Borosilicate 3.3 offers extreme chemical resistance, minimal thermal expansion, and unmatched purity, preventing leaching in sensitive HPLC and active pharmaceutical synthesis.
The Science of Quality Laboratory Manufacturing
In analytical chemistry and pharmaceutical testing, volumetric accuracy and chemical inertness are non-negotiable parameters. Minor imperfections or leaching from lower grade soda-lime glass can distort spectral baselines, catalyze unwanted degradation, or invalidate months of clinical trials.
Thermal and Hydrolytic Resistance
Borosilicate 3.3 glass features a high proportion of silica (approx. 81%) and boric oxide (approx. 13%), yielding an extremely low linear coefficient of thermal expansion of approximately 3.3 × 10⁻⁶ K⁻¹. This allows it to withstand extreme temperature differentials and direct flame heating without cracking.
“Every piece of laboratory glassware manufactured at Nikam Scientific is stress-relieved in automated annealing lehrs to eliminate residual thermal stress.”
Maintenance and Preserving Calibration
To maintain Class A certification across decades of use, volumetric instruments must never be subjected to temperatures exceeding 250°C during cleaning, nor exposed to concentrated hydrofluoric acid or hot concentrated phosphoric acid.
