Vacuum Distillation Tester LDT-T2018

Introduction

Vacuum Distillation Tester is a benchtop vacuum distillation tester that is ideal for the purification and concentration of natural products as well as complex and thermally sensitive molecules like vitamins and polyunsaturated fatty acids. In contrast to conventional distillation, which requires a few hours of heating, this technique has a relatively short heating time. The maximum temperature of the evaporation tube system can reach 200 ºC, the maximum temperature within the jacket can reach 300 ºC

This petroleum testing is designed to meet the rigorous requirements of modern laboratory operations, ensuring high precision, reliability, and ease of use for various experimental applications.

Applications

Vacuum distillation tester can be widely used in food, fine chemicals, electronic materials, plastic engineering, and polymer (such as polyols, fatty acids, polyphenols, polyurethanes, epoxy resins, milk fat, , flavors and fragrances, heavy oil, and paraffin oil) purification etc.

FAQs

1. How does the Vacuum Distillation Tester form a thin film, and why is it important for distillation?

Vacuum Distillation Tester uses a rotating scraper or roller inside the evaporation tube to spread the sample into a thin, even film along the inner wall. This thin film increases the surface area for heat exchange, allowing faster and more efficient evaporation at lower temperatures. It also minimizes the residence time of the sample in the heated zone, reducing the risk of thermal degradation. The self-cleaning action of the film-forming system ensures consistent performance and prevents fouling or buildup during extended operation.

2. Can the Vacuum Distillation Tester operate continuously or is it limited to batch use?

The Vacuum Distillation Tester is primarily designed for batch operation, but it supports semi-continuous processes with optional accessories like a metering pump for controlled feed. This allows users to extend operating times and improve overall efficiency for larger volumes. The robust design, high vacuum performance, and efficient heat transfer make it capable of maintaining stable operation over long durations. It's particularly useful when scaling up small-batch distillations to pilot-level production.

3. Is the Vacuum Distillation Tester suitable for processing high-viscosity samples or thick materials?

It Vacuum Distillation Tester is designed to handle viscous and sticky materials efficiently due to its film-forming wiper or scraper mechanism. The rotating wiper ensures that even dense samples are spread evenly as a thin film, enabling uniform heat exposure and effective evaporation. The system prevents sample buildup or blockage, which can occur in conventional distillers when processing thick substances. It is especially useful for distilling oils, resins, or polymers that require high-temperature, low-pressure handling.

4. What troubleshooting steps can be taken if vacuum levels are not reaching the desired setpoint in Vacuum Distillation Tester ?

Vacuum Distillation Tester may not reach the desired vacuum level if there are leaks in glass joints or seals, so these should be the first points of inspection. It’s also important to verify the vacuum pump’s condition and check whether the cold trap is full or blocked. In some cases, the sample may be releasing non-condensable gases that affect vacuum stability. Performing routine maintenance on O-rings, pump oil, and gaskets can prevent such issues. If the vacuum still doesn’t stabilize, isolating sections of the system and performing leak tests can help locate the fault.

5. What safety features are included in the Vacuum Distillation Tester ?

Vacuum Distillation Tester includes essential safety features such as over-temperature protection, vacuum safety interlocks, and thermal insulation around critical heating zones. The sealed all-glass construction helps prevent contamination or leakage, especially when dealing with volatile or hazardous chemicals. Additional options like explosion-proof configurations and -based control systems provide enhanced operational security in demanding environments. These built-in protections ensure safe and reliable usage in both laboratory and industrial settings. The design prioritizes user safety without compromising on performance or flexibility.
