气体容量法定碳,使用有白色带和蓝线的量气管读取刻度和看弯月面很不清晰,给准确快速读数带来一定困难.为此我们用下面的办法使量气管的刻度和弯月面变得非常清晰,以便于准确快速读数。用28×4公分左右的镜子(可向玻璃商店购买镜子的边角来做,此尺寸仅供参考)。两头用化验室常用的橡皮瓶塞(尺寸与镜子宽度相应中间开槽)夹紧,然后在量气管后面把它竖直夹在固定量气管的两块木板之间即可。这时可根据室内光线转动镜子到一定角度,使量气管刻度、弯月面达到最清晰为止。
Gas capacity of statutory carbon, the use of white with a blue line and the amount of gas tracheal reading scale and look at the meniscus is not clear, to bring accurate and rapid readings bring some difficulties .To this we use the following method to make the amount of tracheal calibration and bending Moon surface becomes very clear, so accurate and fast readings. Use 28 × 4 centimeters or so mirrors (available at glass shops to buy the corners of the mirror to do, this size is for reference only). Two commonly used laboratory rubber bottle stopper (corresponding to the size of the width of the mirror slotted) and then clamp it in the vertical pipe after the amount of tracheal sandwiched between the fixed amount of trachea can be between two pieces of wood. At this time, the mirror can be rotated to a certain angle according to the light in the room, so that the gas tracheal scale and the meniscus reach the clearest point.
