Description

Technical Parameters

The Centrifuge Extractor for Determination perfectly addresses the challenges of traditional separatory funnels, including low separation efficiency, cumbersome operation, time-consuming operation, prone to emulsification, and significant organic solvent loss due to evaporation. It is an ideal tool for extraction, washing, and purification operations in modern laboratories, particularly in the chemical, pharmaceutical, environmental, and hydrometallurgical fields.

Core Principles

The core principles of the Centrifuge extraction test device are centrifugal sedimentation and countercurrent contact.

Mixing and mass transfer: Two immiscible liquids of different densities enter the device's high-speed rotating drum via an inlet pump or gravity. Within the drum, they are intensely mixed, creating a large contact surface area and enabling efficient transfer of solutes from one phase to the other.
Centrifugal separation: Under the powerful centrifugal force of the mixed liquids, the density difference between the two phases causes the heavy phase to be flung toward the outer periphery of the drum, while the light phase is concentrated toward the center.
Countercurrent outflow: Guided by the unique structure of the drum, the separated heavy and light phases flow through different channels and exit continuously and clearly from their respective outlets in countercurrent directions, achieving a continuous extraction and separation process.

Highlights and Advantages

High Efficiency and Speed: The separation process is completed in seconds to tens of seconds, significantly improving efficiency by several times compared to traditional static separation processes that take several hours.
Excellent Separation: The powerful centrifugal force effectively breaks up emulsions, achieving a thorough and clear separation of the two phases with high recovery rates.
Continuous Operation: The Automatic Bitumen Centrifuge Extractor enables continuous feeding and discharging, making it ideal for continuous exploration of process conditions and data collection.
Excellent Sealing: The fully enclosed system effectively prevents the leakage of toxic and volatile organic solvents, protecting the health of experimenters and the environment.
Low Material Inventory: The Centrifugal Scraper Film Evaporator maintains a low internal liquid holdup, requiring only small amounts of material for testing, saving expensive reagent costs.

Typical Applications

Pharmaceutical Industry: Extraction and purification of antibiotics, chiral drugs, and natural products.
Chemical and Metallurgical Industry: Specialty chemical refining, wastewater resource recovery, and enrichment of rare earth metals, copper, nickel, and other metals.
Environmental Protection and Nuclear Engineering: Treatment of phenolic, oily, and heavy metal-containing wastewater, and separation of radioactive elements.
Food Industry: Oil refining, flavor and fragrance extraction.

Selection and Usage Considerations

When selecting and using a Centrifuge extraction test device, consider the following:

Processing capacity: Select a model with an appropriate flow range based on experimental requirements.
Speed and centrifugal force: Higher speeds and centrifugal forces mean greater separation capacity, especially for systems with similar densities or easily emulsifiable materials.
Material compatibility: The material of the device's contact with the material must be resistant to the chemicals being processed.
Ease of use: Ensure the device is easy to disassemble, clean, and maintain. Features like touchscreen controls and parameter memory can enhance the user experience.
Safety: Ensure the device has the necessary safety certifications and protective features.
