Glass Stoppers from Rama Scientific Glass industries are precision-engineered laboratory components made from borosilicate glass 3.3, offering resistance to thermal shock and chemical corrosion. Each stopper is ground to fit standard taper joints such as 14/23, 19/26, and 24/29, ensuring a leak-proof seal for reagent bottles, flasks, and distillation setups. The variants include solid, hollow, and flat head designs, each serving distinct needs in handling, weight reduction, or durability.
The solid stoppers provide maximum sealing strength for long-term storage, while hollow stoppers reduce weight and thermal transfer, ideal for applications requiring frequent temperature changes. Flat head stoppers improve grip and ease of use in high-frequency environments. Borosilicate glass 3.3 is a standard material for laboratory glassware, known for its low thermal expansion and high resistance to chemical attack, making it suitable for a broad selection of laboratory conditions.
These stoppers are used in chemical, pharmaceutical, and educational laboratories where secure containment of reagents is critical. Buyers typically source them in bulk for laboratory setups, with compatibility across standard labware brands. The stoppers are compliant with ISO, CE, and FDA standards, which are typical certifications for laboratory glassware used in regulated environments.

Before ordering, verify the taper joint sizes of your existing laboratory glassware to ensure compatibility with the stoppers’ specified dimensions (14/23, 19/26, 24/29). Confirm the material requirements for your applications, as borosilicate glass 3.3 is suitable for most laboratory conditions but may not be ideal for highly specialized environments. Request samples to test the fit and sealing performance under your specific conditions.
Discuss logistics with Rama Scientific Glass industries, including lead times, shipping methods, and Incoterms such as FOB or CIF. Clarify packaging options to ensure the stoppers arrive intact, as laboratory glassware is fragile and requires protective packaging. Payment terms should also be confirmed, with common options including TT or LC, depending on the buyer’s preferences and the supplier’s policies.
Inspect the stoppers upon arrival for dimensional accuracy, material quality, and absence of defects such as cracks or chips. Request certificates of compliance for ISO, CE, and FDA standards to ensure the products meet regulatory requirements. For critical applications, consider third-party testing to verify the stoppers’ performance under thermal and chemical stress.
