Multi-row tube cover with liquid separation function

Abstract

The invention discloses a multi-row tube cover with a liquid separation function, and relates to the technical field of reagent tubes. Through one-step sample adding work, a reagent is added into reagent tubes in multiple rows, so that the workload of operators is reduced, and the problems of high working intensity and low working efficiency of operators during large-batch injection are solved. The multi-row tube cover comprises a tube cover body. A liquid separation module and a liquid adding unit communicated with the liquid separation module are arranged in the tube cover body. The liquid separation module comprises a plurality of liquid separation units which are sequentially arranged and communicated with one another. Each liquid separation unit comprises a liquid storage tanks with a centrifugal hole in the bottom, and the tops of the adjacent liquid storage tanks are kept communicated through a micro-fluidic channel. Sample liquid in the liquid separation module is shunted into each reagent tube through centrifugal force, so that an operator is prevented from adding the same reagent into a plurality of reagent tubes, and the workload of the operator is reduced.

Description

technical field [0001] The invention relates to the technical field of reagent tubes, in particular to a multi-row tube cap with liquid separation function. Background technique [0002] Multi-row is a commonly used laboratory consumable. It is a kind of consumable that connects multiple reagent tubes together, which can facilitate the experimenter to take and operate when the experimental workload is heavy. The row is divided into two parts, one part is the tube body and the other is the tube cover. Common multi-rows include eight-rows, 96-well plates, and 384-well plates. [0003] During the experiment, the operator will face the situation of adding the same reagent to multiple reagent tubes. Many commercial detection kits also require the operator to add the same reagent to multiple reagent tubes. It increases the repetitive work of operators, especially in medical institutions and testing institutions. Contents of the invention [0004] In view of the above problems...
