Abstract

The invention discloses a pressure-maintaining transfer and culture device for a deep sea water sample. The pressure-maintaining transfer and culture device mainly comprises a pressure-maintaining sampling barrel, a transfer and culture barrel, a first high-pressure pump, a second high-pressure pump, a third high-pressure pump, an overflow valve and the like. The device can realize pressure-maintaining transfer of the deep sea water sample after deep sea water sampling, and can carry out later-stage culture experiment on the transferred water sample. The system adopts a unique structure design to realize the equal-pressure equal-temperature transfer technology of the sample; the post-treatment technology can keep states such as a high-pressure water sample gas phase, an organic phase and osmophilic organisms, is beneficial for keeping the original components and properties of the sample, reduces the discrimination effect on follow-up lab post-treatment and is of great importance on authenticity and reliability of sample detected data. Moreover, the device can add a culture solution needed for an experiment into a culture cavity without being dismounted in the working process, and is convenient and efficient.

Description

technical field

[0001] The invention relates to a pressure-holding transfer and culture device for deep sea water samples, in particular to a pressure-hold transfer system for deep sea water samples after deep sea water sampling, which can perform post-stage culture experiments on the transferred water samples. Background technique

[0002] With the advancement of human exploration of the ocean, there are a large number of biological activities and material exchanges in the boundary layer between the seabed sediment and the bottom seawater in the deep seawater. Sampling and analysis of the bottom seawater is helpful for a comprehensive understanding of the complex ecosystem of the seabed. .

[0003] The deep sea water fidelity sampler has formed a complete set of technologies through the development in recent years, and its sampling depth, sampling volume, and pressure holding indicators have repeatedly hit new highs. However, the usual practice in sample transfer is depres...
