Common Laboratory Apparatus

is used in laboratories as a heat source for standard chemistry and microbiology experiments, for flame sterilization of equipment by heating, and for combustion processes that require a controlled, low-heat, open flame. It uses alcohol as fuel, drawn up a wick by capillary action, and is an alternative to more powerful heating devices like Bunsen burners or hot plates.

(a)  

create a vacuum to suction liquids, air, or particles for various tasks like filtration, liquid handling, vacuum drying, and collect- ing samples. I

(a)  

provide a controlled, adjustable open flame for heating, sterilizing, and combusting substances in a laboratory setting.

(a)  

to hold, mix, stir, and heat liquids, and to collect filtrates from filtering operations.

(a)  

precisely measuring and dispensing variable volumes of liquids, most commonly for titration, a chemical analysis technique where a solution of known concentration (titrant) is slowly added to a solution of unknown concentration until the reaction is complete.

(a)  

a piece of apparatus designed to hold and sup- port two burettes simultaneously on a laboratory stand.

(a)  

to physicaly hold and contain substances during high

temperature ex-periments.

(a)  

heating, melting, ashing (burning to ash), evaporation, and carrying out high-temperature chemical reactions.

(a)  

serves as the primary vessel to hold a liquid mixture for heating, separation via distillation, and collection of purified components.

(a)  

to safely and accurately transfer liquids or powders into containers with narrow openings, preventing spillage and contamination.
