Study Notes

Laboratory Glassware and Equipment

Aspirator: A device that produces a vacuum using the venturi effect. Fluid (liquid or gaseous) flows through a narrowing tube.
Beaker: Used as a reaction container or to hold liquid or solid samples.
Erlenmeyer Flask: Useful for containing reactions or holding liquid samples.
Burette Clamp: A laboratory tool to securely hold a burette during precise volume measurement procedures.
Test Tube Brush: Used for cleaning test tubes.
Test Tube Rack: Holds test tubes upright when containing chemicals and upside down to dry. Made of wood, metal, or plastic.
Porcelain Spatula: Used to take small amounts of powdered compounds in a laboratory setting.
Medicine Dropper: Used for adding liquids drop by drop.
Stirring Rod: Used for mixing liquids or solids and liquids.
Funnel: Used for funneling liquids from one container to another or for filtering when equipped with filter paper.
Wire Gauze: Placed on a ring, supports beakers to be heated with Bunsen burners.
Metal Spatula: Used for scraping and transferring small amounts of powders or solids.
Test Tube Holder: Used for holding test tubes when they cannot be touched directly.
Clay Triangle: Placed on a ring attached to a ring stand, supports a funnel, crucible, or evaporating dish.
Pipette: Used for dispensing small quantities of liquids.
Evaporating Dish: Used to separate liquids and solids from a solution by allowing water to evaporate.
Laboratory Tripod: A three-legged platform that supports flasks and beakers.
Laboratory Thermometer: Measures boiling points during experiments and the temperature of substances.
Mortar and Pestle: Used to grind and mix substances.
Watch Glass: Used for holding small samples or covering beakers or evaporating dishes.
Test Tube: Used to hold, mix, and heat for chemical experiments.
Crucible Tongs: Used for grasping and taking a hot crucible.
Alcohol Lamp: Used for heating, sterilization, and combustion in a laboratory.
Crucible and Cover: Used to heat solid chemicals at high temperatures.
Bunsen Burner: A type of gas burner used in many chemistry procedures for heating, combusting substances, and sterilizing objects.
Triple Beam Balance: Used to measure the mass of small objects.

Laboratory Policies

Classroom Discipline: Maintaining discipline is essential in the laboratory. Eating, smoking, and playing are prohibited. Handling toxic chemicals warrants special attention.
Class Attendance: Students are expected to attend the entire duration of the class for the complete learning experience. Absence is marked when a student leaves the classroom before the conclusion of the class.
Personal Protective Equipment (PPE): Laboratory gowns or aprons and surgical gloves must be worn during experiments to adequately protect the user from possible harmful effects.
Laboratory Materials: Students with the correct materials needed for the experiment are permitted. Students sent out of the laboratory due to lacking the necessary materials will be marked absent.
Manuals: Authorized printed copies of the laboratory manual are mandatory and will be given credit for the experimental result. No photocopies are graded and given credit. Numerical computations should use scratch paper, and the final answer should be written using the space designated on the manual. Answers need to be presented with the correct number of significant figures. Measurement units must be indicated.
