Polaris PPB 623i: a precision laboratory balance with a lit weighing chamber and large display
Model number: PPB 623i | Adam item number (MPN): 1010017681 | Also written as PPB623i or PPB-623i
A precision balance is a laboratory scale for everyday weighing where accuracy matters but analytical-balance sensitivity is not needed. The Adam Polaris PPB 623i weighs up to 620 g and reads to 0.001 g (1 mg), making it suited to sample preparation, formulation and routine weighing in the lab.
The weighing chamber has built-in LED lighting so powders and liquids are easy to see, even in dimly lit spaces such as fume hoods. A large 7.4-inch display shows instructions, results and application status at a glance, and a colour-changing backlight confirms whether a sample is within set weight limits.
Key features
- Precise results: 620 g capacity with 0.001 g (1 mg) readability.
- LED-lit weighing chamber: Clear visibility of samples, with a removable draft shield for easy cleaning.
- Colour-changing backlight for checkweighing: Red if the sample is too heavy, yellow if too light, and green if it is on target.
- Built-in connectivity: Bluetooth®, RJ45 Ethernet, USB and RS-232 interfaces connect the balance to computers, printers and LIMS software to help reduce transcription errors.
- Data and traceability: Stores up to 200,000 weighing results and up to 200 ingredients (10 formulations of 20 ingredients each), with GLP-compliant data output and support for GMP record-keeping.
- Multiple weighing modes: Weighing, parts counting, percentage weighing, checkweighing, check counting, accumulation, net total, dynamic/animal weighing, density determination, formulation and display hold.
- Security options: Multi-level permissions (1 administrator and up to 99 operators) and a security slot for an optional lock and cable.
- Durable, easy-clean design: ABS plastic housing and a grade 304 stainless steel weighing pan.
- Stable readings: Selectable digital filtering helps reduce the effects of vibration and disturbances.
- Calibration: Internal automatic calibration, with external calibration also available.
- 5-year manufacturer's warranty.
Ideal for
- General laboratory weighing and sample preparation
- Recipe and formulation work with stored ingredients
- Checkweighing samples against set limits
- Parts counting and percentage weighing
- Labs that need connected, traceable weighing records
Choosing the right Polaris model
Polaris PPB precision balances come in several capacities. Models ending in "e" use external calibration (a separate calibration weight is needed), while models ending in "i" have internal automatic calibration. Check the model letter carefully when ordering.
