Analytical Balance & Density Kit

High-precision analytical balance with integrated density determination kit. Offers 220 g maximum capacity with 0.1 mg reading accuracy and built-in automatic calibration. Compliant with OIML Class I standards and GLP requirements for demanding laboratory applications.

Precise weighing and density determination

Almost every plastics test depends on an accurate mass — MFI cut-offs, ash and carbon black residues, OIT samples — and density is the fastest way to identify a polymer or detect fillers and mixed material. This analytical balance weighs up to 220 g with 0.1 mg readability, 0.07 mg repeatability and internal automatic calibration to OIML Class I, and the included density kit measures density by immersion (ISO 1183, ASTM D792). RS232, USB and optional Wi-Fi connectivity support GLP record keeping.

Frequently Asked Questions

How is density measured with the kit?

The sample is weighed in air and then immersed in a liquid of known density; from the two weights the balance calculates density according to Archimedes' principle (ISO 1183-1, ASTM D792).

What are the balance specifications?

220 g capacity, 0.1 mg readability, 0.07 mg repeatability, ±0.2 mg linearity and a 2-second stabilisation time.

Does it need external calibration weights?

No — it has internal, automatic calibration; it meets OIML Class I accuracy and GLP requirements.

Why is density important for plastics?

Density identifies polymer type and grade (for example HDPE vs LDPE) and reveals fillers or contamination in recycled material.
