China Manufacture Glass-Rod-Draw Machine Glass Fiber Rod/ Solid Fiberglass Tube

In experiments, glass rods can be used to transfer solid substances, such as removing solid reagents from reagent bottles and transferring them to other containers. The use of glass rods for transfer can prevent the loss or contamination of solid substances. Although not commonly used, in some experiments, glass rods can also be used to dip gas samples. For example, when detecting gas composition, a glass rod can be used to dip the gas and transfer it to the detection device.

When transferring or filtering solutions, glass rods can serve as drainage devices. For example, in a filtration experiment, using a glass rod to drain the liquid to be filtered into a funnel can prevent liquid splashing and accelerate the filtration speed. A glass rod can be dipped into a solution to detect its acidity or alkalinity, or a small amount of solution can be used for other experiments. When dipping into the solution, it is necessary to keep the glass rod clean to avoid contaminating the solution.
