In laboratory environments, accuracy, consistency and safe construction are vital. Digital Laboratory Scales are designed to withstand dangerous or unstable chemicals, reliably maintain control over variables such as temperature or air movement, and many can send information directly to a recording device.

These scales must be well designed, simply because their ability to mitigate variables are vital to laboratory experiments. Digital readouts are also very important in laboratory experiments, where precise numerical values are often required, and are rarely provided on analogue readouts. Look for scales with reduced numbers of parts, or etched metal surfaces in order to control air flow and temperature when precision weighing conditions are not ideal.

Choosing the right digital laboratory scales for your business can rest on several factors, the most important being the level of accuracy you require. Also ensure that the scale has any required features, such as USB or wireless connections to computers, or interchangeable measurement in both standard and metric units of weight.

Pay attention to the quality ...

Digital laboratory scales usually have fine stainless steel construction, with little room for dust build up, as dust or debris can create small anomalies in laboratory results. For high precision work, look for an accuracy of at least 0.001g, and protective shields to prevent air currents from affecting the scale reading. Automatic tare functions may also be a requirement when doing liquid measurements.

Lab scales are often required to count items of similar weight, provide statistical data through computer link ups, and perform mathematical calculations (such as percentages). The diverse functionality of these types of scales make them useful for a variety of applications within the medical, or educational field.

Of course, the wide range of available scales means that they are available at varying prices, depending on construction and available features. Generally, features like Bluetooth technology, automatic readouts, and automatic calibration are reflected in the price, but for a clinical environment, these features may be necessary.

To ensure the reliability required in laboratory environments, laboratory scales are generally electrically powered. They will also often combine the electric power with a battery backup to preserve data and settings in the event of power failure. Some lab scales will also come standard with an external, or even internal calibration mass, which can be used in the event of electrical calibration errors.

Lab scales may be used by a variety of professionals, including medical research teams, university departments, pharmaceutical researchers, and in the food technology field. Each industry should ensure that any scale is industry appropriate, as some digital scales, or pocket scales may not meet accuracy and safety requirements in a laboratory environment.
