Description
Pycnometer, 500 ml, NS 45/40 is a laboratory glass vessel for density and specific-gravity determinations on liquid samples. The 500 ml nominal capacity supports larger aliquots when higher sample volume improves weighing precision or when bulk liquids must be characterised under controlled filling conditions. An NS 45/40 ground joint provides a standardised closure interface for the stopper, helping to define the calibrated volume and limit evaporation during equilibration and weighing. This pycnometer belongs to the family of volumetric flasks and vessels used in volumetric analysis and is suited to quality-control, formulation, and teaching laboratories that determine density by classical gravimetric methods. Offered as a single unit from manufacturer Winzer, the instrument is ready for integration into routine density workflows alongside analytical balances and temperature control. With a weight of 0,586 kg, the 500 ml body remains stable on the balance pan while still being manageable during filling, thermostatting, and cleaning. The clear joint specification NS 45/40 assists users in matching stoppers and accessories within existing ground-glass inventories.

Questions about Pycnometer, 500 ml, NS 45/40, 1 unit(s)
What is this article?
Pycnometer, 500 ml, NS 45/40, 1 unit(s) is the article on this page. Luminix Health distributes Winzer for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
Which category should I open next?
