Description
Pressure gauge with 2 scale ranges is a precision dial manometer intended for laboratory vacuum monitoring. It presents pressure on dual complementary scales covering 1000-0 mbar and 760-0 mmHg, allowing convenient reading in both common units. The complete assembly includes an adapter from GL 32 thread to core NS 29/32 ground joint together with a ventilation valve, enabling direct connection to standard glassware. Constructed from borosilicate glass 3.3, the instrument is suitable for work in the coarse vacuum range and supports processes such as distillation, evaporation or filtration under reduced pressure. This manometer from manufacturer Rettberg combines clear dual-scale indication with practical joint compatibility. With a net weight of 0,255 kg it remains easy to handle and mount on existing apparatus. The robust glass design prioritises durability and readability for consistent vacuum control in everyday laboratory operations.

Questions about Vacuum gauge with 2 scale ranges, with adapter thread GL 32 to
What is this article?
Vacuum gauge with 2 scale ranges, with adapter thread GL 32 to is the article on this page. Luminix Health distributes Rettberg 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.
