Alkali Scientific Phosphate Buffered Saline 9mL Tube, 10/Pk
Supplier: Alkali Scientific PBST00
Phosphate Buffered Saline (PBS) is a sterile isotonic salt solution widely used in tissue culture, microbiology, and molecular biology. It is formulated to mimic physiological conditions, maintaining osmotic balance and a neutral pH around 7.4 so that cells remain stable during handling. The 9mL tube format is specifically designed for serial dilution procedures in laboratory testing. By adding 1mL of a liquid sample to the tube, technicians immediately obtain a 1:10 dilution. The saline component prevents osmotic shock that could damage sensitive cells, while the phosphate buffer stabilizes pH during dilution and processing. These tubes are commonly used for preparing microbial suspensions, diluting biological samples, and maintaining cell viability during routine analytical and microbiological procedures.
