The HR-AZ series of compact analytical balances utilises our proven A&D sensor technology to deliver superior performance to all users with fast, accurate measurements. The HR-AZ range has 0.1 milligram to 10 micrograms readability and is covered by our Industry leading 5 years warranty.
Static electricity, while often overlooked, can be a fatal source of error in precise weight measurements. The BM Series will help you perform sometimes-tricky analytical weighing with simplicity and accuracy, including the elimination of static electricity.
The new GX-M / GF-M Series is our latest high-capacity balance with precision and safeguards against various “Accidents”. The new GX-M/GF-M series is designed to provide excellent protection from workplace mishaps like liquid spills and impact shocks therefore preventing downtime while also guaranteeing maximum accuracy and productivity.
Density Balance: The AD-1653 or AD-1654 is combined with analytical or precision balances to easily measure the density of a solid or liquid sample based on the Archimedes’ principle.
There are several versions of laboratory balances, including:
● Precision balances – also known as top-loading balances – offer the ability to measure the smallest size of mass with accurate results.
● Analytical balances offer a much wider range of readability for analytical purposes. Analytical balances can measure from 0.002 mg to 0.1 mg – perfect for all types of analytical workflows.
● Moisture analyzers use a heating unit built with infrared technology and a weighing unit to analyze and determine the moisture content of various samples.
● Micro balances – also known as an ultra-microbalance – is built to offer high precision with the weighing of sample quantities as low in weight as 30 microgram (μg).
● Mass comparators allow operators to take measurements of fractional weight changes of objects of various sizes and properties.
Applications for Weighing in the Laboratory
Analytical laboratory scales and balances are used for a variety of applications across many industries. The types of measurements that highly-accurate laboratory balances can complete include:
● Measuring Density
● Preparing Titration Samples
● Moisture Content Determination
● Emissions Testing – Gravimetric Determination of Particulate Matter
● Trace Metal Analysis: Sample and Standard Preparation
● Pesticide Residue Testing – Accurate Standard Preparation
● Buffer Preparation
A&D Weighing offers four levels of laboratory scales and balances offering varying measurement abilities and readability capabilities, including:
● PREMIUM | The highest-quality analytical and precision balances with advanced capabilities for the ultimate weighing solution.
● ADVANCED | This range will suit those who need more advanced features than that found in standard balances.
● STANDARD | Perfect for mid-level laboratories and companies, these scales offer industry-standard measurements at an affordable price.
● ENTRY | Entry-level balances and scales offer quality measuring for schools, training programs, and other budget-minded organizations.
What is an analytical balance used for?
An analytical balance is the choice of industry professionals who seek accurate measurements of a variety of types of masses. Analytical balances are built to fine-tune balances and offer minute readability.
How do you use a lab scale?
To properly use a lab balance, there are important steps to ensure are taken:
1. Ensure that objects being weighed are at room temperature to ensure proper measurement. Warm air may cause convection currents that cause the object to measure improperly.
2. Place the object to be weighed on the pan and close the door of the balance to ensure no air contaminates the measurement.
3. Record various measurements after specific time intervals, as objects may change weight once removed from the balance. Air temperature and moisture can affect the measurement of various objects depending on their makeup.
What is the ‘accuracy’ in a weighing balance?
In order to properly measure a sample, it is necessary to ensure a certain accuracy in measurement. Accuracy is measured by taking the degree of closeness of the average value of an object’s displayed weight to the object’s actual weight. This measurement will ensure that your measurements are accurately recorded for various purposes.
How to Select the Right Laboratory Balance or Lab Scale?
Is it time to consider the purchase of a new laboratory balance or lab scale? Before you purchase your next laboratory equipment, ensure that you know exactly what your unique needs are.
Questions To Ask
The first step in selecting the right balance or scale is to take inventory of what activities will be completed with the equipment.
Consider the following questions:
● Will you need precision weighing ability?
● Do your workflows require formulation or check weighing?
● Will your equipment be used in a laboratory setting or in the field to complete measurements?
● What other equipment should your balance or scale connect to in your measuring?
Once you better understand the use for your new scale or balance, you must consider the necessary readability – the amount of division that our scale can display for measuring. It is recommended that in order to measure sizes of 10mg (0.01g) that you purchase a balance or scale with a readability of 0.001.
What capacity do you need for your measurements? Depending on the weight of the containers you will be used to measure samples, different scales and balances will offer varying capacity.
Ensure that the weighing pan of your scale or balance is able to fit the largest items that are being weighed and that the unit is suitable to measure a variety of sizes.
By choosing the best balance or scale, you can ensure that your methods of measurement are efficient and effective for all of your laboratory needs. Take the time to research the available scales and balances to ensure that you purchase a unit that can handle all of your necessary jobs and projects.
