BASIC Flashcards
the study of all living organisms that are too small to be visible
with the naked eye. This includes bacteria, archaea, viruses,
fungi, prions, protozoa and algae, collectively known as
(MICROBES).
Microbiology
vaccine against smallpox
Dr. Edward Jenner
discovery of penicillin
Alexander Fleming
who identified the link between papilloma virus and cervical cancer
Dr. zur Hausen
calculates weights based on the force
required to balance the mass of a sample rather than utilizing
actual masses
Analytical balance
machine that uses steam under pressure to kill harmful
bacteria, viruses, fungi, and spores on items that are placed
inside a pressure vessel
Autoclave
used to heat substances, to combust substances, and to
sterilize objects on high heat.
Bunsen burner
laboratory device that is used for the
separation of fluids, gas or liquid, based on density
Centrifuge
device that is frequently used to count
bacterial or other microorganism colonies on a plate that
contains a gelled growth medium
Colony Counter
testing equipment that are used to
preserve and store food products, medical equipment, blood
samples, medicines and injections, etc. for a long period of time.
Deep Freezer
essential laboratory equipment that uses
to dry heat (hot air) to sterilize laboratory objects and samples.
This type of sterilization is also known as dry heat sterilization
Hot Air Oven
referred to as a system that provides
continuous air flow that is uniform in both direction and velocity
-facilitate unidirectional air flow in a confined space
Laminar Air Flow
device widely used in laboratories and
consists of a rotating magnet or a stationary electromagnet that
creates a rotating magnetic field.
Magnetic Stirrer
instrument used to measure hydrogen ion activity in solutions - in other words, this instrument measures
acidity/alkalinity of a solution
pH Meter
laboratory equipment made from a container
filled with heated water. It is used to incubate samples in water
at a constant temperature over a long period of time
Water Bath
device used to grow and maintain
microbiological cultures or cell cultures
-maintains optimal temperature, humidity and other conditions such as the CO2 and oxygen content of the atmosphere inside
Incubator
instrument used for detecting the
presence of any light-absorbing particles dissolved in a solution
and for measuring the concentration of those particles
Spectrophotometer
instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by
the unaided eye.
Microscope
flat, shallow dish made of glass or plastic with a suitable lid
-used to culture different types of
cells, including bacteria and molds. It often contains a nutritional medium on which the cells can grow
Petri Dish
simple tool used mainly by
microbiologists to pick up and transfer a small sample of microorganisms called inoculum from a microbial culture, e.g. for streaking on a culture plate
Inoculation Loop
used to contain liquids and for mixing,
heating, cooling, incubation, filtration, storage, and other liquidhandling processes
Erlenmeyer Flask
used to hold liquid or solid samples or as a container for reactions. They are also used to collect filtrates from filtering operations as well as liquids from titrations
Beaker
common piece of laboratory equipment used to measure the volume of a liquid.
Graduated Cylinder
used to grind up solid chemicals into
fine powder and crush solids into smaller pieces.
Mortar & Pestle
