beakers

useful as a reaction container or to hold liquid or

solid samples. They are also used to catch liquids from titrations

and filtrates from filtering operations.

bunsen burners

sources of heat

burets

for addition of a precise volume of liquid. The volume

of liquid added can be determined to the nearest 0.01 mL with

practice.

clay triangles

are placed on a ring attached to a ring stand as a

support for a funnel, crucible, or evaporating dish.

erlenmeyer flasks

useful to contain reactions or to

hold liquid samples. They are also useful to catch filtrates.

glass funnels

for funneling liquids from one container

to another or for filtering when equipped with filter paper.

graduated cylinders

for measurement of an amount of

liquid. The volume of liquid can be estimated to the nearest

0.1 mL with practice.

hot plates

sources of heat when open flame isn’t available

pipets

for small quantities of liquids

ring stand with rings

for holding pieces of glassware in place

volumetric flasks

used to measure precise volumes or to make precise dilutions

wash bottles

used for dispensing small quantities of distilled water

watch glasses

small, concave glass dishes used to hold solids or cover beakers.

wire gauze

on a ring supports beakers to be heated by bunsen burners
