Description

Full-automatic pipettor disinfection device and application method thereof

Technical Field

The invention relates to the technical field of pipettor disinfection, in particular to a full-automatic pipettor disinfection device and a use method thereof.

Background

A pipette, also called a pipette, is a metering tool that removes liquid from an original container into another container over a range of ranges. Is widely used in the fields of biology, chemistry, medical treatment and health. The tools, because of their frequent use for pipetting, require their periodic sterilization, especially in the biomedical field, and removal of nucleic acid contamination. If the disinfection is not in time, cross contamination can be caused in the front and back experiments.

Ozone disinfection technology was invented by the chemical family c.f. schbyen in germany in 1840 and was used in the water treatment disinfection industry in 1856. At present, ozone is widely used in the fields of water treatment, air purification, food processing, medical treatment, medicines, aquaculture and the like, and plays a great promotion role in the development of the industries. Ozone sterilization is a bacteriolytic grade method, has thorough sterilization, no residue and broad sterilization spectrum, can kill bacterial propagules, spores, viruses, fungi and the like, and can destroy botulinum toxin. In addition, ozone has a mold killing effect. Ozone is a pollution-free disinfectant because ozone is poor in stability and can be automatically decomposed into oxygen or single oxygen atoms, and the single oxygen atoms can be automatically combined into oxygen molecules, so that no toxic residues exist. Ozone is gas, can quickly permeate the whole sterilization space, and has no dead angle in sterilization.

The current method for disinfecting and removing nucleic acid pollution mainly comprises the methods of alcohol soaking and wiping, high-pressure sterilization and ultraviolet irradiation. The method has the defects that the method is required to disassemble the liquid dispenser or the liquid dispenser is not thoroughly sterilized and cannot be cleaned in place. The pipettor belongs to precision measurement instrument, and non-professional dismantles troublesome and influences precision. Therefore, a comprehensive and simple disinfection method is necessary.
