Product Knowledge
Background, typical uses and selection points for this product. We can send model drawings, technical data and samples to support your evaluation.
Many reactions run under pressure or at high temperature in a metal reactor or autoclave, but the metal can contaminate sensitive products or be attacked by aggressive chemistry. A glass liner solves both problems: it sits inside the metal vessel and gives the reaction an inert borosilicate surface, while the metal vessel still provides the pressure containment.
The product touches only glass, and the reactor body is protected from corrosion.
Glass liners are used for pressure-reactor synthesis, hydrothermal and solvothermal reactions, reactions in corrosive media, trace-sensitive synthesis and catalysis research. Typical buyers are pharmaceutical process development labs, catalysis and materials science groups, and pilot-scale chemistry teams that run benchtop pressure reactors and want faster cleaning between runs and less metal contamination. Spare liners also let one reactor switch between chemistries without cross-contamination.
Each liner is an open borosilicate 3.3 cylinder with a flat or rounded base and a finished rim, sized to fit the cavity of a specific reactor or autoclave. The outside diameter, height and rim are matched to the vessel so the liner seats correctly and the head closes over it, with clearance for stirrers, thermowells and dip tubes where needed.
The liner is not a pressure vessel itself; pressure and temperature limits come from the reactor system. Fit the liner only to the reactor it was made for, heat and cool gradually to avoid thermal shock, and keep the fill level below the rim so liquid doesn’t reach the metal walls. Inspect for scratches and cracks between runs, since a damaged liner can fail and expose the metal to the reaction.
We form the liners from borosilicate 3.3 tubing or blown glass, finish the rim and base, and anneal each piece. Dimensional accuracy and wall integrity are the key checks, since the liner has to fit the reactor closely. Most liners are made to the customer’s reactor model, so send us the reactor make and model or a cavity drawing and we’ll produce a drawing and samples for sign-off.
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.
