特點和優勢
- Pyrex® Lifetime-Red™ volumetric flasks with Pyrex® stoppers (volume 200 mL) have the capacity mark etched as a fine line through a narrow red band into clear glass, making a filler unnecessary and giving high legibility, accuracy and permanence.
- The strength of these flasks has been increased appreciably through machine-blown bodies to which are sealed heavy-tubing necks tooled for No. 13 Standard Taper glass stoppers.
- These Class A volumetric flasks have been manufactured to Class A tolerances as established by ASTM E- 694 for volumetric ware, ASTM E-542 for calibration of volumetric ware and ASTM E-288 for volumetric flasks. Calibrated.
