FAQs
What is a Class A Volumetric Flask with Polyethylene Snap‑Cap?
A Class A Volumetric Flask with Polyethylene Snap‑Cap is a precision laboratory flask calibrated to contain exact volumes with high accuracy. It’s machine‑blown with a sharp, permanent graduation line and fitted with a snap‑cap closure for secure solution handling. These flasks support reliable analytical work.
What does “Class A accuracy” mean?
Class A accuracy means the flask’s volume tolerance is held to strict standards defined by ASTM and ISO specifications, ensuring precise calibration and measurement. Class A flasks are used when high accuracy is critical, such as in quantitative analysis and the preparation of standard solutions.
Why is the polyethylene snap‑cap useful?
The polyethylene snap‑cap fits securely and helps prevent contamination, evaporation, or spillage of solutions. It provides a convenient, reusable closure that keeps contents safe during storage or between experimental steps.
What applications are Class A volumetric flasks used for?
These flasks are ideal for solution preparation, analytical laboratory work, and quantitative experiments that require highly accurate volume measurement. They support tasks such as creating standard solutions for titration or concentration analysis.
What sizes are typically available?
Class A volumetric flasks commonly come in sizes including 250 mL and 1000 mL and beyond, each with a calibrated single fill line. Larger and smaller capacities are available depending on the lab application and required precision.
