Multiposition magnetic stirrer MULTISTIRRER 6 digital Velp-cover
Multiposition magnetic stirrer MULTISTIRRER 6 digital Velp

Multiposition magnetic stirrer MULTISTIRRER 6 digital Velp The MULTISTIRRER Digital series is one of (more) a kind and represents the state of the art of multi-position stirrers, being equipped with both a digital display, in order to be able to precisely set the stirring speed, and a timer. The Timer: used as a countdown with consequent automatic shutdown or for an inversion of the rotation, automatically and based on the time interval pre-set by the user. The display: digital, which allows a precise setting of the stirring speed, reaching the speed of 1500 rpm with 10 rpm steps. SpeedServo™ system: ensures a constant speed even when the viscosity varies (counter-reaction). The worktop: in stainless steel to ensure unparalleled resistance and thorough cleaning. The MULTISTIRRER Digital remain cold even after several days of operation, a highly appreciated feature in microbiology and biochemistry. Samples can also be thermostated by combining the stirrer with a recirculating water bath. ROBUST AND PRACTICAL - The control panel is protected from liquid spills - Heavy duty steel construction with epoxy coating - Stainless steel cover - Very low height - ergonomic - Lightweight, easy to move - Designed for maximum durability and backed by a 3 year warranty THE ADVANTAGES OF THE VELP MICROSTIRRER - Clear surface for viewing particles and color changes - Intermittent mode schedules to suit your workflows - It doesn't get hot, even after days of continuous use - Can thermostat samples using a recirculating water bath - Ideal for microtitration, microbiology and biochemistry - Soft start but quick achievement of the set speed - High power magneto 'PCM' driven by single phase motor for continuous operation - Timer from 1 to 900 minutes; continuously - Rotation reversal: 5 to 900 seconds

Complete system for rod stirrer OHS 60 Digital VELP-cover
Complete system for rod stirrer OHS 60 Digital VELP

Complete system with OHS 60 Digital, A00000366 Universal H-Stand, A00001307 Stainless steel helix st (more)irring rod, A00001301 Double clamp. OHS are designed to ensure the highest safety standards. The resistant sealed case and the IP 54 degree 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

Magnetic stirrer AM4 Digital Velp

AM4 Digital is the solution for laboratories that need precise control of sample temperature and max (more)imum reproducibility. Among its qualitative features we can find the possibility of connecting the Pt100, Pt1000 probes and the VTF digital thermoregulator, for accurate and direct control of the sample temperature. The CerAlTop™ plate, in aluminum alloy covered with a ceramic layer, guarantees a homogeneous and fast heat transfer over the entire surface, as well as high resistance to chemical agents and scratches. Designed to last and give you the comfort you need in the laboratory, the AM 4 Digital Multi-Position Magnetic Stirrer is covered by a 3-year warranty (online product registration required). In short: - Ceramic coated aluminum alloy - Electronic speed regulation up to 1500 rpm. - Stirring volume (H2O) up to 20 liters per position. - Temperature up to 310°C. - Connections for PT100, PT1000 and VTF 1 - Aluminum alloy plate with ceramic coating  2 - Main switch 3 - Speed ​​control knob 4 - Temperature control knob 5 - Visualization A - Probe LED B - Temperature setpoint LED The powerful brushless motor ensures stable and reliable stirring. The patented SpeedServo™ technology ensures constant speed even with variations in fluid viscosity. The consistently precise stirring speed, from chemical reactions to sample preparation, is adjustable from 50 to 1500 rpm for volumes up to 20 liters (H2O). The LED displays will always allow you to easily read the values, from any angle. For maximum precision, by connecting the external PT100 or PT1000 sensors you can directly thermoregulate the sample 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, various accessory packages are available. You will find all the combinations at the bottom. Safety during heating: - 'Hot surface' alarm when temperature exceeds 50°C, even when inactive. - Overtemperature alarm The new spherical caps replace the oil baths and heating mantles. They adapt perfectly to both the 135 mm plate and the shape of the tubes, ensuring rapid heat transfer. To improve protection and reduce heat loss, VELP has designed new PTFE covers. The MultiAlublock™ and new MonoAlublock™ solutions are ideal for carrying out multiple stirring and heating analyzes in laboratories with limited space and time.
