Choosing finger cots comes down to three things: material (latex or NBR), whether you need ESD protection, and size.
For semiconductor, optoelectronics and other static-controlled work, choose the blue ESD NBR finger cots first. Latex cots are more elastic and give better touch for assembling precision parts.
Four types
| Type | Material | Notes |
|---|---|---|
| Yellow | Natural latex, cream | About 1,000 per pack (S), 770 (M), 680 (L) |
| White | Natural latex, white | Contamination is easy to see; common for precision assembly |
| Black | Natural latex, black | Hides marks; for dark work areas |
| Blue ESD | NBR (nitrile), blue | ESD protection; for electronics and semiconductor work |

Sizes
| Size | Finger | Thickness (yellow) | Notes |
|---|---|---|---|
| S | Slim fingers | 0.50 ± 0.03 mm | Slim fingers and fine precision work |
| M | Medium | 0.65 ± 0.03 mm | Most common; fits most people |
| L | Larger fingers | 0.73 ± 0.03 mm | More room to stretch |
A finger cot should fit snugly without squeezing: too tight tires the finger, too loose slips off. For a first order, try a few of each size before buying in bulk.
