Introduction
A vacuum distillation tester is an instrument used to perform the distillation tests of the petroleum products under the reduced pressure, for the measurement of the boiling range of the samples that decompose at the atmospheric pressure, and it is used in the petroleum, the petrochemical, the fuel, and the quality control industries. The vacuum distillation tester performs the distillation of the sample under the vacuum, following the standard test methods, such as the ASTM and the ISO standards, and it measures the temperatures at which the successive volumes of the distillate are collected at the reduced pressure, and it provides the distillation curve, which is corrected to the atmospheric pressure; the vacuum distillation tester consists of a distillation flask, a heating system, a vacuum system, a condenser, a receiving vessel, a temperature measurement system, and a control and a data analysis system, and it provides features such as the automated operation and the data management; the vacuum distillation tester is used for the testing of the heavy petroleum products, such as the fuel oils, the lubricants, and the crude oils, for the measurement of the boiling range, for the quality control, for the assessment of the volatility, and for many other applications, and it is an essential instrument for the petroleum testing. Vacuum distillation testers are used in the petroleum industry, in the petrochemical industry, in the laboratories, in the quality control, and for many other applications. With their vacuum distillation, vacuum distillation testers are essential for the heavy oil analysis.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The vacuum distillation tester is used in petroleum refineries, lubricant laboratories and third-party testing organizations to determine the distillation range of high-boiling products such as lubricating oils, waxes, bitumen fractions and residual fuels. It supports product specification verification, process optimization and quality control where atmospheric distillation would cause thermal decomposition of the sample before complete vaporization.
Q2: What standards does the instrument comply with?
A: The test method follows ASTM D1160 for distillation of petroleum products at reduced pressure, ISO 6615 for petroleum products distillation characteristics, and the corresponding GB/T 255 method. The instrument hardware complies with relevant laboratory electrical and pressure safety standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole tester is covered by a 12-month warranty. The vacuum pump, heating system, temperature sensor and controller are covered, while distillation flasks, seals, gaskets and vacuum oil are consumables excluded from warranty. Damage from improper vacuum operation or glassware breakage is also excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with vacuum distillation technique and petroleum test methods. We provide an operation manual and remote guidance. On-site or structured training can be arranged for first-time users to ensure correct assembly, vacuum control and safety procedures.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Temperature sensors should be calibrated against a reference thermometer every 6-12 months. Vacuum gauge verification is recommended annually. System suitability with a reference sample of known distillation range should be run periodically to confirm overall performance.
Q7: Are supporting consumables universal?
A: Distillation flasks, receivers, seals and vacuum pump oil are available from laboratory suppliers, though original glassware is recommended for dimensional compliance. Vacuum pump maintenance should follow the manufacturer schedule to maintain required vacuum level.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes vacuum range, maximum temperature, sample volume and automation level. Additional glassware sets, spare heaters and vacuum pump options can be ordered separately. Custom orders extend delivery lead-time and cost.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the instrument, glassware and accessories with an operation manual. Remote commissioning guidance is provided. On-site installation and training are not included for standard orders but can be arranged for laboratory setup projects.
Q10: What types of samples are compatible with this equipment?
A: The tester handles high-boiling petroleum products and heavy fractions within the method range. Samples containing water should be dehydrated before testing to avoid bumping. Highly corrosive or reactive samples can damage glassware and the vacuum system and require special handling or pretreatment.
