Introduction to Rotating and Elevating Double Jacketed Glass Reactor

1. Key Features & Innovations

The ZALFGR series stands out due to several engineering upgrades:

• Lifting & Rotation: Manual lifting for easy feeding and crystal removal; the kettle body rotates 0~120° for thorough cleaning.

• Advanced Sealing: Uses a flange connection sealing method (no vacuum grease required), providing superior sealing, higher vacuum levels, and eliminating the common issue of "stuck" joints.

• Bottom-Feeding Design: A blind-spot-free bottom-feeding design ensures complete mixing and reaction, simplifies cleaning, and prevents cross-contamination.

• Structural Stability: A parallel steel base and full-flange connectors enhance operational stability and can withstand positive pressure up to 0.03Mpa.

2. Complete System Components

The full system typically includes:

3. Main Components Detailed Description

A. Reactor Section

• Material: High borosilicate glass (GG17) with excellent chemical corrosion resistance.

• Design: 10L jacketed reactor with a 6-open kettle cover (ports for stirrer, constant pressure dropping funnel, reflux condenser, temperature sensor, solid/liquid feeding).

• Sealing: Kettle lid and body are sealed via handwheel lifting and squeezing (flange type, grease-free).

• Base & Mobility: Parallel steel base for stability, equipped with casters for easy movement; the entire system can move as one unit, allowing flexible spatial placement.

B. Overhead Stirring System

• Sealing: Double-seal stirring bearing ensures high system airtightness.

• Material Options: Glass, stainless steel, or PTFE-coated fluorine materials available.

• Stirring Paddle: Standard PTFE double-layer mixing paddle; other types of impellers can be easily swapped based on experimental needs.

C. Vacuum Unit

• Offers multiple pump options:

• Diaphragm vacuum pump

• Rotary vane-type oil-sealed vacuum pump

• Circulating water-type multi-purpose vacuum pump

D. Temperature Control & Intelligent Monitoring

• Standard: Digital display of stirring speed with variable frequency control for smooth, constant-speed operation.

• Optional Upgrade (ZN Intelligent System): Real-time display of temperature, acidity, viscosity (torque), and stirring speed; supports stage programming control, feeding pump speed/time control, and PC connectivity for remote data collection, recording, and curve plotting.

Summary: Core Strengths

This reactor series is ideal for pilot-scale R&D in pharmaceuticals, fine chemicals, and material science, where precision, cleanliness, and process automation are critical.
