Clay liner tiles are relatively inexpensive-about $10 for a typical 24â²-tall unit. But what you save on materials will most likely exceed the cost of installation labor.

Beaker tongs are best used to hold a hot beaker. Pick up hot glassware without heat protection and your skin will be injured. This is as true in the laboratory as it is in your kitchen. Lab tongs, part of a range of laboratory safety equipment, help you move hot ceramics and glassware safely.
LAB SAFETY!! Holding and heating liquids. Can also hold solids. If the temperature of the beaker is higher than boiling water, do not use beaker tongs. See (1), Used for picking up hot beakers containing ONLY boiling water. DO NOT pick up anything hotter than a beaker with boiling water. The rubber on the beaker tongs can burn at higher temperatures.
