Test/Sample Tube Closures

Test tube closures ensure samples do not leak or are contaminated by providing a reliable seal. Securely mix or store small samples with these tops that allow one-handed sealing. Offered in a variety of colors, identification is made easier. Closures come in screw and snug-fit plug designs to fit any test tube opening style. Resistant to high temperatures, the versatile test tube closures can withstand heating applications while the chemical resistance guarantees limitless sample compatibility.
