Gentlemen/ Comrades ! This vacuum pump is perfect for rotary evaporator, and for soft (40-50 Hgmm) vacuum distillation, and circulating water in your reflux condenser. The operating noise about 50-65 dB , about sound like a quieter vacuum cleaner. First usage: fill it about 12-14 liter distilled water. Watch often for algae species :D It was shipped by UPS for free of charge shipping. This guy was helpful. It wrote only 90 $ on the customs declaration for the item price. But unfortunatelly doesn't provide the guy english manual, only chinese, but scan it and the g---le translator will be your friend. :D I'm satisfy now this product.
