Product Description

This  Vacuum evaporator combination, including concentrator main engine, diaphragm pump and 3L low temperature cold trap, suitable for large sample processing capacity, equipment needs to run for a long time, and have higher requirements for concentration efficiency of scientific research institutions, industrial enterprises, etc., can be used as production instruments. It is applicable to efficient sample concentration in biomedicine, environmental detection and other fields, providing an efficient automatic solution for laboratory sample pretreatment. It is equipped with 1.5ml~250ml EP tubes, glass test tubes, various centrifugal tubes, chromatographic bottles, centrifugal bottles or 96-wellplates, etc., which can quickly and safely evaporate the water and organic solvents in the sample.

Below is a detailed introduction to this vacuum centrifugal concentrator:

Ⅰ Working Principle

When the pressure is lowered, the boiling point of the solvent also decreases. When the pressure is reduced to a certain degree, the solvent can boil and evaporate under relatively low temperature conditions. In order to avoid evaporation and cross-contamination of the sample, high-speed centrifugal rotation technology is used to ensure that the sample will not be sprayed in the sample tube

Ⅱ. Design Features

1. Compact Design: This vacuum centrifugal concentrator is usually designed with a benchtop structure, occupying little space and suitable for placement on standard laboratory workbenches.

2. Easy Operation: It has a user-friendly interface with clear and simple parameter settings, allowing users to get started quickly.

3. Multiple Adapters: Equipped with different types of rotors and adapters, it is compatible with various specifications of test tubes and microplates to meet different experimental needs.

4. Automatic Anti-Suckback Function:  This function can prevent solvent vapor from flowing back into the samples when the machine stops, protecting the samples from contamination.

5. Cold Trap System: A cold trap device is included to capture evaporated solvents, avoiding contamination of the vacuum pump or ambient air.

6. Timing and Temperature Control: Provides precise time and temperature control systems to ensure the samples remain in suitable conditions throughout the process and are not damaged by overheating.

7.Diaphragm pump:Equipped with a chemically resistant diaphragm pump, it delivers high suction power without requiring vacuum pump oil.

Ⅲ. Application Fields

1. DNA/RNA Extraction and Purification: Efficiently recover nucleic acid molecules from cell lysates.

2. Protein Concentration: Reduce the volume of buffer to increase protein concentration, facilitating subsequent analysis.

3. Enzyme Activity Assay: Concentrate enzyme solutions to improve reaction efficiency.

4. Trace Substance Detection: Enrichment of trace components such as pesticide residues and environmental pollutants.

5. Pharmaceutical Development: Concentrate compound libraries during drug screening processes.
