2 Customer Questions
What is the proper way to clean these test tubes after each use?
Answer by • Jun 24, 2018
The tubes can be cleaned with hot water and air dried.
What size (dimensions) and capacity are these test tubes?
Answer by • Aug 10, 2021
The test tubes are meant to hold the water testing sample of about 5 milliliters (some rounding occurs here) marked with an indicator line and will hold 2-3 more milliliters if they are filled to the very top. The test tube is 12-13 millimeters in diameter and 85 millimeters in height. Using test tubes of different specifications with API reagents is not advised, for accuracy purposes.
