Cost-Effective Teacher
A Novel W-Tube for Microscale Experiments in Chemistry

Abstract
There are some experiments in chemistry where there is a need to test for the presence or absence of a certain gas. The experimental setup for these tests requires appreciable quantities of chemicals, time, and specialized apparatus. A simple W-tube is described to perform these tests quickly and economically at the microscale level.
