Abstract
(EN)
A dispenser unit comprising syringe (12) for accommodating of a liquid thereinside and plunger (12b) capable of forward and backward movement in the interior of the syringe (12) to thereby discharge the liquid, through discharge aperture (12d) of the syringe (12), outside the syringe (12), wherein at least either the internal wall of the syringe (12) or the surface of the plunger (12b) is provided with a hydrophilic film to thereby enable easy removal of bubbles sticking to the interior of the syringe or the surface of the plunger.
(FR)
L'invention concerne une unité de distributeur comportant une seringue (12) pouvant recevoir un liquide et un piston (12b) capable d'un mouvement avant-arrière à l'intérieur de la seringue (12), déchargeant ainsi le liquide par l'ouverture de décharge (12d) de la seringue (12) vers l'extérieur de la seringue (12), au moins la paroi interne de la seringue (12) ou la surface du piston (12b) étant dotée d'un film hydrophile permettant un retrait facile des bulles fixées à l'intérieur de la seringue ou à la surface du piston.
(JA)
 この発明にかかる分注装置は、液体を内部に収容するシリンジ12と、シリンジ12内部において進退動作を行って該シリンジ12に形成された吐出口12dから液体を該シリンジ12外部に吐出させるプランジャ12bとを備えた分注装置であって、シリンジ12の内壁またはプランジャ12b表面の少なくともいずれか一方に親水膜が形成されており、シリンジの内部またはプランジャの表面に付着する気泡を容易に除去することができる。
