The Adam Equipment Polaris PAB 125i is a dual-range semi-micro analytical balance with internal calibration. It weighs up to 80 g with 0.00001 g (0.01 mg) readability, and up to 120 g with 0.0001 g (0.1 mg) readability. You get semi-micro resolution for very small samples and standard analytical resolution for heavier containers, on the same balance.
It is designed for laboratories where small sample masses drive results: pharmaceutical and chemical QA/QC, research laboratories, universities and colleges, and environmental and wastewater labs doing gravimetric analysis. A large colour display, a lit weighing chamber, and Ethernet, Bluetooth®, RS-232 and USB connections help with recordkeeping and data transfer. The PAB 125i is available in Canada from Cambridge Environmental Products with CAD pricing and Canadian purchasing support.
Up to 80 g, the balance reads to 0.01 mg for semi-micro work such as weighing reference standards or very small samples. Between 80 g and 120 g it reads to 0.1 mg, so you can still tare heavier vessels or weigh larger samples at standard analytical resolution. One balance covers jobs that would otherwise need two.
The built-in calibration mass lets the balance adjust itself without you handling external weights. This helps keep results consistent as room conditions change, which matters at 0.01 mg readability. External calibration is also available for verification with your own certified weights.
On the PAB 125i, an air diversion channel below the pan carries warm air away from the weighing chamber. Warm air rising inside a draft shield is a common cause of drifting readings at semi-micro resolution, so this helps readings settle and stay stable.
An LED-lit weighing chamber makes small samples and powders easier to see. The 7.4" multi-colour backlit display shows guidance and results clearly. In checkweighing mode the backlight changes colour to show whether a sample is under, within or over your limits.
RJ45 Ethernet, Bluetooth, RS-232 and two USB ports let you send results to a PC, printer or LIMS instead of writing them down. This reduces transcription errors and supports GLP and GMP recordkeeping.
Multi-level security supports one administrator and up to 99 operators, so you can control who changes settings. The internal memory stores up to 200 ingredients (10 formulations of 20 ingredients) for repeatable recipe work.
Adam Equipment backs the PAB 125i with a 5-year warranty.

Cambridge Environmental Products is a Canadian-owned laboratory equipment distributor based in Ontario and has served Canadian laboratories since 1993. We supply Adam Equipment analytical balances with CAD pricing and shipping across Canada. We help pharmaceutical and chemical QA/QC labs, research laboratories, universities and colleges, and environmental and wastewater labs choose the right balance. Browse our full range of balances and weighing scales.
A semi-micro balance reads to 0.01 mg (0.00001 g), ten times finer than a standard analytical balance at 0.1 mg. The PAB 125i reads to 0.01 mg up to 80 g, and to 0.1 mg from 80 g to 120 g.
Loads up to 80 g are displayed in 0.01 mg steps. Above 80 g, up to the 120 g maximum, the balance displays in 0.1 mg steps.
Yes. The "i" model has internal automatic calibration, and external calibration with certified weights is also available.
Adam lists a USP minimum weight of 0.03950 g (k=2, U=0.10%) and an optimised USP minimum weight of 0.00820 g. Your actual minimum weight depends on your environment and should be confirmed during installation and qualification.
Yes. It has RJ45 Ethernet, Bluetooth, RS-232 and two USB ports for sending results to PCs, printers and LIMS.
Yes. Adam describes the Polaris as supporting GLP and GMP practices, with user permissions, data output and published USP minimum-weight figures.
It is well suited to gravimetric work such as filter weighing, where 0.1 mg or finer readability is typically used. Check your method's balance requirements.
Yes. Cambridge Environmental Products supplies the PAB 125i in Canada with CAD pricing, Canadian shipping and purchasing support.
