The content expressed in this article is Some introductions about 2ml Crimp Vial please feel free to contact me. The injection bottle and 2ml Crimp Vial are the most basic tools for the experimental process, especially the chromatographic experiment process. However, it is difficult to find some valuable information about the sample bottle on the Internet - except for promotional materials and advertisements. Let me talk about the importance of the 2ml Crimp Vial during the experiment: Although the autosampler seems to be insignificant compared to many sophisticated analytical instruments used in the laboratory, the incorrect use of the vial or cap or pad can have a significant impact on the experiment, resulting in experimental efficiency and repeatability. Reduced. Potential problems with incorrect use of vials/caps/slits include: Loss of analyte due to volatilization Chromatographic peaks produced by solvent and septum Mechanical damage to the autosampler Injectability is poor, etc. The poor quality of the glass is mainly poor in water resistance and acid and alkali resistance. When the long-term storage is required, the difference between the good and bad of the glass comes out. When the poor glass is stored for a long time, the inner wall will fall off and interfere with the sample. . Let's talk about the material of the 2ml Crimp Vial: Most of the vials are made of glass. When talking about this material, we must first talk about the linear expansion coefficient, which means that the temperature changes every one degree of temperature change. In short, it is the ability of glass to withstand extreme temperature changes. The lower the coefficient of linear expansion, the greater the temperature change that the glass can withstand. The classification of laboratory glass is based on USP (United States Pharmacopoeia) based on its water resistance. USP Type 1, Class A, 33 Borosilicate glass is the most chemically inert glass and is widely used in laboratories, especially for chromatographic applications. Class I glass consists mainly of silicon and oxygen and contains traces of boron and sodium. It has the lowest dissolution rate and a linear expansion coefficient of 33. USP Type 1, Class B, 51 Borosilicate glass is mainly composed of silicon and oxygen. It contains trace amounts of boron, sodium and alkali metals with a higher content than grade A glass, but it can still be used for laboratory purposes. All brown glass is Class B glass with a linear expansion coefficient of 51. Silanized or deactivated glass is a deactivated borosilicate glass that is organosilylated on the surface of the glass. The glass surface is highly hydrophobic and inert, suitable for pH sensitive compounds, trace analysis and Long-term sample storage. USP Types II, III and NP soda lime glass are less chemically resistant than borosilicate glass. In addition to the glass material, there are some other materials: Polypropylene (PP) is a hard material that can be processed into a variety of colors and has good chemical resistance, suitable for short-term storage of most laboratory chemicals. The tolerance is attenuated over time when aromatic hydrocarbons or halogenated hydrocarbons are used. PP vials are commonly used for ion chromatography due to their low ion content and can be washed with dilute acid and deionized water. The PP vial also reduces the exposure of hazardous materials as it can be directly incinerated after sealing. Polymethylpentene (TPX) is a hard, transparent material with a high melting point and a range of 0°-170°C. Due to its high transparency, TPX vials can replace opaque PP. Its chemical resistance is similar to PP, and TPX vials are typically used where visual samples or high temperature applications are required. The TPX vials are brittle at room temperature.

The content expressed in this article is Advantages and disadvantages of the use of Chemical Vials (vials) for rapid washing cartridges please feel free to contact me. The shortcomings and advantages of this product are reviewed from the perspective of users and me. Let me talk about the advantages first: 1 This washing procedure can indeed wash the Chemical Vials. After washing, the bottle looks really cleaner than the previously washed bottle. Shimadzu HPLC, GC and Agilent HPLC-MS The peaks in the previous solution were not seen on the /MS instrument. 2 It does save a lot of washing time. I used to wash 300 injection bottles in a day. Now 400 injection bottles are finished in 1.5 hours. According to the procedure designed by the inventor, the organic solvent and water are also used. Save a lot, I remember the cardboard instructions said that the total consumption of three organic solvents is not more than 2L, the total consumption of pure water is not more than 25L, the consumption should be an approximate number, but it should be almost the same. Let's focus on the shortcomings below: 1 The washing program designed in the instruction manual is too ideal. It is generally difficult for the laboratory to accumulate 400 sample bottles to be washed, unless the laboratory of the Ministry of Agriculture's pesticide residue certification like us sometimes needs more than 200 injections a day. Bottle, my other classmates used more than 100 a week is not bad. 2 Washing process I don't think it is necessary to wash the 400 sample bottles in batches. The inventor's successive washing design is not wrong to save solvent and save time, but he needs to know that the washing habits of the laboratory are very different, for example, we The laboratory organic washing solvent is washed by the organic solvent used for recycling. These solvents directly dump the waste liquid tank directly into the waste liquid tank. It is indifferent to use more than one use at a time, and there are many laboratories in my class. After washing two or three times directly with soapy water, it is enough to rinse it seven or eight times with water, not to mention the solvent saved. I think I put 200 pieces together (2 injection bottle washing boxes) into a large box, and the big box is ultrasonically washed in the ultrasonic wave, so that the ultrasonic time can be set at will. When I use the organic solvent for the second wash, I can change it into another big box. In doing so, I can buy half of the product, that is, two large boxes and two small boxes, which saves the general purchase cost. 3 Glass Liutong I don`t think it is necessary to buy or not. Why? The inventor said that taking this glass six-way can save a lot of time, 20 seconds can fill 100 injection bottles, the wrong is not wrong, I actually found that 20 seconds can fill 100, 30 seconds in the process of washing the bottle I can wash it again, but during my washing process, I also found that I can directly use the water outlet of the pure water machine to directly fill the water for 1 min, that is, I can wash it in 60 seconds without using the glass. 4 Oh, the biggest drawback is that things are too expensive, these bad boxes actually want me hundreds of oceans, I am so sad. Today, I saw that MD has risen again, and it`s really irritating. It is recommended that you buy half a set, and you must bargain when you arrive.
