This Deschem glass recovery flask is a serious piece of lab equipment! It's a 3000ml (3 litre) flask with a 24/40 joint, perfect for rotary evaporators and Kjelda applications. The best part? It's made from Borosilicate Glass 3.3, which is super durable and resistant to thermal shock. The annealing point is 560°C, softening point is 820°C, and it has a linear coefficient of expansion of 32×10-7/°C - basically, this flask can handle some serious temperature changes without cracking. It's transparent, so you can easily monitor your reactions or solutions. The joint is standard 24/40, making it compatible with lots of other lab glassware. Whether you're in a professional laboratory, educational setting, or doing some serious home chemistry, this recovery flask is built to perform. The quality of borosilicate glass means it's less likely to break from sudden temperature changes compared to regular glass. It's essential for distillation setups, evaporation processes, or any application where you need to recover solvents or concentrate solutions. The workmanship is precise, and the flask feels substantial in hand. If you need reliable glassware that won't let you down during important procedures, this is definitely worth considering. Lab pros will appreciate the specifications, and students will benefit from the durability. Solid equipment for serious science!
