Glass-Lined Steel Advantages

Corrosion Resistance― Acids and alkalis

― Exceptions: hydrofluoric acid and hot concentrated phosphoric acid

Anti-Adhesion― Many substances that stick to metal will not stick to

glass

Purity― High quality standards for food and drug applications

High operating temperatures and pressures― -50°C to >260°C

― FV to 100/150 psig

Heat Transfer Capability― Ability to add or remove heat to the batch

Combination Glass/Glass-Lined Steel Advantages

“Best of both worlds”― Reactor body constructed in strong,

corrosion resistant glass-lined steel ― Glass cover, features the same corrosion

resistance but additional visibility  Maximum purity Optimized heat and mass transfer Suitable for GMP use Designed for a compact layout with

reduced headroom requirements

Materials used for glass-lined steel repair

Polytetrafluoroethylene (PTFE) – Plastic material inert to virtually all chemicals– Superior non-stick properties– Material used for nozzle repair sleeves for glass-lined

reactors Tantalum

– Tough, ductile metal– Used in corrosion resistant applications in environments

no other metal can withstand (resistance very similar to glass)

– Often used with glass-lined steel reactors as patches, dip tubes, piping and overhead condensers.
