consists of a gas inlet, burner tube, air control vent and gas control
provides a safe and convenient way to perform reactions that require heating
using a Bunsen burner
connects to a ring stand and provides a stable, elevated platrom for the
reaction vessels
sits on the iron ring to provide a place to stand a beaker or an Erlenm eyer flask
and spread the heat uniformly on the bottom of the glassware
used for holding and organizing test tubes on the lab counter (be careful as the
plastic ones may melt if they come in contact with very hot test tubes)
used for reacting and heating small amounts of chemicals
used to accurately measure volumes of liquids
