Title
(EN) PIPETTE ADAPTOR, PIPETTE FOR ABSORBANCE MEASUREMENT, TIP, AND METHOD AND APPARATUS FOR ABSORBANCE MEASUREMENT
(FR) ADAPTATEUR DE PIPETTE, PIPETTE DE MESURE PAR ABSORBANCE, POINTE, ET PROCEDE ET APPAREIL DE MESURE PAR ABSORBANCE
Abstract
(EN)
A pipette (1) for absorbance measurement comprises a pipette (10) and a pipette adaptor (20) that includes a pipette holder (21) for receiving the end of the pipette (10) and a tip holder (22) for holding a tip (30). When interposed between the pipette (10) and the tip (30), the pipette adaptor (20) provides a space (20A) communicating with a hollow in the pipette (10) and a hollow in the tip (30). The pipette adaptor (20) further comprises a window (23) for introducing external test light into the internal space (20A), and a reflector (24) that reflects the test light introduced to the space (20A) through the window (23) so that the reflected light may travel through the hollow in the tip holder (22) toward a suction hole (31) for attracting a sample at the end of the tip (30).
(FR)
L'invention concerne une pipette (1) de mesure par absorbance, qui comprend une pipette (10), et un adaptateur de pipette (20) muni d'un support de pipette (21) pour recevoir l'extrémité de la pipette (10) et d'un support de pointe (22) pour recevoir une pointe (30). L'adaptateur de pipette (20), lorsqu'il est intercalé entre la pipette (10) et la pointe (30), présente un espace (20A) communiquant avec un creux ménagé dans la pipette (10) et un creux ménagé dans la pointe (30). L'adaptateur de pipette (20) comprend en outre une fenêtre (23) à travers laquelle un voyant d'essai extérieur est introduit dans l'espace intérieur (20A), et un réflecteur (24) qui réfléchit la lumière émise par le voyant d'essai introduit dans l'espace (20A) à travers la fenêtre (23), de sorte que la lumière réfléchie parcourt le creux ménagé dans le support de pointe (22) en direction d'un trou d'aspiration (31) en vue d'attirer un échantillon à l'extrémité de la pointe (30).
