Detailed Product Description
The StemAids Heating Block for Magnetic Stirrer for Flask is designed to improve heating efficiency and temperature uniformity during flask-based laboratory procedures. The block surrounds the round-bottom flask and helps transfer heat across the curved vessel surface more evenly than direct hotplate contact.
This accessory is useful when a laboratory procedure requires both heating and stirring. A compatible magnetic stirrer rotates the magnetic stir bar inside the flask, while the heating block supports controlled warming of the sample. This combination is suitable for chemical reactions, reflux setups, dissolution work, extraction procedures and long-duration sample heating.
The flask heating block can help reduce the need for oil bath handling in selected applications. It avoids oil spills, reduces cleaning effort and provides a cleaner heating setup when used with compatible laboratory instruments.
This product is recommended for laboratories that use round-bottom flasks for routine heating, synthesis, research, teaching demonstrations and analytical preparation. The correct block size must always be selected according to the flask capacity.
Applications
- Heating round-bottom flasks during magnetic stirring
- Organic synthesis and reaction heating
- Reflux experiments
- Evaporation and concentration work
- Heat-assisted extraction
- Reagent preparation and solution warming
- Sample preparation in QC laboratories
- Pharmaceutical and chemical laboratory workflows
- Research and development procedures
- Educational chemistry practicals and demonstrations
How to Use StemAids Heating Block for Magnetic Stirrer for Flask
- Select the correct block size: Choose a heating block that matches the flask size, such as 100 mL, 250 mL, 500 mL or 1000 mL.
- Check compatibility: Confirm that the heating block is suitable for the magnetic stirrer or heating magnetic stirrer system being used.
- Place the stirrer safely: Keep the compatible stirrer system on a clean, dry, flat and heat-resistant laboratory bench.
- Install the heating block: Place or connect the heating block as per the supplied equipment manual.
- Prepare the flask: Add the sample liquid and a suitable PTFE-coated magnetic stir bar into the round-bottom flask.
- Position the flask: Place the flask carefully into the heating block so that it sits securely and remains stable.
- Use support accessories: Secure the flask with clamps, boss head and stand rod where required, especially for reflux or long-duration heating.
- Insert temperature probe: If supported, place the PT1000 or compatible temperature sensor into the sample without touching the stir bar.
- Start stirring: Begin at low speed and gradually increase rpm until smooth mixing is achieved.
- Set heating temperature: Adjust the temperature according to the sample requirement and safe operating limit.
- Monitor operation: Observe temperature, stirring stability, liquid level and glassware position during heating.
- Switch off after use: Turn off heating and stirring before removing the flask.
- Allow cooling: Let the heating block cool completely before touching, cleaning or storing it.
Safety Instructions
- Use only with compatible magnetic stirrer or heating controller systems.
- Select the correct heating block size for the flask capacity.
- Do not touch the heating block during or immediately after operation.
- Always use heat-resistant round-bottom flasks.
- Do not heat sealed flasks or closed vessels.
- Use clamps and support stands for stable flask positioning.
- Keep flammable materials away from the heating area.
