Most commonly used in the clinical laboratory with aerosol
Air displacement
Without aerosol
Positive displacement
Used in bacteriological purposes and serial dilutions
Displacement dilutor
Equipment used for measuring mass
Analytical balance
Classes of balance:
- Number of pans (single or double)
- Mechanical or electronic
- Operating ranges
Used to separate the components of the blood
Centrifuge
Most commonly used: centrifuges
Fixed-angle head
Swinging-bucket type
Tubes are position with angle
Fixed-angle head
Analytes travel fast to reach the bottom of the tube
Fixed-angle head
Sediments separates easily at the bottom
Fixed-angle head
Horizontal position of the tubes
Swinging-bucket type/horizontal centrifuge
Analytes travels far to reach the bottom of the tube
Swinging-bucket type
Pellets are tightly glued to each other
Swinging-bucket type/ horizontal centrifuge
Do not dislodge easily
Swinging-bucket type/ horizontal cetrifuge
For calibration: centrifuges
Tachometer
