Tubes are made of autoclavable polypropylene and are available either individually or in strips of 8 or 12 detachable tubes
Tubes have a gross volume of 1.2 ml but with a cap in place, they will hold 1.1 ml
Caps are made of polyethylene and are not autoclavable
For procedures requiring low surface tension such as protein and nucleic acid work, Simport has developed a special tube (see T100-20LST) using a type of polypropylene specifically designed to avoid potentially harmful lubricants while minimizing liquid retention
