Why an Unmarked Jar Suits Hydrometer Readings
Hydrometer jars are deliberately left without printed graduation markings because their job is to hold a stable, sufficiently deep column of liquid so a separate hydrometer can float freely and settle to its equilibrium depth — the reading is taken from the hydrometer stem, not from the jar. A round base and the absence of a pouring spout keep the internal diameter consistent from top to bottom, avoiding the taper distortion a spout can introduce near the rim, which matters when a hydrometer needs adequate clearance from the jar walls to float without touching them. Borosilicate glass construction resists the mild chemical exposure common in specific-gravity testing of oils, syrups, acids and other industrial liquids.
Frequently Asked Questions
What is the Hydrometer Jar Round Base used for?

Does the jar have graduation markings?
No, this jar is supplied without calibration markup — readings are taken from the hydrometer, not the jar.
Does the jar have a pouring spout?
No, this version is supplied without a spout for a consistent internal diameter.
