Description
Technical field
The utility model patent relates to a kind of experimental facilities conversion equipment, when may be used for laboratory use Rotary Evaporators, the condenser pipe of ball milling mouth is converted to straight mouth formula condenser pipe, is convenient to experimental implementation.
Background technology
Rotary Evaporators is mainly used in a large amount of effumability solvent of continuous still at reduced pressure conditions, plays a very important role in the process that organic pollution mensuration etc. is tested, 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.), be adsorbed in various surrounding medium through effects such as a series of physics, chemical conversion and biological utilisations.Under dynamics and biological agent or when environment changes, material stripping or the settling flux such as the toxic organic pollutant be rich in surrounding medium, and then enter overlying water, enter in food chain by vegetation or fish, high risks is produced to health.Therefore, in research environment medium, various toxic organic pollutant environmental pollution is administered and protects 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 needing the condenser pipe using ball milling mouth, sometimes need and need to select the condenser pipe of straight mouth to test, and the conversion between two kinds of condenser pipes not only being wasted time and energy but also waste economy.Therefore, we devise a kind of footpath that turns that ball milling mouth condenser pipe can be converted to straight mouth condenser pipe and manage, simple and convenient.
Summary of the invention
This turns footpath pipe can be converted to straight mouth condenser pipe by Rotary Evaporators ball milling mouth condenser pipe, ensure the sealing of sample when concentrated, and it is simple and convenient, decrease the economic loss of purchasing two cover condenser pipes and avoid the trouble of condenser pipe dismounting refitting, save time, improve thickening efficiency, liquid transfer indfficiency when avoiding secondary concentration.
The technical scheme that this device adopts is: comprise fixed projection and turn footpath pipe, it is characterized in that: fixed projection is positioned at and turns on the pipe of footpath, footpath pipe and lower end receiving flask is fixedly turned for assisting stainless steel clip, make it does not fall and ensure air-tightness, turn pipe upper end, footpath and the seamless connection of condenser pipe ball milling mouth, lower end to insert in ground receiving flask and ensures air-tightness, meet the demand of follow-up decompression, stainless steel clip is for turning the fixing of footpath pipe and ball milling mouth condenser pipe, another stainless steel clip for turn footpath pipe and receiving flask fix, make it does not fall and ensure air-tightness.
Further, pipe upper end, footpath and the seamless connection of ball milling mouth condenser pipe is preferably turned.
Further, preferably turn pipe lower end, footpath can with ground boiling flask, heart bottle seamless connection reach the requirement that can meet and reduce pressure when Rotary Evaporators works.
Further, preferred fixed projection plays the effect fixedly turning footpath pipe by stainless steel clip, not easily drops after making it to connect ground boiling flask, heart bottle.
The use procedure of this device is: time in experiment for rotary evaporator ball milling shape of the mouth as one speaks condenser pipe is converted to straight mouth condenser pipe, only need connect turning pipe upper end, footpath with condenser pipe ground, coat appropriate vaseline, fix with clip, lower end is inserted in receiving flask, and be fixed on projection and receiving flask bottleneck with stainless steel clip, so, ground condenser pipe can be converted to straight mouth.
The feature of this conversion equipment is: turn footpath pipe volume little, can under the bubble-tight prerequisite of guarantee 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 shifted when avoiding concentrate secondary concentration improves extraction efficiency, only turn footpath pipe with one and just can save lab space, be easy to operation, time saving and energy saving, save economical.The utility model patent meets the requirement of sample concentration, to ensure accuracy and the science of sample analysis the data obtained.

Detailed description of the invention
The embodiment of the utility model patent:
A kind of device for rotary evaporator ball milling mouth condenser pipe being converted to straight mouth condenser pipe, comprise fixed projection 1 and turn footpath pipe 2, wherein, fixed projection 1 is positioned at and turns on footpath pipe 2, for the ground receiving flask 5 of assisting stainless steel clip 4 fixing glass to turn footpath pipe 2 and lower end, make it does not fall and ensure air-tightness, glass turns footpath pipe 2 upper end and the seamless connection of ball milling mouth condenser pipe 3, lower end to insert in ground receiving flask 5 and ensures air-tightness, meet the demand of follow-up decompression, stainless steel clip 4 turns the fixing of footpath pipe 2 and ball milling mouth condenser pipe 3 for glass, another stainless steel clip 4 turns the fixing of footpath pipe 2 and ground receiving flask 5 for glass, make it does not fall and ensure air-tightness.Glass turns footpath pipe pipe upper end, 2 turns of footpaths and ball milling mouth condenser pipe needs seamless connection, and glass turns footpath pipe 2 lower end can reach the requirement that can meet and reduce pressure when Rotary Evaporators works with ground receiving flask 5 seamless connections such as ground boiling flask, heart bottles, fixed projection 1 plays by stainless steel clip 4 effect that fixing glass turns footpath pipe 2, not easily drops after making it to connect ground boiling flask or heart bottle.
1 Rotary Evaporators decompression test
In order to verify the utility model practical applicability, choose this turn footpath bobbin to Shanghai shake prompt RE-52AA type Rotary Evaporators carry out decompression test contrast.
Specific implementation process:
1, ball milling mouth condenser pipe Rotary Evaporators is opened vavuum pump button after being connected respectively with straight mouth condenser pipe Rotary Evaporators and is started to vacuumize, can see that vavuum pump instrument board display vacuum rotary evaporator interior condenser tube vacuum raises rapidly, can reach 1000.2, footpath pipe contrast test is turned: rotary evaporator ball milling mouth condenser pipe is converted to straight mouth condenser pipe, pipe upper end, footpath will be turned connect with condenser pipe ground, coat appropriate vaseline, fixed projection and ball milling mouth condenser pipe is clamped with stainless steel clip, lower end is inserted in ground receiving flask, and be fixed on projection and receiving flask bottleneck, as shown in Figure of description Fig. 2 with stainless steel clip.Open vavuum pump, can find that vacuum rises rapidly, can reach 1000, prove to turn the air-tightness that footpath pipe can reach good, meet requirement of experiment.
This research selects the vacuum in organic concentrated experiment to be Testing index.Because some target compound very easily evaporation loss in organic concentrated experiment, need to carry out control objectives compound by controlling vacuum.Utilize former Rotary Evaporators (ball milling mouth and straight mouth) and install the evaporimeter extracting vacuum respectively turning footpath pipe additional, adopt the utility model Patent equipment extracting vacuum and two kinds of original-pack Rotary Evaporators all can reach 1000 vacuums.The result display of contrast test, adopts this Rotary Evaporators turning footpath pipe can reach rapidly 1000 vacuums.And in laboratory, only need one to turn footpath pipe and just ball milling mouth condenser pipe can be converted to straight mouth condenser pipe, time saving and energy saving, save space, save economical.
