Plastic reagent bottles and glass reagent bottles comparison
Reagent bottles are containers used to store various chemical reagents. According to different materials, they are divided into two types: glass material and plastic material. There are thousands of chemical reagents. So what is the difference between these two materials? The raw materials of plastic reagent bottles are generally polyethylene or polypropylene, which can resist the corrosion of most acid and alkali solvents, and are light in weight and not brittle. Generally, solvents with no special requireme
What testing lab supplies are required for the covid nucleic acid test?
The detection accuracy of the new coronavirus nucleic acid is relatively high, because the laboratory needs to meet the following two conditions to be diagnosed as positive: 1. In the same specimen, if the real-time fluorescent RTPCR detection of both targets of the new coronavirus is positive or the detection result of a single target is positive, it needs to be re-sampled or re-tested. If it is still positive for a single target, it will be regarded as positive. 2. Positive r
1. Material At present, the tips on the market are basically made of polypropylene plastic (colorless and transparent plastic with high chemical inertness and wide temperature range). High-quality tips are generally made of natural polypropylene, while low-cost tips are likely to be recycled polypropylene plastic. Yonyue biological pipette tips have high transparency, resistance to organic solvents, and a wide range of temperature resistance: -80℃~121℃, no deformation after high temperature and high pressure, a
Maintenance of manual single channel pipettes
Why do pipettes need care and maintenance? 1. If it is not used for a long time, the range of the pipette should be adjusted to the maximum scale, so that the spring is in a relaxed state to protect the spring. Failure to pay attention to this point will easily cause the piston to fail to rebound. 2. If the pipette needs to be used every day, it is recommended to clean and calibrate it every three months. It can be washed with soapy water or sterilized ethanol, then washe
How to use multi channel pipette?
A complete pipetting cycle Including pipette tips installation - volume setting - pre-wash tip - suction - discharge - unloading Pipette tips installation: The correct installation method is called rotary installation. The specific method is to insert the top of the white sleeve into the tip (whether it is a bulk tip or a boxed tip), and while pressing down gently, Rotate the pipette in the handle 180 degrees counterclockwise. Remember not to use too much force, let alone chop the tip to inst
How to choose laboratory pipette tips?
Classification of pipette tips As a consumable used in conjunction with pipettes, tips can generally be divided into: standard tips, filter tips, low adsorption tips, automatic workstation tips, and wide-mouth tips according to different applications. 1. Standard tips are the most widely used tips, and common tips can be used for almost all pipetting operations, which is the most economical type of tips.

How to use microcentrifuge tubes and precautions
How to use microcentrifuge tubes 1. Because the graduated centrifuge tube is a measuring device, it must be cleaned and dried before use. 2. When reading, be sure to observe the meniscus correctly, otherwise certain errors will be introduced. 3. When using, the number of centrifuge tubes should be determined according to the type of centrifuge. If a centrifuge with double casings is used for a single test, the same vol
How to choose cell culture flask?
The selection of the type of culture flask is usually based on experimental needs and personal habits. The height of the wide-body culture flask is reduced, which helps to save space in the incubator. The bottle neck located in the corner allows the dosing operation to reach the corner of the flask directly. Erlenmeyer flasks and modified Erlenmeyer flasks facilitate pipettes and cell scrapers reaching the corne

When to use filter tips for pipettes?
The pipette is a test instrument in biological research, and the number of its accessories tips used in the test is also very large. The tips on the market are basically made of polypropylene plastic (colorless and transparent plastic with high chemical inertness and wide temperature range). However, with polypropylene, the quality can vary widely: high-quality filter tips are generally made of natural polypropylene, while cheap pipette tips are likely to be made of recycled polypropylene plastic (in this case Next, we can say that its main ingredient is polypropy
How to properly use 96-well PCR plate
The PCR plate is available in transparent and milky white, among which milky white is more suitable for new fluorescence quantitative PCR instruments (such as Bole CFX series, ABI 7500fast and above models, Roche 480 series) that collect fluorescent signals at the top, but if the fluorescence quantitative PCR instrument is the bottom light source , you
Still worried about liquid retention during pipetting? You may not have the right tip
Recently, due to the COVID-19 outbreak, the demand for tips from various biological testing laboratories has been very high. Faced with the sudden increase in demand, low-quality pipette tips from various small manufacturers have entered the market. The pipette tip is an important part of the pipette, which is a kind of laboratory equipment often used in analytical chemistry and molecular biology. Generally speaking, high-quality pipettes work under the action of the piston, which can suck or release the sa
Did you choose the right centrifuge tube?
Plastic centrifuge tube racks are ideal for sample handling and short-term (or long-term) storage of samples. The centrifuge tube rack can withstand -80℃~121℃. High temperature and high pressure sterilization, the centrifuge tube rack can hold 15ml and 50ml centrifuge tubes, and the surface is marked for easy identification. Plastic centrifuge tubes are designed for safety and easy handling, ensuring optimal sample handling. 15 mL and 50 mL conical bottom centrifuge tubes are not only suitable for cell cultur
During the epidemic, nucleic acid detection suddenly changed from a biological term to a well-known hot word. Many people around the world have had more than one personal nucleic acid experience. A key step in nucleic acid detection is nucleic acid extraction, and nucleic acid extraction is inseparable from an important consumable, that is, deep well plates.
Experiment failed? Maybe the problem lies in the small pipette tips!
Experiment failure is always a frustrating outcome, whether in colleges or corporate labs. But sometimes I repeatedly check the experimental steps, but I can't see where the problem is. At this time, perhaps you can turn your attention to the usual inconspicuous experimental consumables. Taking pipette tips as an example, pipetting is an essential operation in the laboratory, but not only the tips that can be loaded are the tips that can be used. In the process of delicate experiments, low-quality tips will not o
Precise pipetting starts with the correct use of the pipette
Correct use of pipettes includes the following steps: 1. Set the volume The principle of range setting is from large to small, so when adjusting the volume, if you want to adjust the vo
Analysis of the reasons for inverted culture after inoculation of microbial culture dishes
Why turn the plate upside down and put it in the incubator? Many new laboratory technicians leave a message or send a message to the editor in the background to ask what is the reason for this? The summary of my own practical experience is: 1. First of all, it is convenient to take and place 2. Inverted culture can prevent contamination: In order to prevent the distilled water appearing on the petri dishes cover

Please accept this Petri dish usage guide~
A petri dish is a glass or plastic round vessel used to hold liquid culture medium or solid agar medium for cell culture. The petri dish consists of a bottom and a lid, and is a chemical device used for culturing bacteria. The main material is glass or plastic. Petri dishes are fragile and fragile, so they should be handled with care and care when cleaning and handling. It is best to clean the used petri dish in time and store it in a safe and fixed place to prevent damage and breakage.
Correct posture for sealing film of PCR plate
Presumably everyone has the experience of "filming", that is, sealing the 96-well PCR plate. Ensure that the sealing film is closely attached to the 96-well plate to prevent the liquid from evaporating, so as to ensure the smoothness of the experiment. Today we will share how to properly seal the film. Usage and precautions of self-adhesive sealing film: (also applicable to aluminum foil film) Step 1 Attach
