OHS 100 Digital Overhead stirrer VELP-cover
OHS 100 Digital Overhead stirrer VELP

OHS are designed to ensure the highest safety standards. The resistant sealed case and the IP 54 deg (more)ree of protection guarantee durability over time even in the most aggressive environments. Continuous trouble-free operation in your lab, backed by a 3-year extended warranty. Constant torque at any speed The powerful brushless motor and microprocessor control ensure unprecedented performance, highlighting the difference between a conventional shaft stirrer and VELP OHS Series shaft stirrers. Thanks to the SpeedServo feedback system, the torque remains constant at any speed, even at maximum. Always having a constant torque is a very important parameter for the reproducibility of the analyses. SmartChuck Technology: Inserting or Removing an Auction Has Never Been So Simple! How often do you have to remove or replace the stirring rod using two hands and see the rod drop into the liquid? SmartChuck™ technology makes this activity quick and easy with just one hand and no special accessories. Two simple movements allow you to unlock the protective ring and remove or replace the stirring rod. If the protection ring is opened during the analysis, the instrument interrupts the stirring, showing a safety message on the display. Maximum Protection and Security OHS Advances guarantee the highest safety standards. The IP54 degree of protection ensures maximum protection of the instrument from corrosion and high performance in challenging work environments. The stirring is activated through pressure, avoiding involuntary start-ups and the set speed is reached gradually. The large number of sensors and safety controls deactivate the stirring in case of overload, overheating or short circuit. Integrated Timer to Schedule Your Activities The OHS Digitals are equipped with timers that allow you to program the stirrer according to your needs and to carry out the reactions independently. Setting the timer is quick and easy, just press the dedicated button and select a time interval between 1 min and 99:59 hours. The OHS allow you to choose between two different control panels, Digital or Advanced, to better suit the needs of your laboratory. - Digital: precise speed settings; torque indicator; integrated timer. - Advanced: all information at a glance; intuitive; real-time graphs. Very easy to use and comfortable tools. Intuitive control panel equipped with Smartchuck: operations and rod change with one hand, effortlessly. - Mandrel opening: Ø from 1 to 13 mm - Stirring rod diameter for Pass-Through: up to 8.5mm Velp products guarantee you peace and security within your laboratory. - Safety button clearly visible from the front - IP54 protection - Integrated safety sensors CONTROL PANEL OF OHS DIGITAL MODELS A - 7 Segment Display LED B - Torque indicator bar C - Low speed LED (only OHS 200) D - Gear key (only OHS 200) – Timer key for other models E - High speed LED (only OHS 200) – Timer LED for other models F - Speed control knob G - Timer LED (for OHS 200) - Upper lock LED for other models H - Timer key (for OHS 200) – Lock key for all models I - Lower Lock LED J - Main switch K - Smart chuck

Digital Hot Plate Magnetic Stirrer AREC 10 Velp with VTF-cover
Digital Hot Plate Magnetic Stirrer AREC 10 Velp with VTF

AREC 10 Digital was designed for laboratory applications where a comfortable and large work surface  (more)is required, which here reaches 26x26 cm in size, the largest among the Velp series. The plate offers high resistance to acids, bases and solvents, while the technopolymer structure of the stirrer is designed to prevent accidental spills of liquids from reaching the electronic components, ensuring easy and quick cleaning. This translates into product safety and durability even in the most demanding laboratories; further protected by a 3-year warranty (subject to online registration). The heating uses the latest technologies available and ensures a uniform temperature across the entire plate and exceptional transfer efficiency. Same quality for agitation: SpeedServo™ technology and brushless motor offer precise and powerful agitation even when viscosity varies. In short, why we offer you AREC 10 Digital: - Easy to use and highly resistant to chemicals - Precise setting of temperature and agitation - Accepts volumes up to 25 liters / 30 kg - Possibility of precise thermoregulation of the fluid with Pt100/Pt1000 and VTF probes - Designed for durability and guaranteed for 3 years The powerful brushless motor of the AREC 10 Digital ensures stable and reliable stirring. The patented SpeedServo™ technology ensures constant speed even with variations in fluid viscosity. The always precise stirring speed, from chemical reactions to sample preparation, adjustable from 100 to 1500 rpm, it is ideal for any laboratory need. With a stirring capacity of up to 25 liters (H2O) (or 30 kg of liquid), the AREC 10 Digital stands out for its robustness and superior performance. Arec 10 reaches the remarkable temperature of +550°C in complete safety and control. Extremely precise, you can increase the temperature by +1.0°C. By connecting the external PT100 or PT1000 sensors you can directly thermoregulate the sample up to 350°C with an accuracy of ±1.0°C. Using VTF Digital instead you can control the temperature with a precision of ±0.5°C (up to a maximum of 300°C). In this regard, Arec 10 is available with different accessory packages. You will find all the combinations at the bottom.
