Containers commonly used in laboratories include measuring cups, measuring cylinders, beakers, flasks and the like. The general laboratory student experiment group is more, and the container quantity such as graduated flask, graduated flask is limited, or the capacity is limited, does not satisfy the experimental requirement. The primary problem with this temporary replacement of containers with other containers that do not have graduation marks on their own is how to solve the relative accuracy of the volumetric measurement of the solution in the measuring container. The transparent ruler with scales is usually used for measuring the outer side of the container, but the reading is inaccurate and the error of the result is large due to a certain distance between the inside and the outside of the bottle body; in another method, scale marks are adhered or marked on the outer wall of the container, but the zero point position of the scale marks is not accurately determined, and the observation of the marking line on the outer wall of the container and the liquid level inside the container can generate large errors. There is a need to find a simple method for measuring the volume of solution in a container without graduation marks.

Detailed Description

The following is a solution volume measuring device and method for dyeing and finishing engineering experiments.

Example 1:

a marking method of a reading measurement scale mark of a solution volume measuring device for dyeing and finishing engineering experiments explains that the sizes of a small-mouth solution volumetric flask (8) are respectively 50mm, 75mm, 100mm and 150mm of inner diameter, and the heights of cylinders corresponding to the body of the small-mouth solution volumetric flask (8) are respectively 100mm, 150mm, 200mm and 300 mm.

According to the difference of the size of a small-mouth solution volumetric flask (8), a liquid level reading measurement scale mark (5) is converted with the volume of the solution in advance, and the volume quantity of the solution is directly read out, and the method comprises the following steps:

A. small-bore solution volumetric flask (8) internal diameter 50mm, body cylinder height 100mm, effective volume is in its cylinder height:

(50/2)²x pi × 100, i.e. 196.34ml, with the measurement scale (5) spaced at 100/196.34-0.5093 mm apart, i.e. expressed as 1ml of solution;

B. small-bore solution volumetric flask (8) internal diameter 75mm, body cylinder height 150mm, effective volume is in its cylinder height:

(75/2)²x pi × 150, i.e. 441.79ml, with measurement scale lines (5) spaced 150/441.79-0.3395 mm apart, i.e. expressed as 1ml of solution;

C. small-bore solution volumetric flask (8) internal diameter 100mm, body cylinder height 200mm, effective volume is in its cylinder height: (100/2)²X π × 200, i.e. 1570.80ml, with a measurement scale (5) spacing of 200/1570.80 ═ 0.1273mm, i.e. expressed as 1ml solutionLiquid;

D. small-mouth solution volumetric flask (8) internal diameter 150mm, body cylinder height 300mm, effective volume is in its cylinder height: (150/2)²X pi × 300, i.e. 5301.43ml, with measurement scale lines (5) spaced 300/5301.43-0.0566 mm apart, i.e. expressed as 1ml of solution;

when the above steps are performed, the measurement scale lines (5) may be combined with the pitch lines of the measurement scale lines (5) according to the precision requirement, for example, in step D, 10 pitch lines may be combined into 1 pitch line, that is, the pitch of the measurement scale lines (5) is 0.0566 × 10 to 0.566mm, and each division represents 10ml of the solution.

The plastic transparent measuring tube (4) adopts a thin-wall structure, and the influence on the reading result can be ignored after the large-diameter container is inserted into the liquid level; for containers with higher height and smaller diameter, the correction can be calculated.
