These centrifuge tubes offer high air-tightness and convenient functions.

• Half-plug seal with sealing point
• Triple-thread screw cap
• Wide writing space
• High precision scale
• RNase-/DNase-/Human DNA-free

The sealing point is made of three protrusions inside the lid, one of which fits into the groove on the tube.

The tubes feature a wide writing space on the cap and on a frosted area of the body. The molded graduation does not fade away, and the scale ends at the 0.5 ml line towards the cone.

The large sealing area of the half-plug seal makes the tubes air-tight. The triple-thread screw enables opening and closing with less rotation.
