PROBLEM TO BE SOLVED: To provide a tip capable of effectively fractionating and purifying target biopolymers and impurities from trace amounts of sample and specimen mainly in fields of biochemistry, agricultural chemistry, molecular biology, medicine, clinical medicine, clinical medicinal tests, etc. SOLUTION: A tip 6 can be attached to a tip attaching opening 3 at the tip of a repetitive type dispenser 1 for fractionating and dispensing a small amount of liquid, and a liquid sample can be injected into the tip 6 and be discharged afterwards. Plug bodies capable of passing gases and liquids are fixed at a location inside the tip 6 close to the center part from the upper part and close to the center part from the lower part or in the vicinity of an injecting and discharging opening part 7, and a silica carrier, a synthetic polymer carrier, a cellulose carrier, etc., which are solid-phase carrier for a liquid chromatograph, are introduced to and held in a space part sandwiched by the upper and lower plug bodies. |
