Pyrex Volumetric Flask 50ml Class A Technical Overview

The Pyrex Volumetric Flask 50ml Class A is an essential precision measuring instrument designed for the most demanding laboratory environments. Manufactured from high-quality borosilicate 3.3 glass, this flask offers exceptional resistance to thermal shock and chemical corrosion. As a leading laboratory equipment seller, we ensure that every unit meets the stringent ASTM E-288 and ISO 1042 standards for volumetric accuracy.

This specific 50ml model features a machine-blown body with a heavy-beaded, heavy-tubing neck. The primary advantage of choosing a Corning Pyrex 50ml Volumetric Flask is its durability. Unlike standard glassware, the reinforced neck is tooled to provide a secure fit for either a polyethylene snap cap or a ground glass stopper, preventing evaporation and accidental spills during titration or reagent preparation.

Why Buy Pyrex Volumetric Flask 50ml in Bangladesh from A Rahman Scientific?

Finding a reliable laboratory equipment supplier in Bangladesh can be challenging. Many vendors supply lookalike glassware that lacks the thermal stability of genuine borosilicate. Here is why professionals choose us:

High Precision and Traceability

Each Pyrex Volumetric Flask 50ml Class A features a sharp, permanent graduation line. The large white block letters are easy to read even in low-light laboratory settings. For laboratories requiring high-level documentation, we supply flasks that are individually serialized and traceable to NIST standards.

Superior Chemical Resistance

The Pyrex Borosilicate 50ml Flask is designed to withstand aggressive chemicals, including concentrated acids and alkalis. This makes it a long-term investment for any research facility, reducing the frequency of replacements due to glass etching or clouding.

Secure Closure Systems

Whether you choose the Pyrex 50ml Flask with Snap Cap or the version with a glass stopper, you are guaranteed a leak-proof seal. The polyethylene snap caps are particularly popular in educational settings because they are durable and won’t break if dropped.

How to Maintain Your Pyrex Laboratory Glassware

To ensure the longevity and accuracy of your Pyrex 50ml Glassware BD, follow these professional maintenance tips:

• Cleaning: Use mild laboratory detergents. Avoid abrasive brushes that can scratch the interior surface.

• Drying: Do not heat volumetric flasks in an oven above 110°C, as extreme heat can slightly alter the calibrated volume.

• Storage: Store flasks in a dedicated glassware cabinet to prevent chips and cracks.

• Inspection: Regularly check for “stars” or hairline cracks, especially if the flask has been used with hot liquids.

Frequently Asked Questions (FAQ)

What is the difference between Class A and Class B Volumetric Flasks?

Class A flasks, such as our Pyrex Volumetric Flask 50ml, have a tighter tolerance ($\pm 0.05$ ml) and are used for analytical work. Class B flasks have double the error margin and are suitable for general educational purposes.

Is Pyrex glassware heat resistant?

Yes, Pyrex is made from borosilicate glass, which has a very low coefficient of thermal expansion. It can withstand significant temperature fluctuations without breaking.

Where can I buy a Pyrex 50ml Volumetric Flask in Dhaka?

You can purchase it directly from A Rahman Scientific Co., the most trusted laboratory equipment seller in the country. We offer home delivery across Bangladesh.
