Description
Technical field
The utility model relates to experimental apparatus technical field, and particularly a kind of accurate control concentrates the concentrating instrument of volume.
Background technology
Concentrating instrument is mainly used in the concentrated of the extract sample containing organic solvent, concentrated principle is after the steam volatilized in extract sample hose rises to condenser pipe, meet condensation and form drop, discharge after the tube wall landing of condenser pipe, extract sample constantly evaporates until reach setting volume.
The pick-up unit that concentrating instrument of the prior art uses accurately can not detect the liquid level of concentrating sample, causes the target volume error of final concentrating sample larger.
Utility model content
For solving the problem, the utility model provides a kind of terminal liquid level that concentrating sample accurately can be detected, and automatically stops the accurate control of concentration process to concentrate the concentrating instrument of volume.
A kind of accurate control that the utility model provides concentrates the concentrating instrument of volume, comprising: pedestal, flow generator, jacket condensator, water bath and sample tube; Described water bath is fixed in described pedestal; Described sample tube is placed in described water bath; Described jacket condensator is fixed on the top of described sample tube; Described flow generator is fixed on the top of described jacket condensator, and described concentrating instrument comprises:
Photoelectric sensor, is horizontally set on described pedestal; Described sample tube is provided with terminal liquid level line; Light emission mouth and the described terminal liquid level line of described photoelectric sensor are positioned at sustained height;
Data collecting card, is connected with described photoelectric sensor by logical circuit;
Acquisition controller, is electrically connected with described data collecting card; Described acquisition controller is communicated with the operating circuit of described flow generator.
As preferably, described sample tube is the cylindrical tube of bottom undergauge; Described terminal liquid level line is arranged on the bottom of described sample tube.
As preferably, described concentrating instrument comprises two photoelectric sensors; Described sample tube is provided with two described terminal liquid level lines;
