Welcome to our Winter 2014/15 eNewsletter - providing you with the latest news and updates from Cherwell Laboratories. Any additional information that you may require is simply a click away.

However, we are as always, still very happy to speak to you in person and over the phone on 01869 355500.


Continued Developments in 2015

Supporting customer needs

Previous market research affirmed our position as a leading prepared media supplier and we were pleased to be valued for our flexibility of supply, reliability and efficiency in customer relations. Last year we consolidated this position with the completion of our Redipor® prepared media facility expansion, so ensuring that we continue to deliver the quality products, service and support you value.

Also, with customer needs in mind, last autumn we added a new bio-decontamination range to our portfolio. Mar Cor® cleanroom decontamination products fully complement our sterilisation process validation products, enabling us to offer you a comprehensive solution.

Staying abreast of the latest industry updates is essential to ensure we are fulfilling customer expectations now and in the future. So, we will continue our support of industry events in 2015, where we are always very pleased to catch up and hear your feedback too.

We wish you every success in 2015 and look forward to supporting you in this.

Parenteral Sterility Assurance

Critical environmental monitoring

2015 has started with a heightened awareness of sterility assurance for parenteral medicines. This has always been the main focus of interest for Cherwell and all our customers in manufacturing and compounding.

Last year, stories on contaminated parenteral medicines hit the headlines, whilst regulators in the UK, Europe and the USA have all increased their vigilance and demand for diligence in this area. So, it should be no surprise that three conference/training events in January and February share this theme and extend it into non-steriles:

SMI Pharmaceutical Microbiology

PHSS Sterilisation, Sanitisation & Disinfection

Pharmig PCT - Contamination Control & Microbiological Risk Assessment

We fully support PHSS and Pharmig with membership and sponsorship of selected meetings and all microbiologists with an interest in environmental monitoring. Our Sales Manager also recently contributed to a guest blog for EPM Magazine on monitoring cleanrooms and reducing environmental risk.

Christmas Charity

Thank you!

Cherwell staff recently raised £224 in their 2014 Christmas raffle. A huge thank you to everyone who contributed to the raffle through donations of prizes and buying tickets. This amount has been boosted by Cherwell up to £1500, to share between three charities nominated by Cherwell staff - Cancer Research UK, Oxfam's Ebola Fund and Dementia UK.

We already have fund raising plans for a number of worthy causes this year, so please do keep an eye out on our Charity pages for further information.

Ask Cherwell!

Should I rotate cleanroom disinfectants?

Not necessarily, but it might be best practice in most situations as many disinfectants leave a residue which needs to be removed.

Alcohols leave no dry residue, but might encourage the formation of spores resistant to alcohol. Chlorine-based disinfectants tend to be corrosive and leave a residue, but will kill spores with sufficient contact time. Hydrogen peroxide alone, or with peracetic acid, kills spores and leaves no dry residue but is relatively expensive and the vapour has limits for operator exposure. So, rotation with intermittent use of sporicide might enable the most effective bio-decontamination at reasonable cost.

If there’s anything that you’d like to ask us, we’d be happy to help. Just Ask Cherwell.
