A heating mantle 5000ml, is a laboratory apparatus used for gentle and even heating of round-bottomed flasks or other laboratory vessels up to a specified volume, in this case, up to 5000 milliliters (ml). It consists of a flexible, heat-resistant fabric or silicone sheath that wraps around the exterior of the vessel. Inside this sheath, there are heating elements, typically electric wires or coils, that generate heat when energized.
The 5000ml heating cover is suitable for experimental and production scenarios requiring high capacity and uniform heating, especially in the organic synthesis, material preparation, pharmaceutical and food industries. You need to configure the parameters based on your requirements (temperature range, temperature control accuracy, and security).
heating mantle 5000ml
The 5000ml capacity refers to the maximum size of the vessel that can be safely and effectively heated by the mantle. It ensures that the heating elements are positioned and powered appropriately to maintain an even temperature throughout the entire volume of the vessel, up to its 5000ml capacity.
The use of a heating mantle can potentially lead to the bursting or cracking of glass laboratory ware, though this outcome is not inevitable and can be mitigated by proper precautions and handling. A heating mantle is a device designed to uniformly heat flasks, beakers, or other round-bottomed glassware, often used in chemical reactions requiring gentle and controlled heating.

heating mantle 5000ml provides an ideal thermal environment for large-scale crystallization operations through precise temperature control and uniform heating. Its core advantage is that it is suitable for large-capacity containers (such as 5L crystallization reactors), which can effectively promote solution supersaturation control, crystal growth and purification, and significantly improve crystallization efficiency and product quality. The following three dimensions are explained from the process principle, application advantages, and operation points:
Example: When preparing paraxylene isomers, controlling the cooling rate (such as 0.5-1 degree /min) can obtain crystals with a particle size of 50-100μm.
Data: In the crystallization of bisphenol A, the purity of melt crystallization method can reach 99.9%, which is better than that of traditional distillation method (99.5%).
The high-capacity design supports multi-stage crystallization operations, progressively enriching the target product through repeated solution-crystallization cycles.
Case: When purifying naphthalene from ethylene tar, three melting crystallization can increase the purity of naphthalene from 5% to 93%, and the yield is over 40%.
Energy-saving and efficient
The melting crystallization operation temperature is lower than that of rectification (such as bisphenol A crystallization temperature is only 150-160 degree ), the latent heat of crystallization is much less than the latent heat of vaporization, and the energy consumption is reduced by more than 30%.
Comparison: The energy consumption of the traditional distillation method is about 1200kJ/kg, and the melt crystallization method only needs 400kJ/kg.
Configuration: Temperature control accuracy ±1 degree , mixing speed 0-1000rpm adjustable.
Heating stage: heating at the rate of 5 degree /min to 5-10 degree above the boiling point of the solvent to ensure that the solute is completely dissolved.
Crystallization stage: Cooling at the rate of 0.5-2 degree /min, maintaining susaturation in the metastable region (△C=0.1-0.5g/100g solvent).
Speed: 300rpm at the beginning of crystallization promotes solute dispersion, and 50rpm at the later stage reduces crystal fragmentation.
Impeller design: axial flow mixing impeller is used to ensure that the temperature difference between the upper and lower layers of the solution is less than 2 degree .
Heating rate: 0.1-0.3 degree /min to avoid crystal melting too fast resulting in entrainment of mother liquor.
Sweating time: adjusted according to the thickness of the crystal layer (such as 4-6 hours for 10mm crystal layer).
Effect: Crystal purity can be increased by 2-3 orders of magnitude after sweating.
