    • PURPOSE:To prevent air bubbles from penetrating a capillary tube by placing an air tube in a position on the vertical line of a sampling hole branching the capillary tube from the air tube with a lower sample storing bulb as the branch point. CONSTITUTION:An air tube 1 is placed in a position on the vertical line of a sampling hole 4, and a capillary tube 2 is branched from the air tube 1 in the part of a lower sample storing bulb 3. The sampling hole 4 of this vertically fixed viscometer is immersed in a sample in a vessel so that the sample is sucked easily from below. Next, the air tube 1 is closed, and the sample is sucked to the middle of an upper sample storing bulb 5 through the capillary tube 2 by pressure reduction. Then, the vessel where the sample is stored is removed from the sampling hole 4, and the viscometer is left still for a prescribed time. Air may penetrate the viscometer from the sampling hole 4 while it is left still, and air bubbles of penetrated air are floated vertically and are joined to air in the air tube 1 and do not penetrate the branched capillary tube 2. Thus, an accurate kinematic viscosity is measured.
    • 目的:通过将空气管放置在采样孔垂直线上的一个位置,防止气泡穿透毛细管,该采样孔将毛细管与空气管分开,并以较低的样品存放灯泡作为分支点。 构成:将空气管1配置在取样孔4的垂直线上的位置,毛细管2从下部样品存储灯泡3的一部分中的空气管1分支。这样的取样孔4 将垂直固定的粘度计浸入容器中的样品中,使样品从下方容易地吸入。 接下来,关闭空气管1,通过减压将样品通过毛细管2吸入上部样品保存用灯泡5的中间。 然后,从取样孔4取出试样收纳的容器,将粘度计静置一定时间。 空气可能在静止时从采样孔4渗透粘度计,并且穿透空气的气泡垂直浮动并与空气管1中的空气接合,并且不会穿透分支的毛细管2.因此,精确的运动学 测量粘度。
