Overview
Introducing the Glass Oven G-300, BUCHI’s all-in-one instrument for small samples. With interchangeable accessories, the Glass Oven G-300 can perform distillation, drying, sublimation, and freeze-drying, eliminating the need for multiple large instruments. Its compact size even allows placement in a glovebox for safe handling of air-sensitive samples.

Key facts

• Available accessories: Drying, distillation, sublimation and freeze drying
• Heating temperature: up to 300 °C
• Volume: Drying: up to 250 mL (sample vol.); Distillation: 5–40 mL (flask size)

Benefits

• All-in-one solution: interchangeable accessories let a single compact instrument perform multiple methods (drying, distillation, sublimation, freeze-drying)
• Effortless savings: compact design for efficient processing of small samples, reducing energy waste and footprint
• Gentle sample processing: semiconductor-coated heating for uniform temperature distribution and fast heating/cooling, enabling visual monitoring of samples through the transparent chamber

Features

• Distillation: perform simple and fractional distillations of small liquid volumes using a bulb-to-bulb condensation arrangement; extend number of bulbs (up to four) to separate multiple fractions; cooling tray option for low-boiling substances
• Drying: gentle and efficient drying of small samples up to 300 °C; drying possible under vacuum for heat-sensitive samples
• Drying under rotation: rotation drying flask accessory keeps samples in motion to avoid crust formation and speed drying
• Freeze drying: freeze samples then reduce pressure to sublimate ice; requires the freeze-drying accessory plus condenser or cold trap
• Sublimation: solid-to-gas transition without liquid phase to obtain pure products; requires sublimation accessory

Interchangeable accessories (examples)

• Sublimation finger (accessory)
• Drying accessory glass (incl. stopcock, flange ring, O-ring)
• Glass ball tubes (multiple bulbs) for multi-fraction distillation
• Rotation drying flask (e.g. 30 mL) for drying under rotation
• Freeze drying accessory (requires condenser or cold trap)
• Kugelrohr accessory (incl. drive unit and cooling unit) to convert drying config to Kugelrohr

Applications

• Environmental analysis: sample preparation for monitoring pollution (Soxhlet extraction, concentration)
• Food & beverage: QC, ingredient development; distillation, concentration, drying workflows
• Chemical industry: QC and R&D — concentration, reflux reactions, recrystallization and more
• Pharmaceuticals: QC and lab-scale formulation work — distillation, concentration, drying
• Academia & education: versatile teaching instrument supporting a range of evaporation applications
• Feed industry: QC and ingredient development workflows
