A mixdrive is essential equipment for lab use, and you will find a great number of models to choose from available in the market. Not all of them will be suitable for your laboratory application. Therefore, it is important to consider the types that will suit you carefully. Here are the important factors to put into consideration when choosing a stirrer.
Capacity
One of the biggest determining factors to consider when choosing
a suitable mixer is capacity. Surprisingly, some stirrers can hold some fairly
large volumes of a substance to mix. You need to factor in which substances you
are going to use the mixer to mix and their velocity. Choose a stirrer that can
handle volumes up to the maximum specified well.
Safety features
With any stirring application available on the market, a safety
measure is a primary consideration. You need to factor in the following when
choosing your mixdrive: speed ramping, whereby it should have a control button
to slowly ramp up the speed to avoid splashing of substances. Hot top warning
indicator, probe protection, current limit protection, high-temperature
setting, hot top warning indicator, and safety shield to offer
protection against spills and aerosols.
Temperature range
For a stirrer, you need to ensure that the temperature it can
generate can be higher enough for your application. It is important to note
that your sample size will not achieve the maximum temperature of your stirrer.
Therefore, you need a stirrer to provide a temperature above what you need your
sample to reach.
Sample viscosity
If you are working with a dense sample, you need to be more concerned about your stir bar. You need to factor in sample size, type of stir bar to use, and stirring speed. Get a unit that has greater magnetic to control the stir bar from spinning out.
