《GB/T 21785-2008实验室玻璃器皿密度计》由TC251（全国危险化学品管理标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准为首次发布。本标准规定了一系列密度计在实验室用于常规测量液体密度时所应具备的条件。本标准等同采用ＩＳＯ３５０７：１９９９《实验室玻璃器皿　密度计》（英文版）。

Scope

This standard specifies the conditions that a series of densitometers should meet when they are used in the laboratory to routinely measure the density of liquids. Dedicated densitometers for special products or other densitometers not normally used are not covered by this standard. Sufficient information to define these densitometers should be contained in relevant International Standards specifying or describing their use. Appendix A contains a set of devices suitable for adjusting the liquid level in the neck of a Reischauer densitometer.
