Analytical scales are one of the common laboratory instruments. Analytic scales function basically the same as the scales in general, which is to measure the mass of objects. Even so, analytical scales in the laboratory certainly have specific functions that cannot be found in ordinary scales. Anything?


Know Analytical Scales

Analytical balance or analytical balance including the most common laboratory instruments in addition to the microscope, centrifuge, water bath (water heater), and several other instruments. Analytical scales are usually used to measure masses of very light objects (approximately 0.1 mg). Mettler Toledo's analytical scales have a readability range between 0.005 mg and 0.1 mg and a capacity of up to 520 gr with limitations of 3-5 digits behind the comma.

Analytical scales have the main part in the form of plates. This part is used to hold the object whose mass will be measured. Smart Grid Weighing Pan is a tool to minimize the effects of air movement, this is an innovative solution in detecting and reducing electrostatic in the weighing process.

Generally, analytical scales have a transparent covering around the disk. This transparent protector serves to prevent dust from entering and being weighted in the dish.

Samples to be measured by the mass of the object with analytical scales must be at room temperature. The aim is to avoid the occurrence of natural convection of objects that can affect the accuracy of measurement results. Even so, when putting the sample, must be careful and slow.


Types of Analytical Scales

If differentiated by its use, there are several types of analytic scales commonly used in laboratories. There are analog analytic scales and there are also digital analytic scales. Hearing its name, you can already imagine what the difference is like between these two types of analytic scales.

Analog Analytical Scales

Analytic scales are still using the manual method. To measure the mass of an object, analog analytical scales still use gauge earrings or sliders. This slider can be shifted to adjust the size of the mass of the object. However, at this time analog analytical scales have begun to be abandoned because of their lack of accuracy.

Digital Analytical Scales

In addition to analog analytical scales, there are also digital analytical scales. Scales of this model are now widely used in laboratories. Its use is easy because the laboratory assistant simply places the sample object on a dish and the machine will display the measurement results in an easy-to-read number format. These scales are then divided into two types based on their calibration process:

1. Internal Calibration

This analytical scale requires an additional component, that is, weights to be able to verify. Weighs used must include low weight and high weight based on the range of capability of the tool to get precision.

Analytical scales from Mettler Toledo are equipped with automatic calibration capability, where every time a change in temperature occurs, the tool will make adjustments automatically.

2. External Calibration

Unlike the internal calibration, this calibration requires competent personnel to be able to carry out the calibration so as to obtain the linearity, accuracy, and precision that will be listed on each calibration certificate.

The Hyprowira Laboratory provides external calibration services performed by competent personalities from Mettler Toledo.


Analytical Scales Function in the Laboratory

Entered into the main discussion, what exactly is the function of analytical scales in the laboratory? As mentioned, the function of analytical scales is to measure the mass of objects (especially those which are very light).

These analytical scales are used to get more specific and accurate results on objects with a light mass (approximately 0.1 mg). Generally what is measured is a sample of chemicals that are included in the pro analytic (PA) category.

One example of the use of analytical scales is to weigh the exact dose of a chemical in a drug. With analytical scales, you can measure the mass carefully and precisely for each addition of certain chemicals that must be added to medicinal products.

The function of analytical scales in the laboratory is crucial. Without analytical scales, you will have difficulty getting accurate results when having to measure the mass of an object. With analytical scales, you can also get the right formula when you have to arrange products with high accuracy.


To guarantee accurate weighing, you can use a scale from Mettler Toledo which has a reading range between 0.005 mg to 0.1 mg, and a capacity of up to 320 g. Equipped with a patented Smart Grid Weighing Pan, which serves to minimize the effects of air movement, as well as innovative solutions for electrostatic detection and removal, Mettler Toledo scales also have Status Light, Level Control, and GWP Approved facilities, as well as easy data transfer and connection to devices peripherals via USB, RS232, and optional Bluetooth, and intuitive applications for efficient routine weighing. The design with a color TFT touch screen with clear icons and intuitive guidance allows users to operate analytical scales efficiently plus Quality assurance features help you comply with regulations and industry standards.
