Scope

GB/T 44831-2024 is the English-translated version of 皮肤芯片通用技术要求.

GB/T 44831-2024 is the Chinese national standard covering the microfluidic device that grows a skin-like tissue outside the body — the chip and the base materials it is machined from, its micro-channels, valves and reaction chambers, the light transmittance that governs what can be observed through the chip body, the leaktightness that keeps the culture in and everything else out, and the marking, accompanying documents, packaging, transport and storage. The device has to reproduce the barrier structure and function of real skin, so what it is built from and how tightly it seals decide what a result taken on it is worth. First edition. In force from 26 October 2024. Issued on 26 October 2024, it has been in force since 26 October 2024.

3 Terms and Definitions

The terms and definitions defined in GB/T 27990, GB/T 39514 and the following apply to this document.

3.1 microfluidic chip

It is made of silicon, glass, metal materials, polymers and other materials as the base material, and is processed using micro-nano processing, precision injection molding and other processing technologies. biochip.

Note. It includes one or more micro-channels, micro-valves, micro-reaction pools (chambers) and other functional units, which can complete the precise control of liquid and gas flow in the chip, thereby To realize a specific biochemical reaction function.

3.2 skin-on-a-chip

Microfluidic chips in vitro can generate micro cells and tissues that can mimic the biochemical and physiological characteristics of the skin and have barrier structure and function. Tissue culture devices.

3.3 [Source. GB/T 2410-2008, 3.2]

The ratio of the luminous flux passing through the sample to the luminous flux incident on the sample, expressed as a percentage.

3.4 Leaktightness

The property of the chip and its associated materials to prevent the contents from spilling or other substances from entering.
