Sample size & representative sampling: The amount of sample required will vary depending upon the material type and the
testing to be performed. Samples should be representative of the material being tested. A composite sample prepared from
multiple collections within a container or multiple production lots is a better representation than a single isolated collection.
For some purposes, the sample must be collected following a specific sampling plan. To determine the amount to submit for
testing, please call or email. We’re here to help.
Sample identification and labeling: Samples must be clearly identified and the identification must match accompanying
documents. Apply well-secured labels with permanent, non-smudging, water-stable ink. The identification must remain
legible throughout the process of shipping and handling.
Containers for samples: Leak-proof, durable containers must be used, with each sample container placed in a sealed plastic
bag. Even sample types that have a dry appearance can lose or gain moisture or other volatile components. For most sample
types and most analyses, the best type of container is usually a high-density polyethylene bottle with a screw-capped
closure. Special sampling bags may be used for many non-liquid sample types if they are well-sealed and double-bagged. For
certain tests, specific sampling containers are required. To determine what type of container is appropriate for your needs,
please call or email.
Shipping containers: For samples that must be cooled, a styrofoam cooler inside a corrugated box is usually adequate.
Regulations specified by carriers regarding shipping containers and types of materials that may be shipped via their service.
If the samples are frozen or perishable, dry ice may be needed. Dry ice can make plastic brittle, so some insulation, such as
layers of paper or cardboard, should be placed between dry ice and sample containers. Some sample types and some
analyses may require the use of blue ice instead of dry ice. For questions, please call or email.
Hazard identification: Anything that may leak from a package causes great concern to carriers. Dry ice must be declared on
the shipping form, and there is a limit established by the carrier for the amount of dry ice shipped. Do not ship hazardous
materials without prior written consent and without appropriate packaging and labeling. All applicable laws governing
transfer of hazardous materials must be followed.
Shipping methods: Perishable samples or samples that may change, including the loss of volatiles, should be shipped
overnight with prior notification. Afternoon delivery is sufficient for many sample types, depending on the material and the
analyte. Shipping dates should be selected so that samples are not left in transit over a weekend. When needed, Saturday
delivery can be scheduled. Ship to the physical address: 11291 Harmony Road, Carthage, MO 64836.
