KFDO-11 Automatic Karl Fischer Drying Oven
Product Introduction
The KFDO-11 Automatic Karl Fischer Drying Oven (Karl Fischer Sample Heating Oven) is a professional sample preparation device designed for Karl Fischer moisture analysis. It is mainly used for moisture determination of insoluble solid samples, granular materials, sheet materials, and samples that react with Karl Fischer reagents.
The KFDO-11 adopts a circularly distributed constant-temperature heating station design, which minimizes temperature differences between sample positions and improves measurement stability and repeatability.
The system works together with a Karl Fischer moisture analyzer and gas supply system. By heating samples and transferring released moisture through a controlled carrier gas path into the Karl Fischer titration cell, it enables accurate moisture measurement without direct contact between difficult samples and Karl Fischer reagents.
The KFDO-11 Karl Fischer Drying Oven is widely used in lithium battery materials, plastic particles, chemical materials, and scientific research laboratories, and complies with the moisture testing requirements of GB/T24533-2009 Lithium-ion Battery Graphite Anode Materials.

Performance Features
•   Uniform circular heating design
Sample heating positions are evenly distributed to minimize temperature gradients and improve analysis reliability.
•   Wide temperature control range
Sample heating temperature can be accurately controlled from room temperature to 300℃.
•   Independent pipeline temperature control
Heated transfer lines prevent moisture condensation during sample transportation.
•   Anti-cross contamination design
Sampling pipeline includes reverse blowing function to prevent sample contamination.
•   Digital temperature control system
Microcomputer control with digital temperature display ensures accurate operation.
•   Flexible instrument compatibility
Replaceable injection interfaces allow connection with different domestic and international Karl Fischer moisture analyzers.
•   Multi-sample heating capability
Supports simultaneous heating of up to four samples.
•   Suitable for difficult samples
Ideal for samples that cannot directly contact Karl Fischer reagents.

Working Principle
The KFDO-11 Automatic Karl Fischer Drying Oven uses the principle of thermal moisture release combined with Karl Fischer titration analysis.
The working process includes:
1. The solid sample is placed into the heating chamber.
2. The sample is heated under controlled temperature conditions.
3. Moisture released from the sample is carried by dry gas through the heated pipeline.
4. The moisture vapor enters the Karl Fischer moisture analyzer.
5. The Karl Fischer reagent reacts with the extracted water, and the analyzer calculates the moisture content.
This indirect measurement method avoids chemical interference between the sample and Karl Fischer reagent, making it suitable for reactive, insoluble, or difficult-to-dissolve materials.
