A

TRANSMISSION ELECTRON (TEM)

25
Uses a thin metal probe that scans a specimen
SCANNING TUNNELING (STEM)
26
Use: reveals bumps and depressions of atoms on surface of specimen
SCANNING TUNNELING (STEM)
27
Measures the deflection of a laser beam aimed at the tip of a probe that travels across the surface of the specimen
ATOMIC FORCE MICROSCOPY
28
Measures the deflection of a laser beam aimed at the tip of a probe that travels across the surface of the specimen
ATOMIC FORCE MICROSCOPY
29
Use: visualization of individual molecules and atoms
ATOMIC FORCE MICROSCOPY
30
Used when there is a need to culture microorganisms and for substances that must be protected from contamination
SCREW CAPPED TUBES
31
Used to make broth, agar deep, and agar slant
SCREW CAPPED TUBES
32
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.
DURHAM FERMENTATION TUBE
33
Simpler than Durham tube. Used also for observing microorganisms perform fermentation.
SMITH FERMENTATION TUBE
34
used to make agar plates for microbiology studies
PETRI DISH
35
Glassware calibrated for precise volume.
VOLUMETRIC FLASK
36
Used for measuring or storing different amounts of liquid
VOLUMETRIC FLASK
37
Has a single graduation that allows it to deliver one specific volume accurately
VOLUMETRIC PIPETTE
38
serological or blow-out pipettes have no 0ml mark as that corresponds to an empty pipette
SEROLOGIC PIPETTE
39
Makes it easy to deliver liquids, especially small volumes, accurately and precisely
PIPETTOR
40
Has a disposable tip
PIPETTOR
41
Used to observe specimens for a long time because they do not dry up very quickly. Thus, motility of an organism can be observed.
HANGING DROP SLIDE
42
AKA smear loop, inoculation wand or microstreaker
INOCULATING LOOP
43
used to retrieve and transfer an inoculum from a culture of microorganisms
INOCULATING LOOP
44
mainly used to pick a single colony (pure) and transfer in an agar slant (stab and streak method)
INOCULATING NEEDLE
45
- Test tube rack - Slant rack - Staining rack
RACKS
46
Uses dry heat to sterilize heat-stable materials
HOT AIR STERILIZER
47
For sterilization of media and other materials affected by moisture
HOT AIR STERILIZER
48
Uses moist heat or steam under pressure
AUTOCLAVE
49
For sterilization of media and other materials affected by moisture
AUTOCLAVE
50
Not sterile and cannot be used to sterilize culture media
DRYING OVEN
51
For drying specimens and lab apparatus or glassware
DRYING OVEN
52
used for growing bacterial cultures or providing suitable conditions for a chemical or biological reaction.
INCUBATOR
53
It is used in the microbiological lab for incubations or enabling chemical reactions to occur at higher temperatures
WATER BATH
54
Storage for culture media
R.REFRIGERATOR
55
Preserves the morphological characteristics of microorganisms while arresting their growth
REFRIGERATOR
56
An enclosed, ventilated lab workspace for safely working with pathogens requiring a defined biosafety level
