The required water quality should be selected according to the analytical method and laboratory application.
8. Laboratory Centrifuges
Laboratory centrifuges separate components of samples using centrifugal force. They are commonly used in research, pharmaceutical, biological, chemical, and testing laboratories.
Benchtop centrifuges can be suitable for laboratories where space and sample-processing requirements need to be considered.
9. Laboratory Shakers and Mixers
Laboratory shakers and mixers are used to mix, agitate, or prepare samples. Different types, such as orbital shakers, reciprocating shakers, vortex mixers, and overhead stirrers, are available for different applications.
The appropriate equipment depends on sample characteristics, mixing requirements, speed, capacity, and application.
10. pH, Conductivity and Water Quality Meters
Water and solution testing often requires measurement of parameters such as pH and conductivity. Laboratories may use pH meters, conductivity meters, dissolved oxygen meters, turbidity meters, and water quality meters depending on the testing requirement.
