Walter Magic Programmable Mixer is a combination of a variable speed rotator, and an advanced multiple tube vortex, in one machine. It can hold tubes which range from 0.2ml to 50ml, and all kinds of different tube holders can be assembled into one rack. The mixer can be used in ambient temperatures from 4°C to 65°C, making it ideal for a variety of laboratory settings such molecular biology, biochemistry, clinical and histochemistry. Its large LCD screen shows the information clearly, and 2 additional custom programs (6 segments per program) can be created easily. It has 10 different programs for rotation and mixing, as well as 360° rotation and 0-360° mixing angles available for your convenience. It is small enough to fit on a crowded bench, and can easily be moved to adapt to your laboratory needs. It is also cold room and incubator compatible, making it versatile in many conditions.
