Lab Equipment Power Point

Lab Equipment – One of the basic
tools for Scientists to explore and
discover.
Beaker
 a flat-bottomed
cylindrical container,
usually with a pouring
lip, to measure, mix, and
prepare liquids.
Test Tube
 a hollow cylinder of thin
glass with one end
closed, used for
experiments in labs.
Flask
 a bottle, usually of glass,
having a rounded body
and a narrow neck, used
especially in laboratory
experimentation.
Graduated Cylinder
 a narrow, cylindrical
container marked with
horizontal lines to
represent units of
measurement and used
to precisely measure the
volume of liquids.
Microscope
 an optical instrument
having a magnifying lens
or a combination of
lenses for inspecting
objects too small to be
seen or too small to be
seen distinctly and in
detail by the unaided
eye.
Test Tube Holder
 A plastic holder used to
hold test tubes or dry
them.
Magnifying Glass
 lens that produces an
enlarged image of an
object.
Hot Hands
 A set of protective hand
wear to use for hot lab
equipment.
Microscope Slide and
Cover Slip
 A glass or plastic
rectangular slide that is
used for specimens to be
looked at under a
microscope.
 A Cover Slip is used to
place over the specimen
on the Microscope Slide.
This holds it in place.
Pipette or Dropper
 a slender graduated tube
used in a laboratory for
measuring and
transferring quantities of
liquids from one
container to another.
Bunsen Burner
 a type of gas burner,
commonly used in
chemical laboratories,
with which a very hot,
practically nonluminous
flame is obtained by
allowing air to enter at
the base and mix with
the gas.
Goggles
 large spectacles
equipped with special
lenses, protective rims,
etc., to prevent injury to
the eyes from flying
objects, bubbling liquid,
or any other potential
threat in the lab.
Glass Stirring Rod
 A glass, cylindrical-like
stick that is used to mix
solutions in a beaker.
Also referred to as a
“Swizzle Stick”
Triple Beam Balance
 A triple beam balance is used to read the mass of
items. A triple beam balance has three beams: one
with 100 gram increments, 10 gram increments, and 1
gram increments.
 First make sure to calibrate the scale so that it reads
zero when nothing is placed on the pan, with all
weight to the left.
KNOW YOUR LAB
EQUIPMENT
 Study your notes and drawings on the lab equipment.
 This is so vital when performing labs and reading
procedure.
Let’s get to know the Microscope!
Science – 7th
Parts of a Microscope
 1. Eye Piece/Ocular- the piece that is looked through,
has a power of 10.
 2. Body Tube- skinny tube attached to the eye piece
that allows light to shine from the light source.
 3. Nose Piece- rotates the objective lenses
 4. Objective Lens (high, medium and low) used to
magnify the specimen on the stage.
 High power (longest lens = 40X)
 Medium power (middle lens = 10X)
 Low power (shortest lens = 4X)
Parts of a Microscope
 5. Stage- the slide is placed here.
 6. Stage Clips- holds the slide in place
 7. Aperture- hole in the stage that allows light to pass
through the specimen.
 8. Diaphragm- thin disk below the stage that adjusts
the amount of light needed.
 9. Legs/Base- holds the entire microscope up.

 10. Light Source- provides light to see the object.
 11. Course Adjustment- large knob that brings the
stage closer to the objectives. Focuses the specimen.
 12. Fine Adjustment- smaller knob that fine tunes the
image.
 13. Arm- attaches the upper portion of the microscope
to the base.

 14. Slide- the rectangular piece that holds the
specimen.
 15. Cover Slip- the plastic square piece that covers the
specimen.
Microscope Rules
 1. When carrying the microscope you must carry it with the

ARM and the BASE.
2. The microscope must always be stored with the lowest
powered objective in place.
3. When bringing an object into focus you must use the
lowest powered objective and the course adjustment.
4. ONLY use the FINE adjustment on the highest powered
objective.
5. Lenses should only be cleaned with lens paper.
6. The whole microscope must be kept away from the edge
of the lab table.
Creating a wet mount slide




1. Obtain a slide
2. Place the specimen on the center of the slide
3. Place ONE or TWO drops of water ON the specimen
4. Take the corner of the cover slip and place it near the
drop of water and CAREFULLY lower the cover slip on to
the water and specimen.
 **IF you see perfectly round, white circles when looking
through the eye piece THEN you are observing air bubbles.

 ** Slides and cover slips may be cleaned with water and a
paper towel.
