24
Q

Use: examination of viruses
or internal ultrastructure in
thin sections of cells

A

TRANSMISSION ELECTRON (TEM)

25
Q

Uses a thin metal probe
that scans a specimen

A

SCANNING TUNNELING (STEM)

26
Q

Use: reveals bumps and
depressions of atoms on
surface of specimen

A

SCANNING TUNNELING (STEM)

27
Q

Measures the deflection
of a laser beam aimed at
the tip of a probe that
travels across the surface
of the specimen

A

ATOMIC FORCE MICROSCOPY

28
Q

Measures the deflection
of a laser beam aimed at
the tip of a probe that
travels across the surface
of the specimen

A

ATOMIC FORCE MICROSCOPY

29
Q

Use: visualization of
individual molecules and
atoms

A

ATOMIC FORCE MICROSCOPY

30
Q

Used when there is a need to
culture microorganisms and
for substances that must be
protected from contamination

A

SCREW CAPPED TUBES

31
Q

Used to make broth, agar
deep, and agar slant

A

SCREW CAPPED TUBES

32
Q

Used to detect production of
gas by microorganisms. An
inverted small tube is initially
filled with the solution in
which the microorganism is
to be grown.

A

DURHAM FERMENTATION TUBE

33
Q

Simpler than Durham tube.
Used also for observing
microorganisms perform
fermentation.

A

SMITH FERMENTATION TUBE

34
Q

used to make agar
plates for microbiology
studies

A

PETRI DISH

35
Q

Glassware calibrated for
precise volume.

A

VOLUMETRIC FLASK

36
Q

Used for measuring or
storing different
amounts of liquid

A

VOLUMETRIC FLASK

37
Q

Has a single graduation
that allows it to deliver
one specific volume
accurately

A

VOLUMETRIC PIPETTE

38
Q

serological or blow-out
pipettes have no 0ml
mark as that corresponds
to an empty pipette

A

SEROLOGIC PIPETTE

39
Q

Makes it easy to deliver
liquids, especially small
volumes, accurately and
precisely

A

PIPETTOR

40
Q

Has a disposable tip

A

PIPETTOR

41
Q

Used to observe
specimens for a long time
because they do not dry
up very quickly. Thus,
motility of an organism
can be observed.

A

HANGING DROP SLIDE

42
Q

AKA smear loop, inoculation
wand or microstreaker

A

INOCULATING LOOP

43
Q

used to retrieve and transfer
an inoculum from a culture of
microorganisms

A

INOCULATING LOOP

44
Q

mainly used to pick a single
colony (pure) and transfer in an
agar slant (stab and streak
method)

A

INOCULATING NEEDLE

45
Q
  • Test tube rack
  • Slant rack
  • Staining rack

Q

For drying specimens
and lab apparatus or
glassware

A

DRYING OVEN

52
Q

used for growing
bacterial cultures or
providing suitable
conditions for a
chemical or biological
reaction.

A

INCUBATOR

53
Q

It is used in the
microbiological lab for
incubations or enabling
chemical reactions to
occur at higher
temperatures

A

WATER BATH

54
Q

Storage for culture media

A

R.REFRIGERATOR

55
Q

Preserves the
morphological
characteristics of
microorganisms while
arresting their growth

A

REFRIGERATOR

56
Q

An enclosed, ventilated
lab workspace for safely
working with pathogens
requiring a defined
biosafety level
