TECHTONGDA® 110V 2L Rotary Evaporator Rotavapor with Digital Screen Heating Bath Lab Equipme Specification: Model RE-201 Capacity of evaporating flask 1L Capacity of collecting flask 1L Vacuum -0.098Mpa Rotating speed 0 - 120 R/min Evaporating speed ≥1.5L/H20 Temperature range Room temperature-99℃ Motor power 40W Water bathing power 1000W Voltage 110V A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g. "the sample was evaporated under reduced pressure"). Rotary evaporators are also used in molecular cooking for the preparation of distillates and extracts. Foam removal method: 1. Condenser bottle mouth downward to let the foam out by itself. 2. Do not shake the condenser when there is a small amount of foam left in the condenser. Shaking is easy to damage the glass tube in the condenser. An acidic liquid can be poured into the condenser to dissolve the foam. Features: Rotator consist of a group of reliable micro motor and integrated circuit control device. Under the effect of the electronic speed regulation, it can be rotated stably within the range of 10-120rpm, reaching the international advanced level 1. Special fluoro rubber sealing, high corrosion resistance. 2. High evaporating efficiency & high recovery. 3. Modular design, easy to connect to other appliance. 4. Easy to install and disassemble, easy to operate & maintain. 5. The main body extensively adopts stainless steel and aluminum alloy, firm and beautiful 6. RE-201 rotary evaporator's heating bath is lifed manually, lifting distance is 120mm 7. Two kinds of condenser structures for choosing, one adopts double line convection principle, used for inorganic solvent evaporation. The other is a single line container with a interlayer cooled by water and dry ice, used or evaporating the organic solvent. Using vertical condenser to save space. 8. The rotating shaft using high borosilicate glass, the joints using fluorine rubber framework oil seal to seal, high tightness and better effect Packaging: hipping & Handling Details Default Shipping Cost or Free Shipping Information: ▲ Default shipping cost or free shipping service is only for the lower 48 United States by UPS Ground or USPS.
