Abstract

The utility model discloses a water quality test sampler. The water quality test sampler is characterized in that a rubber plug is plugged at the mouth of a vacuum flask, one end of a sampling pipe is provided with a feed needle, a protecting cover is sleeved on the feed needle, and a meshed feed port is arranged at the other end of the sampling pipe. With the adoption of the arrangement, the water quality test sampler is simple in structure and convenient to use, can effectively prevent the water from being polluted when medical departments and environmental protection departments perform water quality sampling, and ensures the sterile operation requirement in the whole sampling process, thus the accuracy of the test result is improved.

Description

The water examination sampling thief

Technical field

The utility model relates to a kind of a kind of water examination sampling apparatus that uses in medical sector, environmental administration, is a kind of water examination sampling thief of checking Microorganism in Water specifically.

Background technology

The water quality microorganism detection aseptic technique requires strict especially, sampling thief is the special container that a kind of health and epidemic prevention, environmental administration are used for doing water examination, and have more singularity with the water quality sampling thief that quality testing tests of making a living, that is exactly aseptic, pollution-free, more to all to guarantee sterile working from sampling, censorship, the whole flow process of check, avoid water sample to pollute.Traditional sampling is to utilize vacuum machine that sample container is vacuumized, and connects aseptic water pipe and samples to sample water.Have plenty of directly can of manual operations, cause easily water pollution, cause testing result inaccurate.

Summary of the invention

The purpose of this utility model is the water examination sampling thief that provides a kind of simple in structure, easy to use.

To achieve these goals, the utility model is plugged with rubber stopper at the bottleneck of Dewar bottle, is provided with sample introduction needle at an end of sampling pipe, at the sample introduction needle cover protective jacket is arranged, and netted injection port is located at the other end of sampling pipe.

By above setting, the utility model is simple in structure, and is easy to use, can effectively prevent medical sector, environmental administration when carrying out water quality sampling to the pollution of water, guaranteed the sterile working requirement in the whole sampling process, improved the accuracy of testing result.
