Three things to ask about when buying a UV-Vis instrument in particular

As volumes can vary from sample to sample, purchasing the right size of stirrer or mixer is one important consideration

For laboratories with high sample volumes and an increased need for faster turnaround times, automating the titration process may be the way to go

Different processes require varying amounts of vacuum or flow to operate properly

Different labs have different water requirements

Knowing the history of the pre-owned instrument you’re purchasing is very important

Understanding the types of samples being handled will determine the type of BSC required

For samples and processes which have large or varying volumes, a floor standing model may be a better fit

The sample matrix can have an effect on the type of surface chemistry that is applied to the column being used

The number of workers utilizing the incubator and the scope of tests being run can strongly affect the type of CO2 incubator used

The costs of running the unit, as well as sample type, are key determining factors when purchasing

Automated liquid handlers come in a seemingly endless variety of configurations, with many different specifications
