The multifunctional vacuum flask is sealed by combining the threaded bottle cap, the silica gel sealing gasket and the T-shaped silica gel sealing plug, so that the vacuum flask can be fully ensured to have no volatility loss in the preparation, storage and use processes of a standard liquid, and the stability of the content of each component in a volatile standard sample is ensured.
Description
Technical field:
The present invention relates to the glass measurement instrument used a kind of assay laboratory, relate in particular to and a kind ofly be used for the preparation of volatility titer, store the glass measurement instrument of usefulness.
Background technology:
At present the assay laboratory is in preparation with to store benzene series, halogenated hydrocarbons, farming residual etc. a series of when relating to poisonous, harmful volatile solvent and mark thing, usually volumetric flask is adopted in preparation, store and then adopt the good sealing performance vial, but in the practical operation application process, still have following defective:
1. when the above-mentioned volatility titer of preparation, volumetric flask must add the mark thing under the state of open ports, because solvent and mark thing are volatile liquid, solvent and the constantly volatilization of mark thing in the process of operation, this just brings two consequences, and the one, volatile poisonous and harmful solvent and mark thing can damage experiment operator health; The 2nd, when preparation mixes the mark thing, must repeatedly open bottle cap, cause the volatilization loss of mark thing, make the mark substrate concentration of preparation inaccurate.
2. because the sealing property of volumetric flask is not good, mark thing liquid must be transferred in other good sealing performance container and store after preparing, and also has devolatilization in transfer process; Can prevent volatilization though use the good sealing performance container to store, but when each the use, still need open the bottle cap sampling, so in use, exist volatile toxic gas that the health hazards of experiment operator and the volatilization loss of mark thing are caused the inaccurate defective of mark substrate concentration equally.
Through applicant's retrieval and investigation, present domestic a kind of desirable glass measurement instrument that do not have as yet, it can effectively solve the problems referred to above that the laboratory runs into when preparing and store the volatility titer.
Summary of the invention:
In order effectively to address the above problem, the object of the present invention is to provide a kind of special-purpose measuring bottle that is used for the preparation of volatility titer, stocks, another purpose provides the using method of this special-purpose measuring bottle.This volatility titer preparation and the special-purpose measuring bottle of stocking of being used for can guarantee that institute prepares the stability of marking thing content, and the toxic and harmful of avoiding again volatilizing is to the Health cost of experiment operator, and easy to use.
Be used for preparation of volatility titer and the special-purpose measuring bottle of stocking, form by screw cap 1, silica gel sealing pad 2, T type silica gel sealing plug 3, volumetric flask 6, the bottleneck that T type silica gel sealing plug 3 is hermetic filled at volumetric flask 6, bottleneck at volumetric flask 6 is provided with external screw thread 4, containing mark line 5 is accurately arranged on the bottle of volumetric flask 6, be convenient to accurate constant volume, silica gel sealing pad 2 is arranged on the inner chamber end face of screw cap 1, and screw cap 1 is tightened on the whorl of bottleneck place of volumetric flask 6.
Preparation and the method for storing the volatility titer: according to the preparation requirement, choose threaded mouthful normal capacity bottle 6 of respective volume, the bottleneck of hermetic filling at volumetric flask 6 with T type silica gel sealing plug 3, ratio requirement according to predetermined compound concentration, with syringe 7 as transfer tool, the pin of syringe 7 is passed T type silica gel sealing plug 3, inject the preparation liquid of various components, prepare and screw and to store with screw cap 1 immediately after qualified to volumetric flask 6.When needing to use the volatility titer in the volumetric flask 6, the screw cap 1 of outwarding winding, silica gel sealing pad 2 leaves bottleneck with screw cap 1, and the bottleneck that T type silica gel sealing plug 3 is still filled at volumetric flask 6 passes the mark liquid that T type silica gel sealing plug 3 is drawn wherein with the pin of syringe 7.
T type silica gel sealing plug 3 in the present invention, silica gel sealing pad 2, screw cap 1 is the key component of whole device, seal bottleneck by it, get mark during thing adding, make volumetric flask 6 internal standard compound liquid be in sealing state, avoid the effusion of volatile toxic and harmful, sealing when sealed silicon rubber cushion 2 main matching thread bottle caps 1 are used for storing at ordinary times, get mark during thing adding, need micro-sampling pin puncture T type silica gel sealing plug 3 with syringe 7, can there be small puncturing hole the puncture back on T type silica gel sealing plug 3, though these micropores meeting auto-closings, but for thorough leakproof, set up silica gel sealing pad 2 between T type silica gel sealing plug 3 and screw cap 1, storage at ordinary times realizes final sealing by silica gel sealing pad 2 and screw cap 1 combination, does not have the slow effusion of gas in the guaranteed capacity bottle.
Owing to set up external screw thread 4 at the bottleneck of volumetric flask 6, add at bottleneck and to have filled in T type silica gel sealing plug 3, in the inner chamber of screw cap 1, be provided with silica gel sealing pad 2, like this in preparation, store, when taking the mark thing, volatility mark thing in the volumetric flask 6 can't be overflowed, it can reduce to greatest extent and has joined the volatilization loss of marking thing in the volumetric flask 6, guarantee preparation result's accuracy, stop the health hazards of volatile substance simultaneously to experiment operator, with screw cap 1, silica gel sealing pad 2 and 3 combinations of T type silica gel sealing plug seal, fully guaranteed capacity bottle 6 is in the preparation of mark liquid, non-volatility loss in storage and the use, the stability of each constituent content in the assurance volatility standard specimen.This special-purpose measuring bottle has preparation and stores two kinds of functions, having realized using one bottle more, the quantity of reduce preparation, storing utensil, in process for preparation, can guarantee join the mark thing accurately, simplified operation sequence, can not produce any injury again, solved the problems that the assay laboratory runs into when preparation and storage volatility titer operating personnel.
