Patent number: 8021495Abstract: Provided are a simple and inexpensive cleaning apparatus and a method for cleaning capable of effectively cleaning the outer wall surface of a pipette. A pipette to be cleaned is positioned in a concave portion of the cleaning apparatus, and a cleaning liquid passed through inside of the pipette strikes an inner circumferential surface of the concave portion and bounces therefrom to splash against the outer wall surface of the pipette, thereby cleaning the outer surface. With above arrangement, without using an ejection apparatus of cleaning water, effect equivalent to that with the ejection apparatus can be attained. Furthermore, both the inner wall surface and the outer wall surface of the pipette can be cleaned by a single operation using the same cleaning water, thereby attaining easy internal cleaning work and short cleaning time.Type: GrantFiled: April 21, 2006Date of Patent: September 20, 2011Assignee: Wako Pure Chemical Industries, Ltd.Inventors: Masayoshi Hayashi, Kazuhito Tanimoto, Keiko Sasaki
