…make the inscription easy to read. The 1 mL and 2 mL sizes are test tube shaped.  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.

…An additional extra large volume size is permanently screened onto the flask body for easy volume identification. These flasks are calibrated "to contain" and designed to meet Class A, ASTM tolerances for volumetrics. Flasks are Lot Traceable with certificates of compliance available.

With barrel-shaped Standard Taper glass stopper Calibrated to contain at 20°C

The strength of these flasks has been increased appreciably through machine-blown bodies. Sealed, heavy-beaded, heavy-tubing necks are tooled for snap-cap fit. Graduation line is sharp, permanent and large; white block letters make the inscription easy to read. 1 mL and 2 mL sizes are…

These PYREX VISTA volumetric flasks are designed for use by customers that do not require the precision accuracy of our Class A capacity flasks. The shape, body and wall are the same as regular flasks but display the large blue marking spot and designation "PYREX VISTA" unique to the PYREX…

Similar to 4997B13 series, but with protective PVC coating Coating promotes longer product life and greater safety and helps contain glass and contents should breakage occur Autoclavable and microwaveable to 121°C (250°F) Resistant to thermal shock With PYREX Standard Taper…

Borosil® Wide Mouth Class A Volumetric Flasks are individually calibrated by automatic, laser-controlled calibration equipment. Supplied with standard taper glass stoppers. Flasks comply with ASTM E-288, Class A. 20mL option is not covered in ASTM. 5mL, 10mL, and 20mL options have…

Low actinic stained glass provides protection for materials sensitive to light. The protective color is an integral part of the flask, which retains the mechanical strength, chemical stability and thermal resistance of PYREX brand hardware.
