Features and Benefits
Borosilicate 3.3 Metallurgy
Superior optical clarity and mechanical strength with extreme resistance to thermal shock and aggressive chemical reagents.
Airtight Ground-Glass Joint
Precision-ground stopper creates a tight hermetic seal to eliminate sample weight variation caused by ambient moisture gain or loss.
Space-Efficient Tall Form Design
Compact 40×30 mm profile fits easily inside standard laboratory desiccators, analytical balances, and hot-air drying ovens.
Flat Internal Base
Ensures maximum stability on balance pans, preventing accidental tipping during micro-gram sample additions.
Laboratory Applications
- Analytical Gravimetric Analysis: Accurate weighing of solid powders, hygroscopic salts, and secondary reference standards.
- Loss-on-Drying (LOD) Testing: Determining moisture content in pharmaceutical active ingredients (APIs), agricultural grains, and chemical samples.
- Desiccator Storage: Safe, moisture-free storage of pre-dried samples before quantitative titration or spectral analysis.
