CENTRIFUGAL VACUUM CONCENTRATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a centrifugal vacuum concentration device which directly and uniformly heats a sample solution and efficiently condenses and dries the sample solution in a short time.SOLUTION: A centrifugal vacuum concentration device includes: a cup shaped vacuum vessel 11 having a lid member 11a for opening and closing an upper opening; a metal rotary heating element 12 which is rotatably provided in the vacuum vessel; rotary driving means 13 which rotates the rotary heating element; exhaust means 14 which decompresses the vacuum vessel; a sample vessel holding part 15 provided at the rotary heating element; and a magnet 16 which generates an eddy current in the rotary heating element by electromagnetic induction to cause the rotary heating element to produce heat; a non-contact temperature sensor 17 which detects a temperature of the rotary heating element; and magnet position adjusting means 18 which adjusts a position of the magnet relative to the rotary heating element.
