Description

Technical Field

[0002] 96-well plates are commonly used experimental consumables and can be used for cell culture and storage. During the experiment, in order to prevent liquid spillage, sample contamination, sample loss and other problems in the 96-well plate, the 96-well plate needs to be sealed with film, which involves sealing and cutting the film. The heat sealing film sealing machine is used. If the temperature is low, the 96-well plate will not be sealed tightly, and if the temperature is high, the film will be easily damaged. If the temperature is heated unevenly, some wells of the 96-well plate will not be sealed tightly. In addition, if the film transported to the top of the 96-well plate is not tensioned, the wells will also not be sealed tightly.

[0003] Based on the above defects and deficiencies, it is necessary to improve the existing technology and design a 96-well plate automatic film sealing machine. Utility Model Content
