Abstract
The invention discloses a diameter converting pipe capable of converting a ball-mill-hole condenser pipe of a rotary evaporator into a straight-hole condenser pipe. The diameter converting pipe comprises a glass diameter converting pipe which is externally provided with a fixed protrusion. The diameter converting pipe is simple in structure, convenient to operate, saves the space of a laboratory, easy to be operated, saves both time and force, and is economic. With the adoption of the diameter converting pipe, the ball-mill-hole condenser pipe of the rotary evaporator can be quickly converted into the straight-hole condenser pipe, so that the loss caused by converting at the secondary concentration of concentrate can be avoided, and the extracting efficiency is raised.
Description
Technical field
Patent of the present invention relates to a kind of experimental facilities conversion equipment, in the time of can using Rotary Evaporators for laboratory, the condenser pipe of ball milling mouth is converted to straight mouthful of formula condenser pipe, is convenient to experimental implementation.
Background technology
Rotary Evaporators is mainly used in a large amount of effumability solvents of continuous still under reduced pressure, in the process of the experiments such as organic pollution mensuration, plays a very important role, be organic pollution extract important step.From in the various organic pollution materials entered environment media of the industries such as agricultural, chemical industry (water body, soil, vegetation etc.), through effects such as a series of physics, chemical conversion and biological utilisations, be adsorbed in various surrounding mediums.Under dynamics and biological agent or when environment changes, material strippings such as the toxic organic pollutant being rich in surrounding medium or suspend again, and then enter overlying water, and by vegetation or fish, enter in food chain, health is produced to greatly harm.Therefore, in research environment medium, various toxic organic pollutant environmental pollutions are administered and protect health most important.
In order to measure toxic organic pollutant in surrounding medium, utilize Rotary Evaporators concentrating sample just particularly important.But in actual experiment process, sometimes to need to use the condenser pipe of ball milling mouth, sometimes in order testing, need to need again to select the condenser pipe of straight mouthful, and the conversion between two kinds of condenser pipes not only to be wasted time and energy but also waste economical.Therefore, we have designed a kind of footpath that turns that ball milling mouth condenser pipe can be converted to straight mouthful of condenser pipe and have managed, simple and convenient.
Summary of the invention
Originally turn footpath pipe and Rotary Evaporators ball milling mouth condenser pipe can be converted to straight mouthful of condenser pipe, guarantee the sealing of sample when concentrated, and simple and convenient, reduced the trouble of purchasing the economic loss of two cover condenser pipes and having avoided condenser pipe dismounting refitting, save time, improve thickening efficiency, liquid transfer indfficiency while avoiding secondary concentration.
This device mainly consists of the following components: (1) fixed projection: be positioned at and turn footpath pipe above, be mainly used in assisting stainless steel clip fixedly to turn Guan He lower end, footpath receiving flask, make it does not fall and guarantee air-tightness; (2) turn footpath pipe: upper end, this part and the seamless connection of condenser pipe ball milling mouth, lower end inserts in ground receiving flask and guarantees air-tightness, meets the demand of follow-up decompression;
The use procedure of this device is: when in experiment, wish is converted to straight mouthful of condenser pipe by rotary evaporator ball milling shape of the mouth as one speaks condenser pipe, only need to turn pipe upper end, footpath and condenser pipe ground joins, coat appropriate vaseline, with clip, fix, insert in receiving flask lower end, and be fixed on projection and receiving flask bottleneck with stainless steel clip.So, ground condenser pipe can be converted to straight mouthful.
The feature of this conversion equipment is: turn footpath pipe volume little, can guarantee under the bubble-tight prerequisite of condenser pipe, ground type condenser pipe is converted to the straight shape of the mouth as one speaks, transfer process is simply efficient, and the loss of having shifted while having avoided concentrate secondary concentration improves extraction efficiency, only with one, turn footpath pipe and just can save lab space, easy operating, time saving and energy saving, save economical.Patent of the present invention meets the requirement of sample concentration, to guarantee accuracy and the science of sample analysis the data obtained.
Accompanying drawing explanation
Accompanying drawing 1 turns the structural map of footpath pipe for glass.Reference numeral: 1: fixed projection; 2: glass turns footpath pipe.
The specific embodiment
The embodiment of this patent:
1 Rotary Evaporators decompression test
In order to verify practical applicability of the present invention, choose and originally turn footpath bobbin to Shanghai the reduce pressure test contrast of prompt RE-52AA type Rotary Evaporators of shaking.
Specific implementation process: 1, ball milling mouth condenser pipe rotary evaporator is opened vavuum pump button after being connected respectively with a straight mouthful of Rotary Evaporators and started to vacuumize, can see that vavuum pump instrument board shows that vacuum rotary evaporator interior condenser tube vacuum raises rapidly, can reach 1000.2, turn footpath pipe contrast test: will turn pipe upper end, footpath and be connected with condenser pipe ball milling mouth, stainless steel clip is fixed, and receiving flask is inserted in lower end, and receiving flask is fixed on fixed projection with stainless steel clip.Open vavuum pump, can find that vacuum rises rapidly, can reach 1000, prove that turning footpath pipe can reach good air-tightness, meets requirement of experiment.
It is detection index that the vacuum in organic concentrated experiment is selected in this research.Because some target compound evaporation loss very easily in organic concentrated experiment, need to control target compound by controlling vacuum.Utilize former Rotary Evaporators (ball milling mouth and straight mouth) and install the evaporimeter difference extracting vacuum that turns footpath pipe additional, adopting Patent equipment extracting vacuum of the present invention and two kinds of original-pack Rotary Evaporators all can reach 1000 vacuums.The result of contrast test shows, adopts the Rotary Evaporators that originally turns footpath pipe can reach rapidly 1000 vacuums.And in laboratory, one of a need turns footpath pipe just can be converted to ball milling mouth condenser pipe straight ground condenser pipe, time saving and energy saving, and saves space.
Claims (4)
1. one kind for being converted to rotary evaporator ball milling mouth condenser pipe in the device of straight mouthful condenser pipe, comprise fixed projection and turn footpath pipe, it is characterized in that: fixed projection is positioned at and turns on the pipe of footpath, be used for assisting stainless steel clip fixedly to turn Guan He lower end, footpath receiving flask, make it does not fall and guarantee air-tightness, turn pipe upper end, footpath and the seamless connection of condenser pipe ball milling mouth, lower end inserts in ground receiving flask and guarantees air-tightness, meet the demand of follow-up decompression, a stainless steel clip is for turning the fixing of footpath pipe and ball milling mouth condenser pipe, another stainless steel clip is for turning the fixing of footpath pipe and receiving flask, make it does not fall and guarantee air-tightness.
2. device according to claim 1, turn pipe upper end, footpath can with the seamless connection of ball milling mouth condenser pipe.
3. device according to claim 1, turns pipe lower end, footpath and can and reach with ground boiling flask, the seamless connection of heart bottle the requirement of reducing pressure in the time of meeting Rotary Evaporators work.
4. device according to claim 1, fixed projection can play the effect that fixedly turns footpath pipe by stainless steel clip, is difficult for dropping after making it to connect ground boiling flask, heart bottle.
