Specific Gravity Bottles, Borosilicate Glass Manufacturer,Supplier and Exporter in India
Product Code : SCL-M-11515
The Specific Gravity Bottles are precision-engineered
laboratory vessels designed for the empirical determination of liquid density
and relative density (specific gravity). Fabricated from
thermal-shock-resistant Borosilicate 3.3 glass,
these uncalibrated units are optimized for University and Vocational
chemistry curricula. They facilitate high-accuracy weighing methods in
compliance with ASTM E438 Type I, Class A glass
standards for rigorous laboratory environments.

Key Pedagogical Outcomes
·
Precision-Ground PTFE Capillary Stopper: Allows students to "Apply" the
principle of constant volume displacement, facilitating the calculation of
liquid density to four decimal places.
·
High-Integrity Borosilicate 3.3 Construction: Enables students to "Evaluate" the
specific gravity of volatile or mildly corrosive reagents without material
degradation, reinforcing advanced stoichiometry modules.
·
Uncalibrated Design:
Requires students to
"Construct" their own calibration curves using distilled water,
supporting "Level 4: Analysis" of experimental error and meniscus
reading.
International Logistics & Compliance
This School Instrument is prepared for global institutional
distribution using export-grade seaworthy crating (ISPM-15
compliant) with internal shock-absorption layering to prevent glass
breakage. Comprehensive documentation is provided for international procurement
officers, including the Manufacturer’s Authorization
Form (MAF), Certificate of Conformance (CoC), and Material Safety
Data Sheets (MSDS). The tropicalized packaging
is engineered for trans-shipment through high-humidity zones, preventing
moisture-induced etching of the glass surfaces during storage in environments
up to 45°C/90% Humidity.
