Background technology
Extensively applying burette at present in experimental analysis, cleaning has the burette of greasy dirt to be a difficult problem.Conventional cleaning has oil
The method of dirty burette is: being saved in reagent bottle by chromic acid lotion, operator directly pours burette into the solution of reagent bottle
In.Because the bore of burette is smaller, so chromic acid lotion can splash outside burette, under corrosion skin and clothes, or corrosion
Waterpipe, operator is difficult to control to pouring volume, if greasy dirt is serious, needs repeatable operation, time-consumingly.At present, also the most clear on market
Wash the equipment of greasy dirt burette.
Utility model content
This utility model is for deficiency, it is provided that a kind of.
The technical scheme that this utility model solves above-mentioned technical problem is as follows:
A kind of titration can washing apparatus, including the fixing reagent bottle being located on work top and iron stand, and is located at work
Make the waste liquid bottle of table top side-lower；The gas that upper seal at described reagent bottle is provided with fluid connection tube, band glue head blows up a balloon
Connecting tube and the liquid injection port of with closure；One end of described fluid connection tube is goed deep in reagent bottle under the liquid level of chromic acid lotion, separately
One end be lean out work top vertically downward, with the tip of the hold-doun nut that can fasten the burette mouth of pipe；Described gas is even
The opening of adapter is positioned at the ullage of reagent bottle chromic acid lotion；Described iron stand is provided with and can clamp fluid connection tube
The fixation clamp first of end and the fixation clamp second that burette can be clamped.
Compared with prior art, the beneficial effects of the utility model are: equipment is simple, and common laboratory just can be installed
And use.The process safety of washing burette is reliable, be prevented effectively from chromic acid lotion splash corrode outside burette skin, clothes or under
Waterpipe, pouring volume is easily controlled, easy to operate, is widely used.
On the basis of technique scheme, this utility model can also do following improvement.
Further, described fluid connection tube is provided with rubber seal plug with the junction of reagent bottle.
Above-mentioned further scheme is used to provide the benefit that: to increase the sealing of reagent bottle.
Further, the gas connection pipe below described glue head blows up a balloon is provided with flow control valve.
Use above-mentioned further scheme to provide the benefit that: pouring volume, cleaning speed are easily controlled, save chromic acid and wash
The safety of operation is improve while liquid.
