Description
Technical field
The utility model, about experiment rack for test tube, is specifically related to a kind of rack for test tube cleared up for nitrogen phosphorus.
Background technology
In the water that " water and waste water method for monitoring and analyzing " (the 4th edition) relates to and waste water, total phosphorus yield needs to carry out pretreatment to water sample, preprocess method conventional in laboratory is digest by potassium persulfate, concrete operation step described in this book is: draw 25.0ml and mix water sample if desired, take the circumstances into consideration water sampling less, and add water to 25ml, phosphorus content is made to be no more than 30ug in 50ml tool plug graded tube, add potassium persulfate solution 4ml, mouth of pipe bag one fritter gauze after jumping a queue also is tightened with line, in order to avoid glass stopper is gone out during heating.Tool plug graded tube is placed in large beaker, is placed in autoclave or pressure cooker heats, treat that pot inner pressure reaches 1.1kg/cm
2time (relevant temperature is 120 DEG C), after regulating furnace temperature to make this pressure of maintenance 30min, stop heating, after gauge hand is down to zero, taking-up lets cool.As solutions turbid, then use Filter paper filtering, constant volume after washing.
The assay method of the water that " water and waste water method for monitoring and analyzing " (the 4th edition) relates to and Determination of Total Nitrogen in Waste Water has potassium persulfate oxidation-ultraviolet spectrophotometry and gas molecule in space absorption spectrometry, two kinds of methods all need water sample to put into color-comparison tube, add constant volume after alkaline chitinase, close plug, bottle stopper is wrapped with gauze and yarn rope, in case splash out, then colorimetric cylinder is put into High pressure steam sterilizer and clear up.
From the above, all need to clear up to the mensuration of total phosphorus, total nitrogen in water and waste water, before clearing up, need the bottle stopper wrapping color-comparison tube with gauze and yarn rope, in order to avoid glass stopper is gone out during heating.Conventional rack for test tube is the wooden or bamboo shelf in 6 holes and 12 holes, without any other parts, so just make experimenter spend the plenty of time to be carried out one by one by the test tube on rack for test tube shaking up and use gauze and yarn rope bottle stopper to be wrapped clear up water sample, clear up after also need test tube to put back to rack for test tube one by one in order.As can be seen here, for the mensuration of total phosphorus, total nitrogen in water and waste water, conventional rack for test tube complex operation and a large amount of time can be wasted, and gauze and yarn rope need often to change.
Through finding the literature search of prior art, if CN201210366462.6 is a kind of Multifunctional test tube shelf, rack for test tube flexible adjustment in this invention, be convenient to rack for test tube grafting each other, solve that existing rack for test tube structure is fixed, can not be regulated, storage capacity is little, the shortcoming of function singleness to a certain extent; ZL201120562088.8 is a kind of device being elevated upset rack for test tube, device in this utility model solves the trouble that test tube need be overturn one by one, laboratory technician can be made to reduce by the working time of 20 times, and the distance with sterilamp can be reduced when carrying out sterilamp irradiation by hoisting depth, high degree add exposure intensity, improve sterilizing efficiency; ZL201320479509.X is a kind of rack for test tube, this rack for test tube when testing can placing height higher than its test tube, can also the low test tube of placing height, collect folding for rack for test tube after finishing experiment, greatly can save space, conveniently to store; CN201410060580.3 is a kind of rack for test tube with locking function, this rack for test tube can be widely used in test tube transport, deposit and in other operating process, ensured the security of test tube.But the full inconvenience of above-mentioned rack for test tube of the prior art is used for total phosphorus, the clearing up of total nitrogen.
