stop watch

A handheld timepiece used in labs to precisely measure time intervals for experiments by starting, stopping, and resetting the timer.

air piston

use laboratories for automation, precise motion control, and powering various instruments and systems. They convert the energy from compressed air into either linear or rotary motion.

lab coat

protect against hazardous materials by creating a physical barrier for skin and clothing, providing an extra layer against chemical splashes and spills, and preventing the spread of contamination outside the laboratory.

platform balance

are used in labs to accurately weigh larger and heavier samples than typically handled by smaller analytical balances, such as bulk chemicals, powders, and larger items.

safety goggles

to protect against splashes, fumes, and impacts, even when not actively working, and remove them only after cleaning the workspace and exiting the room.

triple beam balance

are used for the precise measurement of mass for chemicals, reagents, and biological specimens, ensuring accurate experimentation

buret

is used for titration, a process of precisely measuring the volume of a solution (titrant) needed to react completely with another solution (analyte).

graduated cylinder

accurately measures the volume of liquids and solids

flint striker

In a lab setting, is primarily used to ignite a Bunsen burner.

heat resistant gloves

In a lab setting, are used for handling hot objects safely, such as removing items from autoclaves, ovens, or furnaces.

test tube brush

In a lab, a is a specialized tool with bristles on a wire handle, used to clean test tubes, cylinders, and other narrow glassware by removing residues, while also being suitable for cleaning bottles and flasks.

flask brush

A is a cleaning tool used in a laboratory to effectively scrub the inside of flasks and other glassware without scratching the surface. It has a long, flexible wire handle that allows it to reach into narrow necks and curved bottoms, which are common features of different types of laboratory flasks.

beaker brush

In a lab, a is a cleaning tool used for scrubbing the inside of beakers and other wide-mouthed glassware to remove residue and ensure the equipment is clean for future experiments.

gas jet (outlet)

In a lab, a provides a controlled supply of flammable gas, most commonly natural gas, to a burner for heating, sterilization, and other chemical processes

wire gauze

In a lab, is primarily used to support glassware over a heat source, like a Bunsen burner, and to evenly distribute heat to prevent glassware from cracking due to thermal shock. Made from woven metal wire, it often has a ceramic center to disperse the flame more effectively, creating a stable surface for beakers and flasks during heating and evaporation.

watch glass

In a lab, is used to evaporate liquids, hold solids for weighing, or cover beakers to prevent contamination while allowing some gas exchange. It can also serve as a surface for heating small amounts of substances, like watching for crystal or precipitate formation.

evaporating dish

In a lab, an is a heat-resistant, shallow container used to evaporate liquids to concentrate solutions or isolate solid precipitates. Its large surface area and design promote fast evaporation of excess solvents, leaving behind a non-volatile residue. Made from porcelain or glass, these dishes withstand heat from sources like Bunsen burners, allowing for separation of mixtures based on boiling points.

dropper

In a lab, a is a tool used to measure and transfer small, controlled amounts of liquid to prevent contamination and ensure precision.

scoopula

A is used in a lab to transfer solid chemicals and powders between containers accurately and efficiently. It is a type of spatula with a rounded tip and concave shape, ideal for retrieving small amounts of solids from bottles, transferring them to a balance for weighing, or moving them into another container for experiments

spatula (how many ends say it in your head)

In labs, are used to scrape, transfer, and apply substances like powders and pastes, as well as for mixing, sampling, and spreading materials. TWO ENDS!

glass stir rod

A is a versatile laboratory tool used for just stirring solutions.

conductivity tester

Measures the material's ability to transfer energy, both thermal (heat) or electrical

funnel

for pouring liquid or other substance through a small opening

rubber policeman

glass and rubber, used to scrape solids from containers

boiling chips

provide a surface that induces bubble formation and assures a smooth boil (aka promises a smooth boil)

mortar and pestle

used to grind up materials

beaker tongs and crucible tongs (how to tell the two apart as well)

Pick up and holds apparatus,

spring scale

tool used to measure force

filter paper

special paper used to separate solids from liquids

reagent bottle

Used to store chemicals

wash bottle

used to rinse various pieces of laboratory glassware

condenser tube

for cooling and condensing gases into liquid for mixing, reading, and holding chemicals (its the weird bong looking thing we saw in class)
