| Analytical balances |
Analytical balances are precision instruments used in laboratories to measure masses with high accuracy. They are essential in many scientific fields, including chemistry, pharmacology, biological research and environmental analysis. Here is information about the usefulness, operation and some types of analytical balances used in laboratories:
Utility:
Accurate Mass Measurement:
Analytical balances are designed to provide extremely accurate mass measurements and are sensitive to small variations in weight.
Preparation of Solutions:
Used in the preparation of chemical solutions, where it is crucial to have the precise amount of each reagent.
Sample Analysis:
Used in quantitative analyses, such as determining levels in samples, especially in experiments that require high precision.
Weighing of Substances in Biological Research:
Applied in biological research to weigh substances, such as samples of DNA, proteins and biochemical compounds.
Operation:
Operation principle:
Analytical balances generally work on the single-arm or double-beam lever principle, where a pan is attached to a rod and the mass is determined by balancing the balance.
Calibration:
Before each use, the scale is calibrated using standard weights to ensure accurate measurements.
Controlled Environment:
Generally, analytical balances are used in controlled environments to minimize interference from air currents, vibrations, and other external factors that can affect accuracy.
Careful Handling:
Careful handling is crucial to ensure accurate results. They are often equipped with door systems to protect samples from external influences.
Common Types of Analytical Balances:
Electronic Analytical Balances:
They use electronic sensors to measure rod deflection and convert into mass readings. They are faster and can have advanced features, such as connectivity to computers.
Mechanical Analytical Balances:
They work based on mechanical principles of levers and counterweights. They are more traditional and can be used when extreme precision is not necessary.
Microbalances:
Designed to weigh very small quantities of substances, often in the microgram or even nanogram range.
Double Pan Scales:
They have two plates to accommodate samples and standard weights. They are used for comparison and calibration.
Precision Analytical Balances:
They offer a combination of high precision and load capacity. They can be used in various analytical applications.
Semimicro Scales Analysis:
Designed to weigh intermediate quantities between standard analytical balances and microbalances.
Portable Analytical Balances:
They offer mobility and are used in situations where the scale needs to be transported to different work locations.
The choice of type of analytical balance will depend on the specific needs of the laboratory, the application in question and the level of precision required. Each type of balance has its advantages and is selected based on sample characteristics and experimental requirements. |
