Round bottom flasks, also called round bottomed flasks or RB flasks, are types of flasks having spherical bottoms used as laboratory glassware mostly for chemical or biochemical work
Round bottom flasks
A condenser is an apparatus or item of equipment used to condense (change the physical state of a substance from its gaseous to its liquid state)
Glass Condenser
Filter paper is a semi-permeable paper barrier placed perpendicular to a liquid or air flow. It is used to separate fine substances from liquids or air
Filter paper
A separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate partition the components of a mixture into two immiscible solvent phases of different densities
Separatory funnel
A filtering flask is a piece of labware used to separate solids from fluids in filtration operations
Filtering flask
A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker
Watch glass
Used with a filtering funnel such as a Buchner funnel to filter particles
