Exceptional Chemical and Thermal Resistance

Constructed from optically clear borosilicate glass 3.3, the unit offers outstanding resistance to chemical attack and thermal shock. This makes it suitable for a diverse range of process media and ensures long-term durability under demanding laboratory or pilot plant conditions.

Flexible and Modular Design

The system is available in standard reactor volumes from 1 to 10 liters, with modular sections for reactors, columns, condensers, and receivers. Leak-proof ground joint connections facilitate easy assembly, quick cleaning, and efficient customization to suit specific distillation or reaction requirements.

Precise Reflux Ratio and Temperature Control

A manually adjustable three-way valve enables accurate reflux ratio control, and the included heating bath (with optional temperature controller) allows stable operation across a wide temperature span (-50C to +200C). This supports a broad gamut of chemical processes needing tight process control.

FAQ's of REFLUX REACTION CUM DISTILLATION UNIT:

Q: How does the reflux ratio control work on this unit?

A: The reflux ratio is adjusted manually by a three-way valve located in the reflux path. This allows you to control the proportion of condensed liquid returned to the column versus collected in the receiver, providing the flexibility necessary for effective separation during distillation.

Q: What types of condensers are supplied with the unit?

A: You can choose either a double coil Allihn condenser or a vertical Liebig condenser, both made from borosilicate glass 3.3. These condensers offer high thermal efficiency and ensure effective condensation even under varying temperature and pressure conditions.

Q: Where can the Reflux Reaction Cum Distillation Unit be used?

A: This unit is suitable for use in chemical laboratories, research facilities, pilot plants, and industrial settings wherever process development, solvent recovery, or chemical distillation is required. Its corrosion-resistant, modular structure and ground glass joints simplify installation and maintenance.

Q: What safety features are integrated into the design?

A: For enhanced safety, the unit incorporates PTFE liners in all valves, a break-resistant glass design, an over-pressure safety vent, and leak-proof ground glass joints, all of which reduce operational hazards and ensure reliable performance.

Q: How do I clean and maintain the glassware?

A: Each glass component has a smooth, polished finish, making the surfaces easy to clean. Disassembly is straightforward due to the modular nature of the unit. Use appropriate laboratory glassware cleaning solutions and handle with care to preserve clarity and mechanical properties.

Q: What are the benefits of using borosilicate glass 3.3 in this unit?

A: Borosilicate glass 3.3 offers high transparency, excellent chemical and thermal shock resistance, and compliance with ISO 3585 and ASTM E438 standards. This ensures minimal contamination, durable performance, and clear process visibility.
