guarantee sterility and extend shelf-life to six months. Bespoke options are also available - a key offering of Cherwell’s Redipor range is the ability to customise to user needs in terms of differing media formulations, fill volumes and packaging formats. As the UK prepared media manufacturing site for AnalytiChem, Cherwell is ensuring security of  local supply to the pharmaceutical and medical manufacturing market. Expanding direct supply globally, within the Analytichem global group, Redipor TwistLock plates will also be manufactured in the U.S. and mainland Europe, in the Netherlands. This gives manufacturers choice in plated media for sampling when EM protocols may require use of locking lid plates as an alternative to standard plates. “As a trusted supplier to the pharmaceutical and medical manufacturing industry we are always endeavouring to best understand our customers’ needs and flexibly offer the products that fit their requirements – including bespoke options,” said Yoggya De Silva, Microbiology Product Specialist, Cherwell. “Meeting Annex 1 and other key regulatory requirements by ensuring data integrity and reducing contamination risk in sterile product manufacturing processes is one such key need. The launch of our new locking lid Redipor TwistLock prepared media plates, provides an answer to the demand for ever-increasing vigilance, and building resilient and reliable microbial EM programmes.” 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.
