Oven sample processor 774

The 774 Oven Sample Processor: A Versatile Instrument for Precise Laboratory Analysis

The 774 stands out as a versatile and indispensable instrument for laboratory environments. Designed to meet the diverse requirements of modern laboratories, it is particularly well-suited for processing numerous samples that require heat application. This processor is highly effective in removing moisture or organic solvents from solids and liquids through controlled thermal application.

At the core of its capabilities is the precise determination of moisture using the oven method. When samples are heated in the oven block, they release moisture as water vapor. This vapor is then directed to a measuring cell via a gas stream. The moisture is measured either coulometrically or volumetrically using the Karl Fischer method. This process makes the 774 an ideal choice for complex matrices where moisture determination poses specific challenges.

The growing popularity of the Metrohm 774 Oven Sample Processor is attributed to its ability to deliver high-precision results in demanding environments. The instrument is equipped with a wide range of communication options, allowing seamless integration with various Metrohm titrators, meters, and dosing instruments via its parallel and RS232 serial interfaces. This extensive compatibility allows the 774 to control or be controlled by any device equipped with a suitable communication interface, facilitating its use in complex automation tasks within highly integrated laboratory data systems.

The operational flexibility of the 774 is a key feature that makes it suitable for a wide range of laboratory applications. Although the instrument offers a broad range of commands and configuration options, it remains user-friendly even for routine tasks. The standard methods provided with the instrument are ready to use, and users have the ability to customize and save their own methods to meet the specific needs of their applications, whether for routine tasks or more specialized protocols.

The instrument also allows for the free definition of operational sequences, enhancing its adaptability to various laboratory workflows. Start and end sequences, required before and after sample series, further simplify the process. Additionally, the integrated learning mode facilitates manual setting of command parameters, allowing users to easily create customized operational sequences based on the specific needs of their analyses.

The standard sample rack of the 774 is designed to accommodate up to 36 sample vials, with the option to define special positions for conditioning beakers. This customization capability ensures that the processor can effectively handle a wide variety of samples and conditions, making the instrument extremely versatile for different types of analytical processes.

The Metrohm 774 Oven Sample Processor is a valuable tool for laboratories that require reliable, precise, and flexible sample processing. With its integration capabilities, ease of use, and adaptability, it stands out as an essential instrument for meeting the needs of modern laboratory environments.
