Laboratory glass reactors are categorized into double-layer and single-layer models based on specific requirements. They feature a mobile stainless steel frame structure and a five-port reactor lid equipped with glassware for reflux, liquid addition, and temperature monitoring. They utilize alloy steel mechanical seals and PTFE connections to maintain high-precision sealing during operation. A Pt100 sensor probe ensures high temperature measurement accuracy with minimal error, effectively enhancing work efficiency.
These reactors employ brushless motors that provide high torque and noise-free operation. They feature dual PTFE stirring paddles suitable for mixing liquids ranging from low to high viscosity, as well as a PTFE discharge valve with a movable interface for rapid material discharge.
The entire process—from initial feeding and reaction to final discharge—can be executed with a high degree of automation according to preset parameters. Critical variables such as temperature, pressure, mechanical factors (stirring, aeration, etc.), and reactant/product concentrations are strictly controlled throughout the reaction.
Applications: Laboratory glass reactors are used in chemistry, fine chemicals, biopharmaceuticals, and the synthesis of new materials for experiments, pilot-scale testing, and production. They can be integrated into systems with peripheral equipment such as circulating vacuum pumps, diaphragm vacuum pumps, low-temperature circulating (vacuum) pumps, circulating coolers, constant-temperature circulators, low-temperature coolant circulating pumps, and sealed heating/cooling circulation units.
Maintenance Guidelines:
1. Carefully inspect the instrument before use; check for damage to the glass vessels and ensure all interfaces fit correctly. Handle with care.
2. Wipe all interfaces with a soft cloth (or paper towel) and apply a small amount of vacuum grease.
3. Do not overtighten the interfaces; loosen and adjust them periodically to prevent the connectors from seizing due to prolonged tight fastening.
4. Turn on the power switch first, then gradually increase the operating speed. When shutting down, bring the machine to a complete stop before turning off the switch.
5. Do not overtighten the PTFE valves/switches, as this can easily damage the glass.
6. After each use, wipe the machine's surface with a soft cloth to remove any oil, stains, or solvent residues, ensuring the equipment remains clean.
7. Loosen the PTFE valves after shutting down the machine; leaving them tightened for extended periods can cause the PTFE pistons to deform.
8. Clean the sealing rings regularly: remove the ring, check the shaft for accumulated dirt, wipe it clean with a soft cloth, apply a small amount of vacuum grease, and reinstall it to ensure smooth contact between the shaft and the seal.
9. Keep the electrical components away from water and moisture at all times.
10. Use only genuine manufacturer parts; using unauthorized parts can cause catastrophic damage to the machine.
11. Always disconnect the power and water supplies before performing any repairs or inspections on the glass reactor.
Laboratory glass reactors are available in stainless steel and carbon steel versions. They feature a jacketed design and inner vessel built for atmospheric pressure operation; the structure is rational and durable, offering high-temperature resistance, corrosion resistance, and ease of use. They are widely used in industries such as petroleum, chemicals, rubber, food processing, and scientific research to facilitate processes like decomposition, polymerization, and condensation, as well as the synthesis of organic dyes, intermediates, and other chemical products.
