Product Description
I. Overview
Weighing paper is the most essential weighing auxiliary consumable in the laboratory. Manufactured from virgin wood pulp or cotton pulp through kraft pulping and supercalendering, producing double-sided smooth parchment paper with uniform texture. The paper has a uniform milky white color, fine and smooth surface, odorless, lint-free, and free of optical brighteners.
Specifically designed for analytical balance weighing, effectively preventing powders and solids from directly contacting the balance pan, protecting precision equipment while ensuring accurate weighing results. The low hygroscopicity and chemical inertness of weighing paper make it suitable for most routine laboratory weighing operations.
🔬 Core Value of Weighing Paper:
Protect the Balance: Prevents direct sample contact with the pan, avoiding corrosion, contamination, and wear.
Ensure Accuracy: Lint-free and non-hygroscopic, does not affect weighing precision.
Improve Efficiency: Sample can be transferred together with the paper, no secondary transfer required.
Easy Cleaning: Single-use, discard after use, avoids cross-contamination.

III. Material & Workmanship
Manufactured from imported virgin wood pulp or high-quality cotton pulp through kraft cooking to remove lignin, followed by bleaching, washing, beating, papermaking, and supercalendering. Supercalendering provides double-sided smooth surface properties, reducing powder adhesion and static attraction.
All products are cut and packaged in cleanroom environments to prevent secondary contamination. Each batch undergoes lint testing and static testing for quality assurance.
