Description

Tubes specifically designed for checking the surface tension of liquids. Each tube is accurately calibrated to help quickly determine surface tension by the drop count method. Each tube is graduated above and below the bulb. Tubes are available in 2.5mL, 3.5mL and 5.0mL sizes. The 2.5 and 5.0mL sizes allow flexibility in sample size of most liquid baths, while the 3.5mL size is used for more viscous applications. Available individually or in a complete set of 3 tubes (1 of each size) in a protective case. All tubes supplied with instructions for use.
