These 1200uL Pipette Tips, LfTS Fit, are racked, sterile, and come in packs of 960. They mimic microcentrifuge tubes, handling volumes up to 5mL, and fit standard 15mL conical bottom centrifuge tubes for compatibility with existing equipment. Each tube features a frosted marking spot and engraved graduations. The flat top cap is easy to open and close with one hand, and has a thin membrane for simple syringe/needle access. The opaque black tube shields light-sensitive compounds.
