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.

Having troubles submitting your samples? Please contact us. We’re always happy to help.

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 Eppendorf tubes

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

  • Use screwcap tubes
    Screwcap tubes are the safest tubes to ship your precious sample, as it is less likely the lid will open. If you do not have screwcaps; close the tubes tightly, and seal the tubes by tightly wrapping parafilm around the individual tubes.
  • Check if your tubes are closed well
    Always make sure all the tubes are properly closed. Tubes may open during rough transport, especially when lids are not fully closed.
  • Mark your tubes
    Be careful with markers, especially when transporting cells in methanol, as the ink can be washed away by the methanol. Therefore please mark your tubes on top AND on the side. Write clearly and with a suitable cryomarker. Printing your labels is preferred, with specialized cryo labels, but we understand that not everyone has access to such labels and printers. Be careful with tough spots, as the normal tough spots will release from the tubes at extreme cold. You can think about making a picture of the tubes once they are ready for shipment. This way you have a backup for the labeling in case the ink washes away during the shipping.
  • Secure the tubes well within the package
    Use a cardboard Eppendorf box (plastic is not flexible enough) with insert, to protect the tubes during rough transport. Make sure the box is upright and not on its side, and that it has a lid.
  • Do not use a shipping box that is too large
    The larger the shipping box, the more space the Eppendorf box with the tubes has to be jostled around. If you do not have a smaller shipping box, try to “lock” the Eppendorf box in the middle by putting empty tip boxes, or something similar around it.
  • Put the tubes at the bottom of the package: dry ice evaporates over time. It might seem that the Eppendorf box with tubes is well secured within the dry ice when you pack it, but if the box is at the top of the package it will start moving around once some dry ice has evaporated and it gets more space. Try to start the package with a small layer of dry ice. Put the Eppendorf box 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 Eppendorf box. This way the box with the samples will only start moving around when a lot of dry ice has evaporated.
  • All tubes that are packed need to be submitted
    Any duplicate/triplicate or control samples also need to be recorded within the sample submission form. You can add in the comments whether these tubes should be processed or not. If the tubes are not submitted online, our lab staff won’t know how to handle them.
