VELP Electromagnetic Stirrer - Stirrer Principle

     Horsepower = torque multiplied by speed

      The stronger the torque, the weaker the speed

      Torque speed is always inversely proportional

PID software controls the temperature adjustment to achieve fast, accurate and stable temperature control. The maximum temperature control accuracy of the heating stirrer can reach 370°C, and the precise temperature setting has a resolution of 1°C.

The powerful brushless engine is capable of revving from 30 RPM to 1700 RPM (5 RPM per stage) and can carry up to 20 liter flasks. Torque compensation technology SpeedServo™ helps keep the rotational speed constant under viscosity changes. Alnicon magnets provide the most advanced The latest magnetic coupling technology ensures easy and uniform stirring around the environment.

It has a timer for unattended operation and automatic reverse selection of the stirring direction to make the sample temperature more uniform and the mixing more uniform.

MultiAluBlock™ and new MonoAluBlock™ allow many reactions to be performed, saving time and bench space, new heating pack settings allow oil baths and masks to be changed for clean and safe reactions with round bottom flasks, PTFE safety lids are designed for To minimize heat dissipation and increase safety, Tengyi Technology provides you with the most suitable heating mixer and laboratory equipment solutions.

The VELP DC mixer OHS 200 Advance is VELP's highest specification mixer and is designed to ensure the highest safety standards. The robust sealed housing and IP 54 protection rating ensure durability even in the harshest environments. Integrated safety alarms for overload, overheating and overcurrent will maintain performance in the long term by stopping stirring, safe start and stop knob operation and locking keys avoid accidental starts and changes in working conditions, the OHS 200 DC stirrer has different sensitivity levels integrated The vibration sensor will stop operation and notify you. Make sure the OHS is stable and properly secured, the OHS 200 Advance ensures continuous operation and comes with a 2-year warranty.

The best-in-class stirring power of VELP OHS 200 Advance is the ideal solution for demanding applications with viscosity requirements up to 100.000 mPas. The electronically controlled brushless motor of the OHS 200 Advance DC mixer can stir up to 200 liters (maximum torque of 200 Ncm) and ensures the longest service life, and SpeedServo TM torque compensation technology automatically adjusts the speed according to viscosity changes to keep it constant , it provides optimal performance in both high-torque and high-flow operations thanks to two variable speed gears: Variable Gear 1: 6-400 rpm, Variable Gear 2: 30-2000 rpm, constant rotation at any speed Torque, brushless motor and microprocessor ensure outstanding performance that marks the difference between conventional blenders and the VELP VELP OHS series. Torque remains stable throughout the entire speed range, ensuring even at the highest speeds. Stirring at maximum torque is a very important parameter for test repeatability. A dedicated section of the screen provides precise torque measurement so you can monitor changes in torque power in real time during the test.

Removal of Colloidal Particles from Water Jar Test
In tap water treatment, there is a procedure called medicated coagulation. As the name suggests, chemicals need to be added into our treated water, but what are the functions of these added chemicals?

In the experiment of coagulation dosing, we will first prepare the same volume of water in a beaker, and then add it to the water at the same time according to different dosages. Then use a stirrer to quickly mix the coagulant and water, and then let it sit for a period of time. We You can clearly observe the generation of particulate matter from outside the cup, which accumulates at the bottom of the cup and bottle as time goes by. Finally, by analyzing the water in the upper layer, you can find the cleanest test water. This experiment is also a common "cup and bottle" experiment in water treatment. Jar test.

After this series of addition tests, the optimal addition amount can be known. This will not only effectively remove invisible colloidal particles from the water, but also reduce excess additives and be used in the purification unit of the water plant. . In addition, we will fine-tune the amount of medicine added depending on the turbidity of the monitored source water. This also shows that small experiments (cup and bottle tests) are still needed to find the most suitable conditions for different water quality conditions.
