Termisk Expansion

U shaped clamping set-up with a metal rib and fastening screw for demonstrating the linear expansion of metals on heating, as well as the tremendous forces which can be exerted in the process. The set includes 10 cast-iron bolts for breaking in the course of the experiment. Diameter for bolt hole: approx. 11 mm Length […]

Stable glass flask on a stand for demonstrating the flow of heat in a non-uniformly heated liquid. With filling hole for filling with water and a small quantity of potassium permanganate crystals for colouring. Glass flask: 300×150 mm² Tube diameter: 14 mm Height: 250 mm

An arrangement for demonstrating the expansion of solids on heating. After heating in a burner flame, the ball no longer fits through the bore in the bracket. Steel ball with chain and handle. Dimensions of the bracket in mm: approx. 40x50x40 mm² Diameter of ball: approx. 22 mm Length of handle with shaft: approx. 225 […]

A device for measuring the thermal expansion of solids in dependence on length and material. The scope of delivery includes three sample tubes (steel, brass and glass) which are heated by passing water vapor through them. Consists of a base strip with a fixed bearing, pilot bearing, pointer and projectable scale. Scale dimensions: approx. 140×200 […]

Analogue gauge for measuring minimal changes in length plus an adapter for fitting a gauge dial as an enhancement to the extension apparatus D (U15400). Measurement Range: 0 – 10 mm Resolution: 0.01 mm

En apparat för mätning av den termiska expansionen i fasta ämnen beroende på längd och material. Leveransens omfattning inkluderar tre provrör (stål, mässing och glas) som värms upp genom att låta vattenånga passera genom dem. Består av en baslist med en fixerad bäring, pilotbäring, pekare och projicerbar skala. Skalans mått: ca 140 x 200 mm² […]
