Buchi Glass Cylinder Unit 20ml 11059761

Glass Cylinder Unit, 20 mL, is a glass accessory designed for bulb‑to‑bulb/fractional distillation of small liquid volumes in BUCHI glass ovens. The unit contains three 20 mL glass bulbs (balls), a vapor duct and retaining clips to enable distillation and separation of up to three fractions within a single distillation run. It is intended for use as an interchangeable accessory with BUCHI Glass Oven models (for example G‑300 and compatible Kugelrohr configurations) to perform fractional distillation on samples in the 5–40 mL flask size range.

Key Features:

• Unit volume per bulb: 20 mL
• Contains three glass bulbs (three fractions)
• Includes vapor duct and retaining clips
• Designed as an accessory for BUCHI Glass Oven (e.g., G‑300 / Kugelrohr configurations)
• Intended for fractional distillation of small liquid volumes (fits flask sizes 5–40 mL range)

Advantages:

• Enables separation of up to three fractions in a single distillation, increasing process efficiency
• Interchangeable accessory design adds versatility to BUCHI Glass Oven systems for distillation applications
• Compact glass configuration suited for small sample volumes, reducing solvent use and heating time
