Rotatable volumetric flask rack and application method

Abstract

The invention discloses a rotatable volumetric flask rack and aims to overcome the defect that a volumetric flask which is reversely arranged is inconvenient to drain, low in draining speed and poor in draining effect. The rotatable volumetric flask rack comprises a chassis and a rotating mechanism mounted on the chassis, wherein the rotating mechanism comprises an upper tray, a lower tray and a rotary sleeve; a support column is arranged on the chassis, the rotary sleeve is rotatably mounted on the support column in a sleeving manner, a rotary vibrating mechanism is mounted between the rotarysleeve and the support column, the upper and lower trays are fixedly mounted on the rotary sleeve, a plurality of upper insertion holes are uniformly formed in the upper tray, a plurality of lower insertion holes are formed in the lower tray and the upper insertion holes in a one-to-one correspondence manner, volumetric flasks which are obliquely and reversely placed are inserted between the upper insertion holes and the lower insertion holes, a rotary disc is rotatably mounted on the rotary sleeve, the outer wall of the rotary disc is arranged obliquely and the outer wall of the volumetric flask is attached to the outer wall of the rotary disc, a plurality of outward protruding friction bars are uniformly arranged on the outer wall of the rotary disc, and the friction bars are obliquelyarranged from top to bottom along the anti-clockwise direction.

Description

technical field [0001] The invention relates to a volumetric flask rack, more specifically, it relates to a rotatable volumetric flask rack and its use method. Background technique [0002] In experimental testing, it is often necessary to use volumetric flasks for operation. Volumetric flasks are reusable as a glass container. When a volumetric flask is used to complete a test, it is necessary to clean the volumetric flask, drain it and store it for the next time. use. Because the volumetric bottle has a large body and a small neck, it will fall and break if it is directly inverted to drain. At present, in order to facilitate the inversion of the volumetric flask, the volumetric flask is often placed upside down on the bottle holder. Although the problem of the volumetric flask toppling can be solved, the draining speed of the volumetric flask is slow and the effect is not good, especially at the bottom of the volumetric flask. Under the action of atmospheric pressure, th...
