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.

This listing is for 1 of 2 Watson Marlow 520S Peristaltic Pump. The unit is in full working conditi (more)on and is ready for immidate realese. Peristaltic pumps are the simplest possible pump, with no valves, seals or glands to clog or corrode. The fluid contacts only the bore of a tube, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. Peristaltic pumps can operate dry without risk. Easy to install, simple to operate and inexpensive to maintain, peristaltic pumps are ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. Suitable for metering, dosing and dispensing applications.   520S drive offers manual control via a large-key membrane keypad: speed adjustment; run and stop; forward/reverse; "Max" key for rapid priming and purging.   Supply voltage/frequency: 100-120V/200-240V 50/60Hz Flow rates from 4 microliters/min up to 2.4 liter/min Precise 2,200:1 speed control range from 0.1 to 220 rpm in 0.1 rpm increments Large speed/flow display and easy to use tactile membrane keypad. Incorporates keypad lock Manual control and flow rate calibration MemoDose for accurate single shot dispensing
