SZC-D Soxhlet Fat Analyzer

Product Introduction

The SZC-D Soxhlet Fat Analyzer is designed for determining crude fat content in food, feed, oils, and other applicable materials using the Soxhlet extraction principle and gravimetric analysis. It integrates sample soaking, solvent extraction, heating, cooling, and solvent recovery into a streamlined workflow.

Equipped with a fully enclosed electric heating system, digital temperature control, automatic timing, and automatic heating shutdown, the SZC-D supports the simultaneous testing of up to six samples. Its PTFE sealing structure and solvent recovery function help improve operational safety, reduce solvent consumption, and support repeatable laboratory analysis.

• Fully Enclosed Electric Heating: Uses an aluminum-alloy electric heating plate for controlled and uniform heating.

• Digital Temperature Control: Provides adjustable temperature settings and automatic temperature regulation.

• Automatic Solvent Recovery: Recovers solvents after extraction to reduce reagent consumption and operating costs.

• Integrated Extraction Workflow: Combines soaking, extraction, heating, cooling, and solvent recovery in one system.

• Automatic Timing and Shutdown: Supports preset timing from 0 to 9,999 minutes, followed by automatic heating shutdown.

• Safety Protection: Features a fully enclosed electrical system, non-contact circuit control, over-temperature protection, and an alarm function.

• PTFE Sealing: Uses PTFE sealing components to help maintain sealing performance during extraction.

•  Adjustable Operating Conditions: Allows temperature adjustment according to solvent properties and experimental requirements.

• Compact Laboratory Design: Integrates multiple extraction functions into a benchtop instrument.

Working Principle

The SZC-D operates according to the Soxhlet extraction principle combined with gravimetric determination. A prepared sample is exposed to a suitable solvent, which extracts the fat from the sample matrix. The extraction process involves heating the solvent, vaporization and condensation, solvent contact with the sample, and repeated extraction cycles.

After extraction, the solvent is recovered and the remaining extracted material is processed according to the applicable analytical method. Crude fat content is determined by weighing and calculating the extracted residue relative to the original sample mass.

The instrument's digital temperature controller regulates heating, while the timer and automatic shutdown function help standardize operating conditions. Solvent recovery helps reduce solvent waste and routine operating costs.

Technical Parameters

Specification note: The source introduction mentions a temperature range up to 200°C, while the technical parameters specify up to 280°C. The technical table follows the detailed parameter list; confirm the rated operating range with the manufacturer. The stated relative difference and parallel difference should also be verified against the applicable test method.

Frequently Asked Questions

1. What is the SZC-D Soxhlet Fat Analyzer used for?

It is used to determine crude fat content in suitable samples, including food, feed, oils, and other materials compatible with the selected extraction method.

2. How many samples can the SZC-D process at once?

The instrument can test up to six samples simultaneously.

3. What is the measurement range for crude fat content?

The supplied specifications state that it is suitable for crude fat contents of 0.5% and above. The applicable range depends on the sample type and analytical method.

4. Does the SZC-D automatically recover solvent?

Yes. It includes an automatic solvent recovery function designed to reduce solvent consumption and operating costs.

5. What is the temperature control range?

The detailed technical parameters specify an adjustable range from room temperature to 280°C, with a temperature control accuracy of ±0.3°C. The maximum operating temperature should be confirmed with the manufacturer because the introduction lists a different upper limit.

6. Does the instrument have automatic timing?

Yes. The timer can be set from 0 to 9,999 minutes, after which the instrument automatically stops heating.

7. What safety features are included?

The SZC-D features a fully enclosed electrical heating system, non-contact circuit control, over-temperature protection, automatic power disconnection, and an alarm function.

8. What is the solvent recovery performance?

The stated solvent recovery rate is at least 80%. The source also specifies a solvent return rate of at least 99% under conditions of 120 drops per minute and a cooling-water temperature of 30°C.

9. What power supply does the SZC-D require?

It operates on 220 V AC ±10% at 50–60 Hz, with a rated power of 500 W.

10. How does Soxhlet extraction determine crude fat content?

A suitable solvent extracts fat from the sample through repeated extraction cycles. After solvent removal, the extracted residue is weighed and used to calculate the crude fat content according to the selected analytical method.
