Efficient Fractional Distillation: Provides multiple theoretical plates for better separation of close-boiling liquid mixtures. Excellent Thermal Shock Resistance: Withstands typical laboratory temperature changes without cracking. Chemical Resistance: Resists most common acids, bases, solvents, and reagents under normal laboratory conditions. Clear Borosilicate Construction: Allows easy visual monitoring of reflux and distillation progress. Uniform Wall Thickness: Promotes even heating and reduces stress points for enhanced durability. Reusable and Long-Lasting: Designed for repeated use with proper handling and care. Versatile Applications: Ideal for fractional distillation, reflux, purification, synthesis, and general chemistry procedures. Length: Available in 100mm, 200mm, 250mm, 300mm, 400mm, 500mm and 600mm. Package Includes: Vigreux Distillation Column (selected length, 29/42 joints).
