Used to secure glassware to a ring
stand
utility clamp
Used to prepare solutions to an
accurate volume
volumetric flask
Used to measure small amounts of liquid very accurately. Never pipet by mouth! Use pipetting aids
volumetric pipet
Used to rinse pieces of glassware
and to add small quantities of water
wash bottle
Used to hold solids while they are
being weighed or to cover a beaker
watch glass
Used to support a container, such as a beaker, on a ring stand while it is being heated . May have a fiberglass or ceramic center
wire gauze
Neutralize acids with _____________ (soda ash) or __________ (baking soda)
sodium carbonate (soda ash)
sodium bicarbonate (baking soda)
Bases can be neutralized with ___________ or ___________
citric acid or ascorbic acid
EQUIPMENT FOR MEASURING MASS
triple beam balance
analytical balance
electronic balance
used to measure masses very precisely
triple beam balance
riders
balance pointer
pan
base
counter weight
beams
extremely accurate laboratory balances used to precisely measure the mass of an object. It can read up to 0.00001 grams (0.01 mg).
analytical balance
Employed in laboratory settings to determine the mass of substances.
It is developed to offer precise and dependable measurements, usually with a readability of up to four decimal places or higher.
electronic balance
EQUIPMENT FOR MEASURING VOLUME
erlenmeyer flask
pipette
syringe
Used as distillation receiving containers, to store separate layers in an extraction, as reaction flasks, to heat solvent for crystallizations, as a crystallization flask, and so on.
erlenmeyer flask
measure out or transfer small quantities of liquid, in volumes of milliliters (mL) or microliters (μL).
pipette
used in research labs for numerous activities including injection of gasses or liquids into chromatographs, chemical apparatus, or animals.
syringe
EQUIPMENT FOR MEASURING TEMPERATURE
thermocouple thermometer
liquid in glass thermometer
temperature-sensitive sensors made composed of two metal wires that have been soldered together, they are integrated into thermal processing equipment and laboratory heaters.
used to obtain internal temperatures as an electrical value.
Thermocouple Thermometer
simplest and most widely used kind of temperature monitoring tool is a liquid-in-glass thermometer.
provides reasonably accurate readings between -200 and 600°C.
Liquid in glass thermometers use the change of volume to estimate the temperature.
Liquid in Glass Thermometer
EQUIPMENT FOR STORAGE/TRANSFER/CARRIAGE OF REAGENTS
chemical storage cabinets
laboratory refrigerator
centrifuge
To separate incompatible chemicals from one another and to ensure safe
Chemical Storage Cabinets
Storing temperature-sensitive materials, such as biological samples, chemicals, and reagents
Laboratory Refrigerator
separates heterogeneous mixtures into their various components/ substances
Centrifuge
Used to perform chemical reactions, uniformly heating samples/ solutions, etc.
hot plate
Measures how acidic or alkaline a solution is by checking hydrogen ions.
Gives a value between 1 and 14, showing the solution’s acidity or alkalinity
pH Meter
Heats samples with controlled high or low heat, sterilizes and offers a steady flame by mixing gas and air.
Reaches temperatures up to 1,200 Celsius using natural gas like methane or liquefied petroleum gas.
Bunsen Burner
Used in a flame test
Transfer of tools that move sample of organic sample onto sterile plate
platinum wire
- crucial in laboratories for exact liquid measurement and distribution.
- accurately determine unknown solution concentrations.
burette
Used to accurately measure the density of a liquid.
pycnometer
is a piece of laboratory glassware used for precise measurement of a solution’s volume.
calibrated to deliver a certain volume of a solution
volumetric pipette
measures the specific gravity of a liquid
hydrometer
extraction of lipid from a solid material
extract specific compounds from solid sample using a continuous solvent extraction process
soxhlet
condense vapors, turning them into liquids by cooling them down
condenser
more accurate in measuring and transferring liquid volumes
calibrated all the way to the tip
serologic pipette
