Chem 1411 Lab - Equipment

Graduated cylinder

used to accurately measure the volume of liquids with precise calibration marks, often before transferring them into a beaker or Erlenmeyer flask

Bunsen burner

provides an open flame heat source for heating substances in equipment like crucibles, test tubes, or evaporating dishes that are often held above the flame by a ring stand and iron ring or supported by a wire gauze

Erlenmeyer flask

a conical piece of laboratory glassware used to hold and mix chemicals and may have approximate volume graduations. can be clamped to a ring stand with a utility clamp and used with a stopper, funnel, or buret for controlled reactions or filtration.

Forceps

are used to grasp and transfer small solid objects, such as a piece of metal or a filter
paper, into or out of equipment like beakers or crucibles.

Utility clamp

attaches to a ring stand to securely hold items such as test tubes, burets,
or flasks during experiments

Beaker

is a cylindrical piece of laboratory glassware used to hold, mix, and heat liquids and solids, and typically has approximate volume graduations. can be placed on wire gauze over a Bunsen burner or used to receive filtrate from a Büchner funnel or stemmed funnel.

Büchner funnel

is used with filter paper and a vacuum pump connected to a side-arm Erlenmeyer flask to perform vacuum filtration.

Clay triangle

supports a crucible over a Bunsen burner, often resting on an iron ring attached to a ring stand

Spatula

transfers small quantities of solid chemicals to beakers, evaporating dishes, or
crucibles

Crucible

used to heat small quantities of solid substances to high temperatures,
typically used with a cover and supported by a clay triangle on a ring stand

Stemmed funnel

helps pour liquids into containers like graduated cylinders or
Erlenmeyer flasks, and can also hold filter paper for gravity filtration

Ring stand

serves as a support structure for holding clamps, iron rings, or clay triangles that secure items like flasks, crucibles, or funnels during experiments

Iron ring

attaches to a ring stand to support equipment such as wire gauze for beakers or a clay triangle for crucibles.

Test tube

is a glass cylinder with a rounded bottom that holds small amounts of substances for reactions or heating, often placed in a test tube holder or utility clamp over a flame

Evaporating dish

is a ceramic dish used to heat solutions to evaporate the solvent or dry collected solids, often placed in a drying oven or on wire gauze over a Bunsen burner.

Watch glass

holds small samples, covers beakers to prevent splashing, or allows evaporation of a small amount of liquid

Wire gauze

is placed on an iron ring to evenly distribute heat beneath glassware like beakers or flasks during heating.

Buret

precisely dispenses variable amounts of liquid and has highly precise volume
graduations, typically clamped vertically on a ring stand during titrations into a flask

Thermometer

measures the temperature of substances in containers like beakers or test tubes, often held in place by a utility clamp on a ring stand.
