Patent number: 5979475Abstract: A highly clean fluid treatment system having a small system volume is provided by using a Bernoulli holder to accomplish stable holding of a specimen in a simple configuration. A holder having a specimen hold face formed almost the same as a specimen or having a Bernoulli effect producing region and a region surrounding the Bernoulli region made of a specific combination of materials is used and fluid supply sources are connected to the holder for supplying one or more fluids containing a treatment agent of a specimen. Since a force for inhibiting a position shift occurs on the end face of the specimen 10, stable specimen holding is enabled. The space between the specimen and the holder where treatment is executed is narrow and fluid always flows from the treatment space to the outside. Therefore, the fluid treatment system of a small volume producing high treatment efficiency and minimizing the chances of recontamination of the specimen can be provided.Type: GrantFiled: April 28, 1995Date of Patent: November 9, 1999Assignee: Hitachi, Ltd.Inventors: Takao Satoh, Haruo Itoh, Hitoshi Oka, Yoichi Takahara, Akio Saito
