Incubating orbital shaker, Professional 3500

Supplier: VWR Collection
Designed for a variety of shaking applications such as cell cultures, solubility studies, bacterial suspensions and general mixing. Large capacity platform holds up to 15,9 kg. Variable speed, microprocessor control provides consistent, uniform mixing action. Ramping feature slowly increases speed to the set point for added safety. The Accu-drive shaking system delivers exceptional speed control, accuracy, safety and durability. System continuously monitors shaking speed and will maintain the set point even under changing loads. Displayed speed is accurate to 1% of set speed (when speed is above 100 min-1).

  • Three independent LED displays show speed, temperature and time
  • Integral timer, 1 s to 160 h, shows elapsed time or counts down, automatic switch off and audible alarm when program is complete
  • Microprocessor PID temperature controller maintains precise temperature from ambient +5 to 65 °C, adjustable in 1 °C increments and recalls last set points, even when unit has been shut off. Will also restart if power is interrupted
  • Opti-Flow forced ventilation system and triple-eccentric drive with brushless motor
  • Polycarbonate lid enables samples to be viewed, without altering internal temperature. When lid is opened, automatic shut off circuit will stop shaker platform to protect operator

Built-in load sensor can detect an unbalanced condition and will automatically reduce min-1 to a safe speed to prevent spills and protect samples. Powerful triple eccentric drive and brushless motor is designed for continuous duty and is able to handle heavy loads. Spill resistant design protects internal components from accidental spills and leaks. Removable tray design allows chamber to be cleaned easily. Opti-Flow forced ventilation system uses twin induction fans and air deflectors to deliver exceptional temperature uniformity and stability. Over-temperature sensor will shut down unit and activate audible and visual alarms if temperature limit is exceeded. Temperature calibration mode allows user to calibrate unit to an external temperature device and RS232 serial port provides two-way communication for data logging and unit control.

Accessories information: Shaker accommodates 60×10, 25×25, 13×50, 10×125, 9(8)×250, 7(5)×500, 4(2)×1000 ml flasks using stainless steel (PVC) flask clamps and 5×500 or 2×1000 ml media bottles.
