• Liquid Nitrogen Vapor Phase

    Liquid nitrogen vapor phase is a storage method used to preserve biological samples, including cells, tissues, and biological molecules, at ultra-low temperatures (-150°C to -196°C). This method involves storing the samples in a container filled with liquid nitrogen, where they are exposed to the vapor phase above the liquid nitrogen. In this method, the samples…

  • Frozen Cell Vials

    Frozen cell vials are containers used to store and preserve cells for long-term storage at ultra-low temperatures, typically below -80°C. Frozen cell vials can be used for various applications, such as cell banking, long-term storage of valuable or rare cell lines, or for experimental replicates. To prepare frozen cell vials, cells are typically grown to…

  • Cell Concentration

    Cell concentration refers to the number of cells per unit volume of a cell suspension. This parameter is often critical in cell culture and molecular biology experiments, as it can affect the outcome of various procedures, such as transfections, cell-based assays, or protein purification. There are several methods for measuring cell concentration, depending on the…
