Background, typical uses and selection points for this product. We can send model drawings, technical data and samples to support your evaluation.
A safety-coated bottle is a laboratory glass bottle bonded inside a tough plastic coating. If the bottle is dropped or cracks, the coating is designed to hold the broken glass together and contain the liquid instead of letting it scatter and spill, a real safety benefit when the contents are corrosive, toxic or too valuable to lose.
It combines the chemical inertness and clarity of glass with an extra layer of mechanical and spill protection.
Coated bottles are specified for storing and moving hazardous and corrosive liquids, solvents and acids, and high-value samples. You’ll find them in pilot plants and process areas, field and mobile labs, industrial chemistry labs and any stockroom where a dropped bottle is a serious incident. They are also a practical choice for carrying reagents between buildings or along corridors where a bare glass bottle could break on a fall.
The core is a borosilicate 3.3 bottle with a GL45 or narrow-mouth thread, or a ground-glass joint, bonded inside a translucent PVC or PE coating. The coating retains fragments and slows leakage on breakage while leaving the contents visible and the fill level readable. Closures are polypropylene screw caps with PTFE liners or ground-glass stoppers. Because the coating has its own temperature limit, coated bottles are generally not autoclaved like bare glass.
Treat the coating as a secondary safeguard, not a reason to handle bottles less carefully. Keep within the coating’s rated temperature range, which usually rules out autoclaving and hot filling. Inspect the coating regularly; cuts, blisters or peeling mean it can no longer be relied on to contain a breakage. We supply the rated temperature range for each coated model so your safety team can set handling rules.
We start from a formed and annealed borosilicate bottle, then apply the safety coating by dipping or sleeving and cure it onto the glass. Coating coverage, adhesion and the underlying thread or joint fit are checked in production. Options include clear or amber glass, GL45 or narrow-neck finishes, colored caps, printed hazard labels and pouring or dispensing caps. Send us your capacities and closure needs for a quote.
Customization
We specify the container, closure, decoration and transit packing as one package, so every part fits and arrives ready for your filling line.
Choose from standard sizes or request a custom capacity. We supply drawings with tolerances, label panel dimensions and nominal and brimful capacity.
We match caps, liners, pumps, droppers and stoppers to the neck finish and check the seal against your contents and filling process.
Flint, amber and colored glass, with frosting, spray coating, screen printing, hot stamping or labels. Material documentation is available on request.
Partitioned cartons, layer pads or bulk pallets, with shipping marks and pallet patterns planned for your route and warehouse.
Applications
Typical markets and uses. Tell us your contents, filling process and storage conditions and we will recommend the right model and components.
We confirm availability of the standard model, and review any changes to size, color, decoration or tooling for feasibility and lead time.
We send samples and specification sheets so you can check dimensions, component fit and finish before you place the order.
Your quotation covers packing design, shipping route, Incoterms and export documents, so landed cost is clear from the start.
