The piece of equipment used to pick up small pieces of solids that are either too small or harmful to touch with your hands is called tweezers.

Tweezers are a versatile tool with many different designs depending on the specific task. Here are some other possibilities depending on the specific situation:

* Forceps: Similar to tweezers but typically used in medical or scientific settings.

* Spatula: A flat, blade-like tool used to scoop or transfer solids.

* Scoop: A small, hand-held container used for transferring solids.

* Vacuum: A device that uses suction to collect small, solid particles.
