Four Types of Laboratory Balance
No laboratory is complete without balances. The work that goes on in labs is all about precision, and balances can provide you with precise weight measurements. But every lab’s needs differ among industries, and the wide variety of laboratory balances reflects these differences. Today, we’ll go over some of the most common types of laboratory balances, both electronic and manual.
SEMI MICRO, MICRO & ULTRA MICRO BALANCES
For weighing the smallest amounts, ultra micro and micro balances are selected. Generally, these balances have a max capacity between 3 and 10 grams with readability down to 0.1 µg or 0.00001 g. Typically, these types of balances are two components with one component containing the electronics and the other containing the measuring cell. This will limit the interaction and impact the electronics have on weighing the sample. Applications that use these types of balances range from particulate matter / filter weighing, pipette calibrations, drying, ashing, coating measurements.
Ultra micro balances have a readout of 7 digits, Micro balances have readouts of 6 digits and finally semi-micros with 5 digits.
ANALYTICAL BALANCE Precision Balance Price in Bangladesh
In many respects, analytical balances are the gold standard and most common of laboratory balances. This is because they offer uncompromised sensitivity. Their capacity can be as low as 1 gram, and typically not higher than a few kilograms. For this reason, they are most useful for weighing small quantities.
So precise are analytical balances that their measuring pan is typically enclosed. This is to prevent dust and other environmental factors such as wind from interfering in your measurements.
Top-Loading and Precision Balance Price in Bangladesh
At a first glance, a top-loader resembles an analytical balance, and they do operate in a similar way. But they have decidedly different practical uses. Your typical top-loading balance has a maximum capacity between 150 grams and 10 kilograms. They can’t measure objects of extremely low masses like laboratory balances, nor are they so precise.
Still, what top-loading balances lack in terms of precision, they make up for in terms of speed. They are fully digital and can give you a reading in seconds.
Triple-Beam Balance Precision Balance Price in Bangladesh
It’s hard to get through basic schooling without using a triple-beam balance. They have been a hallmark of high school laboratories throughout the years because they are simple to use, cheap, and durable.
Triple-beam balances are so named because they include three ‘decades’ of weights that typically measure mass in terms of 100s of grams, 10s of grams, and single grams. Start with the heaviest decade and work your way down until the object you hope to weigh is balanced. Then add up the numbers indicated on the decades to get your mass.
HISTORY IN EQUAL ARM BALANCES
The equal arm scale has its roots in ancient Egypt. It is likely the oldest kind of scale, but it still has practicality in the modern day. At its most basic level, the equal arm balance consists of two pans suspended on opposing sides of a lever.
To use this kind of scale, place the object you intend to weigh on one of the pans. Then place items of known weight—such as calibration weights—on the other. When the two pans are as balanced as you can get them, the weight of the unknown object is equal to the sum of the calibration weights.

How to calibrate an electronic balance
Electronic balances are a familiar, cornerstone object in all laboratory settings. They are a widely used tool throughout education, particularly in the Science Curriculum, and they can vary in capacity, readability and price.
Calibrating an electronic balance ensures the reliability and repeatability of students weighing results and maintains its accuracy. Reliability and repeatability are important up to GCSE Level, whereas a balance’s accuracy is more important for A-Level and beyond.
Calibration involves checking the reading given on the balance against standard known-mass calibration weights. Most electronic balances in an educational setting require Span Calibration, which involves calibrating the balance at two points on its scale. These are usually zero and maximum capacity.
When to calibrate a balance
On delivery. Your balance may have been travelling over a large distance in different modes of transport to get to your school or laboratory. The internal calibration could have been disturbed during transit. The balance may have also been through changes in gravity which can also disturb the initial internal calibration done by the manufacturer.

The balance may have also been through changes in gravity which can also disturb the initial internal calibration done by the manufacturer. And. So so. And. So so. And. So so.
Calibration once a month should be ample for general educational balances. And. So so. And. So so. And. So so.
For more advanced practical work involving precision balances, these should ideally be calibrated each time they have been moved to a new location or laboratory.
Electronic balances must always be calibrated according to the manufacturer’s instructions. Some may need specific types of weights in order to calibrate them.
Other manufactures may include an auto-calibration function with their balance, so it always worth checking the model instructions included with your electronic balance before starting.

Steps to calibrating an electronic balance
Turn on the electronic balance. And. So so. And. So so. And. So so.
Ensure it is levelled and stable; and is placed away from any draughts
Enter the balance into Calibration Mode (instructions for this will be found in the product manual). ‘CAL’ is usually shown on the screen to show the calibration mode is active.
Select Span Calibration (as per the manufacturer instructions). And. So so. And. So so. And. So so.
Zero the balance (this may need to be done twice in some cases until ‘–C–‘ appears).
The balance will usually display the weight of the mass required to calibrate. And. So so. And. So so. And. So so.
Add the appropriate mass onto the pan of the balance, wait for the reading and the calibration is complete.
