・ Used to measure a certain volume. It is also called a full amount flask.
・ The slender neck is stretched on a flat flask at the bottom, and there is usually one line on the neck.
・ Because the diameter of the scale of the scale is narrow, the scale accuracy is higher than the same capacity female cylinder.
・ It is used to accurately adjust a certain reagent concentration.
・ The scale represents the acceptance volume (the volume in), and the TC that means reception (input) is displayed. (TC: to content abbreviated)
・ The scale represents the volume when water at 20 ° C is measured.
・ Compliance with the "permissive error of volume" of JIS Standards (R3505) class A.
・ Tea dyed outside is applied to the outside for shading.

● Precautions for using female flask
Put the paper between the plugs and the female flask when storing, as the plug may be chewed and does not come off.
In addition, it is often said that heating and drying is "the scale goes crazy", but there is no problem with general heating drying. In the manufacturing process, white prints and silver stains are burned at a high temperature of 500 ° C or more after hitting the scale. A literature that examines "whether heating affects the scale of the glass bodies" has been announced. However, please note that when heating and drying. It can be damaged by a thermal impact. It is recommended that you put the freshly washed device in the lower row, as the freshly washed volume gemstore is put in the upper row of the heated and dryer, depending on the temperature, depending on the temperature difference from the dropped drops, it may be damaged. increase. When using a heated dryer, pay attention to the setting temperature and how to put the glass equipment.
