High-Quality Volumetric Flasks from Huida

250 ml Volumetric Flask for Accurate Measurement

A 250 ml volumetric flask is essential laboratory glassware for preparing reliable standard solutions and accurate dilutions. Constructed of high-quality borosilicate glass, it has a long neck, a single calibration mark, and a tight-fitting glass or plastic stopper, which prevents evaporation and contamination of the contents. Each flask is calibrated to deliver specific volumes at 20°C, which is critical for precision in analytical chemistry, biology, and pharmacy laboratories.

What Are the Advantages of Huida’s Volumetric Flasks?

For consistency and accuracy in Huida’s volumetric flasks, as well as resistance to the chemicals you are using, the company follows ISO 1042 and ASTM standards as approved for quality control.

Key advantages are as follows.

High transparency for clear visibility of the meniscus as the meniscus is the point of the curve in a liquid.

Class A tolerance for precise volumetric measurement.

Tightly fitting interchangeable stoppers of glass or plastic and stoppers of ground glass for chemical compatibility.

Durable borosilicate glass so it can withstand chemical and thermal shocks.

Sizes from 5 ml to 2000 ml.

Reasonable Lab Equipment — 500 ml Volumetric Flask with Plastic Stopper

The 500 ml volumetric flask with plastic stopper lightweight and offers a leak-proof seal and high resistance to acids and alkalis which is convenient for routine solution preparation, titration and calibration work. Plastic stoppers are perfectly designed for labs since they protect against corrosion and are easy to handle without the glass abrading.

Applications

Volumetric flasks are widely used in:

Chemical analysis: preparing precise molar and standard solutions. Clinical laboratories: diluting samples for diagnostic testing. Pharmaceutical production: ensuring formulation accuracy. Educational laboratories: demonstrating volumetric accuracy and solution preparation.

FAQs

Q1: What material are Huida volumetric flasks made from? Huida volumetric flasks are made of high-end borosilicate glass which has thermal resistance and chemical.

Q2: Can the volumetric flask be autoclaved? Huida volumetric flasks can be autoclaved. As a matter of fact they can go through several autoclave cycles and not change in calibration.

Q3: How can I ensure accurate readings with a volumetric flask?

Always read the meniscus at eye level and ensure the liquid reaches the calibration mark at the correct temperature (20°C).
