Typical Applications

These clamps are used in titrations, burette set-ups, tube holding, and for supporting condensers, funnels, flasks and other laboratory accessories. Finger models hold the item at several points, while paddle versions provide a wider contact surface for cylindrical or elongated pieces. The double burette clamp is intended to keep two burettes upright with clear visibility of the scale, while the remaining references allow the holding system to be adapted to the diameter and geometry of each item.

Overall, this clamp range provides a versatile solution for equipping universal stands and general experimental laboratory set-ups. The combination of different formats, opening ranges and fixing systems makes it easier to select the most suitable reference according to the application, the available space and the type of material to be held.
