Sample Pretreating

Laboratory sample pre-treatment, also known as sample cleaning or sample preparation, are critical for ensuring that the sample is in an appropriate form for measurement, removing potential interfereneces, and improving the accuracy and reliability of the analysis.

In analytical chemistry, sample pre-treatment can involve several instruments such as Solid-Phase Extraction, Ultra-pure Water Purifier, Stirrer, Mixer and Homogenizer, Filtration and Centrifuge, Digestion, Rotary Evaporator, and Nitrogen Evaporator, depending on the nature of the sample and the analytical technique to be used.

Solid Phase Extraction System

Solid Phase Extraction(SPE) Systems are advanced instruments developed by integrating liquid-solid extraction and liquid chromatography technologies. They utilize solid adsorbents to adsorb target compounds from liquid samples, separating them from matrix and interfering compounds. Target compounds are then eluted with eluents or desorbed by heating, achieving the purposes of separation, purification, and enrichment. These processes reduce matrix interference and enhance detection sensitivity. The systems are applied in food safety testing, agricultural residue monitoring, pharmaceutical & healthcare, environmental protection, commodity inspection, tap water analysis, and chemical production laboratories.

Microwave Digestion System

The LC-IMD Series Microwave Digestion Systems are high-performance digestion instruments specifically designed for chemical analysis, environmental monitoring, food testing, biopharmaceuticals, and related fields. Utilizing advanced microwave heating technology and intelligent control systems, these instruments efficiently and rapidly complete sample digestion processes, ensuring the accuracy and repeatability of experimental results.

Auto Nitrogen Evaporator

Multi-Functional Nitrogen Evaporators/Concentrators are high-efficiency, reliable laboratory instruments designed for sample concentration in chemical, biological, and pharmaceutical applications. By directing streams of gas to accelerate solvent evaporation, they significantly enhance concentration efficiency while maintaining sample integrity and purity. Compatible with diverse sample types and solvents, they are particularly suited for heat-sensitive materials and optimized for single or small-batch sample processing.

Nitrogen Evaporator Dry-Block

The DCY-G Series Dry-Block Nitrogen Evaporators integrate microprocessor control with PID technology to enable high-precision concentration of multiple samples. By delivering rapid, continuous, and precisely controlled nitrogen flows onto heated samples, they accelerate solvent evaporation. By calibrating heating temperatures according to solvents' boiling points and evaporation kinetics, they achieve efficient high-throughput sample concentration.

Intelligent Nitrogen Evaporator Water Bath

The Intelligent Circular Water Bath Nitrogen Evaporator is a high-efficiency concentration system specifically engineered for laboratories. Primarily used for sample concentration in chemical, biological, and pharmaceutical applications, this instrument incorporates advanced design concepts and technology to significantly enhance sample processing efficiency while ensuring sample integrity and purity. Suitable for evaporation of various solvents, it is particularly ideal for handling heat-sensitive substances.

Nitrogen Evaporator Water Bath

The DCY-SY Series Circular Water Bath Nitrogen Evaporators employ purge and trap technology combined with temperature-controlled heating. They utilize inert gases such as nitrogen to rapidly, controllably, and continuously purge the sample surfaces, achieving fast, oxygen-free concentration of sample solutions. These methods offer significant advantages in time savings, convenience, and accuracy. They are widely used in food safety, pharmaceuticals, pesticide residue analysis, clinical pharmacokinetics, and related fields.

Auto Nitrogen Concentrator Angled-Blow Vortex

Angled-Blow Vortex Concentrators are high-efficiency, precision sample concentration instruments widely used in chemical analysis, environmental monitoring, biopharmaceuticals, and related fields. Incorporating advanced angled gas flow and vortex mixing technologies, they enable rapid sample concentration while ensuring uniformity and integrity. Their compact design and intelligent interfaces make them ideal laboratory solutions.
