Please be aware our sample submission process has changed.

For all projects, we request that you obtain a proposal from our Customer Services team before sending your samples. This ensures that both parties are clear on the scope of the project, analysis required, the agreed turnaround time and associated costs.

A proposal will be generated from our Customer Relationship Management (CRM) giving you a unique identifier.

If you are unsure what analysis you require, please contact the Customer Services team on +44 (0)118 918 4076 or email enquiries@rssl.com.

    Packaging Your Samples

    • Samples should be packaged according to the nature of any associated hazards and in compliance with current legislation. 
    • Ensure that your samples are adequately packed and labelled.
    • Place relevant information on the outside of the box.

    You can find further information regarding the same packaging of toxic and hazardous substances below:


    Hazardous and toxic materials must be packaged as follows:

    • The outer and inner packaging should clearly state that the content is hazardous and the nature of the hazard e.g. cytotoxic, flammable, etc. It is a legal requirement that the carrier of goods and the recipient know the nature of any hazard in the event of an accidental spillage.
    • The outer packaging should contain the name of the person for whom the samples are intended (or the department) – to minimise any unnecessary contact with the samples.
    • Sharp objects should be packed in a rigid container or other suitable packing to prevent any injury to staff (eg. double wrapped - in bubble wrap and in a sealable bag).

    Please be aware that failure to comply with our guidelines may result in the loss/damage of your test sample, delays in agreed turnaround times or additional costs being incurred.

    Paperwork Required

    This information must be accessible within the package in a separate envelope to the samples and thus is accessible before the samples are opened. Refer to REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for more information regarding regulations.

    Always include the sample submission form and complete all fields including details of the analysis required.


  • Pharmaceutical & Other

    PLEASE NOTE - if the appropriate paperwork is not received with the samples this may delay the start of any project work until it is provided.

    Hazardous or Toxic Samples

    1. Always include the COSHH assessment and Safety Data Sheet (SDS/MSDS) for your samples. If you already have a completed COSHH assessment, then please send this. If not, then please complete the COSHH assessment form. Include any information regarding exposure limits or patient safety data.  
    2. If the material is biological in nature, you must include a letter of inactivation signed by a QP, or data to prove that the material is safe to handle by our analysts.

    To ensure the safety of all members of RSSL, any sample which is not correctly packaged, labelled and without the required sample submission or safety information, then this WILL NOT be accepted and will result in delays in agreed turnaround times.

    Thank you in advance for your cooperation and support in complying with our procedures.
