Alkali Scientific Sterile DI Water w/Glass Beads 10mL Tube, 10/Pk
Sterile Deionized Water with glass beads in a 10mL tube is designed for effective sample homogenization and microbial dispersion. The glass beads act as mechanical agitators during vortex mixing, helping break apart cell clusters and release microorganisms from solid or viscous samples. This improves accuracy in microbial enumeration by ensuring uniform distribution of cells. The sterile deionized water provides a contamination free medium for suspension and dilution. This format is particularly useful for processing swabs, cosmetic samples, soils, and other complex matrices where thorough mixing is required. It is widely used in microbiology and laboratory testing for reliable sample preparation and analysis.
Research Products International Corp 5ml MacrewTube Screw Caps, Red, 200 per package
Tubes are manufactured or exceptionally high-quality, transparent polypropylene without the use of slip agents, plasticizers, mold release agents and biocide substances. Offer exceptional centrifugation stability up to 25,000 x g; autoclaving with cap off; (121°C, 20 minutes); withstand temperatures from +121°C to -196°C; and writing surface on flat cap and side wall for quick sample indentification.
