The surface tension of liquids can be measured with small glass tube one-third of a millimeter in diameter. I have used this device to measure urine
ST. This year the provider did not return to New York to sell.
Are there any glassware of this diameter and about 6 inches? Someone knows some other practical and inexpensive method for measuring the ST?

The quartz tubing we use with our microfluidic devices have a few hundred µm ID.
And I think thin film chromatography micro-pipettes have a similar ID, and those are super-cheap.
