Description

Volumetric flask rack

Technical Field

The utility model relates to an experimental facilities technical field specifically is a volumetric flask rack.

Background

When the heavy metal element analysis test in food is carried out, volumetric flasks with different volumes such as 10mL, 25mL, 50mL and the like are needed to dilute the standard solution or the sample solution to a constant volume. Typically, sample solutions are prepared in multiple batches and in parallel, thus requiring the use of large volumes of flasks. At present, most laboratories use plastic baskets, plastic basins or enamel trays to hold volumetric flasks, and laboratory personnel place the volumetric flasks on the table top for operation. Due to the light weight and long neck of the volumetric flask, the volumetric flask can be poured carelessly, so that the solution in the flask is lost or the flask body is damaged. The specification of current commercialization "capacity bottleholder" is fixed, and the connection of undetachable moreover is using and when accomodating comparatively occupation space, has great breach simultaneously at fixed capacity bottle bottleneck position, and the capacity bottle still will be emptyd.

As an optimized scheme of volumetric flask rack, wherein: the top end of the side plate is provided with a handle.

As an optimized scheme of volumetric flask rack, wherein: a plurality of T type draw-in groove has been seted up to two curb plate opposite faces, the equal fixedly connected with T type inserted block of upper plate, median plate and bottom plate both sides terminal surface, T type inserted block and T type draw-in groove sliding connection.

As a preferred scheme of volumetric flask rack, wherein: the side plates, the upper plate, the middle plate and the bottom plate are all made of organic glass or polypropylene materials.

As a preferred scheme of volumetric flask rack, wherein: the upper plate and the middle plate form a forty-five degree included angle, and the middle plate and the bottom plate are horizontally arranged.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the utility model discloses adopt sliding connection's mode between well top plate, well plywood and bottom plate and the curb plate, the convenient dismantlement to the demand of the volumetric flask of different volumes has been satisfied.

2. The utility model discloses well first through-hole is the rectangle through-hole, has made things convenient for getting of volumetric flask to put and has avoided the condition that the volumetric flask slope liquid flows.
