Alkali Scientific Phosphate Buffered Saline 9.9mL Screw Cap Tube, 10/Pk
Supplier: Alkali Scientific PBST01
Phosphate Buffered Saline (PBS) is a physiological buffer used in biological research to maintain stable pH and osmotic balance for living cells. This sterile tube contains a precise 9.9mL volume designed to simplify high factor dilution protocols. By adding 0.1mL (100µL) of sample, technicians can instantly achieve a 1:100 dilution in a single step. This format saves time and materials by eliminating the need for multiple sequential dilution tubes. The isotonic saline composition protects cells from osmotic stress, while the phosphate buffering system maintains a stable neutral pH during handling and testing. PBS tubes are widely used for microbial dilution series, sample preparation, and laboratory workflows where consistent dilution accuracy and cell stability are essential.
