What is top loading balance?
A ‘top-loading balance’, as they are often referred to as, is a balance that does not have a draft shield. Samples are loaded directly onto the weighing pan. These balances typically have a readability of 1 mg or less. This readability range puts them into a class of precision balances.
How do you take care of a top loading balance?
Thankfully, there are certain steps you can take to help make sure your machine has a long life and that your balance readings are accurate:
- Position your unit correctly.
- Let it warm up.
- Don’t overload the balance.
- Clean the unit regularly.
- Calibrate it often.
Why is a top loading balance better than an analytical balance?
Top-loading balances, which can measure objects up to 200 g, are less expensive but less exacting than analytical balances. They are considered semi-analytical balances, with a readability of up to three decimal places to the right of the decimal point (up to . 001 g). Precision balances have a readability of 0.01 g.
What is the difference between analytical balance and top-loading balance?
An analytical balance will measure the accuracy of 0.0001 to 0.00001g. If extream accuracy is not important a top-loading balance will work just fine in measuring the accuracy of 0.001g. There are many other types of balances available on the market not covered in today’s article.
Why you should never weigh a hot object?
3) Do not weigh hot or cold objects on the balance. Hot objects will give erroneously lower readings due to air buoyancy, while cold objects will give higher readings due to the condensation of water vapor.
Which is more accurate top-loading balance vs analytical balance?
Conclusion, for extream accuracy an analytical balance is a better choice for your laboratory. An analytical balance will measure the accuracy of 0.0001 to 0.00001g. If extream accuracy is not important a top-loading balance will work just fine in measuring the accuracy of 0.001g.
Why would you choose a top loading balance over an analytical?
