Four-position fully automatic Soxhlet extractor with metal-bath heating for granulated lignin fiber tests in asphalt pavement fiber analysis.
Overview
This instrument is designed per JT/T 533-2020 "Fibers for Asphalt Pavement" Appendix M (granulated lignin fiber pelletizer content and rotational viscosity) and Appendix D (thermal removal of pelletizer for granulated lignin fiber in the oil-absorption test). It uses Soxhlet extraction with integrated metal-bath heating to perform extraction, rinsing and solvent recovery in one unit. The main cabinet holds four glass extractors, allowing four samples to be processed simultaneously; a separate industrial chiller on the right supplies circulating cooling water to the condensers. Heating temperature is adjustable according to solvent boiling point and ambient conditions; extraction time is programmable, after which the process ends and solvent is recovered automatically.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Microcomputer-controlled operation with digital display for direct readout
• Automatic test cycle with data storage and report generation
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Automatic Soxhlet Extractor (4-Position) comply with?
A1: The Automatic Soxhlet Extractor (4-Position) is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Automatic Soxhlet Extractor (4-Position) be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
