When absolute and precise measurement for small samples is required, the best possible solution is found in analytical balances. Far from just basic laboratory and weighing equipment, these devices, most which will be electronic, are the perfect addition for devices and equipment when precision is a critical factor.
The key factor to keep in mind when choosing any of the options or models in analytical balances is the precision they offer. These balances are typically exclusively used in laboratories and testing facilities because they are capable of measuring even very small changes in the weight of a sample.
With a focus on the very small sample size, the entire balance is set up very different than a general lab or chemistry type of balance. They have a full enclosure around the weighing platform to prevent any loss of the sample and to also ensure there is no dust or debris that can become collected on the platform. This type of protection, which is actually called a draft shield, will also prevent any slight breeze in the room from impacting the measurement of the sample on the scale.
It is important to consider several factors when using analytical balances. The actual sample that is being weighed has to be at room temperature. Even the slight energy exchange between the air within the draft shield and the sample can create slight movements in the air that may impact the reading on the scale.
Different scales will offer a variety of features to consider. Important features to have in any lab can include the option to easily adjust to different weighing units, actual chambers designed for taller beakers and flasks as well as specific filters that can easily be engaged through the front control panel for highly accurate weights under any conditions.
