Cleaning and maintenance of nitrogen blower after use


Shanghai Haozhuang Instrument Co., Ltd. develops the LNB brand nitrogen blower, which is energy-saving and environmentally friendly, leading the country.

How it works: There are two ways to speed up evaporation: strengthen the air flow around it and its temperature. Nitrogen is also an inert gas and can also isolate oxygen to prevent oxidation. The nitrogen blower achieves the purpose of concentration through these principles. It will blow nitrogen gas quickly, continuously and controllably to the heated sample surface to achieve rapid concentration of a large number of samples.

Usage: After the nitrogen blower is installed, the chassis is supported in a constant temperature water bath, the water bath power is turned on, the water bath temperature is set, and the water bath begins to heat up. Raise the nitrogen blower, place the samples that need to be evaporated and concentrate on the sample positioning frame, and hold it by the tray. The height of the tray and the positioning frame can be adjusted according to the size of the training sample test tube. Open the needle valve of the flowmeter. Nitrogen reaches the gas distribution plate through the flowmeter and the gas pipe. After the gas is distributed, it is sent to the needle valve tube (installed on the gas distribution plate) above each sample position. Then, adjust the needle valve needle valve through the network calibration. Nitrogen gas is blown to the liquid sample test tube through the needle valve tube and the needle. The needle valve tube can be slid up and down by adjusting the lock nut to adjust the height of the needle. It is better not to splash. Finally, place the nitrogen blower in the water bath until the evaporation and concentration is complete.
It is recommended that users refer to the following methods for cleaning and maintenance.
1. Heating medium: It is best to use distilled water and deionized water, which will prevent scale formation on the water bath wall. Be careful not to use organic solvents as heating medium.
2. Algaecide: When not heated, add algaecide in the water of the water bath to prevent biological pollution. No acidic algaecide should be used, and it should be ensured that the algaecide used will not affect the sample to be processed.
3. Change the water: It is recommended to change the water in the water bath once a week, the longest is no more than one month.
4. Acidic environment: When contacted or exposed to acidic materials, steam or samples, they should be cleaned immediately, neutralized with a moderate sodium bicarbonate solution or other similar solutions, and then rinsed with clean water. Prolonged exposure to acidic substances will damage the instrument. If you must be exposed to acidic substances for a long time, protective measures should be taken.
5. Needle: It should be cleaned after each use of the needle to minimize needle contamination. Organic solvent washing, autoclaving and Soxhlet extraction techniques can be used.

6. Immersion: The bottom of the bath is water resistant but not waterproof. Never immerse the water bath in any liquid or place it where it may occur.

Wall Mirror


Wall mirrors are not only practical items for checking one's appearance but also serve as decorative elements that can enhance the aesthetic of a space. They come in a wide variety of types, each with its own unique characteristics and functions.
One common classification of wall mirrors is based on their shape. Round wall mirrors offer a soft and elegant look. They can add a touch of femininity to a room and are often used in bedrooms or powder rooms. The circular shape creates a sense of harmony and can make a small space appear larger. Square wall mirrors, on the other hand, provide a more structured and modern appearance. They are ideal for contemporary interiors and can be used in living rooms, offices, or bathrooms. Rectangular wall mirrors are versatile and can be found in various sizes. They are suitable for large walls and can create an illusion of depth and space.

Another classification is based on the frame material. Wooden frames give a warm and traditional feel. They come in different finishes such as oak, walnut, or mahogany, and can match various interior styles from rustic to classic. Metal frames, including brass, chrome, and iron, offer a sleek and industrial look. They are durable and can add a touch of sophistication to a room. Plastic frames are lightweight and affordable, making them a popular choice for budget-conscious consumers. They can be found in a wide range of colors and designs, allowing for creative customization.

Wall mirrors can also be classified according to their functionality. Vanity mirrors are designed for personal grooming and usually have adjustable angles and magnification features. They are commonly found in bathrooms and dressing rooms. Full-length mirrors are perfect for checking one's entire outfit and are often used in bedrooms or entryways. Decorative mirrors, as the name suggests, are primarily used for aesthetic purposes. They may have intricate designs, beveled edges, or unique patterns that add visual interest to a wall.

In terms of style, wall mirrors can be divided into traditional, modern, and eclectic. Traditional mirrors often feature ornate frames and classic designs. They are suitable for formal spaces and can add a sense of luxury. Modern mirrors have clean lines and minimalistic designs. They are ideal for contemporary interiors and can create a sleek and sophisticated look. Eclectic mirrors combine elements from different styles, offering a unique and personalized touch. They can be a great choice for those who want to create a one-of-a-kind decor.

Finally, wall mirrors can be classified based on their size. Small mirrors can be used as accent pieces or in tight spaces. They can add a pop of reflection without overwhelming the room. Medium-sized mirrors are versatile and can be used in various locations. Large mirrors can make a bold statement and are often used as focal points in a room.

In conclusion, wall mirrors come in a wide range of classifications, allowing you to choose the perfect one for your specific needs and decor style. Whether you are looking for a practical vanity mirror or a decorative statement piece, there is a wall mirror out there that will meet your requirements. With their ability to reflect light and create an illusion of space, wall mirrors are an essential element in any interior design.
