Fisher Scientific Hot Plate Stirrer Cat # 11-800-49SH
The Fisher Scientific Isotemp Hotplate Stirrer Cat: 11-800-49SH was designed with function, reliability, and safety in mind, intended for general indoor laboratory procedures. The 7 x 7 inch ceramic top hot plate is easy to clean, resists acids and alkalis, and stays flat even at maximum temp for uniform heating. Its reflective white surface allows for easy visualization of contrasts within your samples, and the hot top indicator lights when the temperature of the surface is above 40°C & is no longer safe to touch. The Fisher Scientific Isotemp Hotplate Stirrer’s sturdy base is constructed of cast-aluminum, enhancing its stability on the benchtop. Temperature can be displayed in °C or °F, and easily set by controls on the front panel, along with the stirring speed. Both set and actual temp & stirring speed are displayed, during and after operation. The Fisher Scientific Isotemp Hotplate Stirrer automatically adjusts motor strength to accommodate aqueous, viscous, or semi solid solutions, making it ideal for all your laboratory needs.
Included with the Fisher Scientific Hot Plate Stirrer Cat # 11-800-49SH:

- Inspect the display for clarity and brightness, replacing any dim or dead pixels to ensure optimal performance.
- Examine external regulators for structural integrity and damage, replacing if necessary (if applicable).
- Assess the functionality of temperature, CO₂, and H₂O sensors, verifying accuracy and consistency (if applicable).
- Check all internal wiring for frays, tears, or breakages, addressing any compromised sections.
- Confirm software settings are properly configured to match the specifications of internal components.
- Inspect and clean the fan for efficient airflow, replacing if wear or malfunction is detected.
- Verify the condition of wheels and leveling mounts, ensuring stability and ease of movement.
- Inspect door gaskets and latches for sealing integrity, replacing if compromised to maintain proper enclosure.
- Calibrate temperature accuracy to 37°C using an NIST-traceable temperature probe for precision.
- Calibrate CO₂ levels to 5% using a Fyrite combustion test kit to verify environmental control (if applicable).
- Confirm temperature and CO₂ stability over a 24-hour period to ensure consistent conditions.
