Minimize surface binding and maximize target molecule recovery with Marketlab Flat Top Siliconized Micro G-Tubes. Manufactured from ultra-clear polypropylene with a proprietary internal siliconized coating, these microcentrifuge tubes prevent protein, nucleic acid, and sample adhesion to the tube walls. Featuring a leak-resistant flat snap cap that provides a write-on surface for clear specimen identification, they ensure high sample retention during centrifugation, boiling, freezing, and sensitive molecular biology procedures.
