Product Overview
An electric heating sleeve, also called a heating mantle, heating jacket, or heating sleeve, delivers uniform contact-based heat to round-bottom flasks in laboratories where open flames are prohibited. BKMAMLAB Labshark heating sleeves and magnetic-stirring heating sleeves are available in four flask-volume sizes: 250 mL, 500 mL, 1000 mL, and 2000 mL, suitable for spherical flasks, single-neck flasks, three-neck flasks, and standard reflux setups.
Key Features & Advantages
- Four flask-volume sizes: 250 mL, 500 mL, 1000 mL, and 2000 mL to match common round-bottom flask sizes.
- 304 stainless-steel shell with Teflon anti-corrosion treatment: Resists chemical corrosion from acids, bases, and organic solvents.
- Spherical heating element: Wraps the flask evenly for uniform heat distribution without hot spots.
- Digital PID temperature controller: Fuzzy-PID algorithm with ±1°C control accuracy; displays both set temperature (lower row) and measured temperature (upper row).
- Anti-dry-burning thermal protector: Automatically trips when temperature exceeds 60% of the rated range, preventing damage and fire hazards.
- Magnetic-stirring models available: Independent rotation-speed control for simultaneous heating and stirring.

Comparison & Competitive Advantages
Unlike Bunsen burners and open-flame heating that are prohibited in many laboratories handling flammable solvents, the BKMAMLAB Labshark heating sleeve provides flame-free, enclosed heating with uniform thermal contact. Compared to oil baths that are messy, pose burn hazards, and degrade over time, the heating sleeve delivers direct contact heat without a heat-transfer medium. The ±1°C PID control accuracy and anti-dry-burning protector provide superior safety and precision compared to basic analog heating mantles.
Applications
Ideal for organic-synthesis reflux, distillation, evaporation, Soxhlet extraction, constant-temperature reactions, and reagent heating. Suitable for laboratory research, bioengineering, pharmaceutical formulation, and scientific-research education environments.
Frequently Asked Questions
Q: What is a heating sleeve (heating mantle) and when should I use one?
A: A heating sleeve is an electric heating device that wraps around a round-bottom flask to provide uniform, contact-based heat. It is used in laboratories where open flames are prohibited, making it ideal for organic-synthesis reflux, distillation, evaporation, and Soxhlet extraction with flammable solvents.
Q: What flask sizes are available for the BKMAMLAB Labshark heating sleeve?
A: BKMAMLAB Labshark heating sleeves are available in four sizes: 250 mL, 500 mL, 1000 mL, and 2000 mL. They are compatible with spherical flasks, single-neck flasks, three-neck flasks, and standard reflux setups.
Q: Does the heating sleeve have over-temperature protection?
A: Yes, the heating sleeve is equipped with an anti-dry-burning thermal protector that automatically trips when the temperature exceeds 60% of the rated range, preventing damage to the instrument and potential fire hazards.
Q: Can the heating sleeve stir and heat simultaneously?
A: Yes, the magnetic-stirring heating sleeve models provide independent rotation-speed control, allowing simultaneous heating and stirring. The PTFE-coated stir bar is chemically resistant and suitable for most laboratory solvents.
