Submit your samples online

Before you ship your samples or plates, please submit them via our online sample submission form. By doing this, we know that we can expect your samples soon. In addition, the info is required for processing in our lab.

We do not process samples or plates that do not have a completely filled out submission form.

Packing requirements

General requirements

The following is required for every package:

  • Ship samples only at Monday or Tuesday
    To prevent the package from getting stuck over the weekend, please only send your package out on a Monday or Tuesday.
  • Ship samples with sufficient dry ice
    Approximately 2.5-3 kg dry ice per day of shipping is the standard, but with warm temperatures, it is advisable to add more dry ice. In addition, make sure you use a box that is not too big. A large void can cause dry ice to evaporate quicker.
  • Make sure the samples are sufficiently secured
    Unfortunately, it is possible that the package is handled roughly during transit, even with proper warnings on the box. We see this quite often. Please secure the samples so they cannot move around the box too much. For more information about the specific packing of cell capture plates and Eppendorf tubes see below.
  • Add proper documentation to the package
    Please add the excel sheet from the sample submission form to your package, so we can identify the samples quickly and without issues. When the package has to clear customs, we recommend adding a letter to the package with all the information on the contents. In our experience, this usually helps to clear a package (quicker). You can download our customs letter template here.

Packing requirements for cell capture plates

To ensure that plates arrive in good condition, please follow these tips & tricks on top of the general requirements:

  • Seal the plate covers well
    Always make sure the plate covers are sealing the wells of the plate well to prevent the transfer of material from one well to the other during rough transport. Please don’t use plastic seals, as they tend to release from the plates at extreme cold. Only use the aluminium plate seals that were provided with the plate order.
  • Do not use a shipping box that is too large
    The larger the box, the more space the plates have, to be jostled around. If you do not have a smaller shipping box, try to “lock” the plates in place by putting empty tip boxes, or something similar, around them.
  • Secure the cell capture plates well within the package
    • Tape the plates together using (dry ice compatible) tape. Elastic bands don’t work as they become brittle due to the cold temperatures.
    • Never store plates loose in the dry ice. Instead, store the plates together in a standard cardboard Eppendorf box (plastic is not flexible enough) without the insert, or in a plastic (zip-lock) bag.
  • Make sure the plates are placed with the sealed side up
    Please make sure the plates are with the wells down/sealed side up within the package, to ensure that the contents stay at the bottom of the wells.
  • Put the plates at the bottom of the package
    Dry ice evaporates over time. It might seem that the plates are well secured within the dry ice when you pack them, but if the plates are at the top of the package they will start to move around once some dry ice has evaporated and they get more space. Try to start the package with a small layer of dry ice. Put your plates on top of that in the center of the box. Then fill the remainder of the package with dry ice, so dry ice sits on all sides around the plates. This way the plates will only start moving around when a lot of dry ice has evaporated.
