Microbalances are a category of balances designed to measure small samples, typically in the sub microgram range. This instrument is considered the most accurate of all laboratory balances.
A micro balance consists of two components – one consisting of electronics and the other consisting of a specific mechanical measuring cell. Separation eliminates the effect of temperature on weight.
Use of microbalance
Microbalances are used in a variety of applications where small weight changes can make a big difference. These devices are commonly used in product checking out and quality assurance laboratories to ensure that strict production standards are met. Microbalances accurately measure the weight of objects of quite small mass to the order of millionths of a gram. In comparison, analytical balances are 100 times less sensitive. Therefore, the settling time of vibration isolation systems is an important criterion that affects the throughput of these devices.
How are the types of laboratory balances different?
When you need to choose a laboratory balance, you need to determine the preferred weighing range and accuracy:
What is an analytical balance?
Balance with an accuracy better than 0.1 mg.
Analytical balances are very sensitive and must be placed on a stable surface free from vibration.
What is water balance?
Moisture balance measures the quantity of water in a substance. This is particularly useful for food processing laboratories, as moisture content can be used as an indicator of the freshness and quality of sure foods.
What is the micro balance?
A microbalance can accurately measure the weight of very small objects with a resolution of one-millionth of a gram. This device is considered the most health-related. It is used in industry and research. Range 2 kg to 60 kg. Accuracy is a single gram or 0.1 gram.
What is Precision balance?
Precision balances are balances used daily in laboratories. Precision balances are available in a wide range from a few hundred grams to kilograms.
What are scales and balances?
A scale (sometimes called a weighing scale or weighing machine) was, and still is, an instrument for measuring the weight of an object. Balance measures the mass or gravity of an object, while scales measure weight or binding force.
Why are micro balances more sensitive than analytical balances?
A micro balance can accurately measure the weight of objects on a relatively small mass scale, such as one-millionth of a gram. In comparison, standard analytical balances are 100 times less sensitive. Microbalances are also very sensitive to drafts, dust, and thermal fluctuations.
Why are scales important?
Calibration of the balance or scale is critical to obtaining accurate weighing results. Ignoring this critical service activity turns measurement into guesswork. In other words, weighing with an unbroken scale is negligent. The accuracy of balances and scales becomes less and less reliable over time.
How do you measure analytical balance?
Place the weighing pan on the balance pan and close the door. Tap the control bar to tear the container. When the container is on the plate, the reading will be zero. This allows direct reading of the mass of the sample.
