In any laboratory, precision balance is of the utmost importance when conducting scientific experiments. Any imprecise measurements will invalidate the whole experiment and encourage anomalous results. As such, precise weighing scales are an invaluable piece of laboratory equipment, allowing scientists and technicians to weigh out ingredients to the exact specifications they desire. The majority of laboratory scales are digital nowadays, removing any possibility of discrepancies or misreading compared to the usual dial that comes with household weighing scales. Many websites offer a wide variety of precision balance scales for a wide variety of prices. In this article, we look at some of the precision balance scales on offer, from low-end to high-end products that are perfectly suited to the laboratory. |
The cheaper models of scale are battery operated with an emphasis on portability that may be useful in a laboratory environment. Many of these cheaper battery-operated models are designed so that they can be easily stored, often being stackable. However, in a laboratory environment, portability is never going to win over the measurement abilities of the weighing scales and this is where many of these cheaper products fall flat. The value of most weighing scales is in their capacity for weighing (the maximum weight they can calculate) and their resolution (the smallest increment the set of scales can possibly weigh). Customers will find that as the capacity and resolution of the scales increases, their prices rocket into the hundreds. The high-end scales offer more precision balance and are able to calculate variations in weight to up to two decimal points (and at maximum capacity, up to one decimal point), making them incredibly accurate.
The more expensive precision balance equipment will usually require a connection to the mains, rather than a battery-powered cell. These more expensive examples usually come with many more additional features, such as adjustable feet, backlit LCD displays and multiple customisation options and programmable features that provide more control over the functionality of the weighing scales in the laboratory for unique experiments and weighing needs. The maximum capacity for these more expensive scales doubles the maximum capacity of some of the cheapest models on the market, meaning that for the more expensive equipment laboratories will be able to weigh larger amounts far more precisely with a superior scale resolution. For laboratories where precision matters above all else as a way of limiting variables, the pricier scales on the market are a must simply because the cheaper scales will not provide the necessary level of accuracy laboratories require on a daily basis.
