Inorganic Chem: lab equipments

Microscope

• Used to look at finer details of small project

• Magnifies the object up to thousands times

Weighing Balances

• Used to determine the mass of substances

Erlenmeyer Flask

• Conical-shapes containers with narrow necks

• Used for  mixing, heating and storing liquids - when you need to prevent splashes

• Can be fitted with stoppers, caps, corks

• For filtration, reaction vessels or containers for culture

Test Tubes

• Holds reagents, conducts small-scale reactions, culture microorganisms

• Use to hold, for heating, or mixing liquids or solids

Graduated cylinder

• Used to accurate measure the volume of liquids

• They have precise graduation marks

• It has a spout for easy pouring

Pipette

• Used for precise measurement and then transferring small volumes of liquid

• Have calibrated scale for volume selection

• Used to make dilutions, transfer of liquid from another container to sample container, and preparing standards.

Buret

• Used for precise tiltrations in analytical chemistry

• Ther control the dispensing of a titrant into a solution

• Long graduated —---- stopcock at the bottom

Crucible

• They are heat-resistant that can withstand high temperatures

• Made of porcelain or ceramic

• Small cylindrical in shape and has lids

Florence Flask

• Used for boiling and heating liquids

• Round bottom

• Long neck with a rubber stopper or glass tubing

• Used for distillation

Evaporating Dish

• Shallow, flat-bottomed containers used for evaporating solvents from solutions

• Porcelain or borosilicate glass - resistant to high temp

• Gently heating them to drive of solvents

Hot plate

• Electric heating device used to heat glassware or other containers with a flat surface

• Boiling water, heating solutions, or conducting reactions that required a controlled and cons—--

Centrifuge

• Used for separating components of a liquid or mixture based on density by spinning them at high speed.

• They have a rotor that holds the test tubes and can generate centrifuge force

Stirring rod

• Long thin glass or plastic rod used for manually stirring liquids or suspensions

Funnel

• Used for transferring liquids on fine-grained substances from one container to another to avoid spillage

• Have a wide tapered opening at the top and narrow spout at the bottom

Magnetic Stirrer

• Use a rotating magnetic field to create a vortex in a liquid which stirs the contents without manual labor

• For continuous mixing of solutions

• Usually the hot plate had a magnet for this
