Description
Technical field
The present invention relates to safe clean bench technical field, is specially a kind of safe clean bench of bioorganism.
Background technology
Biology is a class of natural science.Study the structure, function, the rule of occurrence and development of biology.And
Biology and the science of the relation of surrounding environment etc..Biology is derived from natural history, experienced experimental biology, molecular biology and into
Systems biology period is entered.This noun of biology was proposed by French naturalist's Lamarch in 1802 earliest.Exist in recent years
Under Recent advances in molecular biology leap, using common language of the nucleic acid between species, inquire into scope and remove organism in itself, further include biology
Body and environment, psychology etc. field, become a comprehensive science.
Experimental biology refers to the method for biology is divided into the past the method compared and two major class of method of experiment
(particularly from 19th-century to earlier 1900s), experimental biology is then as the equivalent of comparative biology in this case
.Alone various measurement devices use physics, chemical method, just apply in a physiologically a long time ago, but with life
The analysis of thing phenomenon becomes mainstream for the experimental biology of target, after occurring from 1880, and the foundation of embryo's mechanism
It is exactly the specific manifestation of this respect.The foundation of experimental genetics, is to start from late nineteenth century by the approach application of physiology to something lost
Pass to come up, and by experiment printed words hat before science of heredity, to represent its meaning.
The research project of experimental biology covering has very much, including research and the research of some medicines to biology,
, it is necessary to use sterile, dustless, clean safe clean bench during progress bioorganism research.
The existing safe clean bench for bioorganism generally includes an operation rack, and is set in operation rack
There is work box, the bottom of work box is provided with workbench, and the side of work box is both provided with transparent glass, the front of work box
Operation window is provided with, the equipment such as air cleaning unit and ultraviolet lamp are provided with the top of work box so that in work box all the time
Can have cleaning air flow through so that experimental situation can ensure it is sterile, dustless, with ensure experiment accuracy.
But there are following defect for the existing safe clean bench for bioorganism：
(1) existing safe clean bench is able to ensure that the experimental situation of bacteria-and dust-free in sealing, but in opening operation
When window is tested, the air for having a large amount of dirts enters work box so that experiment is affected；
(2) existing safe clean bench is in order to facilitate observation experiment object, it will usually by the side wall and operation window of work box
Door is arranged to transparent glass, but some experiments need to carry out under the dark surrounds of unglazed or low illumination so that carries out these
, it is necessary to be covered from the external world by glass during experiment, bother very much and shaded effect is bad, influence experimental result；
(3) existing safe clean bench will can be expelled directly out by the air of workbench, but the quality of these air has
May be not worse than the quality of outside air so that these somewhat clean air are wasted, and increase air cleaning unit
Burden.
The content of the invention
In order to overcome the shortcomings of prior art, the present invention provides a kind of safe clean bench of bioorganism, the device energy
