Heidolph 036130000 Test Tube Shaker with Vibrating Reax Top Speed Range 100 – 2,500 rpm; 200 – 3,20 (more)0 rpm Orbit 5 mm Motion Circular Vibrating Features - Ideal for simple mixing tasks, enhancing lab efficiency - Short-term operation mode activated by pressure on the test tube tray - Continuous operation dissolves persistent cell pellets gently yet powerfully - Achieves speeds up to 3,200 rpm for thorough mixing - 5 mm shaking orbit ensures uniform distribution and homogenization of viscous media - Equipped with overheat protection to ensure safety - Provides IP 22 protection against the ingress of solids and liquids - Simple scale with reference points for precise speed control This model is particularly suitable for simple mixing tasks. In short-term operation mode, the shaking motion is triggered by pressure on the test tube tray. This mode is suitable for mixing up solutions, for example. Persistent cell pellets can be dissolved gently but powerfully in continuous operation. With a speed of up to 3,200 rpm and a shaking orbit of 5 mm, reliable and uniform distribution of solids, and homogenization of highly viscous media are guaranteed.

F1 class mass standards are exceptional measuring tools that represent the pinnacle of precision in  (more)the field of metrology. Classified as F1 metrology class, they are perfect for advanced applications where every detail of measurement is of paramount importance. F1 class standard: stainless steel wire Nominal value: 1 mg Material: stainless steel Highest Precision and Accuracy F1 class mass standards are characterized by absolute measurement precision and extraordinary accuracy. They are designed to meet the most stringent standards for acceptable deviation from actual weight. Stability under Difficult Conditions An important feature of F1 class mass standards is their ability to maintain measurement stability even under harsh environmental conditions. The standards of this class are resistant to changes in temperature, humidity and other factors that affect the precision of measurements. Calibration in Accordance with International Standards The calibration process for F1-class mass standards is rigorous and in accordance with international standards. This ensures that standards of this class are globally recognized and can be used in different countries. Specialized Construction Materials F1-class standards are often made of materials with unique physical properties. This provides them not only with precision, but also with durability and wear resistance. Applications 1. Industrial Metrology F1 class mass standards are used in metrology laboratories engaged in the testing and maintenance of measurement standards. 2. Scientific Research In scientific research, especially in high-precision fields such as physics and astronomy, F1-class mass standards are a key tool. 3. Aerospace Industry In the precision mass measurements required by the aerospace industry, F1-class standards guarantee reliability and accuracy. 4. Calibration Laboratories In calibration laboratories where uniformity and precision are a priority, F1-class mass standards are the standard of excellence. F1-class mass standards are synonymous with the highest quality and precision in the field of metrology. Their use is crucial where even the slightest deviation from the standard can carry unpleasant consequences. They are tools for advanced applications that contribute to raising standards in the field of mass measurement.
