Description
Gay-Lussac pycnometer, calibrated to DIN ISO 3507, is a precision density flask manufactured from borosilicate glass 3.3 with a nominal capacity of 10 cm³. It is fitted with a PTFE stopper and supplied with an individual certificate, supporting traceable volumetric work in analytical and quality-control laboratories. The classic Gay-Lussac geometry, combined with white inscription, facilitates clear filling to the capillary mark and straightforward weighing for specific-gravity and density determinations. Borosilicate glass 3.3 provides chemical durability and low thermal expansion for stable volume under normal laboratory temperature control. The PTFE stopper offers chemical resistance and a reliable seal during equilibration and transport to the balance. From manufacturer Hecht, this single-piece instrument is intended for routine pycnometric procedures where documented calibration and a compact 10 cm³ working volume are required. It is suited to liquids compatible with Boro 3.3 glass and PTFE and is used in accordance with DIN ISO 3507 practice for accurate mass-to-volume measurements.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Specific gravity bottles, Gay Lussac, calibrated, with PTFE-stopper and
What is this article?
Specific gravity bottles, Gay Lussac, calibrated, with PTFE-stopper and is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
