BUCHI B-491 is a reliable and easy to use laboratory accessory for distilling, extracting and purifying liquids. It is a two-piece set consisting of a lower flask-like condensation vessel and an upper round-bottomed boiling flask. Both the flasks have separate borosilicate glass fabrication and are secured tightly together using a B-491 clamp. BUCHI B-491 also features a drain valve at the lower end of the condensation flask used to easily take the condensed liquid out of the flask. The main body of B-491 comprises of a double-jacketed cylindrical distillation column. This column is provided with wall sockets controlled by a thermometer, for the purpose of controlling and precisely adjusting the temperature of the contents. The device is also equipped with a series of sintered glass bubblers, which help to actively remove a large volume of vapors and gases and hence reduce the chance of corrosion. BUCHI B-491 is also fitted with a unique boiling flask design which allows greater separation between the flasks, thus resulting in improved heating efficiency and increased capacity. The round-bottomed boiling flask is also made of borosilicate glass, making it highly resistant to heat and to maintain chemical integrity of the liquid. B-491 also features a highly precise heating mantle which allows for accurate temperature control and is extremely easy to clean. BUCHI B-491 also comes with a B-495 clamp which is designed to secure the flasks tightly together. The purpose of this clamp is to reduce the risk of seepage of the volatile material during the distillation process. Besides its function as a secure clamping device, it also serves as a support for the thermometer. Lastly, B-491 is equipped with a ground glass joint which facilitates the connection of the boiling flask and condensation flask without the use of adhesive agents. This helps avoid contamination and leakage, making it a safe and efficient device for handling hazardous liquids in laboratories. All-in-all, BUCHI B-491 distilled flask set is an efficient and reliable laboratory accessory. It's sturdy construction, functional features, and easy to use design make it the perfect choice for laboratory personnel to utilize when distilling and purifying liquids
