Core Technological Strengths:
1. High-Precision Constant Weight Analysis (Core Product Line) LabStone excels in constant weight testing technology, particularly for total migration and non-volatile matter determination. Our high-precision constant weight analyzers, ignition residue & ash content testers, and atmospheric/vacuum drying constant weight instruments deliver excellent stability and accuracy. These instruments are widely used for:
- Migration testing of food contact materials and pharmaceutical packaging
- Ash determination of drugs
- Drying weight loss, loss on ignition, and moisture content analysis
Patented balance protection technology ensures measurement error remains less than 0.3 mg even under high-temperature and high-humidity conditions.
2. Barrier Property Testing We provide industry-leading barrier performance testing solutions, including:
- Water Vapor Transmission Rate Tester (WVTR)
- Oxygen Transmission Rate Tester (OTR)
- Gas Transmission Rate Tester (GTR)
Equipped with advanced dynamic leak detection technology, our systems achieve high accuracy (as low as 0.005 units), making them ideal for evaluating high-barrier materials used in pharmaceutical and food packaging.
3. Comprehensive Packaging Testing Equipment LabStone offers a full range of packaging physical property testing instruments, including:
- Tensile Strength Testers
- Heat Seal Testers & Seal Strength Testers
- Friction Coefficient Testers
- Falling Dart Impact Testers
- Impact Testers and other related equipment
These instruments comprehensively support mechanical property, sealing performance, friction, and impact resistance testing for plastic films, composite films, paper packaging, and various packaging materials.
Trusted by manufacturing enterprises, third-party testing institutions, universities and research institutes, LabStone has been certified as a National High-Tech Enterprise. In the 2018 National Innovation and Entrepreneurship Competition, the company ranked 7th in the Guangzhou Division and 18th in the Guangdong Provincial Division.
Adhering to the philosophy “Precision comes from rigorous processes; sincerity lies in every detail”, LabStone is committed to technological innovation and will continue to provide more reliable and professional testing solutions to support quality control and industry standardization across various sectors.
