    • PURPOSE: To culture adherent cells in high efficiency, by proliferating the cells on the substrate without immersing the substrate in culture liquid while contacting the substrate with the culture liquid.
      CONSTITUTION: The substrate container 3 is fully packed with the substrates 1, the culture liquid is sprayed from the sprayer 4 placed at the top of the culture tank 2 to effect the thorough contact of the liquid with the substrates 1, and the culture liquid dripped to the bottom of the container 3 is collected in the tank 20 and circulated to the sprayer 4 with a pump. The substrate container 3 is aerated with a gas having necessary composition simultaneously to the initiation of the culture. The gas is introduced into the culture tank 2 from the gas diffuser 17 attached at the top or bottom of the culture tank and made to contact countercurrently or concurrently with the culture liquid. The adherent cells can be proliferated on the substrate which is not immersed in but contacted with the culture liquid, in high efficiency.

    • 目的:以高效率培养贴壁细胞,通过增加底物上的细胞,而不将基质浸入培养液中,同时使基质与培养液接触。 构成:将基材容器3充满基材1,从放置在培养槽2顶部的喷雾器4喷出培养液,使液体与基材1充分接触,滴加培养液 将容器3的底部收集在罐20中并用泵循环到喷雾器4中。 基底容器3在培养开始时同时具有必要组成的气体充气。 将气体从附着在培养罐顶部或底部的气体扩散器17引入培养槽2中,并与培养液逆流或同时接触。 粘附细胞可以在没有浸入培养液中但与培养液接触的基质上增殖,而且效率高。
