Cork stopper, for Lab Use Manufacturer,Supplier and Exporter in India
Product Code : SCL-ELE-11901
These tapered natural
cork stoppers are engineered for chemically inert sealing of laboratory flasks
and tubes in University and Secondary education environments. Compliant with
ASTM standards for dimensional uniformity, they provide a biodegradable
alternative for non-corrosive chemical storage and biological specimen
preservation. Available in standardized sizes from No. 0000 to No. 24 to ensure
hermetic fitment across diverse laboratory glassware.

Key Pedagogical Outcomes
·
High-Compressibility
Natural Fiber: Allows students to
achieve airtight seals in titration and gas evolution assemblies without
applying excessive mechanical stress to Borosilicate 3.3 glass necks.
·
Tapered
Design Geometry: Facilitates universal
fitment across irregular glassware apertures, supporting student-led
experimental design in "Properties of Matter" and "Organic
Synthesis" modules.
·
Porous
Thermal Insulation: Provides safe
handling points for heated vessels, reinforcing laboratory safety protocols
during "Thermodynamics and Heat Transfer" curricula.
International Logistics & Compliance
To ensure material
integrity and prevent fungal degradation during transcontinental maritime
transit, all stoppers are treated with anti-microbial agents and secured in
moisture-barrier primary packaging within export-grade seaworthy crating
(ISPM-15 compliant). International procurement documentation includes the
Manufacturer’s Authorization Form (MAF), Certificate of Phytosanitary
Compliance (where applicable), and Batch-specific Certificate of Conformance
(CoC). The product is tropicalized and batch-tested for dimensional stability
in environments reaching 45°C and 90% Humidity, ensuring the wood does not
shrink or perish in extreme climates.
