Also come standard is the new plexiglass bath cover. Specially designed for Ai 20L SolventVap rotary evaporators, this beneficial cover securely rests on top of the water bath and ensures the best possible temperature uniformity.\u003c\/p\u003e\n\u003cp\u003eA rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The process of rotary evaporation is most often used to separate solvents with low boiling points, such a n-hexane or ethyl acetate, from compounds which are solid at room temperature and pressure. However, careful application also allows for the removal of a solvent from a sample containing a liquid compound, if there is minimal co-evaporation (azeotropic behavior) and a sufficient difference in boiling points at the chosen temperature and reduced pressure.\u003c\/p\u003e\n\u003cp\u003e    \u003c\/p\u003e\n\u003cp\u003eExample:The following table is a list of a variety of substances ordered by increasing vapor pressure (in absolute units).\u003c\/p\u003e\n\u003cp\u003eThe newly re-designed \u003cstrong\u003eAi SolventVap 5.3-gallon\/20L\/0.7 cu ft (evaporating flask capacity) series\u003c\/strong\u003e rotary evaporators come with all PTFE valves for solvent-resistant operations. We also lowered the height of assembled unit, for easy installation and ease of use and storage. Also come with them are vertical glassware and digital temperature\/rotation control. Its optimized bath volume allows for rapid heat-up times. The condenser unit has specially designed glass tubes that utilize surface area extremely efficiently. That’s why our SolventVap evaporators consistently deliver reliable and reproducible process results that are usually reserved for more costly systems. Another important aspect of the SolventVap is the safety features, which includes dry-run protection, water bath over-temperature shut-off protection, and fuse protection.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRotary evaporator\u003c\/strong\u003e features a specially designed motor and worm gear, which provides constant rotation at speeds from 10 to 130 rpm. As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation, which is caused by the gentle heating from the water bath. The rotating system is fitted with a special seal that allows the apparatus to be placed under vacuum, effectively reducing the boiling point of the solvents and removing the vapor phase, making the process much more efficient. Each unit is also equipped with an easy-to-use vacuum release and a continuous feed system, which allows solvent to be constantly drawn into the rotating flask without needing to stop the operation. \u003cstrong\u003eDigital water bath\u003c\/strong\u003e operates from ambient temperature to 99°C (210°F) with PID temperature control stepping at 0.1°C increments. Heating coils are located directly inside the pan for the most efficient heating possible. A built-in overheat protector will shut down power, should the controller fail. \u003cstrong\u003eStandard Glassware Set\u003c\/strong\u003e includes 5.28 gallon (20 liters) round-bottomed evaporating flask, 2.64 gallon (10 liters) round-bottomed receiving flask, and vertical condenser.

Please use caution when operating. Users of glass reaction equipment must take all necessary precautions to avoid contact with rotating parts, particularly entanglement of loose clothing, hair, necklaces, or other jewelry. Under these circumstances, the winding action of the rotating parts can draw the user(s) into the apparatus, resulting in breakage of glassware, burns, and\/or chemical exposure. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable width=\"693\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e Electrical requirements\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e 220V 50\/60Hz single phase, 20A, 4300 watt (rotation motor: 300 watts)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e Glass material\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e High borosilicate glass 3.3\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e Evaporating flask\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e Capacity: 5.28 gallon (20 liters or 0.7 cu ft)  Maximum load: Not to exceed 60% of the flask's capacity  Sealing flange: 4.9\" diameter  Rotation speed: 10 to 130 rpm  Evaporating speed: 1 gallon\/hour (water), 2 gallon\/hour (alcohol)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e Receiving flask\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e 2.64 gallon (10 liters or 0.35 cu ft)\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e Condenser\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e Glassware: Main + auxiliary triple-circulating cold traps, vertical  Chilling fluid conneciton: 3\/8\" hose barb x 4 (2 on main + 2 on auxiliary)  Condensing surface    Main condenser: 9,480 cm\u003csup\u003e2\u003c\/sup\u003e or 10.2 sq ft    Auxiliary condenser: 3,580 cm\u003csup\u003e2\u003c\/sup\u003e or 3.9 sq ft\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e Working environment\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e 5 to 95°F\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e Water bath\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e Temperature range: ambient to 99°C (210°F)  Temperature controller: digital  Dimensions: 17.5\" diameter x 9.8\" depth x 12\" height  Material: stainless steel  Media: distilled water only  Max. water level: not to exceed 1\" from the top rim of the bath  Number of heaters: two  Drain port: one  Exterior liner: rubber  Lifting: motorized  Maximum lifting distance: 7.5 inches\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e Vacuum\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e Level: \u0026lt;
