Type and structure of the purification workbench
The commonly used purification workbench is divided into three types: vertical flow purification workbench, horizontal flow purification workbench and biological purification workbench. The purification workbench is divided into a single work table and a double work table from the number of operators, and is structurally divided into a conventional type and a new push-pull type and a self-circulating type. The Vertical Flow Purification Workbench is a local air purification unit that provides a sterile clean working environment. It is widely used in medical and health, biopharmaceuticals. Food, medical science experiments, optics, electronics, sterile room experiments, sterile microbiological tests, cell culture, plant tissue culture, etc. require scientific and production departments for local clean sterile work environments. The frame is made of cold-rolled steel plate, and the upper air supply and the lower work surface can be separated for easy movement. The diffuser plate of the air outlet of the workbench is equipped with an illumination fluorescent lamp and an ultraviolet germicidal lamp. The purification work area operation panel is made of transparent plexiglass. The horizontal flow purification workbench is a horizontal one-way flow type local air purification device, and the box body is made of thin steel plate, and an adjustable air volume fan system is adopted. Keep the wind speed in the work area within the required range. It is a versatile purification workbench that is widely used in a variety of applications where local purification is required.
principle
The working principle of the purification workbench is that the three-phase motor is used as the blast power, the power is about 145~260W, and the air is blown out through the "super filter" composed of special microporous foam sheets, which form a continuous flow. The dust-free and sterile ultra-clean air laminar flow, the so-called "high-efficiency special air", removes dust, fungi and bacterial spores larger than 0.3 μm. The flow rate of the purified air is 24 to 30 m/min, which is sufficient to prevent the pollution caused by the nearby air. This flow rate does not prevent the burning of the instruments by the alcohol lamp or the Bunsen burner.

Automatic Nucleic Acid Extractor
Nucleic acid extraction instrument is an instrument that automatically completes the nucleic acid extraction of samples by applying the supporting nucleic acid extraction reagents. Widely used in disease control centers, clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety testing, animal husbandry and molecular biology research and other fields.
Using magnetic beads as the carrier, using the principle that magnetic beads adsorb nucleic acid under high salt and low pH value, and separate from nucleic acid under low salt and high pH value, and then move the magnetic beads or transfer the liquid to realize the entire extraction and purification process of nucleic acid. Due to the uniqueness of its principle, it can be designed into a variety of throughputs, which can be extracted from a single tube or 8-96 samples, and its operation is simple and fast. It only takes 30-45 minutes to extract 96 samples, which greatly improves the The experimental efficiency is low and the cost is low, so it can be used in different laboratories, and it is the mainstream instrument on the market.
Features of Magnetic Bead Nucleic Acid Extractor
1. Enables automated, high-throughput operations.
2. Simple and fast operation.
3. Safety and environmental protection.
4. High purity and high yield.
5. No pollution and stable results.
6. Low cost and easy to be widely used.
7. Different types of samples can be processed simultaneously.
