Clear colored, 0.5mL Protein LoBind Safe-Lock microcentrifuge tube maximizes sample recovery by significantly reducing sample-to-surface binding without the use of any type of coating. A combination of specially developed technology and ultrapure selected polypropylene (PP) ensures best recovery rates of valuable samples. LoBind material guarantees maximum sample recovery for improved assay results. This Safe-Lock microcentrifuge tube is free of surface coating (such as siliconization), eliminating the risk of sample interference. PCR clean quality batch tested and certified by an independent laboratory for reliable purity. Protein LoBind consumables are best suited for work in protein research, mass spectrometry, protein array sample preparation, and storage of peptide, antibody, or virus samples. Supplied as 4 cases of 100 tubes for a total of 400. Material: Polypropylene (PP). Tube Capacity: 0.5mL. Feature: Protein LoBind. Tube Color: Clear. Purity: PCR Clean. Eppendorf® #: 925000088.
