Embodiment 1
[0039] The following will refer to Figure 1 to Figure 6 Embodiments of the delivery device of the present invention are described.
[0040] It should be noted that the transfer device of the present invention refers to a device for transferring samples in two different environments, for example, transferring samples between a general indoor environment and a specific environment. A specific environment, for example, requires a specific temperature, air pressure, and cleanliness. The transfer device provided by the present invention can realize rapid and pollution-free transfer, thereby preventing damage to the sample or the environment caused by the transfer of the sample between different environments.
[0041] The specific structure of the transfer device of the present invention enables the operation of sample transfer to be performed more quickly and efficiently, so that the present invention is particularly suitable for the pollution-free transfer of frozen samples, such ...

The invention provides a conveying device and a pollution-free experimental system comprising the same, which are suitable for conveying and experimenting frozen samples. The conveying device comprises a first assembly which comprises a through hole and a locking part communicated with the through hole and is used for carrying the specified sample; the second assembly is provided with a lock tongue part, and the lock tongue part is embedded in the locking part; and the rod piece is inserted into the through hole, and a locking structure is formed between the locking part and the spring bolt part. By means of the structural arrangement that the notch part of the rod locking piece, the spring bolt part of the locking piece and the locking part of the first assembly are mutually matched in structure and multiple assemblies are cooperatively locked, a more optimized locking matching structure can be achieved, and more effective locking matching can be achieved; and quicker and pollution-free sample conveying or transferring in a frozen sample experiment can be realized.
Description
technical field [0001] The invention relates to the field of conveying equipment, in particular to a pollution-free conveying device and a pollution-free experimental system including the conveying device, which is particularly suitable for the pollution-free transmission of frozen fixed samples. Background technique [0002] Cryofixation is a frequently used sample preparation method in electron microscopy. In this method, the sample containing water is very rapidly frozen (cryofixed) to a temperature of -150°C or below, that is, the sample is cooled very rapidly while avoiding the formation of ice crystals. The above-mentioned cryofixation technique is especially suitable for structural biology research. In addition, the advantage of cryofixation is that the biological structure remains in its native state. In the prior art, a layer of cells, enzymes, viruses or lipid molecules has been implanted into a vitrified thin ice layer to achieve the effect of freezing and fixat...
