![]() ![]() Support members are used to maintain the relative spacing between the tubulation and the sample chamber. The sample chamber further includes a resin containing chamber, an ultra high vacuum valve and tubulation to provide access to the resin into the sample chamber. A sample holder can be introduced in to a sample chamber. 4,745,771 discloses a sample holder for the cryo-preparation of biological tissue samples. The bag is then lowered into the specimen chamber. ![]() Vials containing samples can be introduced into a cartridge, which is placed in a bag. ![]() The dewar vessel has an inner vessel that holds a specimen chamber. US 2002/0084277 discloses a shipping container holding a dewar vessel. Another problem that may occur is that with a plurality of vials (or Falcon tubes), it may not be straightforward to trace each sample. This may mean that more dewars or larger dewars need to be used. Each vial (or Falcon tube) occupies a space that is much larger than a cryo-grid storage box, and a dewar may fill up quickly when using a plurality of vials. Although this may be a practical way to store a smaller number of cryo-grid storage boxes, problems can arise when a larger number of cryo-grid storage boxes needs to be stored for a prolonged period of time. Such a vial or Falcon tube is then stored in a dewar for example using a thin cord. Normally, a cryo-grid storage box is introduced into an adapted vial or container such as for example a so-called Falcon tube. biological) samples stay frozen during storage. These cryo-grid storage boxes are then stored in dewars containing liquid nitrogen, so as to make sure the (e.g. It is known to use cryo-grid storage boxes that include a plurality of cryo-grids. If samples cannot be safely stored and/or may degrade at room-temperature or at around 4 degrees, the samples and the corresponding cryo-grids may need to be stored under cryogenic conditions. It may be necessary to store a plurality of these cryo-grids for a short or longer period of time before they can be investigated. Eventually, such a cryo-grid is positioned in an electron microscope to investigate the sample. Such samples may be quickly flash-frozen using liquid ethane. Generally copper cryo-grids are used, in which a 3-4 microliter sample may be deposited. In the field of cryo-electron microscopy, frozen samples are investigated using an electron microscope. ![]()
