Chemglass CG-1506-23 Glass 1000mL Heavy Wall Single Neck Round Bottom Flask, with 24/40 Standard Taper Outer Joint

Chemglass CG-1506-23 Glass 1000mL Heavy Wall Single Neck Round Bottom Flask, with 24/40 Standard Taper Outer Joint Lowest new price: $32.06
List price: $37.06
Brand: Chemglass
Model: CG-1506-23

The Chemglass CG-1506-23 1000mL heavy-wall round-bottom flask is used for uniform liquid heating. The single neck has a 24/40 standard taper outer joint, and has a 130mm diameter body. Round-bottom flasks provide uniform heating. This flask is made of clear borosilicate glass for durability, chemical- and temperature-resistance, and high mechanical strength under harsh conditions, such as mechanical washing. Borosilicate glass has a low coefficient of thermal expansion and is resistant to thermal stress. The flask meets ASTM International E438, Type 1, Class A specifications for low-expansion borosilicate glass. Boiling flasks are used for heating and boiling liquids, quality testing, sampling, and research, and in lab applications in chemistry, education, research, and life science applications.

Flasks are glass or plastic containers for storing or collecting chemical samples or solutions in scientific laboratories. They come in a variety of sizes and shapes and are designed for a wide range of scientific processes. Erlenmeyer flasks, introduced by German chemist Emil Erlenmeyer in 1861, are shaped like a cone with a wide, flat base that narrows to a neck opening, which can be closed with a stopper or cap.

Chemglass manufactures laboratory glassware and equipment. The company, founded in 1946, is headquartered in Vineland, NJ.

Features:

  • 1000mL heavy wall round-bottom flask for uniform heating or boiling of liquids and ease of swirling
  • Borosilicate glass for clarity, strength, heat-, and chemical-resistance
  • 130mm diameter and 24/40 standard taper outer joint
  • 500 degree C maximum short-time temperature
  • Meets ASTM International E438, Type 1, Class A specifications for low-expansion borosilicate glass

Round-bottom flasks (also called round-bottomed flasks, Flasks, round bottom, or RB Flasks)having spherical bottoms are more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface. Because of the spherical bottom, cork rings are needed to keep the round bottom flasks upright. When in use, round-bottom flasks are commonly held at the neck by flask clamps on a stand. The flasks are usually used in heating or boiling a liquid, in distillation as distilling flasks and receiving flasks for the distillate, used as the distilling flasks in rotary evaporators. Laboy glass flasks are heavy wall designed, made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glass and annealed at 800 degree Celsius, can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.

Features:

  • Single neck
  • Round bottom flask
  • With 24/40 joint
  • Capacity of 1000Ml
  • Made by hand blowing
