Patent number: 7776572Abstract: Hydrophobic polymer surfaces whose level of protein binding is less than about 50-80 ng/cm2 are achieved by: (1) applying a coating solution composed of a solvent and a non-ionic surfactant having a HLB number of less than 5 to the surface; and (2) drying the surface to remove the solvent and thereby bring the surfactant into direct contact with the hydrophobic polymer. The combination of a low HLB number and the drying step have been found to produce low binding surfaces which can withstand multiple washes with water and/or protein-containing solutions Alternatively, the low binding surfaces can be produced by applying the non-ionic surfactant to the mold surfaces which contact molten polymer and form the polymer into a desired shape, e.g., into a multi-well plate, a pipette tip, or the like. Further, the low binding surfaces may be produced by incorporating non-soluble, non-ionic surfactants having an HLB number of less than or equal to 10 into a polymer blend prior to molding the article.Type: GrantFiled: February 16, 2007Date of Patent: August 17, 2010Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Edward John Fewkes, Jr., James Arthur Griffin, Frances M.

Publication number: 20100047898Abstract: A pipette includes a tubular body having an internal passage, a first end and a second end. The tubular body is deformed inward to create a narrow constriction or slit within the internal passage of the pipette. When vacuum is applied to the pipette and a solution is drawn into the pipette, the slit increases the velocity of the solution while gently deforming and separating clumps of matter (e.g., colonies of bacteria) contained in the solution. As the deformed bacterial colony passes through the slit, the bacteria solution is mixed due to turbulent flow within the pipette created by the increase in velocity. Bacteria colony size is further reduced by alternating the pipette flow direction to cycle the bacteria through the slit two or more times. A sloped entrance to the slit also prevents the oily bacteria from clogging the slit during cycle reversals.Type: ApplicationFiled: August 19, 2008Publication date: February 25, 2010Inventor: James C.
