Device for sponge substrate washing or chemical reaction

The invention provides a device for sponge substrate washing or chemical reaction. The device consists of an outer tube and an inner tube put in the outer tube, wherein the bottom of the inner tube isconnected and fixed to the bottom of the outer tube; a gap which is not smaller than 1cm is formed between the inner tube and the outer tube; holes are formed in the inner tube wall; a press plate which is connected with a power device through a fixing rod can do reciprocating movement in the inner tube and can be moved out from the inner tube. Holes are also formed in the press plate; the outertube is connected with a valve; liquid in the tube can be discharged out. The whole device can form a sealed system through a cover. 一种用于海绵物质洗涤或化学反应的装置，装置由外筒和置于其中的内筒组成，内筒的底部与外筒底部连接固定。内筒外筒间有不小于1厘米的空隙，内筒壁开有孔洞。一个与通过固定杆与动力装置连接的压板可在内筒内往复运动，并可从内筒内移出。压板上也开有孔洞。外筒连有阀门，可将筒内液体排出。整个装置可以通过一个盖子形成封闭体系。
