Pipette Holder

thingiverse

Support for lab vacuum tubes ensures that aspirating pipettes remain elevated, with two base sizes available: one fits a 15mL tube holder perfectly, while the other securely accommodates a 1.5mL microtube stand. To maintain precise control over the system, use an M4 screw to adjust pressure by tightening or loosening the "screw cap", effectively holding the tube firmly in place at all times.
