UNIT 2: EQUIPMENT Flashcards
1
Q
- Used when there is a need to
culture microorganisms and
for substances that must be
protected from contamination - Used to make broth, agar
deep, and agar slant
A
SCREW CAPPED TUBES
2
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
3
Q
- Simpler than Durham tube.
Used also for observing
microorganisms perform
fermentation.
A
SMITH FERMENTATION TUBE
4
Q
- used to make agar
plates for microbiology
studies
A
PETRI DISH
5
Q
- Glassware calibrated for
precise volume. - Used for measuring or
storing different
amounts of liquid
A
VOLUMETRIC FLASK
6
Q
- Has a single graduation
that allows it to deliver
one specific volume
accurately
A
VOLUMETRIC PIPETTE
7
Q
- serological or blow-out
pipettes have no 0ml
mark as that corresponds
to an empty pipette
A
SEROLOGIC PIPETTE
8
Q
- Makes it easy to deliver
liquids, especially small
volumes, accurately and
precisely - Has a disposable tip
A
PIPETTOR
9
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
10
Q
- AKA smear loop, inoculation
wand or microstreaker - used to retrieve and transfer
an inoculum from a culture of
microorganisms
A
INOCULATING LOOP
11
Q
- mainly used to pick a single
colony (pure) and transfer in an
agar slant (stab and streak
method)
A
INOCULATING NEEDLE
12
Q
- Test tube rack
- Slant rack
- Staining rack
A
RACKS
13
Q
- Uses dry heat to sterilize
heat-stable materials - For sterilization of media
and other materials
affected by moisture
A
HOT AIR STERILIZER
14
Q
- Uses moist heat or steam
under pressure - For sterilization of media
and other materials
affected by moisture
A
AUTOCLAVE
15
Q
- Not sterile and cannot
be used to sterilize
culture media - For drying specimens
and lab apparatus or
glassware
A
DRYING OVEN
