Analytical balance scales – Buying guide & Comparison
If you’re short on time and you just want to find the best analytical balance scale, this short paragraph should help you get exactly the model you need. According to our findings/research, the U.S. Solid USS-DBS8 is the best analytical balance scale because it is a fully electronic device that ,measures weights ranging up to 200 grams, with 0.1 mg precision. You can easily read the measured weight using the convenient blue backlit LCD screen, for trouble-free viewing. Measuring units can be either carats or ounces to accommodate laboratory specifications. The cutting edge RS-232 interface allows linking with your computer to enable serial data exchange between the balance scale and your PC. The reliable draft shield effectively prevents inaccurate weighing when working with small quantities that can be affected by the slightest nuances in humidity or the breeze. If the U.S. Solid USS-DBS8 is unavailable, your second option should be the U.S. Solid USS-DBS3-3.
Our Top Choice
This measuring scale is a nifty product which can detect a quantity that's in the sub-milligram range, meaning it is ideal for those who need precision in all types of fields. It can be used to measure the weight of any substance, and it will also allow you to convert the units into any system.
One reviewer pointed out that the device can’t weigh items that exceed 200 grams and that it doesn't feature a calibration certificate.
If you want something precise and easy to use, then this should be on your options list. You can use it in any environment without worrying about interference, and the LCD screen will be a lifesaver.
One selling point of this analytical scale is its compact body, which will allow you to move it from one room to another with ease. It is lightweight, at only four pounds. The maximum capacity is 300 grams, and it runs on a dual power supply, AC or DC, which offers a lot of versatility.
As a complaint, this machine doesn't work well with recurrent calibration, as it will start to lose its accuracy by 0.2 grams in a few years.
When it comes to drawing the conclusions, we realize this model has something to offer to any user. It is high-quality and well made, and more important, portable and accurate to the extreme.
Give a try to the main features of this item. It weighs in both grams and ounces, which is ideal especially for pharmacists and people who work in the chemical industry. It rocks an LCD screen and converting the scaling systems will be a breeze with the built-in features.
As one buyer pointed out, the machine is fantastic, but it can be limiting for those who want to weigh things that exceed the 1000-gram limit.
The bottom line is that this scale is complete from all points of view. It has many positive parts, like accuracy and the LCD screen, which will make repeated and subtle measurements much more enjoyable.
Able to read extremely small quantities between 0.01 mg (0.00001 g) and 1 mg (0.001 g), an analytical balance proves to be indispensable in the laboratory setting for interval weighing when connected to a PC with special software, differential weighing, density measurement, formulation weighing, pipette calibration, sample management as well as other analytical weighing applications. These are what separate the products featured in the best analytical balance scale reviews from the less stellar ones.
Capacity and calibration that suit the needs of your lab
The capacity of the analytical balance scale is a primary aspect to consider here. The first thing you want to know when looking into this element is how much would you actually need the instrument to weigh up to. It is pointless, for instance, to get a balance that weighs up to 300 grams if the items you measure are only up to 100 grams each. The capacity of the instrument should be high enough to handle what you want it to, with perhaps a tiny extra just in case, but do not go overboard to actually push the price spectrum higher than needed.
Some manufacturers offer different weighing capacity ranges, such as 1 to 250 grams and 250 to 500 grams for effortless selection. For small analytical measurements, the 1 to 250-gram weighing capacity range should be enough. You may also opt for either manual or automatic internal calibration. On the larger end of the weighing spectrum, go for analytical balances with a weighing capacity range of 250 to 500 grams or even up to 1000 grams, also with either automatic internal or manual calibration.
With automatic internal calibration, you enjoy convenience and time savings because of the easy readability and capacity, but cost may be a big issue. A lot of automatic internal calibration models also feature external calibration. Manual calibration, typical in a vintage analytical balance scale, involves the traditional placement of a certified calibration weight on the instrument and then manually entering the calibration mode of the device. The only issue with this type of calibration is the need to get the external weight recertified periodically to ensure correct calibration of the balance at all times.
Accuracy and suitable division size or resolution
When checking out the accuracy of an analytical balance, manufacturers often specify a combined maximum error of two divisions. Thus, when weighing out 100 grams of fine powder with an accuracy requirement of +/- 1 mg, using a balance with an increment size of 0.01g/10mg will not provide reliable sample weighing because you won’t be able to tell if the sample is short or in excess by 1 mg. That being said, a division size of 1 mg may give you a suitable reading but when the accuracy or maximum error of a balance is taken into account, you will still need a device with 0.1 mg readability or resolution. The cardinal rule is to get an analytical balance with as small an increment size as possible to ensure you are closer to the desired measurement. Naturally, the smaller the increment size, the costlier the instrument. The maximum difference between the displayed weight and the test weight determines the accuracy of the device.
The increment size, also known as the readability, division size or resolution, refers to the smallest unit the balance will display, so a 0.1 mg increment size will mean the display on the scale will increment by 0.1 mg. Do not mistake the increment size for accuracy. Get information on accuracy from the instrument datasheet.
Functionality and features to suit lab needs
An analytical balance with dynamic weighing is suitable for use with small animals. With internal calibration, you would simply need to press a button to calibrate the test weights instead of manually calibrating them. You will also have to decide on the units you will use for weighing, whether in ounces or grams, milligrams, troy ounces or grains, etc. An analytical balance with parts counting function allows you to keep track of the number of very small items you weigh to determine if the set of items or the single item is as specified. Some models come with statistical function. High-end models come with a number of application modes, adjustable angle displays, vibration filtering, user-programmable touchless sensors, well-designed graphical user interface, and true-type printing, making them extremely easy to use.
A draft shield prevents inaccuracies caused by small things such as vibrations, the room temperature, humidity and the breeze. An anti-vibration work surface may be needed for use with the instrument. A de-ionizer feature eliminates the static charge or any electrostatic issues when weighing plastic elements and other conductive items. The ability to interface with data logging software is useful for storing data on a computer. Some models are equipped with density determination kits, in-use covers for protecting the display, and traceable calibration certificates for quality measuring procedures.
