Specification list
4-Neck Round-Bottom Flasks are high-quality borosilicate glass vessels designed for chemical synthesis, distillation, reflux applications, and complex laboratory procedures requiring multiple simultaneous connections.
Key Features：
● Premium Borosilicate Glass: Manufactured from high-quality borosilicate glass, providing excellent thermal resistance, superior chemical durability, and reliable long-term laboratory performance.
● Hand-Blown Construction: Expertly hand-blown with a smooth, bubble-free surface, high transparency, and uniform wall thickness to ensure enhanced durability and improved resistance to thermal and mechanical stress.
● Round-Bottom Structure: The round-bottom design promotes uniform heat distribution when used with heating mantles, oil baths, or other heating systems, improving reaction efficiency and experimental consistency.
● Four-Neck Configuration: Designed with four necks to accommodate multiple laboratory accessories simultaneously, including condensers, thermometers, addition funnels, and gas inlet adapters, offering greater flexibility for complex experimental setups.
● Versatile Laboratory Applications: Ideal for distillation, reflux, synthesis, evaporation, and general chemistry applications. Widely used in laboratories, educational institutions, and research facilities.Item Center Joint Side Joint Front Joint Capacity CS-F2110011 14/20 14/20 14/20 100ml CS-F21242L 24/40 24/40 24/40 2000ml CS-F21243L 24/40 24/40 24/40 3000ml CS-F21245L 24/40 24/40 24/40 5000ml CS-F212500 29/42 24/40 24/40 500ml CS-F2125041 29/42 24/40 14/20 500ml CS-F2125049 29/42 24/40 19/22 500ml CS-F21291L 29/42 29/42 29/42 1000ml CS-F21292L 29/42 29/42 29/42 2000ml CS-F21294L1 24/40 19/22 14/20 2000ml CS-F21295L 29/42 29/42 29/42 5000ml CS-F2133L41 34/45 24/40 14/20 3000ml CS-F2133L49 34/45 24/40 19/22 3000ml CS-F2133L81 34/45 29/42 14/20 3000ml CS-F2133L89 34/45 29/42 19/22 3000ml CS-F21341L 34/45 24/40 24/40 1000ml CS-F21342L 34/45 24/40 24/40 2000ml CS-F21343L 34/45 24/40 24/40 3000ml CS-F213500 34/45 24/40 24/40 500ml CS-F2135L41 34/45 24/40 14/20 5000ml CS-F2135L49 34/45 24/40 19/22 5000ml CS-F21381L 34/45 29/42 29/42 1000ml CS-F21382L 34/45 29/42 29/42 2000ml CS-F214000 24/40 24/40 24/40 1000ml CS-F2140011 24/40 14/20 14/20 100ml CS-F214091 24/40 19/22 19/22 1000ml CS-F2140911 24/40 19/22 14/20 1000ml CS-F214190 24/40 19/22 19/22 100ml CS-F2141901 24/40 19/22 14/20 100ml CS-F2141L41 24/40 24/40 14/20 1000ml CS-F2141L49 24/40 24/40 19/22 1000ml CS-F214250 24/40 24/40 24/40 250ml CS-F2142541 24/40 24/40 14/20 250ml CS-F214259 24/40 19/22 19/22 250ml CS-F2142591 24/40 19/22 14/20 250ml CS-F2142L41 24/40 24/40 14/20 2000ml CS-F2142L49 24/40 24/40 19/22 2000ml CS-F2142L99 24/40 19/22 19/22 2000ml CS-F2143L41 24/40 24/40 14/20 3000ml CS-F2143L49 24/40 24/40 19/22 3000ml CS-F214500 24/40 24/40 24/40 500ml CS-F2145041 24/40 24/40 14/20 500ml CS-F2145049 24/40 24/40 19/22 500ml CS-F214591 24/40 19/22 19/22 500ml CS-F2145911 24/40 19/22 14/20 500ml CS-F2145L41 40/50 24/40 14/20 5000ml CS-F2145L44 40/50 24/40 24/40 5000ml CS-F2145L49 40/50 24/40 19/22 5000ml CS-F21541L 45/50 24/40 24/40 1000ml CS-F21542L 45/50 24/40 24/40 2000ml CS-F21543L 45/50 24/40 24/40 3000ml CS-F21545L 45/50 24/40 24/40 5000ml CS-F215500 45/50 24/40 24/40 500ml CS-F21552L 55/50 24/40 24/40 2000ml CS-F21562L 55/50 29/42 29/42 2000ml CS-F21581L 45/50 29/42 29/42 1000ml CS-F21582L 45/50 29/42 29/42 2000ml CS-F21583L 45/50 29/42 29/42 3000ml CS-F21585L 45/50 29/42 29/42 5000ml CS-F2181L41 29/42 24/40 14/20 1000ml CS-F2182L41 29/42 24/40 14/20 2000ml CS-F2182L49 29/42 24/40 19/22 2000ml CS-F2183L41 29/42 24/40 14/20 3000ml CS-F2183L44 29/42 24/40 24/40 3000ml CS-F2183L49 29/42 24/40 19/22 3000ml CS-F21841L 29/42 24/40 24/40 1000ml CS-F21842L 29/42 24/40 24/40 2000ml CS-F21845L 29/42 24/40 24/40 5000ml CS-F218500 29/42 29/42 29/42 500ml CS-F2185L84 29/42 29/42 24/40 5000ml CS-F219140 19/22 14/20 14/20 100ml CS-F219250 19/22 14/20 14/20 250ml CS-F2192591 19/22 19/22 14/20 250ml CS-F2192599 19/22 19/22 19/22 250ml CS-F219500 19/22 14/20 14/20 500ml CS-F2195091 19/22 19/22 14/20 500ml CS-F2195099 19/22 19/22 19/22 500ml
