Embodiment
Technical scheme is further illustrated with reference to the accompanying drawings and examples.
With reference to shown in Fig. 1 to Fig. 5, a kind of precision glass volumetric apparatus provided by the present invention, the present embodiment is with 1000ml
Exemplified by the Glass capacity vessel of capacity, related size is also the Glass capacity vessel setting with 1000ml capacity, according to difference
The Glass capacity vessel of amount of capacity, related size are also made to be adapted adjustment setting.Including main bottle body 1, main bottle body 1 includes bottom
Seat 101 and main pipeline 102, the lower end of main pipeline 102 are connected with base 101, and main pipeline 102 is provided with graticule 2, graticule 2
Scale is 1000ml, and liquid volume scale when being 20 DEG C of normal temperature, above-mentioned is prior art part, is just repeated no more herein.With
Unlike prior art, in addition to the first capillary 3, the outer diameter D of the first capillary 3 are arranged to 5mm, and internal diameter d is arranged to
3mm, the first capillary 3 include measuring section 301 and linkage section 302, and measuring section 301 is located at the side of main pipeline 102, and and main pipeline
102 are set in parallel, and the lower end of measuring section 301 is connected with base 101, the upper end of measuring section 301 and one end of linkage section 302
Be connected, the other end of linkage section 302 is connected with main pipeline 102, and with the shape of main pipeline 102 x1, angle x1 in an angle
Angle be arranged to 50 °, measuring section 301 is provided with fine gauge 301a, and different class are indicated beside fine gauge 301a
Temperature value (- 45 DEG C of 0-5-10- ...), and the scale of the constant volume liquid corresponding with each grade of temperature value, every 5 DEG C of temperature value
For a rough segmentation degree, there is the subdivision degree of 5 deciles in a rough segmentation degree, be constant volume under real time temperature corresponding to fine gauge 301a
The liquid level of liquid should where position, so as to the liquid needed for accurate constant volume.
Preferably, also including the second capillary 4, the second capillary 4 is consistent with the profile of the first capillary 3, and with first mao
Tubule 3 is symmetrical set, and is connected at the opposite side of main pipeline 102, also shape between the upper end of the second capillary 4 and main pipeline
