False Bottom Tubes

Biosigma False Bottom Tubes are designed for efficient handling and recovery of small-volume samples.

The internal conical bottom design concentrates small sample volumes in a reduced collection area, supporting efficient sample handling and recovery.

Featuring a graduated body and a large labeling area for sample identification, these tubes are available in clear and amber versions to meet different laboratory needs.

Compatible screw caps are available separately or pre-assembled, while colored cap disks provide additional options for sample identification.
