Embodiment 1

[0031] An experimental cup for flow-through toxicology experiments of miniature model organisms, which is used for flowing-water toxicology experiments of miniature model experimental animals such as Daphnia magna in medicinal liquid toxicology experiments, and can also be used for breeding and holding miniature daphnia and other micro-sized animals. experimental animals.

[0032] Such as Figure 1-3 As shown, the experimental cup 1 includes a cup body, a cup mouth 1-3, a water inlet hole 1-1 and a clearance hole 1-2. The cup body is a quartz glass cup body with an open design, which is convenient for real-time observation of the state of the large daphnia in the cup. The mouth 1-3 of the cup is in the shape of a small trumpet, which is convenient for taking and placing the cup body. The water inlet hole 1-1 is located on the upper part of the cup wall. On the one hand, it is used as the water inlet of the experimental cup 1. On the other hand, the experimental cup 1 is fixe...

Embodiment 2

[0036] A kind of miniature model organism flowing water type toxicology experiment liquid tank, such as Figure 4-5 As shown, a plurality of experimental cups 1 of the outer cylinder 2 and the embodiment 1 are included. The experimental cup 1 is placed in the outer cylinder 2. Depending on the design of the outer cylinder 2 and the size of the experimental cup 1, several to dozens of experimental cups 1 can be placed in the outer cylinder 2 to achieve large-throughput experiments. .

Abstract

The invention relates to an experimental cup and medical liquid vat for a flow toxicity experiment for miniature model organisms. The experimental cup comprises a cup body, a cup hole and at least onegroup of filtering seam nets, wherein the cup body is a transparent watertight cup body, the cup hole serves as a water inlet, or the water inlet is formed in the cup wall, the filtering seam nets are located at the lower part of the cup wall, each group of the filtering seam nets comprise multiple gap holes formed side by side, and the widths of the gap holes are 0.25mm-0.35mm. The medical liquid vat comprises an outer vat and a plurality of the experimental cups. The experimental cup is easy to clean, medical liquid in the cup is naturally drained, and the cup body is open and transparent,so that a user can conveniently count the number of daphnia magna, and the comparability of an experimental result is improved.

Description

technical field [0001] The invention relates to the field of miniature aquatic model organism breeding, in particular to an experimental cup and a liquid medicine tank for a miniature model organism flowing water toxicology experiment. Background technique [0002] Daphnia grandis is a cladocera invertebrate, yellow or light red, slightly transparent, and the mother Daphnia grandis gives birth to daphnia once every three days. The body length is small, the female body length is 2.2-4.8 mm, and the male body length is 1.75-2.50 mm. It belongs to a tiny aquatic organism. It has the characteristics of short life cycle, fast reproduction, economical, easy to cultivate in the laboratory, very sensitive to changes in various chemical substances in the water environment, and easy to observe changes. As a model organism, it has been widely used in the world. Environmental toxicology and drug toxicity test. This method puts the daphnia magna into the solution containing the tested ...
