    What the Uses of Centrifuge Tubes?

    What the Uses of Centrifuge Tubes? Centrifuge tubes differ from regular test tubes and are explicitly for centrifugation. Centrifugation is when you spin liquids at high speeds to separate their components. Centrifuge tubes are essential to this process. But what goes into purchasing centrifuge tubes? Is it as simple as choosing sterile tubes and going on about your day? There are various considerations to account for when purchasing centrifuge tubes. For example, you can choose glass or plastic centrifuge tubes. In this article, you’ll learn more about the different kinds of centrifuge tubes and what you should consider before purchasing them. Uses of Centrifuge Tubes Centrifuge tubes are used to separate a substance into its components. Below are a few examples of fields that use centrifuge tubes. Instrument Longevity Certain laboratory instruments are sensitive to contaminants. Mass spectrometers and high-pressure chromatography units may become clogged by extraneous materials that find their way into these machines. These instruments work by injecting small samples of material through columns. Next, the analytes are separated from the samples, which are then studied via specialized software. Centrifuge tubes are important to prevent laboratory instruments from being clogged. The idea is to use these tubes to keep analytes separate from any potential substances that could interfere with test samples. Medical Samples Bloodwork is probably what comes to mind when discussing centrifuge tubes. Centrifugation separates organelles from blood cells as the latter sinks. Centrifugation also enables DNA and RNA extraction from cells.   Sample Processing Sometimes, a contaminant can find its way inside a sample that needs analyzing. The goal of sample processing is to remove that contaminant so the sample can be properly studied. This is where centrifugation is key. The centrifugal process separates the sample from the contaminant which leaves a viable specimen to study. To further separate the two substances, the analyst may remove the liquid sample from the tube with a pipette.

    Choosing the Right Pipette Tip for Your Application

    Choosing the Right Pipette Tip for Your Application Pipette tips come in a whole range of varieties – non-sterile, sterile, filtered, unfiltered, long, short, low retention, wide bore and more – and there are many factors to deliberate when choosing the right tip, from the property of the liquid being pipetted to the type of application. Nanjing superfit understands the intricacies and implications of choosing the correct tip and offers a range of high-quality options to meet any need. The first thing to consider when choosing your pipette tip is the required task. For example, sterile tips are essential for cell-based applications, and filtered tips are ideal for pipetting liquids that may contaminate or damage your pipette, such as radioactive or infectious samples. But quality, fit and stable supply are also important factors to ensure your lab work remains uncompromised. Low quality or poorly fitting tips can negatively impact the reproducibility of your results, meaning that you will need to repeat experiments, wasting valuable time and money. Nanjing superfit’s GripTips are designed to fit the company’s broad range of pipettes perfectly and are manufactured under strictly controlled conditions, backed by the VIAPURE statement of quality. And for continuous peace of mind, INTEGRA promises customers a consistent and reliable supply, making sure your research continues without untimely interruptions due to lack of labware. So every time you start your lab work, take a moment to ensure you are selecting the correct tip to maximize the quality and reproducibility of your experiments.

    3 types of pipetting contamination

    3 types of pipetting contamination 1. Pipette-to-sample contamination:  The pipette or pipette tip contaminates the sample. How to avoid it: Use sterilized filter tips, for example, SafetySpace tips from Sartorius, to keep the pipette body free from contaminants. Change the pipette tip after each sample. Autoclave or disinfect the pipette with ethanol regularly. Choose pipettes that are autoclave compatible. For example, Tacta from Sartorius. 2. Sample-to-pipette contamination: Pipetted samples enter the pipette body, contaminating it. How to avoid it: Use filter tips or positive displacement tips to prevent samples from entering the pipette body. While pipetting, hold the pipette in a vertical position. Store pipette in an upright position. Tilt the bottle while pipetting. Avoid splashes of samples from entering the pipette by slowly releasing the button. Choose pipettes equipped with soft ejection feature. For example, Picus or Tacta from Sartorius. 3. Sample-to-sample contamination: Residue pipetted samples are carried over to the next sample. Typically occurs when the same tips are used multiple times. How to avoid it: Change the pipette tip after each sample. Use filter tips or positive displacement tips to prevent samples from entering the pipette body, and into the next sample. Ensure pipette tips make a leak-tight seal on the pipette to avoid sample leaks. For example, Optifit Tips by Sartorius.

    Superfit in ‘Gas Stations in the Mid-Baituan War’

        On September 21, 2020, Gas Stations in the Mid-Baituan War was successfully held in Mercure Nanjing Olympic Centre. Superfit dispatched two outstanding representatives to participate in this business communication. As an advanced foreign trade enterprise, we actively seek change, learn new knowledge, and grasp the new trend of the industry.     This event invited Mrs. Song Chunyan, a senior predecessor in the industry, to share the wonderful experience of “taking orders efficiently”. Through Mrs. Song's sharing, we learned how to correctly understand the needs of customers in the inquiry. We will apply the learning to the practice of work, and promote the development of enterprises to a high-quality and sustainable direction. Nanjing Superfit

    Covid Testing Faces Delays Again As Demand Surges Ahead Of The Holiday

    With the holidays approaching, some companies require employees to return to their offices, and anxiety about the virus increases with the daily case count, and the demand for accurate Covid-19 testing is surging.     In the past week, the average of Covid-19 tests was conducted 1.6 million times a day, compared with a seven-day average of less than 900,000 in July, according to data compiled by the Covid Tracking Project. (Refer from The Atlantic Magazine)     The surge in demand is yet put pressure on the supply chain of PCR molecular tests - the gold standard for Covid-19 testing - leading to long lines for testing, shortages of supplies, and processing delays across the country.     National labs cannot obtain enough necessary testing supplies. The American Clinical Laboratory Association, an industry trade group, previously warned that its members are facing delays or cancellations on orders for critical supplies, such as pipette tips.

FAQ

  • Q1: Can COVID-19 nucleic acid test swab be replaced with cotton swabs?

  • A: You bought your own kit for testing the new crown. You dare not use his throat swab and want to use cotton swabs instead. In this case, it is not possible, because the thing he gives has a mesh on it that is easy to store and cotton swabs are not convenient. So you'd better be equipped, and you'd better go to the hospital and ask the doctor to test you.
  • Q1: What payment methods do you accept?

  • A: We accept payment by T/T in advance, Western Union, L/C. 
  • Q1: How long is your production delivery time?

  • A: For the delivery time, 7-10days for samples, 30days for mass production.
