VWR Pyrex Erlenmeyer Flask 40/35 Male STJ 1000 ml

The VWR Pyrex 33985-1L is a 1000 ml Erlenmeyer flask designed for specialized laboratory applications that require a secure, standardized connection. This specific model features a 40/35 male standard taper joint and is manufactured from high-quality borosilicate glass to withstand thermal and mechanical stress. Some common applications include distillation and fractionation, vacuum operations, and chemical synthesis.

Core Performance Features

• Standard Taper Joint: Equipped with a 40/35 male (inner) joint, which allows for a secure, vacuum-tight connection with corresponding female joints on condensers, distillation heads, or manifolds.

• Thermal & Chemical Resistance: Made from Code 7740 borosilicate glass, it is highly resistant to chemical attack and thermal shock. This makes it suitable for heating samples on hot plates or in heating mantles.

• Uniform Wall Thickness: Engineered with consistent wall thickness to provide the optimal balance between mechanical strength and thermal resistance, reducing the risk of breakage during pressurized or high-heat operations.

• Approximate Graduations: Features white enamel graduations from 300 to 1000 ml in 50 ml increments, along with an extra-large marking spot for easy sample identification.
