Description
Technical field:
The present invention relates to the glass measurement instrument used a kind of assay laboratory, relate in particular to a kind of measuring bottle and using method thereof for the preparation of volatility standard liquid.
Background technology:
At present, the laboratory is when preparation volatility standard liquid, and employed solute and solvent in most cases have volatility.In process for preparation, volumetric flask adds solute and solvent under uncovered state, because solute and solvent have volatility, can cause the continuous volatilization of solute and solvent in operating process, thereby cause the concentration of standard solution of preparation inaccurate.
Chinese patent 200710021281 has provided a kind of for volatility titer preparation, special-purpose measuring bottle and the using method thereof of stocking, and it is made up of screw cap, silica gel sealing pad, T type silica gel sealing plug, volumetric flask.Its using method is:
After choosing the volumetric flask of respective volume, with the bottleneck of T type silica gel sealing plug plug at volumetric flask, in the ratio requirement according to predetermined compound concentration, each component is prepared in the liquid injection capacity bottle as transfer tool with syringe, method for implanting is: the micro-sampling pin of syringe is passed T type silica gel sealing plug, draw respectively with syringe in the preparation liquid and injection capacity bottle of various components, prepare and screw with threaded cap immediately after qualified, can store.When need using the volatility titer in the volumetric flask, the screw cap of outwarding winding, the silica gel sealing pad leaves bottleneck with screw cap, and T type silica gel sealing plug is still filled in the bottleneck at volumetric flask, the pin of syringe is passed T type silica gel sealing plug draw mark liquid in the volumetric flask.
Its shortcoming is mainly as follows:
The accuracy of standard liquid preparation is the basis that standard liquid stores, foregoing invention only seals at the capacity bottleneck with T type silica gel sealing padding when preparing standard solution, if the plug that assurance T type silica gel sealing pad can be firm need have enough silicon gel part to fill in the capacity bottleneck at the capacity bottleneck.When the standard liquid in the capacity is shaken up, need volumetric flask be inverted according to the strictness operation, attention then, repeatedly for several times, could be with the standard liquid mixing.And the permeability of part volatility organic solution is stronger, and the space between T type silica gel sealing pad and the volumetric flask wall may cause part organic solution to be infiltrated, thereby causes the concentration of standard solution prepared inaccurate.
During preparing standard solution, when syringe is extracted from T type silica gel sealing pad, since T type silica gel sealing pad and volumetric flask fix and all to realize by the tension force of T type silica gel sealing pad bottom, when extracting syringe, in order to guarantee that T type silica gel sealing pad is not pulled out, need pin T type silica gel sealing pad with hand, and then syringe is extracted, increase the inconvenience of operating process.If T type silica gel sealing pad might be extracted from the volumetric flask mouth because of carelessness in the operation, all that has been achieved is spoiled thereby cause seal operation.
Therefore when preparing standard solution, rely on T type silica gel sealing pad to seal merely and have certain defective.
In its using method " the micro-sampling pin of syringe is passed T type silica gel sealing plug, draw respectively with syringe in the preparation liquid and injection capacity bottle of various components, prepare screw with threaded cap immediately after qualified ".The using method statement is indeterminate, not the process of sake of clarity standard liquid preparation.In this process for preparation, except adding solute, also need to add the solvent constant volume.As if earlier solute being punctured in the T type silica gel sealing pad injection capacity bottle with micro syringe, puncture T type silica gel sealing pad with syringe then solvent is injected in the bottle, then because the excessive interior malleation of volumetric flask that causes of the volume of solvent is excessive, can't inject.If earlier certain solvent is injected in the bottle, build T type silica gel sealing pad then, puncture T type silica gel sealing pad with in the solute injection capacity bottle with syringe again, when the solute volume that injects is big, may can't inject because the excessive interior malleation of volumetric flask that causes of the solute volume that injects is excessive.
Draw in the method for standard liquid and " when needing to use the volatility titer in the volumetric flask; decontrol screw cap; the silica gel sealing pad leaves bottleneck with screw cap, and T type silica gel sealing plug is still filled in the bottleneck at volumetric flask, the pin of syringe to be passed T type silica gel sealing plug draw mark liquid in the volumetric flask." in the method, if when drawing the solution of large volume with syringe, then since in the volumetric flask negative pressure excessive, cause normally sucking-off of solution.
Summary of the invention:
In order effectively to address the above problem, the invention provides a kind of measuring bottle and using method thereof for the preparation of volatility standard liquid.Measuring bottle of the present invention can prevent the volatilization of solute in the volatility standard liquid process for preparation, thereby guarantee the accuracy of preparing standard solution, and solved the malleation and the negative pressure problem that exist in the volumetric flask in solution preparation and the suction process, guaranteed that solution can easily inject and draw in standard liquid preparation and the suction process.
