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

Maximum Temperature Homogeneity The aluminum alloy plate ensures a formidable temperature homogeneit (more)y over the entire surface of the plate itself, up to 370°C. Fontal panel The control panel is extremely intuitive. By turning the left knob it is possible to adjust the temperature (up to 370°C), while with the right one you can act on the agitation (up to 1500rpm). Maximum Protection, IP 42 ARE magnetic stirrers guarantee a high level of safety and protection for the user, thanks also to the raised control panel and the special channel for conveying liquids (in case of spills). The control panel is easily accessible, away from heat sources that are dangerous for the operator and protected from any liquid leaks by means of a special conveyor channel. The particular geometry prevents accidental overflows of liquid being processed from entering the internal parts of the instrument. Low Profile, Attractive Design ARE offers an innovative low profile and a highly attractive design for greater comfort for the user. Even the inclination of the front panel has been carefully studied to facilitate its use. AluBlocks™, Greater Versatility AluBlocks™ allow you to perform different heating and stirring experiments with unprecedented flexibility, acting on different types and sizes of tubes. Being modular, they are ideal for creating a workstation that is always customized, capable of supporting tubes of different formats. Made entirely of aluminum, they can be easily placed on the round head heating stirrers for excellent heat transmission and temperature homogeneity. A huge leap forward in productivity, while also saving time, money and counter space.
