IKA R 1312 Turbine Stirrer

IR sensor, VELP patent VELP Scientifica is the only company in the world to supply the technological (more) and revolutionary IR system: as soon as the test tube is detected by the sensor, the latter automatically activates the instrument, without the need for any pressure from the laboratory technician. Compared to the classic pressure mode, the patented IR sensor system guarantees a drastic reduction of the stresses perceived by the operator, increasing the comfort of the working environment. Digital Display, Better Communication and High Repeatability Simple and extremely bright digital display, easy to read and practical, with all the most important parameters such as stirring speed, time and operating mode shown on the main screen. Improved communication translates into greater efficiency. High stability on the bench 4 non-slip feet and zamak base guarantee considerable stability on the bench, making the instrument usable on many surfaces. The highly innovative ergonomic design also plays a major role.
