Description

technical field [0001] The invention belongs to the technical field of sampler, in particular to a detachable array sampler. Background technique [0002] With the development and progress of science and technology, people's requirements for things have changed from the old thinking that can be used to become quite delicate and demanding. Only the idea of ​​continuous improvement or innovation will produce new forms to increase the added value of products. , in order to survive under the test of fierce market competition. In various experiments that require pipetting, such as biochemistry, it is often encountered that the distance between the sample when sampling and the distance between the target holes when adding the sample are inconsistent. The single-channel sampler injects samples independently, or the multi-channel sampler is realized by variable pitch; the single-channel sampler has low efficiency and slow speed, and the plunger rod power of the sampler for each cha...

Problems solved by technology

In various experiments that require pipetting, such as biochemistry, it is often encountered that the distance between the sample when sampling and the distance between the target holes when adding the sample are inconsistent. The single-channel sampler is independently sampled, or the multi-channel sampler is realized by variable pitch; the single-channel sampler has low efficiency and slow speed, and the multi-channel variable-pitch sampler has the plunger rod power of each channel Independent configuration is required, and at the same time, a complex variable pitch mechanism is required to realize sampling and adding samples at different intervals, resulting in high cost of multi-channel samplers for sampling and adding samples at different intervals, which in turn leads to high-throughput detection equipment due to variable pitch multi-channel sampling high cost and cannot be widely used
