| Flask Capacity | Neck Size (N/s) |
|---|---|
| 5 to 50ml | 10/19 |
| 50 to 100ml | 12/21 |
| 50 to 250ml | 14/23 |

| 1000ml | 24/29 |
Why a Bumper Guard Is Worth Adding
Volumetric flasks are precision glassware, and a single chip or crack near the neck can throw off a calibrated flask's accuracy or put it out of service entirely. A bumper guard sized to the flask's neck (N/s) absorbs knocks during routine handling, storage and transport between bench and cabinet — a low-cost way to protect a higher-value calibrated flask, particularly in busy teaching labs or shared equipment stores. Match the guard's N/s size to the specific flask capacity using the table above, since sizing is not universal across the range.
