Guardian 3000 Ohaus

THE TOP MODEL OF THE 5 SERIES Ideal for laboratories requiring precise sample temperature control an (more)d maximum reproducibility. The AREX 5 Digital magnetic stirrer is a beautiful instrument with a dual digital display for thermoregulating samples with an accuracy of ± 1.0 °C. Thanks to the VTF system then, it will be possible to achieve an accuracy of ± 0.5°C. Pt100 and Pt1000 probes are also available as an option. RESISTANCE, SAFETY AND PERFORMANCE The plate of the AREX 5 Digital Velp model is IP42 certified and is made of aluminum alloy coated with a ceramic layer, which guarantees protection from scratches and chemical agents, making it very resistant and easy to clean. It is therefore preferred in laboratories where acids, bases and solvents are used. Safety circuits and overtemperature protection guarantee complete protection for the operators. Two light indicators inform the user when the heating function is active. Even when the instrument is switched off, a safety message ('HOT') remains on the display until the plate temperature drops below 50°C. A further alarm will detect the presence of the probe. The plate structure and the insulating disc protect the internal parts and ensure high resistance to the most demanding laboratory environments and applications, for example when working with cold fluids (below 0°C). AREX 5 is designed to last over time and like most Velp products it is guaranteed for 3 years. THERMOREGULATION When a temperature probe is connected, it is possible to choose 2 different thermoregulation modes to satisfy all laboratory needs: - FAST: the set temperature is reached quickly - FINE: the set temperature is reached more slowly, minimizing the overshoot SHAKING AREX 5 is equipped with a powerful brushless motor for daily applications, being able to agitate up to 20 liters (H2O). It is also equipped with SpeedServo™ technology, which allows the speed to be kept constant even when the viscosity of the sample varies. The combination of the powerful brushless motor and the strong magnetic coupling ensure homogeneous stirring, even in the peripheral areas of the plate, guaranteeing a constant speed in all positions. DESIGN The compact, innovative and attractive design offers comfort and safety both during benchtop applications and in laboratory fume cupboards. The inclination of the front panel is designed to optimize the user experience and the bright LED display allows easy reading and constant monitoring of the temperature and stirring speed. APPLICATIONS AREX 5 is the ideal solution for temperature sensitive applications in many industrial, research and academic laboratory sectors. THE AREX DIGITAL PANEL: BEAUTIFUL AND SIMPLE TO USE By turning the left knob it will be possible to adjust the temperature up to 310°C, while with the right one it will be possible to set the stirring speed from 50 to 1500 rpm.

Benchmark TC 9639 Thermal Cycler w/ Multi-Format Block Benchmark’s TC9639 Thermal Cycler provides co (more)nsistent, reliable results for laboratories with medium to high throughput. From its large, touch-screen user interface to its unique, multi-format block, this cycler is loaded with features. The program wizard and 10 preinstalled programs make it easier than ever to get up and running. A large, full color touch screen serves as the operations center where all functions are accessed. From the “Home” screen, simply touch an icon to view the last run program, enter the program library, or use the program wizard to quickly enter a protocol. In addition, icons for favorite programs can be added for faster access. The program wizard guides users through quickly setting up a protocol in a single screen. Once entered, programs are shown graphically, and can be edited by simply touching the step that requires modification. Time and temperature increments can be built into programs as well as slower ramp rates. Storage capabilities are unlimited; programs can be stored in public folders, private (password protected) folders or on a flash drive. The full virtual keyboard allows for alphanumeric naming of programs and folders. The fully adjustable heated lid prevents condensation and evaporation of samples. Lid temperature can be programmed, and when the block temperature is below 35C, the lid automatically shuts off. Heating and cooling of the block are precisely and accurately controlled within exceptionally tight tolerances by a proprietary algorithm that simulates sample temperature. With the multi-format block, there is no need for the expense of multiple interchangeable blocks. The TC 9639 has the flexibility to accept 96 x 0.2ml tubes, a 96 well plate or 39 x 0.5ml tubes all in the same sample block. An in-situ adapter is available for use with slides. Additionally, the unit may be purchased with a 384 well sample block.
