Description

Portable liquid suction device for super clean bench

Technical Field

The utility model belongs to the technical field of the imbibition device, a portable imbibition device for superclean bench is related to.

Background

The vacuum pump is a common device in biological experiments, and can be used as a liquid absorbing device after being combined with a filter flask and a corresponding pipeline system, and is used for separating solid and liquid components in a sample or separating mutually incompatible liquids in the sample. Although the vacuum liquid suction device for experiments which is sold on the market at present is widely applied to actual operation, the vacuum liquid suction device for experiments still has the defects and the disadvantages, and the defects are as follows:

(1) the equipment volume is great, when using in super clean bench, has excessively taken up desktop space, produces adverse effect to user's operation easily.

(2) Although a high vacuum degree can be achieved, the problem of high operating noise of the vacuum pump is caused, on one hand, communication between users is difficult (loud conversation is needed), on the other hand, unpleasant operating state is easily caused to people, and the vacuum pump is not suitable for long-time use.

(3) The equipment relies on the 220V commercial power socket power supply, to the super clean bench that does not take power source, need let equipment get electric work through the mode that additionally inserts row and insert, perhaps can only install equipment in the external side of cabinet, its practicality greatly reduced. When the device is applied to special working environments such as field sampling, a battery and an inverter must be carried, and the portability is insufficient.

(4) The integrated design is adopted, the maintenance difficulty is high, and equipment is usually required to be helped by professional maintenance personnel or returned to the factory for maintenance when damaged, so that most laboratories have to carry out redundant storage on the system for the occasional needs.

(5) In biological experiments, ultraviolet irradiation is one of the commonly used sterilization methods. Therefore, the ultra-clean bench is generally provided with an ultraviolet sterilizing lamp for eliminating the pollution of the mixed bacteria to the experiment. However, the ultraviolet ray has a big disadvantage of extremely weak penetrability, and the inner space of the conventional integrated vacuum liquid absorption device cannot be directly irradiated by the ultraviolet ray. Therefore, when the ultraviolet lamp is used in the super clean bench, if a user has high requirements on the sterile environment, the ultraviolet lamp must be turned on for a long time, and after enough ozone molecules are generated in the super clean bench and completely permeate into the instrument, the instrument can be effectively sterilized, the process can be as long as several hours, and the ultraviolet lamp is difficult to be applied to temporary experiments with high requirements on timeliness.
