Abstract

The invention discloses a kind of method that Rotary Evaporators ball milling mouth condenser pipe can be converted to straight mouth condenser pipe.The present invention utilizes a kind of device that rotary evaporator ball milling mouth condenser pipe is converted to straight mouth condenser pipe, simple structure, convenient operation, saves lab space, is easy to operation, time saving and energy saving, saves economical.Rotary Evaporators ball milling mouth condenser pipe can be converted to rapidly straight mouth condenser pipe, the loss shifted when avoiding concentrate secondary concentration by this method, improves extraction efficiency.

Description

A kind of footpath that turns that ball milling mouth condenser pipe can be converted to straight mouth condenser pipe is managed
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.
This device mainly consists of the following components: (1) fixed projection: be positioned at and turn on the pipe of footpath, is mainly used in assisting stainless steel clip fixedly to turn footpath pipe and lower end receiving flask, makes it does not fall and ensure air-tightness; (2) turn footpath pipe: upper end, this part and the seamless connection of condenser pipe ball milling mouth, lower end to insert in ground receiving flask and ensures air-tightness, meets the demand of follow-up decompression;
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 is 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.
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.
Detailed description of the invention
The embodiment of this patent:
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 evaporator is opened vavuum pump button after being connected respectively with straight mouth Rotary Evaporators and started to vacuumize, can see that vavuum pump instrument board display 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, receiving flask is inserted in lower end, and receiving flask stainless steel clip is fixed on fixed projection.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 ground condenser pipe, time saving and energy saving, and save space.

Claims (1)

1. one kind for being converted to the method for straight mouth condenser pipe by rotary evaporator ball milling mouth condenser pipe, it is characterized in that used device comprises fixed projection and turns footpath pipe, fixed projection is positioned at and turns on the pipe of footpath, footpath pipe and lower end ground 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 ball milling mouth condenser pipe ball milling mouth, lower end to insert in ground receiving flask and ensures air-tightness, turn pipe lower end, footpath and the seamless connection of ground receiving flask and reach the requirement that can meet and reduce pressure when Rotary Evaporators works, 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 ground receiving flask fix, make it does not fall and ensure air-tightness, fixed projection plays the effect fixedly turning footpath pipe by stainless steel clip.
