Science Lab Equipment For exact volume measurements of liquids. Pipet on the left is a Volumetric pipet. It has only one graduation for delivering one exact volume. Pipet on the right is a Mohr pipet. It has graduations for delivering any number of exact volumes. Pipet There are several styles of fillers used to draw liquids into a pipet. A standard pipet bulb is the most commonly used one. Never draw a liquid into a pipet with your mouth. Pipet filler Used in conjunction with a vacuum connection to a water faucet to speed up filtration. Filter flask Heat or store liquids. Heats faster. Erlenmeyer flask The rounded bottom of the florence flask makes it ideal for boiling liquids EVENLY. It also makes this flask easy to tip over when sitting on the lab table. Florence flask The volumetric flask is used to make solutions. It has a precise graduation line in the neck of the flask. A solute is placed into the flask, then the solvent is used to bring the total volume up to the graduation. Volumetric flask^
Hold or heat liquids. The volume graduations on beakers should be used only for "ballpark" estimates. Beaker* Used to make accurate Used measurements to make accurate of liquid measurements volumes. The bumper of liquid volumes. ring is to The prevent bumper ring on larger cylindars is to breakage if tipped over. prevent breakage if tipped over. Keep Keep it near it the near top the top. Graduated cylinder* This dish is used to recover dissolved solids by evaporation. While it can be heated, it should not be used for "strong" heating. Evaporating dish* A watch glass to cover beakers or hold solids being weighed or transported. Watch glass* When attached to the ring stand, this iron ring is used to support glassware above the lab table. Support ring* When attached to the ring stand, this clamp is used to hold a large test tube or Florence flask above the lab table. Utility clamp Crucibles are used as a container when something requires high temps. Crucible* and cover These tongs are used for grasping or holding things like crucibles and flasks Crucible tongs* Used as a support for beakers when placed across a support ring. Wire gauze* Used to light a lab burner. Not a toy noisemaker during lab. Striker*
Used to grind solids into powders. Mortor and Pestle Used to hold test tubes for short periods of "gentle" heating. Test tube holder* Used to pour liquids into any container to prevent spills. If lined with filter paper it separates liquid from a solid. Filter funnel* Used for rinsing solids out of a container when filtering. Wash bottle* Used to transfer solids from their original container to a scale for weighing. Spatula* Used to close hoses by pinching them together. Hose clamps Triangle*: Used to hold crucibles when they are being heated. They usually sit on a ring stand Bunsen Burner*: Used for heating and exposing items to flame. Ring Stand*: Used to hold items being heated. Clamps* or rings* can be attached so that items may be placed above the lab table for heating by bunsen burners or other items.
Stir Rod* Used to stir solutions. Used to take temperature of solids, liquids, and gases. Use degrees C not F! Test tube stand*: holds test tubes while reactions happen in them or while they are not needed Disposable pipet*: moving small amounts of liquid from place to place, usually made of plastic. Test Tube Brush: to easily clean the inside of a test tube. Buret: Used in titrations to measure precisely how much liquid is used. Stopper: Prevents spills or vapors from evaporation. Can have holes for thermometers and for other probes that may be used. Bottle: Storage or mixing of solutions Paper towels*: Clean up up
Lab equipment is an important part of chemistry and science in general. In this page you will learn about lab equipment and its uses. (* = will use, ^ = might use) Beaker* Bottle Bunsen* Burner Name Description Picture Used to hold and heat liquids. Also use for Ballpark measurements Used for storage, for mixing and for displaying. Used for heating and exposing items to flame.
Buret Crucible* Erlenmeyer Flask Used in titrations to measure precisely how much liquid is used. Used to heat small quantities to very high temperatures. Used to heat and store liquids. The advantage to this flask is that the bottom is wider than the top so it will heat quicker because of the greater surface area exposed to the heat.
Evaporating Dish* Florence Flask Used to recover dissolved solids by evaporation. While it can be heated, it should not be used for "strong" heating. Used for heating subtances that need to be heated evenly. The bulbed bottom allows the heat to distribute through the liquid more evenly. Mostly used in distillation experiments.
Funnel* Spatula* Mortar and Pestle Paper Towels* Used to pour liquids into any container to prevent spills. If lined with filter paper it separates liquid from a solid. Used to transfer solids from their original container to a scale for weighing. Used to crush solids into powders for experiments, to better dissolve the solids. Used in almost every lab for clean-up.
Disposable Pipet* Ring Stand* Stir Rod* Used for moving small amounts of liquid from place to place, usually made of plastic. Used to hold items being heated. Clamps* or rings* can be attached so that items may be placed above the lab table for heating by bunsen burners or other items. Used to stir things. They are usually made of glass. Clamp Ring
Stopper (rubber or cork) Test tube Brush Test tube Holder* Test Tube Stand Prevents spills or vapors from evaporation. can have holes for thermometers and for other probes that may be used. Used to easily clean the inside of a test tube. Used to hold or transfer test tubes, especially if they are hot and untouchable. Used to hold test tubes while reactions happen in them or while they are not needed.
Thermometer* Used to take temperature of solids, liquids, and gases. Use o C not o F! Tongs* Striker Used to grasp or hold many different things such as flasks, crucibles, and evaporating dishes when they are hot. Used to light a lab burner. Not a toy noisemaker during lab.
Triangle* Volumetric Flask^ Watch Glass* Used to hold crucibles when they are being heated. They usually sit on a ring stand Used to measure one specific volume. They are mostly used in mixing solutions where a one liter or one half a liter is needed. Used to hold solids when being weighed or transported. They should never be heated.
Support Ring* Wire Gauze^ Graduated cylinder* When attached to the ring stand, this iron ring is used to support glassware above the lab table. Used as a support for beakers above lab table when placed across a support ring. Used to make accurate measurements of liquid volumes. The bumper ring is to prevent breakage if tipped over. Keep it near the top
Wash Bottle* Used for rinsing solids out of a container when filtering. For exact volume measurements of liquids. Pipet on the left is a Volumetric pipet. It has only one graduation for delivering one exact volume. Pipet on the right is a Mohr pipet. It has graduations for delivering any number of exact volumes. Volumetric Mohr
