What Is an Analytical Balance Used for? RADWAG Analytical Balances: Functions and Applications
An analytical balance is a measuring device that is characterized by very good repeatability as well as high both readability and resolution. What is an analytical balance used for? What functions and applications does it have?
What Is an Analytical Balance Used for? Applications
An analytical balance is intended for weighing small masses. This laboratory balance is used precisely in laboratories, including medical, pharmaceutical, biological, chemical and physical ones.
Analytical Balance – Functions
Analytical Balance Adjustment
Balance adjustment is aimed at correcting the indication error, that is, maximizing the precision of the balance. It involves comparing the weighing result of an internal balance weight with its previously determined value.
The best solution is 2-Point Adjustment, which helps:
- Achieve the highest measurement precision within the whole weighing range
- Minimize linearity errors
- Eliminate errors due to ambient conditions change and gravity coefficient.
Analytical Balance with an Integrated Antistatic Ionizer/ External Antistatic Ionizer
An analytical balance equipped with an antistatic ionizer neutralizes the electrostatic charge of the sample. If the balance additionally has an automatically open weighing chamber, the ionizer will neutralize the effect of charges on each weighing process, so each time the chamber is opened.
The electrostatic charge of the sample may prevent it from being weighed. The built-in ionizer will allow the sample to be weighed because it will neutralize this charge. The inside of the weighing chamber covered with a special antistatic layer will have a similar effect.
The external ionizer works on the same principle as the integrated one.
Analytical Balance Weighing Chamber
RADWAG analytical balances have a manual or automatic weighing chamber. You can open the automatic one using gestures thanks to infrared (IR) sensors. Non-contact opening and closing of the weighing chamber eliminates any vibrations that interfere with the measurement, allows you to define the degree of opening of the door and improves the work ergonomics.
An issue also worth noting is the quick and tool-free disassembly of the weighing chamber. This makes it much easier to clean as well as transport and install the balance in special weighing rooms, such as a glove box or laminar chamber. The easily removable weighing chamber is found in all RADWAG analytical balances.
Analytical Balance Levelling
A correctly levelled balance translates into precise and repeatable readings. RADWAG analytical balances can be levelled:
- Manually
- Semi-automatically (LevelSENSING System)
- Automatically (Reflex Level System, or auto-levelling).
When manually levelling the balance, the level indicator placed on the front of the balance allows you to quickly control the correct levelling. During semi-automatic levelling, the balance prompts the user how to adjust the level of the device; this means that semi-automatic levelling implemented by LevelSENSING System is more user-friendly and less time-consuming than the manual one. The most convenient and the fastest is auto-levelling, which not only guarantees the ideal position of the measuring system and the most precise measurement results, but also alerts when the balance is out of level. In addition, the fact that the balance is correctly levelled is confirmed in the calibration report, which is a prerequisite for the use of the balance in the pharmaceutical industry, for example.
