Double-spherical splash-proof ball

Abstract

The invention discloses a double-spherical anti-splash ball, which comprises two hollow spheres, a double-hole pipe, and a ground joint, wherein the two hollow spheres are connected, and the ground joint is arranged on a straight line connecting the centers of the two hollow spheres. The two hollow spheres are connected to the inside of the hollow sphere. There are two grinding ports, which are respectively the grinding port air outlet port and the grinding port air intake port. There are two double-hole pipes, one of which is connected to a ground port The interface connection extends to the inside of the hollow sphere, and the other double-hole tube is connected to another ground interface or the double-ball connection and extends to the inside of the hollow sphere; the double-ball used in the present invention has better explosion-proof and splash-proof effects, even if bumping occurs during rotary evaporation , and double balls can also be used to achieve secondary buffering, reducing the chance of the rotary distilled liquid in the rotary bottle directly flushing into the condensing device and the liquid contact bottle as much as possible, which can effectively prevent bumping and reduce sample contamination.

Description

Technical field [0001] The invention relates to the related technical field of experimental instruments, in particular to a double spherical splash-proof ball. Background technique [0002] Rotary evaporation is a very convenient and practical method for separation, extraction and purification in chemical-related fields such as chemical industry, medicine, biotechnology, and food science. The rotary evaporator mainly uses the basic principle of reduced pressure distillation. Under reduced pressure, the rotary flask continuously rotates, so that the organic solvent forms a thin film in the cavity of the rotary flask, which can effectively increase the evaporation area, continuously and And quickly distill large amounts of volatile solvents. For the concentration of the extract and the distillation of the receiving liquid during chromatographic separation, rotary evaporation can play a role in separating and purifying the reaction product. In the process of rotary evaporation, th...

Problems solved by technology

However, in the case of severe bumping, the existing single-ball rotating explosion-proof ball has poor buffering effect, and the rotary steaming liquid splashed into the single-ball rotating anti-splashing ball is very easy to continue bumping and splash into the liquid receiving bottle
