Product Description
Busy prep areas need volumetric flasks that are quick to close and forgiving if knocked. Pairing Class A accuracy with a snap-on plastic cap, these flasks let you make up solutions precisely, cap them in a second and reduce the risk of spills or chipped stoppers.
This listing is for catalog number 2303A-10: Volumetric Flask, Class A, Snap-Cap, 10 mL, Pack of 6. Bodies are machine-blown from borosilicate glass and fitted with heavy-beaded necks shaped for a snug snap-cap fit. Each flask is calibrated to contain at 20°C, with a sharp, uniform fill line and a large marking square. Sizes range from 10 mL to 1000 mL, each supplied with its matching cap. Add it to your LIGHT LABS order and keep your lab stocked.
