A specimen is a sample of something, like a specimen of blood or body tissue that is taken for medical testing. The noun specimen comes from the Latin word specere, meaning âto look.â Biologists collect specimens so they can get a better look at something to study it. The idea is that, with a good specimen, you can learn about an entire group: it's a good representation. That meaning is echoed in the slang use of specimen, a strong, healthy and attractive person.
A collector is a chemical that attaches to the mineral surface and produces a hydrophobic (water-fearing) surface. 1  While certain minerals are naturally hydrophobic and do not require a collector, recovery is often improved when a collector is used. This water-repellent film facilitates the attachment of the mineral particle to the air bubble.
