Carefully designed and manufactured from borosilicate glass Wall thicknesses are carefully controlled to provide the proper balance between thermal expansion and mechanical strength for greater shock resistance Excellent chemical durability provides contamination-free results and long life…

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 Class A PYREX® volumetric flasks have machine-blown bodies to which are sealed heavy-beaded, heavy-tubing necks, tooled for No. 9 PTFE color-coded keyhole stoppers. For replacement stoppers see No. 7630. The graduation line is sharp and permanent. Large white block letters make the…

For user convenience, PYREX Erlenmeyer flasks are graduated to show approximate capacity. The 25- 50- and 125 mL flasks are satisfactory for use as a weighing bottle. Erlenmeyer flasks come with a PYREX Standard Taper stopper.

Micro Filtering Flasks These PYREX® VISTA™ micro filtering flasks are recommended for microchemical use. The vacuum hose is attached to the flask's sidearm. A funnel is inserted into the neck of the flask through a ground joint or rubber stopper. The applied vacuum facilitates the…

PYREX® VISTA volumetric flasks provide precise volume measurement. The necks are tooled for Standard Taper glass stoppers. The graduation line is sharp and permanent and large blue block letters make the inscription easy to read. The 1 mL and 2 mL sizes are test tube shaped.  These Class A…

Calibrated "to contain" at 20°C Accuracy tolerances approximately twice those specified for Class A

Permanent graduation line Machine-blown bodies Heavy-beaded, heavy-tubing necks are tooled for polyethylene stopper Stopper is made with a closed bottom and is of linear, high-density polyethylene to conform to Standard Taper stopper dimensions

These Class A PYREX volumetric flasks are made from red low actinic stained glass to provide protection for materials sensitive to light. The protective color is an integral part of the flask, which retains its mechanical strength, chemical stability and thermal resistance. The graduation line is…

Calibrated to contain at 20°C Red stripe, through which calibration mark is etched into transparent glass underneath Supplied with plastic snap cap

Calibrated to Class A ASTM E-542 and E-288 Supplied with a certificate of identification Traceable to NIST standards The graduation line is sharp and permanent. Large white block letters make it easy to read. Supplied with a Standard Taper stopper.

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.

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

Heavy-duty rim for longer service Narrow mouth Graduated scale indicates approximate volume The Erlenmeyer design is extremely popular and has been modified for numerous lab applications.

Microvolumetric Class A flasks are individually serialized and supplied with a Certificate of Identification and Capacity.  Flasks are designed for microchemical work in accordance with the recommendations of the Committee of Microchemical Apparatus, Analytical Division of the A.C.S. To…

Narrow mouth PYREX VISTA Erlenmeyer flasks have uniform wall thickness, which provide the proper balance between mechanical strength and thermal shock resistance. Approximate graduations are in durable blue enamel. An extra large marking space is also provided. The Erlenmeyer flasks are designed to…
