Package contains: two 500 ml distilling flasks (joint 24/29; ground mouth 14/23) and a 200 mm Graham condenser. Key benefits and features Durable heavyduty construction Glass walls offer light transmittance for easy visual monitoring. heat and temperature resistance with strong chemical resistance. Thermally stable and reusable; less prone to shattering under normal laboratory use. material quality Made from Borosilicate 3.3 glass for low thermal expansion (about onethird that of ordinary glass). Withstands temperatures and rapid temperature changes up to 200 C. Efficient condensation design Graham condenser features an inner spiral surrounded by an outer jacket tube. Vapors flow through the full length of the spiral, maximizing contact with the coolant and improving condensate collection. Clear compatibility and practical performance 500 ml capacity per flask with standard joint size 24/29 and ground mouth 14/23. Includes a 200 mm condenser to integrate with compatible distillation setups. Suitable for routine lab distillation, purification, and related glassware applications. Use scenarios Solvent distillation and purification Ideal for purification of volatile solvents in smallscale synthesis where visual monitoring and reliable condensation are important. Essential oil and natural product processing Suitable for distilling and concentrating plant extracts where efficient condensation and chemical resistance are required. Laboratory reflux and synthesis Works well in simple reflux setups or as part of a larger glassware assembly for reaction workups requiring stable, durable components. Notes for use Ensure proper assembly with compatible joints (24/29) and ground mouth (14/23) fittings. Use appropriate support and clamps as needed to maintain stability during heating.
