Bottle Caps

Bottle caps provide an air-tight seal that ensures that a bottle’s contents are leak- and spill-proof, resistant to temperature and that the bottle can be moved. The most ubiquitous style is the threaded screw cap. Caps are available in different sizes and colors and can be specialized for the type of container they sit upon. Popular cap materials include phenolic plastic, polypropylene and PTFE. Bottle caps can be lined with additional material and can be found in solid design or open design, which calls for a septa or insert for complete closure.

Alkali Scientific Saline 0.85% 5mL Screw Cap Tube, 10/Pk

Saline 0.85% is a sterile isotonic sodium chloride solution designed for suspending and washing microorganisms without damaging their cellular structure. This version features a leak resistant screw cap that improves safety during vigorous mixing and transport. The secure closure allows technicians to vortex samples to create smooth microbial suspensions without risk of spills or aerosol formation. Because the solution maintains osmotic balance, it protects delicate cells from bursting or shrinking during laboratory handling. The 5mL format provides a convenient working volume for microbial suspension preparation, biochemical testing, and sample transfer procedures in microbiology laboratories where sterile and reliable diluents are required.
