38. MODERN LABORATORY TOOLS
AND THEIR USES
 pH meter is an instrument
used to measure acidity or
alkalinity of a solution -
also know as pH.
 pH is the unit of measure
that describes the degree
of acidity or alkalinity. It
is measured on a scale of
0 to 14.

39. COLONY COUNTER
 a device that is
frequently used to
count bacterial or other
microorganism colonies
on a plate that contains
a gelled growth
medium.

40. CALORIMETER
 is a device used
to measure the
amount of heat
involved in a
chemical or
physical process.

41. GALVANOMETER
 A galvanometer is one of
the instruments for
measuring electrical
current par excellence.
This device is used on
electrical circuits to
know and measure the
intensity and direction of
electrical current.

42. VOLTMETER
 The voltmeter is a
measurement device
used to measure
voltage in electrical
circuits or electronic
devices. It is
commonly employed
to measure the voltage
across a circuit or
component, typically
expressed in volts.

43. OSCILLOSCOPES
 Oscilloscopes (or scopes) test and display voltage
signals as waveforms, visual representations of the
variation of voltage over time.

44. MICROPIPETTE
 A micropipette is a
common laboratory
instrument used to
measure small amounts of
liquids with a volume
range between 1 and
1000µl.
 A micropipette is also
used to transfer a precise
amount of fluid from one
container to another.

45. LABORATORY SENSORS

46. LABORATORY SENSORS
 Laboratory sensors are used for many different
applications and must show excellent accuracy,
provide fast readings, and endure long periods
without use.

47. ACTIVITY
 If you were a laboratory tool, what would
you be? And why?
 Write your answer in a ½ crosswise sheet of
paper.
