Different luminometers have different specifications and features that are going to have an impact on productivity and result quality.
Tube luminometers read samples in transparent tubes, that are introduced individually in the measurement chamber. Reagents can be dispensed either manually or using injectors.
Advantages:
Disadvantages:
As a result tube luminometers are a good option to determine a few samples per session or as an additional luminometer to verify weak samples.
Microplate luminometers perform a sequential measurement of samples placed in the wells of an opaque microplate, most often 96-well microplates. There are usually one of more injectors for reagent addition.
Advantages:
Disadvantages:
Sample number tends to increase progressively in most fields of application, so microplate luminometers are the instruments of choice in most laboratories.
In addition to the kind of luminometer, there are other factors to be considered. Any good luminometer needs to have:
There are other features that can be needed or convenient:
There are currently instruments that can be used as luminometer, spectrometer and fluorometer, but they have a few disadvantages that have to be considered:
Taking everything into account, it is usually better to have a good instrument of each type.
These are the main points to be considered. For more information, contact us.
