- Autoclavable at 121°C
- ASTM E-960
OVERVIEW:
GWSI Beaker ASTM Low Form 10 ml provides a compact stable vessel for precise mixing and heating of the smallest liquid volumes. Crafted from premium borosilicate 3.3 glass, it delivers high thermal shock resistance and complete chemical inertness. The low-profile design offers excellent balance even on miniature hotplates. Clear graduations enable quick readings in micro-scale experiments.
HISTORY:
Chemists in the 1800s required tiny vessels that could withstand heating without cracking or tipping. beaker invented by John Joseph Griffin solved stability issues of narrow designs. Later, borosilicate 3.3 glass made these ultra-small beakers safe for repeated thermal cycles in early analytical work.
APPLICATIONS:
– Pharmaceutical labs for micro-preparation and titration
– Biotech research facilities with tiny sample volumes
– Industrial chemical testing and quality control
– School and educational institute teaching experiments
– Colleges and university chemistry labs
– Research labs and analytical institutes
MANUFACTURING PROCESS:
GWSI melts high-purity borosilicate 3.3 glass and shapes the ASTM beaker via automated molding. Precision forming creates uniform walls, spouts, and bases, followed by annealing to relieve thermal stress.
TESTING PROCESS:
Quality begins with manual inspection followed by polarization stress test to ensure zero residual stress. High-precision verification follows I.S.O. and DIN standards using manual or automatic testing machines.
PRINTING PROCESS:
These are baked in high-temperature kilns for permanent ceramic glass fusing so the details never fade.
PACKAGING PROCESS:
Final cosmetic sorting removes any blemishes. Each beaker goes into heavy-duty double-wall boxes with shock-absorbing bubble wrap for safe export.
MAINTENANCE & SAFETY:
– Rinse immediately after use with mild detergent or suitable lab cleaner
– Autoclave safely at standard conditions
– Store on padded shelves to protect the base and rim
– Inspect graduations and walls regularly for chips or cracks
– Heat and cool gradually to avoid thermal shock
