Miniature automatic liquid sampler

Abstract

The invention discloses a miniature automatic liquid sampler, which consists of a timing device, a miniature sampling pump, a sample division bottle, a sample distribution mechanism and a sample receiving disc. The timing device is connected with the miniature sampling pump; the outlet of the miniature sampling pump is connected with the inlet of the sample division bottle; the outlet of the sample division bottle is connected with the inlet of the sample distribution mechanism; and the outlet of the sample distribution mechanism is connected with the sample receiving disc. The invention can automatically and correctly collect the liquid samples at different moments in order, ensures little disturbance during washing and little sample waste, enables small-volume sampling and miniaturization, and can be widely applied to the research field.

Description

Technical field: [0001] The invention relates to a liquid sampling device, in particular to a miniature automatic liquid sampler capable of sampling in small volumes and automatically and sequentially and accurately collecting liquid samples at different times. Background technique: [0002] At present, all kinds of samplers sold in the market are foreign products, which are bulky, complicated to operate, and expensive. Its sampling pump can automatically extract and evacuate liquid, and the flow control accuracy is high. However, the price is expensive, a large amount of liquid is collected during sampling, and the disturbance is large when the sampling pipeline is rinsed, so it is not suitable for small volume sampling, especially not suitable for sampling with limited liquid volume. The control system is a computer control system, which is expensive and complicated to operate, and is difficult to popularize. So far, there is no sampler on the market that can automatical...

Problems solved by technology

But the price is expensive, a large amount of liquid will be collected during sampling, and the disturbance will be large when the sampling pipeline is rinsed, so it is not suitable for small volume sampling, especially not suitable for sampling with limited liquid volume

The control system is a computer control system, which is expensive and complicated to operate, and difficult to popularize

So far, there is no sampler in the market that can automatically and accurately collect liquid samples at different times, miniaturization, less disturbance during rinsing, less sample waste, small volume sampling, low cost, simple operation, stable and reliable sampler
