What are the advantages of the plastic 15 ml centrifuge tubes?
15ml centrifuge tubes can be divided into glass tubes, plastic tubes and steel tubes according to the material, and today we will mainly talk about plastic tubes. The advantages of 15ml plastic centrifuge tubes are transparent or translucent, its hardness is small, and the samples can be removed by puncture method. The disadvantages are easy to deformation, poor resistance to organic solvent corrosion, short service life. Plastic centrifuge tubes have a cap, which is us
Description of several common types of centrifugal tubes
Centrifuge tubes are very common in laboratories, where centrifuges are used to spin specimens to separate solids from liquid chemical solutions. Centrifuge tubes can be made of glass or plastic and resemble miniature test tubes with conical tips. It is a cylindrical calibrated glass vessel mounted in a centrifuge tank for the analysis and separation of various materials. Usually laboratory technicians test solid-liquid or immiscible liquid samples in centrifuge tubes.
Classification and application of three common types of centrifuge tubes
1.Plastic centrifuge tubes The advantage of plastic centrifuge tube is transparent or translucent, it has little hardness, and the gradient can be removed by puncture method. The disadvantages are easy to deformation, poor resistance to organic solvent corrosion, short service life. Plastic centrifuge tubes have a cap, which is used to prevent sample leakage, especially for radioactive or corrosive samples, a
Tell us about the common categories of centrifuge tubes
The tubes used for sample collection are generally lyophilized tubes or centrifuge tubes, blood collection tubes are used, plasma samples are collected with anticoagulant, serum samples are not required. Detection of an indicator of the sample should be collected at least 50 microliters, samples collected for short-term storage is placed in -20 ℃ storage conditions (about a month, long-term storage at -80 ℃ storage, remember that the sample is prohibited to repeatedly freeze and thaw.
Analysis of the phenomenon of "small black dots" during cell culture dish experiments
Cell culture dish is suitable for medium-sized culture of cells and tissues, and can also be used as temporary and storage containers in a variety of experiments such as weighing, separating and processing tissues or cells. Before use to be cleaned and disinfected, culture dishes clean or not have a greater impact on the work, can affect the pH of the culture medium, if there is the presence of certain chemicals, will inhibit bacterial growth.
Study of ELISA plate and Microplate reader for plant enzyme activity analysis
ELISA plates can be divided into ELISA 96 Well Plate, ELISA 48 Well Plate, etc. according to the number of wells. Since the ELISA Microplate is mainly used with the microplate reader, the current microplate reader on the market has up to 96 wells, so the ELISA Plates are the most commonly used. are also 96 wells. In mammalian cell-based research, microplate readers are mainly used for routine molecular detection (such as nucleic acid, protein concentration and enzyme activity analysis, etc.); signal transduction research (such as the detection of some cell signali
The instructions for suction and discharge of serological pipettes are worth studying!
A serological pipette is a measuring device used to accurately pipette a certain volume of solution. As a measuring instrument, it is only used to measure the volume of the solution it releases. It is a slender glass tube with a bulge in the middle. The lower end is beak-shaped, and a marking line is engraved on the neck of the upper end, which is a sign of the exact volume removed. Before using the serological pipette, select the range and pipette type, and then check the pipette mark, accuracy level, scale mark
Treatment of uneven cell distribution during cell culture plate assays
The cell culture plate is made of high quality polystyrene with a round hole and flat bottom, produced using ultra-precise molds and fully automated production processes, and individually packaged in plastic. This cell culture plate is a disposable cell culture plate with tissue culture treatment on the inner surface, which is suitable for the culture of walled cells and also for the culture of suspended cells. The ergonomic design of the cell culture plate makes it easy to operate. The non-slip design on the side makes it easy to hold and reduces the contact area
Overview of sterilization techniques for cell culture dishes
Cell culture dishes are particularly suitable for medium-sized cultures of cells and tissues, and can also be used as staging and storage containers in a variety of experiments such as weighing, separating and processing tissues or cells. They are available in a variety of diameter sizes and include both surface-treated and untreated options, with uniform thickness, a distortion-free bottom, and a ring-shaped protrusion on the lid that is closely integrated with the bottom to facilitate storage and reduce media volatilization.
How to choose the right ELISA plate for you?
There are many types of microplates, and people often do not know how to choose? how to choose? Today, Yongyue will learn the selection skills of the microplate with everyone! 1. According to the difference of the bottom of the ELISA plate, it can be divided
Cell culture FAQ In cell culture experiments, we sometimes encounter many problems. In order to save cells, we need the right remedy! As long as you grasp these 5 points, saving cells is a small case~ The sample itself 1. cellular senescence 2. individual differences (check the initial test report of the sample) Problems with the cel
Is the ELISA plate white or transparent?
The raw material of Yongyue ELISA plate is special material - polystyrene, which is a safe, reliable and effective carrier in ELISA experiments, and plays an important role in the adsorption of antigens, antibodies or antigen-antibody complexes. Yongyue ELISA plate adopts a unique surface treatment process, which can show ideal experimental results. It is often used in enzyme-linked immunosorbent assays, such as immunization, identification of transgenic products, and medical clinical diagnosis.
Did you choose the right PCR consumables?
What is the polymerase chain reaction? Polymerase chain reaction (PCR) is a molecular biology technique used to amplify a specific segment of DNA to a sufficient amount for structural and functional analysis with the involvement of a DNA polymerase and a nucleotide substrate. One of the factors affecting P
A single aspiration of the liquid gives us an accurate sample for testing. Even if the sample volume is less than 1 μL, it still helps labs detect chemicals, screen for disease and amplify DNA for further testing. However, pipetting can be a repetitive and boring task for laboratories. While a 1-μL sample may be an efficient use of a fluid for testing, test equipment often requires the delivery of dozens or hundreds of samples, each requiring liquid tran
Precautions for laboratory elisa plate
According to different classification standards, ELISA plates have different classifications. 1. According to the number of wells, it can be divided into 96 wells and 48 wells, of which 96 wells are the most commonly used now, because the elisa microplate is used with the microplate reader. The elisa 96 well plate is also required when purchasing, and the manufacturer basically made a 96-well plate in order to adapt to the market. 2. According to the difference

Pipette tips on the market today are basically made of polypropylene plastic (a colorless, transparent plastic with a high chemical inertness and a wide temperature range). However, the same polypropylene can vary greatly in quality: high quality tips are generally made of natural polypropylene, while cheap tips are most likely made of recycled polypropylene plastic (in this case, the most we can say is that it is mainly polypropylene). In addition, most of the tips in the manufacturing process will also add a small amount of additives, the more common additives a
What is the situation of culture dish contamination? What are the countermeasures for each of them?
