MJ Research PTC-200 Thermal Cycler
Thermal Accuracy
± 0.3C of programmed target
- Accommodates a variety of formats including 60, 96, 384 well blocks and dual 48 well blocks
- Precisely delivers electronically controlled temperature for all applications
- Achieves rapid stabilization at set points within 30 seconds
- Maintains minimal temperature differences between wells, confined to ±0.4°C within 30 seconds after reaching 90°C
- Offers extensive control over virtually every thermal parameter
- Allows for continuous-temperature incubations for uninterrupted experiments
The MJ Research PTC-200 Thermal Cycler utilizes interchangeable sample blocks and heat pump assemblies, which allow the user to change format easily between runs while retaining NIST-traceable accuracy. This PTC-200 comes with a 96-well alpha block and can accommodate 60 well blocks, 384 well blocks, dual 48 well blocks, and many others, including specialty blocks like the insitu. The precise Peltier effect heat pumps deliver the full temperature range of 0 to 100C electronically, all in a compact, small-footprint instrument. The MJ Research PTC-200 offers speedy ramping rates of up to 3.0/sec in models that hold 0.2ml tubes or V-well plates. It also features unparalleled temperature homogeneity of 0.4C within 30 seconds of arrival at 60C for all standard models. The PTC-200 has a large memory and amiable software that allows control over virtually every thermal parameter.
The MJ Research PTC-200 is in excellent condition and will be fully tested to perform at factory specifications before being shipped.
The MJ Research PTC-200 Thermal Cycler includes:
- > 96-Well Alpha Block
- > NIST Traceable Calibration Certificate
- > Power Cord
- > Operator's Manual
- > Full 180 Day Parts and Labor Warranty

MJ Research PTC-200 Thermal Cycler
- Validate that the power supply and PCB consistently deliver accurate, stable voltages across all circuits and connections, confirming operational reliability
- Thoroughly inspect the display for any dim, flickering, or dead pixels, replacing compromised segments to ensure clear visibility and precise data display
- Verify complete functionality and responsiveness of all buttons and knobs, confirming accurate and reliable input across all controls
- Ensure the machine completes all internal diagnostic checks with zero errors, indicating system readiness and functional integrity
- Confirm the machine accurately identifies attached blocks (96-well, dual 48, etc.), with seamless recognition across different configurations
- Conduct a detailed inspection of internal wiring and all electrical connections, checking for any signs of breaks, disconnections, or tears; replace or repair any underperforming components
- Examine the connector between the block and base for bent or broken pins, replacing as needed to maintain secure, reliable connections
- Calibrate well temperatures with a NIST-traceable thermometer, verifying accuracy and uniformity across all wells to meet specification standards
- Perform a comprehensive cosmetic inspection, ensuring all exterior surfaces and components are free of damage, wear, or defects, maintaining aesthetic and professional quality
