Stanland Glassblowing Lakes Silver Vacuum Jacketed Oldershaw Distillation Column

Used 35/25 Compact 5 Plate Borosilicate Glass Fractional Distillation Column with Ball Joint and Expansion Bellows

The Stanland Glassblowing Lakes Silver Vacuum Jacketed Oldershaw Distillation Column is a used, compact laboratory fractional distillation column designed for controlled separation of liquid mixtures based on boiling point differences. Constructed from borosilicate glass, this Oldershaw column features 5 perforated plates, 35/25 top and bottom joints, a 35/25 ball joint bottom connection, a silver vacuum jacket, and a corrugated vacuum jacket / expansion bellows design.

This column is a strong choice for laboratories that need efficient fractionation in a shorter glass column format. With a 12.5 inch / 317.5 mm overall length, 1 inch / 25.4 mm inside diameter, and 5 plate design, it offers useful separation performance while remaining easier to integrate into compact laboratory setups than taller 10 plate columns.

An Oldershaw column is a laboratory-scale fractional distillation column that uses perforated plates, also called trays, and downcomers to create repeated vapor-liquid contact. Each plate acts as an individual theoretical stage, helping improve separation precision when working with liquid mixtures that need controlled boiling point fractionation.

This used Stanland Glassblowing Lakes Oldershaw column is well suited for organic chemistry labs, solvent purification workflows, petrochemical testing, essential oil refinement, specialty chemical R&D, pharmaceutical process development, teaching laboratories, and small-scale chemical separation systems.

Compact 5 Plate Oldershaw Column for Laboratory Fractionation

This 5 plate Oldershaw distillation column is designed for laboratories that need improved separation efficiency without the additional height of a longer fractional distillation column. Each internal plate creates a vapor-liquid contact stage, helping separate liquid components according to volatility and boiling point.

The compact 5 plate format is useful when a lab needs more separation than simple distillation, but does not require a taller 10 plate setup. This makes it especially practical for benchtop workflows, specialty glassware assemblies, teaching labs, and smaller-scale method development.

Common uses include:

• solvent purification
• fractional distillation
• reaction product purification
• chemical mixture separation
• boiling point fractionation
• essential oil refinement
• hydrocarbon and petroleum testing
• organic chemistry method development
• small-scale process research
• pharmaceutical and specialty chemical R&D

For labs comparing different column sizes, this unit provides a practical middle ground between simple distillation glassware and taller, higher stage Oldershaw columns.

Silver Vacuum Jacket for Better Thermal Control

This column includes a silver vacuum jacket, which helps reduce heat transfer by radiation. In fractional distillation, temperature stability matters because heat loss can affect reflux behavior, vapor-liquid equilibrium, and separation repeatability.

The silvered vacuum jacket helps create more stable internal column conditions by limiting radiant heat exchange with the surrounding environment.

Benefits of the silver vacuum jacket include:

• reduced radiant heat transfer
• improved thermal isolation
• more stable vapor-liquid equilibrium
• better support for repeatable fractionation
• reduced influence from ambient room temperature
• improved consistency in temperature-sensitive workflows

This makes the column useful for laboratories performing solvent recovery, specialty chemical purification, hydrocarbon fractionation, or boiling point separation where thermal consistency helps improve workflow reliability.

35/25 Joints with Ball Joint Bottom Connection

This Stanland Glassblowing Lakes Oldershaw column includes 35/25 top and bottom joints, with the bottom listed as a 35/25 ball joint. Ball joints are helpful in laboratory glassware assemblies because they allow more alignment flexibility than rigid taper joints.

This can be valuable in custom or specialty setups where connected glassware may not align perfectly.

The 35/25 ball joint configuration may support:

• custom fractional distillation assemblies
• vapor transfer systems
• reflux setups
• compact glassware arrangements
• chemical process development systems
• specialty purification workflows
• pilot-scale laboratory glassware setups

Before purchase, buyers should confirm compatibility with their existing flasks, condensers, receivers, adapters, clamps, and vacuum glassware.

Borosilicate Glass Construction for Research and Purification Workflows

This Oldershaw distillation column is constructed from borosilicate glass, a preferred material for laboratory distillation and chemical processing glassware because it offers chemical resistance, thermal stability, and clear visibility.

Borosilicate glass benefits include:

• compatibility with many laboratory solvents and reagents
• visibility of internal vapor liquid activity
• thermal stability during heating and cooling cycles
• suitability for repeated laboratory use
• usefulness in research, QA/QC, and teaching environments

Clear glass construction also allows users to observe column behavior during operation, which can be helpful for troubleshooting flooding, reflux behavior, vapor movement, and fractionation performance.

Expansion Bellows / Corrugated Vacuum Jacket Design

This used column includes a corrugated vacuum jacket or expansion bellows. This feature helps accommodate thermal expansion and contraction during heating and cooling cycles, reducing stress on the glass jacket.

Benefits of the expansion bellows design include:

• reduced thermal stress on vacuum jacketed glass
• improved durability during repeated use
• support for heating and cooling workflows
• added flexibility compared with rigid jacketed glassware
• improved long-term usability in laboratory distillation setups

For laboratories that run repeated purification or distillation methods, the expansion bellows design can help support more dependable operation over time.

Technical Specifications

Typical Applications

The Stanland Glassblowing Lakes 35/25 5 Plate Silver Vacuum Jacketed Oldershaw Distillation Column is useful for laboratories that need compact, efficient fractional distillation glassware.

Common applications include:

• solvent purification
• solvent recovery workflows
• fractional distillation of liquid mixtures
• reaction product purification
• boiling point separation
• essential oil separation
• hydrocarbon and petroleum testing
• pharmaceutical process development
• organic chemistry research
• specialty chemical R&D
• small-scale process optimization
• academic teaching labs
• QA/QC method development

This column is especially useful for workflows where a simple distillation adapter is not efficient enough, but a taller 10 plate column may be more than the setup requires.

Why This Stanland Oldershaw Column Stands Out

This column stands out because it combines compact size, 5 plate fractional distillation performance, silver vacuum jacket thermal control, and a 35/25 ball joint connection in one specialty glassware component.

For laboratories comparing multiple Oldershaw columns, this unit is a strong fit when the buyer needs:

• a shorter 12.5 inch column
• 5 theoretical stages instead of a taller 10 plate design
• a 1 inch internal diameter
• silver vacuum jacket thermal isolation
• ball joint flexibility
• borosilicate glass construction
• used equipment value

This makes the column especially attractive for labs with limited setup space, custom glassware assemblies, or smaller scale distillation workflows.
