Description

Technical Field

[0001] The present application relates to the technical field of concentrators, and in particular to a high-throughput vacuum parallel concentrator. Background Art

[0002] The concentration step is an indispensable step in the pre-treatment process of laboratories in various industries. The vacuum parallel concentrator uses centrifugal force, heating and the vacuum provided by an external vacuum pump to evaporate the solvent. It can process multiple samples at the same time without causing cross contamination.

[0003] After searching, the Chinese patent authorization announcement number CN217187914U discloses a high-throughput vacuum parallel concentrator, including a base, a circular oscillator is fixedly installed on the top of the base, a water bath is fixedly installed on the output end of the circular oscillator, and the water bath is internally hinged with one end extending to a door above the water bath.

[0004] A high-throughput vacuum parallel concentrator in the above patent has the following deficiencies: the device places the concentration cup on the placement rack, and while closing the box door, the box door presses the connecting rod to move on the guide block, presses the cross plate, and drives the placement rack to move downward as a whole, thereby completing the installation of the concentration cup. Although it can also play the role of moving the concentration cup downward, the device often needs to close the box door to complete the downward movement, and when the concentration cup moves downward, the reset spring is in a compressed state, so the box door itself must have a certain weight, which is not particularly convenient when opening the box door, and the spring on the device will quickly experience metal fatigue after repeated compression and reset for a long time, and has a short service life. It also needs to be replaced, which is more troublesome. Utility Model Content
