We provide a comprehensive pharmaceutical and biopharma DS and DP release testing service to support you in ensuring the identity, purity, stability and quality of your products. Please contact us for details.
The long term stability of drug products (and other healthcare related products) is key to its quality, efficacy, safety and commercialisation. The stability of a product can be assessed in many ways e.g. physical stability (e.g. tablet crumbling, precipitation, viscosity), chemical (e.g. API degradation) or microbiological.
It is therefore vital to carry out stability studies that conform to ICH requirements and that challenge your prototypes and products in a range of environments.
Stability Storage
Our pharmaceutical stability services include a range of monitored temperature, humidity, and light stability storage cabinets which comply with ICH Guidelines, covering requirements for climatic zones I to IV.
Our stability storage conditions:

Whether you require storage only, or in combination with in-house analytical testing, we can tailor our stability service to meet your needs.
Stability Testing
We have a vast range of analytical techniques under the general banners of chemical, microbiological and physical testing that can be used to assess the stability of your product and its packaging in accordance with GMP requirements. We have experience in the development of pharmaceutical stability indicating methods, including photostability and other stress conditions. From protocol preparation to the issue of final reports, we offer comprehensive project management, plus advice and support.
Identification, isolation and purification of process related impurities can be critical to the development and manufacture of pharmaceutical products. Our technical specialist’s expertise in chromatographic and spectroscopic techniques can support with the isolation and identification of impurities from pharmaceutical products or active pharmaceutical ingredients (APIs). Preparative scale isolation is carried out using techniques including preparative liquid chromatography HPLC. Advanced spectroscopic techniques can then be used to identify the impurities of interest, these include nuclear magnetic resonance spectroscopy (NMR; 400Mhz)), mass spectrometry (MS; see LC-MS section for more details) and Fourier transform infra-red spectroscopy (FTIR). Once the impurity has been identified, we can also offer further scale-up for the isolation of larger quantities of impurities for use as reference materials. We are able to scale-up customer specific methods or develop reproducible extraction and purification methods for your products and API’s.

Extractable and leachable (E&L) testing and analysis is critical in maintaining the quality of your drug product or combination drug delivery device. As part of the drug development and route to market, it is vital to identify both the substance and source of any leachable as they may significantly alter the identity, strength or quality of the drug, risking patient safety. There are a number of analyses which must be performed in order to comply with regulatory guidelines, and we can assist throughout with extractable and leachable testing:
In the first instance, an extractable profile needs to be determined for all materials which will come into contact with your drug product. Once it has been determined whether any extractables in this profile are present as leachable within the product, you also need support in quantifying amounts and establishing the biological risk based on exposure. Analytical support can be during all stages of this process. E&L testing has been performed on a wide variety of containers, closures and medical combination drug delivery devices using state-of-the-art equipment and expertise.
The following instrumentation is used for the E&L studies:
LC-MS

We perform real-time stability and shelf-life testing of ingredients and finished products to support you with food product development, claims substantiation testing and troubleshooting.
Assessing stability over shelf-life is a crucial stage in new food product development and reformulation. You need to ensure that your product maintains its characteristic flavour, texture, structural and chemical features throughout the length of its stated shelf-life.
We provide stability and shelf-life testing for raw ingredients and finished food products under a range of conditions, ensuring that you have full understanding of product changes and behaviour over time. We measure changes over shelf life for components such as sweeteners, preservatives, colours, fats, oils, and vitamins, looking at texture, rheology and more. We can also support you with food analysis and testing (including fats and oils testing) to ensure any claim you make about your product can be substantiated over its entire shelf-life for food product development and reformation.
For fats and oils testing and for finished products containing them, we provide an accelerated oxidative stability testing service using Rancimat and Oxipres equipment. Accelerated testing allows you to narrow down potential formulations to the most promising for real-time testing, and to assess the impact of different processing conditions on stability. Your food product development timescale is therefore shortened with our lipid analysis and lipid testing capability, leaving a quicker route to market. Our NPD consultancy has the knowledge to support you with your new product development process.
