Quality, Accuracy and Repeatability

The Gibertini laboratory balance is a measuring instrument with a high degree of accuracy, speed, safety and precision (resolution from 0.001 mg to 1g with a range from 1g up to 10kg). Versatile and flexible, all Gibertini electronic analytical balances are equipped with magnetic compensation cells that guarantee their quality and high repeatability. They are equipped with internal motorized calibration for rapid and constant calibration of the instruments. For all Gibertini analytical balances certified sample weights and masses are available for correct calibration.

All Gibertini laboratory balances are manufactured according to the "Made in Italy" high quality standards

Frequently Asked Questions

Why is it better to certify an instrument?

Accredia LAT certified calibration is an operation performed by accredited technicians and provides the results obtained at the time of calibration (uncertainty, repeatability, minimum weight) :

  • to assess compliance with laboratory standards for passing internal quality control (eg CQI) or external audits;
  • to guarantee reliable measurements that are compatible with any laboratory (VEQ analytical quality control, Ring Test);
  • to apply correct tolerances on the products avoiding waste or reworking;
  • to identify instruments that are no longer suitable for the production process due to the accumulation of stress.
When is it necessary to calibrate the instrument?

Analysis Laboratory instruments require constant "calibration", carried out by measurement samples defined as "reference samples". Gibertini Laboratory balances can be equipped with an internal calibration system or with a certified calibration masses .

Instrument calibration is fundamental process for the correct and repeatable operation of the analytical weighing system. It is a quality system procedure designed to guarantee the accuracy of the measurement results. Checking the accuracy of an instrument means ensuring that it remains stable between one calibration and the next, and that the certified accuracy remains as constant as possible over time.

The calibration frequency of the weighing instruments is determined :

  • from the tolerance on the product, generally the lower it is (valuable product), the more frequent the calibrations should be
  • from the number of weighs; the more the instrument is used, the greater the frequency of the calibrations
  • from the Environment; dust, vibrations, drafts and temperature variations affect the correct behavior of the instrument
Determine the density of solids and liquids with Gibertini laboratory balances?

Density determination is an important qualitative parameter for both raw materials and finished products. Various techniques allow you to accurately determine the density of solid, viscous and liquid materials, such as metals, plastics, chemicals, lubricants and foods.

There are a number of standards and norms relating to the determination of density. Some of the most common are :

  • ISO 1183-1: plastic; methods for determining the density of non-cellular plastics
  • OIML G 14: Density determination according to the OIML
  • ASTM-D-792: Standard Density and Specific Gravity Verification Methods

The gravimetric density determination is suitable for solids and liquids. How is density determined with a Gibertini balance?

  • Weigh the sample on the weighing pan (in air)
  • Then immerse the sample in the liquid placed under the balance
  • The balance displays the density

For samples with density less than 1, the spherical cage is used to contain the sample

Determine the density in plastics

The density of a plastic sample can change due to the change in temperature, crystallinity, loss of plasticizers, solvent absorption.

It is important to determine the density in plastics for the following reasons:

  • To determine the characteristics of the material
  • To follow material changes
  • To identify uniformity between different samples of the same material
  • To calculate the cost-weight of the material
Does the density calculation meet the ISO 11873-1 standard?

Yes. ISO 1183-1 compliance requires a balance with a resolution of 0.1 mg or less and a sample with a mass of at least 1 g. CRYSTAL and ETERNITY balances with 0.1mg resolution and high repeatability can be used for the calculation of the sample density according to ISO1183-1
