小型水银气压计是验证气态方程的一种较理想的仪器。对于它的清洗及灌注,我们采用下列器材和方法,可以达到简易、可靠的目的。同时,对玻一马定律演示器、曲管式气压计的清洗及灌注均可采用此法。一、器材10ml 或20ml 针筒一支16号或8号注射器针头一枚。比气压计 U 型管稍长,而直径比管径略小的塑料导管一根,具体可用单股或多股塑料导线抽去铜芯制成;清洗液、蒸溜水、水银。二、清洗及灌注方法1.如图,先把导管塞到 U 型管的底部,在接上抽满清洗液的针简后,将清洗液注入,并使其不
Small mercury barometer is a better instrument to verify the gas equation. For its cleaning and perfusion, we use the following equipment and methods for simple and reliable purposes. At the same time, the Bollinger law demonstrator, curved tube barometer cleaning and perfusion can be used this method. First, the equipment 10ml or 20ml syringe a 16 or 8 syringe needle one. Than the pressure gauge U-tube slightly longer, while the diameter is slightly smaller than the diameter of a plastic catheter, the concrete can be single or multi-strand plastic wire drawn copper core; cleaning fluid, distilled water, mercury. Second, the cleaning and perfusion method 1. As shown in the figure, the first catheter to the bottom of the U-tube, connected to the needle pumping fluid pumping full, the cleaning fluid injection, and to not
