Embodiment Construction

[0028] Embodiment 1 of the volumetric flask fixing device of the present invention is as follows when in use figure 1 and figure 2 As shown, the volumetric flask fixing device comprises a bracket, which is provided with a support seat for supporting the volumetric bottle 13 and a top seat for the neck of the volumetric bottle 13 that is spaced apart from the support seat along the vertical direction. A compression seat for compressing the volumetric bottle 13 is also provided between the top seats.

[0029] The bracket includes a base plate 1 and uprights 2 vertically arranged on the base plate 1. There are two uprights 2 and they are arranged symmetrically on the base plate 1. In other embodiments, there may be four uprights 2 and they are arranged on four corner. The base plate 1 is provided with a fixing hole, and the upright column 2 is inserted into the fixing hole on the base plate 1. The upright column 2 and the base plate 1 are fixedly connected by a jacking wire 9,...

Abstract

The invention relates to a volumetric flask fixing device. The volumetric flask fixing device comprises a support; a supporting base for supporting volumetric flasks and a top base for the necks of the volumetric flasks to penetrate through are arranged on the support, and the top base is spaced from the supporting base in the vertical direction; a pressing base for pressing the volumetric flasksis arranged at the position, between the top base and the supporting base, of the support, the pressing base and the supporting base can move relatively, openings for the necks of the volumetric flasks to penetrate through are formed in the pressing base, and the openings have rims applying downward pressure to the volumetric flasks. The pressing base can apply downward pressure to the volumetricflasks through a pressing structure; when the volumetric flasks are immersed into water for ultrasonic treatment, the pressing base makes the volumetric flasks immersed in the water all the time by overcoming buoyancy on the volumetric flasks, so that the floating phenomenon is avoided, and the ultrasonic treatment effect is guranateed.

Description

technical field [0001] The invention relates to a volumetric flask fixing device. Background technique [0002] A volumetric flask is a precise instrument used to accurately prepare a solution of a certain concentration of a substance. When preparing the solution, the volumetric flask is usually ultrasonically treated to accelerate the dissolution of the substance; when the prepared solution is stored at low temperature, some solutes will precipitate due to the drop in temperature, and when used again, in order to redissolve the precipitated solute, Redissolution of the solute is also accelerated by sonication after the volumetric flask containing the solution is removed from the cryogenic refrigerator. [0003] The authorized announcement number is CN206731000U, and the Chinese utility model patent whose authorized announcement date is 2017.12.12 discloses a volumetric flask fixed ultrasonic device. The volumetric flask fixed ultrasonic device includes a bracket. A collar...
