Digital Display, Total Control of Operations DLS guides the user through an extremely bright and eas (more)y to read display. All the main parameters are constantly shown at a glance, including the set speed, the actual speed, the torque value and the timer. In fact, DLS is equipped with a programmable digital timer up to 999: 59 minutes with automatic shutdown, allowing autonomous operation. Vigorous agitation The powerful rod stirrers are able to process even the most demanding substances, ensuring a smooth start and vigorous stirring at maximum speed! DLS can reach speeds of 2000 rpm, making it ideal for volumes up to 25 liters and medium viscosities, with a maximum of 25,000 mPa*s. Convenient chuck and high security The intuitive spindle locking system is the simplest and most comfortable available on the market, and does not require any special tools, offering the possibility of using different rod models, for the most varied applications, with a maximum diameter of 10 mm. VELP Scientifica solutions are extremely intuitive and easy to use, being equipped with the most advanced features in terms of safety, including overload and overtemperature. All models operate according to IP 40. Longest possible longevity All our solutions have been carefully designed to offer a long life to the instrument, even in the most difficult operating conditions. The structure covers and protects the engine from any aggressive liquids and vapours, preventing internal corrosion phenomena. The robust motor guarantees continuous operation over the years, without additional costs for maintenance.
