On December 24, 2021, the President of the People's Republic of China issued the Order of the President of the People's Republic of China (No. 103) according to the decision of the National People's Congress and its Standing Committee: December 24, 2021, the thirteenth day of the People's Republic of China The 32nd meeting of the Standing Committee of the National People's Congress revised and passed the "Scientific and Technological Progress Law of the People's Republic of China" (hereinafter referred to as the "Scientific and Technological Progress Law").
The pH meter is a common analytical instrument widely used in agriculture, environmental protection and industry. Soil pH is one of the important fundamental properties of soil. Factors such as the temperature and ionic strength of the solution to be measured should be considered during pH measurement. Tips for using a pH meter: 1. Before using the pH meter, pull off the rubber sleeve on the upper end of the electrode to expose the upper hole.
Protein Purification Equipmen Regarding Protein Purification There are many types of protein extraction and preparation products, their properties are very different, they are similar proteins. The methods are not very different due to the choice of building materials, and they are in different systems. But basic information about most of the key components of the separation effort is still prevalent. Most proteins are soluble in water, dilute salt, dilute acid or dilute alkali solution, and a few proteins combined with lipids are soluble in ethanol and butanol.
The pH meter needs to be used for a long time due to the measurement of samples with different pH values, and the results will have errors. When the measurement error of the pH electrode is large, we should know that some factors have begun to affect the accuracy of the instrument, so we need to calibrate the instrument regularly. So how to quickly restore its measurement accuracy? let's see.
A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. The temperature sensor is the core part of the temperature measuring instrument, and there are many kinds. According to the measurement method, it can be divided into two types: contact type and non-contact type. According to the characteristics of sensor materials and electronic components, it can be divided into thermal resistance and thermocouple.
The advantages of the peek tube material, the board has excellent comprehensive functions that polymer plastics cannot compare, and is suitable for a variety of harsh environments. It has been successfully widely used in automobiles, electronic semiconductors, and electromechanical contrast industries. It is a material for new product development, product life and reliability.
What color are the peek tubes, modified and pure peek tubes. The Chinese name is polyetheretherketone tube. Peek tube has excellent heat resistance than other high temperature resistant plastics, with high strength, high modulus, high fracture toughness and good stability. The peek tube made of high-performance peek material is used in various industries, oil and gas industry and semiconductor industry. For temperature, chemical resistance, creep resistance, thermal stability and compression resistance, peek tube is the material of choice. There are mainly three colors of tubes developed on the market. Three colors are tube colors that are often seen.
Protein purification is widely used in production, protein purification equipment steps for protein purification: 1. To know the coding DNA sequence of the purified protein, consult and related research literature, that is, the gene is highly expressed in those cell functions or enterprise organizational structure, improve the primers for designing the gene, and extract the ARF of the target DNA. It is called the acquisition of different target gene fragments.
What are the commonly used silicone rubber tubes for peek tubes? Commonly used silicone rubber tubes include: medical silicone rubber tubes, food grade silicone rubber tubes, industrial silicone rubber tubes, silicone special-shaped tubes, silicone rubber tube connection accessories and other soft exchange tubes.
Protein Purification System Features about the protein purification apparatus, protein purification apparatus, using his peptide tagged protein and peptide tag for automatic two-step affinity purification design. Fully automated affinity one tag for protein purification. The protein purification system is a fully automatic two-step affinity purification designed with His (His tag) peptide tagged protein and GST peptide tag. An integrated system that is easier to use than conventional gravity flow affinity chromatography, and affinity cleanup and desalting of tagged proteins. There are preprogrammed protocols within the system along with chromatographic purification Profinia kits and buffers, yielding independent, reproducible results. Regardless of the operating value, the Profinia protein purification system obtains a sample for downstream purification in less than 30 minutes.
