Reagent Bottle with Screw Neck

DescriptionSuperior Chemical Integrity & Optical ClarityOsmosis Scientific Reagent Bottles are engineered for the high-integrity storage of aggressive reagents, volatile solvents, and sensitive biological media. Unlike standard soda-lime glass, our Type I Borosilicate 3.3 construction ensures a low linear expansion coefficient (3.3 × 10⁻⁶ K⁻¹), providing unmatched resistance to thermal shock and chemical leaching. This inert surface prevents pH shifts, ensuring your solutions remain stable during long-term storage.Ergonomic Safety & GL 45 StandardizationWe prioritize laboratory safety through functional design. Every bottle is equipped with:GL 45 Polypropylene Cap: A standardized, leak-proof screw neck compatible with most laboratory dispensing systems.Drip-Free Pouring Ring: Prevents hazardous chemical run-off, protecting the user and preventing benchtop contamination.Sloping Shoulder Design: Optimized for a smooth, consistent liquid flow during high-precision pouring.Permanent Graduations: High-contrast white enamel markings for easy volume assessment and a large marking spot for reliable sample identification.Technical Specifications & ComplianceTo ensure traceability and performance in regulated QC/QA environments, our glassware adheres to international metrology standards:Material: Borosilicate 3.3 (High-purity glass)Compliance: Fully compliant with ISO 4796-1 and IS 1388.Thermal Limits: Heat resistant up to 500°C; Autoclavable at 121°C.Range: Available from 25ml to 20,000ml (including Amber glass variants for UV-sensitive media).Applications Across IndustriesPharmaceutical R&D: Ideal for preparing standard solutions and buffer storage.Media Preparation: Built to withstand repeated autoclave sterilization cycles without clouding or “frosting.”Industrial Testing: Resistant to organic solvents, strong acids, and alkalis.Material Science Comparison: Borosilicate 3.3 (Type I) vs. Soda-Lime (Type III)Technical PropertyOsmosis Borosilicate 3.3Standard Soda-LimeSafety & Performance ImpactLinear Expansion3.3 × 10-6 K-19.0 × 10-6 K-12.7x lower expansion prevents mechanical stress and cracking during heating.Thermal Shock ResistanceResistant to ΔT of 160°CRisk of failure at ΔT of 40°CCrucial for safe autoclaving and rapid temperature changes in the lab.Max Working TempUp to 500°C (Long-term)Max 150°C to 200°CEssential for high-temperature synthesis and direct flame applications.Chemical DurabilityHigh (Hydrolytic Class 1)Low (Hydrolytic Class 3)Prevents ion leaching (alkali release) which can alter solution pH.Recommended UseTitration, Heating, StorageGeneral Storage, Ambient UseEnsures compliance with ISO/ASTM standards for professional research.Reagent Bottle with Screw Neck – Borosilicate 3.3 Storage Bottles with GL ThreadCapacity (mL)Dia (mm)Height (mm)Pack ofSKUEnquiry10*365010RBSN-0010Enquire Now25*367010RBSN-0025Enquire Now50*468710RBSN-0050Enquire Now1005610010RBSN-0100Enquire Now2507013810RBSN-0250Enquire Now5008617610RBSN-0500Enquire Now100010122510RBSN-1000Enquire Now200013626010RBSN-2000Enquire Now50001813301RBSN-5000Enquire Now100002274101RBSN-10000Enquire Now200002885051RBSN-20000Enquire NowQuick Product EnquiryYour Name (required) Email (required) Phone (optional) Product / SKU (required) Quantity (optional) Your Message We respond within 24 working hours.Frequently Asked Questions (FAQs)What is the Reagent Bottle with Screw Neck used for?It is used for storing and handling chemical reagents, solvents, and laboratory liquids with secure sealing and easy access.What material is this bottle made from?Constructed from Boro 3.3 borosilicate glass, it provides excellent chemical and thermal resistance.Are different capacity options available?Yes — available in several ml sizes: 50 ml / 100 ml / 250 ml / 500 ml / 1000 ml / 2000 ml.Does it come with a screw cap?Yes — the bottle includes a compatible screw cap for secure closure.
