Pinch clamp

This Test tube pinch clamp 3D model is a part of Chemistry lab collection.

Why do we need 3D pinch clamps? Frankly speaking, we do not, but our 3D people do. Since the test tubes are widely used by chemists to hold, mix, or heat their 3D chemicals, especially for qualitative experiments and assays, the 3D pinch clamps are essential. Here is the reason why they are needed so badly: 3D pinch clamps are used to hold those tubes, as they may get hot or otherwise dangerous to be touched with bare hands.
