See instructions by topic below. Click topic to see details. A submission form must be included with every sample.

How do I choose the sampling container?

  1. Select the sample containers according to the nature of the material.
  2. Use clean fresh polyethylene bag for solid materials.
  3. Use clean and dry glass bottle or stoppered flask for solvents and liquids.

How do I choose the sampling device?

For Solids/powders:
Use clean disposable spatula or clean stainless-steel spatula designed for solid materials.

For liquids:
For the liquid, use specially designed sampling container.

Sampling instructions:

  1. Clean the sampling device first with water/alcohol and wipe it a with lint free wipe.
  2. Assign sampling to the Chemist authorized for sampling of materials.
  3. Check the details of the material receiving note and enter the details on the sample submission as required.
  4. Label the sample bag/sample container with the necessary information, the sample name, lot number, date sampled and any additional information as required.
  5. Seal the bag/container properly and submit to the testing lab as per approved specifications under supervision.

What to do when you find out the sample/container is damaged?

  1. Check the physical condition and cleanliness of the material to be sampled before opening.

Shipping instructions

Reliability directly contributes to fast turnaround times

The shipping and storage conditions are extremely important, when compromised, clients need to send additional samples and, ultimately, result in a longer turnaround time because testing cannot commence until new samples are received.

Key factors come into play when transporting samples:


Packaging is often at the discretion of the client. However, Chemists and technicians at Nutrasynth can guide clients in how to package their samples to protect both the sample and those who might be handling the samples. 

Storage conditions

Depending on the nature of the sample and the temperatures to be stored the samples are to be transported. Samples which should be stored at temperatures between 2-8 Degree Celsius should be shipped with the ice packs in the shipping box to maintain the required temperatures.

Receiving procedures

Clients should complete a mandatory sample submission form, which includes information about how their samples need to be stored. The samples are received only on the working days (Monday -Friday). We prefer to have samples sent on a Saturday, Monday, Tuesday, or Wednesday so samples get sent to us and we receive them Monday through Friday.


Safety is a vital aspect of sample transfer. If we receive samples that are leaking or compromised, we will notify the client to ensure they take proper precautions.

We recommend our clients to submit Safety Data Sheets (SDS) for liquid, powder, and drug-containing samples. There are two main reasons for this. First, so that we are aware of the materials we work with during testing and can take the proper safety precautions. It also gives us the information we need to safely handle samples should they become damaged or leak.
