There is a wide range of scales and weight measurement equipment available from Sweigh - specialist stockists of instrumentation with a track record of supplying high quality products across numerous industries.
Among the most sophisticated equipment we stock are our analytical balances . Manufactured by leading producer Ohaus, these tools are vital to a range of delicate processes and practices.
In this article, the experts from Sweigh will explain exactly what analytical balances are, their benefits and how to select the best model for your organisation’s needs.
What is an Analytical Balance?
Similar to a scale, a balance is a piece of instrumentation designed to measure the mass of objects and materials. Usually employed in a laboratory setting, an analytical balance is programmed to provide reliable measurements with the highest possible weighing accuracy.
These balances usually offer a readability up to 0.00001 grams, and are commonly used to weigh sub-milligram samples. This is of course why such a level of precision is required.
Balances of this kind are naturally designed with a clear enclosure or draft shield inbuilt, so that changes in pressure, air currents and dust particles are not able to affect the accuracy of their readings.
Temperature must also be managed carefully, as, at such minute levels of measurement, air currents may be formed through natural convection, which may again affect the accuracy of the reading unless the sample is kept at a certain thermal level.
Most analytical balances measure the force required to balance the mass that is being measured, rather than taking a direct reading from the material itself.
The Benefits of Analytical Balances
There are a great many benefits offered by the analytical balances available from Sweigh. See below for just some of the reasons why these sophisticated devices are used to record microscopic measurements in various professional sectors.
Precision and Accuracy
As we have already mentioned, the accuracy with which analytical balances operate is exceptional. Using their specialist features such as draft shields and temperature regulation, these instruments are the epitome of precision when recording sub-milligram weights.
The balances within our range offer maximum weights of 120 - 10200g depending on the model selected.
Display and Readability
Featuring super-clear backlit LCD displays, many of the analytical balances stocked by Sweigh also offer a second-line display that is designed to relay guidance and information.
Many of the balances’ displays feature brightness settings, with data output available by way of RS232, USB and GLP/GMP with real-time clock.
The top of the range Ohaus Explorer Semi-Micro Balance features a 5.7 inch diagonal VGA graphic display with 4-wire resistive touch screen a QWERTY keyboard and a numeric keypad.
Reliability and Ease of Use
Powered by way of an AC adapter and featuring user-selectable environmental filters and communication settings, equipment of this kind can be easily adjusted to suit myriad applications.
Many of the instruments manufactured by Ohaus feature up to 14 operating languages and include stability indicators along with overload/underload indicators, reducing the potential for human error. Many even have fully-automatic internal calibration systems.
For easy cleaning and maintenance, the stainless steel weighing platforms of our analytical balances are removable.
The reliability of analytical balances is such that they are regularly used to streamline lab tasks in busy organisations and institutions and can be trusted for consistent long term use.
Affordability
Considering their highly effective nature, their workflow streamlining benefits and their absolute accuracy, the analytical balances available from Sweigh are comparatively budget-friendly.
With prices ranging from £1,020 to £5,770 - and with a level of reliability that requires minimal maintenance - the time saved and inaccuracies avoided through their use renders them a superb investment for organisations requiring sub-milligram weighing devices.
Investing in an Analytical Balance
The analytical balances available from Sweigh offer numerous specialist features, from four-level user management with password protection to programmable IR-sensors, fully-automatic internal calibration systems and draft shields with automatic doors.
The instrument you choose should be selected based on your organisation’s particular requirements, your budget and the environment in which the balance is to be used.
It is important to note that precision balances of this kind should be regularly maintained and calibrated, as, if their performance is compromised in any way, significant inaccuracies may well result.
Sweigh also stocks numerous other kinds of scales and balances for a range of specialist purposes across industries, including bench scale, counting scales, jewellery scales, moisture analysers, platform scales and shipping scales.
