Product Description
Measuring surface tension does not have to require an expensive tensiometer. This capillary rise apparatus lets students and analysts determine surface tension simply by reading how high a liquid climbs in a fine glass tube. It is a simple, hands-on way to demonstrate and measure capillary action in teaching and research settings.
This listing is for Kimble catalog number 914818: Surface Tension Apparatus, Range 0-100. The set includes a borosilicate glass 3.3 capillary tube with a nominal 0.5 mm bore, graduated from 0 to 10 cm in 0.1 cm steps, a glass outer cylinder with a side tubulation and a rubber stopper that centers the capillary. A pipette bulb attached to the outer tube expels air to set the liquid level. It is sold individually. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
Key Features
- Capillary rise method – Determines surface tension from liquid height in the tube.
- Graduated capillary – 0 to 10 cm scale in 0.1 cm increments.
- Centered tube – Rubber stopper holds the capillary in the middle of the cylinder.
- Borosilicate glass – Clear, durable glass for easy reading.
