±1°C at 20°C to 100°C
- Corrosion-resistant PTFE coating for durability.
- Includes an insulated outer wall and two overtemperature shutoffs for added safety.
- Equipped with a digital LED display for real-time temperature monitoring and setpoint adjustments.
- Designed for use with R-200 and R-205 Rotavapor Systems.
- Analog for user-friendly operation.
- Maintains ±1°C accuracy at 20°C to 100°C and ±2°C at 100°C to 180°C.
The Buchi B-490 Heating Bath can accommodate evaporating
flasks ranging in size from 50 to 3000mL, with an overall holding capacity of 5L.
This heating bath can be adjusted from 20° to 180°C and has a temperature
accuracy of + 1ºC, making it suitable for high/low boiling solvents. The Buchi
B-490’s aluminum heating pan features a corrosion-resistant PTFE coating and,
for added safety, an insulated outer wall and two overtemperature shutoffs. The
waterbath features a digital LED display, which shows real-time temperature and
setpoint. (The B-490 is for use with and included in evaporating systems
R-200 and R-205.)
All of our equipment is fully tested to perform at factory
specifications before being shipped.
The Buchi B-490 Heating Bath includes:
- > Power Cord
- > Full 180 Day Parts and Labor Warranty

Marshall Scientific Buchi B490 Heating Bath
- Confirm power supply and PCB are outputting stable, correct voltages across all essential circuits to ensure reliable operation
- Inspect the display for any dim, flickering, or dead pixels, replacing any compromised sections to maintain full clarity and accurate readouts
- Verify that all buttons, knobs, and switches are functioning properly, providing precise and responsive control across all settings
- Conduct a thorough inspection of the water reservoir for any holes, rust, or other structural damage that may impact its integrity
- Fill the reservoir with water, checking closely for any external or internal leaks that could affect performance
- Examine the lid for any signs of wear or damage, replacing hinges and handles if necessary to ensure a secure and proper seal
- Inspect for any internal leaks originating from the water reservoir, confirming the unit’s internal plumbing integrity
- Conduct a comprehensive inspection of internal wiring for any breakages, tears, or wear; replace any underperforming or damaged components to maintain safe operation
- Examine internal insulation for signs of burns, breaks, or deterioration, replacing as needed to ensure thermal efficiency and safety
- Confirm that all feet are intact and that the bath sits level and balanced on a flat surface to prevent movement or instability
- Calibrate both temperature accuracy and uniformity using a NIST-traceable temperature probe, verifying compliance with specification standards
- Perform a detailed cosmetic inspection to confirm that all external surfaces and finishes meet aesthetic and quality standards
