Package contents 2 × 500 mL distilling flasks (each with 24/29 standard taper joint) 1 × 200 mm Graham condenser with 19/26 ground mouth Key benefits — why you need this set Ready-to-use distillation assembly: two 500 mL flasks plus a 200 mm Graham condenser provide the core pieces for small-scale distillation, reflux, and solvent recovery. Durable, lab-grade construction: borosilicate 3.3 glass and heavy-duty wall thickness reduce the risk of breakage and improve long-term reusability. Efficient condensation and recovery: the Graham condenser’s inner spiral forces vapors through the full length of the coil for prolonged contact with coolant, maximising condensate yield and improving cooling efficiency. Material and performance Borosilicate 3.3 glass: very low coefficient of thermal expansion (about one-third that of ordinary glass), offering superior resistance to thermal shock and improved dimensional stability during heating and cooling. High temperature and chemical resistance: good resistance to common laboratory reagents and stable performance under high-temperature conditions. High light transmittance: clear glass for easy visual monitoring of reactions and condensate flow. Compatibility and dimensions Flask volume: 500 mL each Flask joint: 24/29 standard taper Condenser length: 200 mm Condenser ground mouth: 19/26 Designed to fit common laboratory glassware joints and standard laboratory setups using 24/29 and 19/26 connections. Practical applications (examples) Small-scale distillation of solvents in organic synthesis labs. Reflux operations and solvent recovery during sample preparation and purification. Educational laboratory demonstrations of condensation and distillation principles. What sets this product apart Combination of durable borosilicate 3.3 glass, heavy-duty walls, and a Graham condenser design gives reliable thermal performance, improved condensate collection, and long service life while maintaining compatibility with standard lab glassware joints.
