Constant Temperature Electric Heating Vacuum Mixer

Product Overview

This constant temperature electric heating vacuum mixer is designed for processing viscous gels, slurries, pastes, and other materials that require controlled mixing without entrained air. Vacuum operation suppresses bubble formation during agitation, while integrated electric heating allows the working temperature to be set from 50°C to 150°C. The combination helps improve material flow by reducing viscosity during processing.

The equipment is suitable for pharmaceuticals, adhesives, fragrances, cosmetics, coatings, pigments, additives, and other viscous glue-like materials. It is also applicable to research and production activities in scientific laboratories, medicine, fine chemicals, electronics, and new energy. A 50 ml to 1000 ml mixing capacity supports small-batch development, formulation trials, and process evaluation.

Built for direct process observation and dependable operation, the unit uses a transparent injection-molded polycarbonate vacuum vessel that is lightweight and resistant to impact. Reliable sealing, adjustable gas flow, and continuously observable vacuum status support controlled operation when material behavior must be monitored closely.

Key Features

• Vacuum Mixing Without Bubble Formation: Mixing under vacuum prevents bubbles from being generated in the processed material, supporting more uniform viscous formulations and cleaner laboratory results.

• Integrated Constant Temperature Heating: Electric heating provides a selectable working temperature from 50°C to 150°C, helping improve material viscosity and maintain a controlled processing condition.

• Transparent Polycarbonate Vessel: The injection-molded polycarbonate vessel is lightweight, impact resistant, and able to withstand substantial changes in vacuum conditions. Its transparency allows operators to observe the material and mixing state directly.

• Adjustable Mixing Speed: The 90 W motor provides an adjustable speed range of 40 to 466.6 rpm, allowing the operator to adapt agitation to different viscosities, batch sizes, and formulation requirements.

• Useful Torque Across the Speed Range: The drive delivers 21.3 kg.cm of torque at 333 rpm on the higher-speed side and 6.9 kg.cm at 25 rpm on the lower-speed side, supporting controlled agitation across the operating range.

• Fine Vacuum and Gas Adjustment: A dedicated precision needle valve enables fine adjustment of both incoming and extracted gas. This helps prevent sudden airflow from disturbing or blowing away material during processing.

• Reliable Sealing System: A high-quality silicone rubber ring seals the upper and lower vessel sections without requiring sealing grease. The rotating seal between the vessel and mixing shaft is also designed for reliable vacuum retention.

• Continuous Vacuum Monitoring: A vacuum gauge mounted on the side of the vessel allows the vacuum condition to be checked at any time during operation, giving operators direct process visibility.

• Fast-Change Pneumatic Connections: The needle valve and tubing use quick-change fittings, while imported soft nylon tubing supports convenient connection and routine handling.

• Practical Laboratory Handling: Material loading and unloading are convenient, and installation is straightforward, helping reduce setup time during repeated formulation and research work.

Why Choose This Product

• Controlled Processing for Viscous Materials: Vacuum mixing, adjustable speed, and temperature-assisted viscosity control are integrated into one laboratory system, reducing the need for separate process stages.

• Direct Observation During Operation: The transparent polycarbonate vessel allows operators to inspect the material and mixing condition without relying solely on end-point evaluation.

• Robust Vessel and Sealing Design: Impact-resistant polycarbonate construction, a silicone rubber sealing ring, and a reliable rotating shaft seal support stable vacuum operation during repeated laboratory use.

• Fine Operating Adjustment: The precision needle valve supports gradual gas-flow adjustment, while the adjustable motor speed and freely settable heating temperature provide practical control for different formulations.

• Efficient Small-Batch Development: A 50 ml to 1000 ml capacity is well suited to research, formulation screening, and process development where material quantities must remain controlled.
