1. Laboratory Equipment

2. Laboratory Equipment Spot Plates
ceramic plates divided into small wells or depressions.
used for qualitative analysis
used to perform reactions on a very small amount of materials.
white plates – color formations are seen easier
black plates – white precipitates are seen easier
Spot Plates

3. Laboratory Equipment Burets
used to deliver solution in precisely-measured, variable volumes.
used primarily for titration, to deliver one reactant until the precise end point of the reaction is reached.
Double buret clamp
Buret
Support stand
Buret clamps
Thermometer clamp

4. Laboratory Equipment Wire Gauze Ring support
used to support beakers, flasks, etc. on a ring stand.
recommended for 400ml and larger glassware.
Although most laboratory glassware is Pyrex, Bomex or similar heat resistant glass, none of them should ever be in direct contact with a flame. The only exception is a Test Tube and even that should be kept moving in & out of the flame. The proper way to heat materials in laboratory glassware (when using an open flame) is to place a Ceramic Center Wire Gauze between the flame and glassware.
Bunsen Burner
used to heat substances

5. Laboratory Equipment Crucible Clay Triangle
Used to hold small amounts of chemicals during heating at high temperatures.
The lid covers the bowl so nothing escapes, or to keep oxygen out of the reaction.
used to grasp and take a hot crucible out of a fire or furnace, or to move a crucible.
Crucible Tongs

6. Laboratory Equipment Evaporating Dish
Use an evaporating dish to evaporate a liquid. The solution is boiled using a Bunsen burner and the liquid is driven off as steam (vapour) leaving behind the solid.
no lid

7. Laboratory Equipment Erlenmeyer Flask (250mL) Beaker (600mL)
Volumetric Flask (250mL)
Erlenmeyer flasks and beakers are used for mixing, transporting, and reacting, but not for accurate measurements.
The volumes stamped on the sides are approximate and accurate to within about 5%.
used to make up a solution of fixed volume very accurately.
± 0.2 mL level of uncertainty

8. Laboratory Equipment Glass Stir Rod Glass Funnel Graduated Cylinder
used to mix or combine two or more substances in a test tube or a beaker
used to transfer liquids to another container and when filtering out solids.
used to measure out accurate volumes of liquid.

9. allows to draw liquid into a pipet and release it from the pipet.
3 Way Bulb
Volumetric Bulbs
allows to draw liquid into a pipet and release it from the pipet.
Volumetric Pipets
A three-way bulb is often chosen because it reduces the possibility of contact with the liquid, and any liquid drawn into a pipet can easily be held in the pipet until delivery. The three valves provide a convenience not found in the standard bulb.
used to transfer a specific volume of liquid solution to a container.
Single graduation: 1-, 5-, 10-, 25-, 50-, and 100-mL
Stand Bulb

10. Laboratory Equipment Watch Glass
used to hold or weigh out a small amount of solid
used to cover a beaker
provides a surface to evaporate a liquid
allows closer observation of precipitates or crystallization, and can be placed on a surface of contrasting color to improve the visibility overall.

11. Laboratory Equipment Gas-Collecting Tube Gas-Collecting Jar
Rubber Tubing
used for collecting a gas and qualitative analysis.
to contain a gas or for reactions.
used for collecting a gas and quantitative analysis.

12. Laboratory Equipment Test tube brush Used to clean a test tube
Test tube rack
Test tube
Test tube tongs
used to hold a test tube during heating or while still hot.
used to hold and store test tubes
a small container for solutions and reactions

13. usually provide less sensitive measurement of mass
Triple Beam balance
usually provide less sensitive measurement of mass
Analytical Electric balance
used to measure the mass of reagents or laboratory equipment.
wide range of accuracy depending on the intended use.
Point out the draft shield, tare button, digital displace, balance pan
used when a high degree of accuracy is needed for the measurement.

14. Centrifuge
used to separate a solid from a solution quickly
A centrifuge is used for small-scale separations; typically the volume is less than 5 mL. Larger volumes of mixtures can be separated by filtration.

15. Thermometer
used to measure the temperature of solids, liquids, or gases
contains a liquid (usually mercury or an alcohol solution) in a reservoir. As the temperature increases, the volume increases.
Celsius, Farenheit, or Kelvin, therefore it is important to note which scale the thermometer is calibrated for

16. Laboratory Equipment
Eyepiece Lens: the lens at the top that you look through. They are usually 10X or 15X power
Objective Lens: Usually you
will find 3 or 4 objective lenses on a microscope. 4X, 10X, 40X and 100X powers. When coupled with a 10X (most common) eyepiece lens, we get total magnifications of 40X (4X times 10X), 100X , 400X and 1000X.

17. Weighing Boats
used for weighing liquids or solids on a balance.
advantages:
bendable, easy transfer of measured samples.
smooth surface and rounded corners provide for easy removal of powered and granular samples.
Controllable pour off with recessed corners.
Resistant to dilute acids, alcohol and bases

18. Filter Paper
Used to filter a substance out of a solution or an impurity out of a liquid. Examples include: filtration of extracts, oils, beer, syrups etc
Used for qualitative and quantitative analysis
Filtrate – the liquid that has been passed through the filter.
Residue, retentate, or filtrand – solid remaining in the filter paper.
