Sample Containers

Measurements will only be performed on samples in ‘standard cuvettes', or wrapped in aluminium foil ‘packets’ so as to be suitable for mounting on the OffSpec sample changer. In the latter case, the samples must be between 12 and 16 mm in diameter (or equivalent squares).

Samples that do not conform to these requirements will be not be measured.

Quartz Cuvettes

Up to 10mm pathlength

Only one type of quartz cuvette (Hellma stock sode 110-QS, Optiglass stock code 21/Q) will be mounted for Xpress Access measurements. If the user requesting access already has appropriate cuvettes they may use them, subject to a maximum pathlength of 10 mm. If not, arrangements must be made with the local ISIS contact for the provision of suitable cuvettes and may be requested from the Xpress online proposal system. No guarantee is made that suitable cuvettes will be available.

Please note: each 'can request' will result in a box of 2 cuvettes being shipped. You may not request or hold more than 4 cuvettes (2 boxes) at any one time.

Loaded cuvettes shall be sealed appropriately by the User and will not be opened at ISIS. Only packaging supplied by ISIS shall be used for sample shipment even where the User is supplying their own cuvettes. Packaging may be requested from the Xpress Request Web site. Loaded cuvettes must not under any circumstances be sent through the normal postal system.

Transport Packaging

Sample containers will be sent to you in UN approved packaging. This packaging comprises a polypropylene inner carton and a fibreboard outer box. It is designed for shipping Packing Group I (one) materials (the most hazardous). Samples such as Lithium Nitride and Sodium Hydride fall into this category.

Your sample must be returned in this packaging using the most appropriate method – Courier or Specialist shipper. Samples may not be sent using the Royal Mail or ParcelForce.

Safety and Shipping

Recent changes in the Transport of Dangerous Goods regulations and the UN ADR document mean that even small scientific samples may need to be classified as Dangerous Goods, and consequently may need to be shipped in a special way. Your dispatch department should be able to help you with this, or see the web site for your chosen courier:

United Nations web site: 

Also remember to enclose a completed Shipping Declaration. The forms below must be printed in colour.

Fedex-specific Shipping Declaration

IATA Generic Shipping Declaration

Samples will be returned to you once any induced activity has reduced to background levels.
