SHKE4000 Barnstead Bench Top, Incubated Shaker

The Thermo / Barnstead / Lab-Line MAX Q 4000 Series of Benchtop, Incubated and Refrigerated Shakers are available in either analog or digital control configurations:

• A-Class shakers: SHKA4000, SHKA4000-1CE, SHKA4000-5, SHKA4000-6CE, SHKA4000-7, SHKA4000-8CE: control temperature by a Proportional/Integral/Derivative microprocessor-based controller. Solid-state control maintains time and speed and is adjustable with rotary dials. Analog tachometer displays speed in RPM, verifying accuracy of speed setting. Refrigerated units feature environmentally safe CFC free insulation and coolant.
• E-Class shakers: SHKE4000, SHKE4000-1CE, SHKE4000-5, SHKE4000-6CE, SHKE4000-7, SHKE4000-8CE: control temperature, time and speed by a Proportional/Integral/Derivative (PID) microprocessor-based controller that is adjustable with membrane switches on a keypad in 1 rpm increments. Refrigerated units feature environmentally safe CFC free insulation and coolant. Flashing display indicates power interruption. Pressing any key will clear display. Non-volatile memory maintains speed and time set points in the event of a power interruption. Speed and time set points are automatically reactivated after power is restored.

Temperature range and accuracy follow. All units have a uniformity of ±0.5°C at 37°C in flask:

• Standard Temperature: SHKA4000, SHKA4000-1CE, SHKE4000, SHKE4000-1CE, 50°C above ambient to 60°C, ±0.1°C at 37°C in flask.
• High Temperature: SHKA4000-5, SHKA4000-6CE, SHKE4000-5, SHKE4000-6CE, 50°C above ambient to 80°C, ±0.1°C at 37°C in flask.
