Barnstead MaxQ 2508 Dual-Action Orbital Reciprocating Shaker
The Barnstead MaxQ 2508 Dual-Action Orbital Reciprocating Shaker (model SHKA2508) is a versatile and accurate shaker for reproducible results in the lab. The MaxQ 2508 offers a speed range from 40 to 400 RPM with a triple eccentric drive and can be operated within incubators, warm rooms, environmental chambers, and refrigerators (operating range of 4° to 40°C with 20% to 80% humidity).The 2508 can be used for circular orbit motion or back-and-forth motion on a fixed 0.4 in orbit or stroke. Ideal for dissolution studies and staining of electrophoresis gels, growing bacteria, and chemical extractions. All of our equipment is fully tested to perform at factory specifications before being shipped.
The Barnstead MaxQ 2000 Digital Orbital Shaker includes:
- > Standard 13" x 11" Platform
- > Power Cord
- > Operator's Manual
- > Full 180 Day Parts and Labor Warranty

- Validate that the power supply and PCB deliver stable, correct voltage outputs across all necessary connections, ensuring reliable operation
- Thoroughly inspect the display for any dim, flickering, or dead pixels; replace affected elements to maintain full readability and operational clarity
- Test the full range of button functionality, confirming responsive, accurate input recognition across all settings
- Conduct a detailed inspection of bearings and bearing housing, identifying any worn or damaged bearings, and replace as needed to prevent operational disruption
- Examine the drive belt for signs of cracking, fraying, or material breakdown; replace as required to ensure sustained performance
- Measure and adjust motor drive belt tension to optimal specifications, securing reliable and efficient power transmission
- Verify accuracy of the onboard timer, confirming proper functionality and replacing if it deviates from expected performance
- Calibrate shaker rotation speed with a NIST-traceable tachometer, validating precision within specified operational limits
- Run the shaker continuously for an 8-12 hour testing period, closely observing the shaking platform for smooth, consistent motion, while monitoring for any error indicators such as knocking, skipping, or unusual vibrations
- Perform a comprehensive cosmetic inspection to confirm the device’s exterior meets aesthetic and quality standards, free from visible damage or wear
