Rubber Corks, Assorted Manufacturer,Supplier and Exporter in India
Product Code : SCL-ELE-11918
This assorted fleet of
natural rubber stoppers is engineered for the hermetic sealing of heterogeneous
glassware apertures in Secondary and Vocational science curricula. Composed of
high-density vulcanized rubber, these units ensure compliance with ASTM D2000
standards for elastomeric recovery and chemical resistance. Optimized for
high-enrollment laboratories requiring a broad range of calibrated diameters
for pressurized and vacuum-tight experimentation.

Key Pedagogical Outcomes
·
Assorted
Dimensional Gradient: Allows students to
determine optimal friction-fit seal pressure for varying vessel neck diameters,
supporting "Experimental Apparatus Assembly" modules.
·
High-Visibility
Red/Orange Pigmentation:
Facilitates rapid inventory audits and safe identification of sealed hazardous
reagents, supporting "Laboratory Safety and Inventory Management"
protocols.
·
High-Rebound
Elastomeric Memory: Provides repeatable
vacuum-tight sealing during gas evolution experiments, reinforcing accuracy in
"Quantitative Chemical Synthesis" curricula.
International Logistics & Compliance
To ensure material
integrity and prevent oxidative perishing during transcontinental maritime
transit, all stopper packs are secured in UV-shielded moisture-barrier primary
packaging and housed in export-grade seaworthy crating (ISPM-15 compliant).
International procurement documentation includes the Manufacturer’s
Authorization Form (MAF), Batch-specific Certificate of Conformance (CoC), and
Material Safety Data Sheets (MSDS). This fleet is fully tropicalized; the
rubber compound is batch-tested for ozone resistance and thermal stability in
environments reaching 45°C and 90% Humidity to prevent material hardening or
surface tackiness in extreme climates.
