Introduction
A petroleum Bloom viscosity tester is an instrument used to measure the viscosity of the petroleum products by the Bloom method or the related efflux methods, and it is used in the petroleum, the lubricant, the fuel, and the quality control industries. The viscosity is a measure of the resistance of the fluid to the flow, and it is an important property of the lubricants and the fuels, and the Bloom viscosity tester measures the viscosity by the measurement of the time for a specified volume of the sample to flow through a calibrated orifice or a capillary under the controlled conditions, following the standard test methods, such as the ASTM standards, and it provides the viscosity, expressed in the units, such as the centistokes; the petroleum Bloom viscosity tester consists of a viscometer or the flow cup, a temperature control system, a timing device, and the accessories, and it provides features such as the temperature control and the digital timing; the petroleum Bloom viscosity tester is used for the measurement of the viscosity of the lubricating oils, the fuels, and the other petroleum products, for the quality control, for the assessment of the flow properties, for the product development, and for many other applications, and it is an essential instrument for the viscosity testing. Petroleum Bloom viscosity testers are used in the petroleum industry, in the lubricant industry, in the fuel industry, in the laboratories, and for many other applications. With their viscosity measurement, petroleum Bloom viscosity testers are essential for the oil quality control.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The petroleum Bloom viscosity tester is used in pharmaceutical, cosmetic, food and petroleum laboratories to measure the viscosity of gelatin, petroleum jelly, ointments and other viscous materials using the Bloom viscometer method. It supports quality control of gelatin for pharmaceutical capsule and food applications, petroleum jelly consistency evaluation, and cosmetic product formulation. The Bloom viscosity measurement provides a standardized assessment of material flow properties, which is critical for ensuring consistent product texture, processing behavior and end-use performance in industries where viscosity directly affects product quality and manufacturing processability.
Q2: What standards does the instrument comply with?
A: The test method follows ISO 9665 for gelatin Bloom value, ASTM standards for viscosity measurement, and relevant GB/T standards for gelatin and petroleum jelly testing. The bath complies with relevant laboratory electrical safety standards. Viscometer tube dimensions should follow the standard specification.
Q3: What is the warranty period for the whole machine and key components?
A: The bath and controller are covered by a 12-month warranty. Viscometer tubes, thermometers and seals are consumables excluded from warranty. Damage from improper tube handling, overheating or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with viscosity measurement and sample preparation. We provide an operation manual and remote guidance. Proper sample preparation, temperature equilibration and tube reading technique are important for accurate results.
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: Bath temperature calibration against a reference thermometer is recommended every 6-12 months. Viscometer tube constants should be verified periodically with certified viscosity standards. Full method verification with a reference material is recommended for accredited laboratories.
Q7: Are supporting consumables universal?
A: Viscometer tubes and thermometers are available from laboratory suppliers, though dimensions should match the standard method. Long-term consumable cost is low, with tube replacement being the main recurring item.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes bath capacity, temperature range and viscometer tube set. Additional tubes and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the bath, viscometer tubes and accessories with an operation manual. Remote commissioning guidance is provided. On-site service is not included for standard orders.
Q10: What types of samples are compatible with this equipment?
A: The tester handles gelatin, petroleum jelly and viscous materials within the method viscosity range and temperature specification. Samples must be properly prepared and degassed to avoid bubbles affecting measurement. Highly volatile or temperature-sensitive materials may require special handling. Users should follow the standard method for sample preparation, test temperature and reading procedure.
