Product details
Description
The TN LAB 10ml Volumetric Flask is engineered for precise laboratory measurements, standard solution preparation, and accurate dilutions. Crafted from heavy-wall borosilicate 3.3 glass, this instrument offers exceptional thermal shock resistance, chemical durability, and structural strength.
Designed to meet ISO 1042 standards, it features a single graduation line on the narrow neck to contain one exact volume with Class A accuracy of plus or minus 0.02ml at 20 degrees Celsius. The flat bottom ensures stability on lab benches and facilitates precise mixing.
Complete with an NS 10/19 tapered joint and an inert PTFE plastic stopper, this flask prevents seizing and sticking, ensuring effortless handling and secure sealing during sensitive chemical procedures.
How to use
- Rinse the flask thoroughly with distilled water before use.
- Add the solute to the flask and dissolve it in a solvent, swirling gently.
- Carefully add more solvent dropwise using a pipette until the bottom of the meniscus aligns exactly with the graduation line on the neck.
- Insert the PTFE stopper and invert the flask multiple times to ensure complete and uniform mixing of the standard solution.

FAQs
What is a volumetric flask used for?
A volumetric flask is a precision laboratory instrument used to measure exact volumes of liquid and prepare standard solutions with high accuracy. It features a flat bottom and a long narrow neck with a single graduation mark indicating the precise fill point.
What does Class A accuracy mean for this 10ml flask?
Class A accuracy indicates the highest level of precision available for volumetric glassware. For this 10ml flask, it guarantees a strict tolerance limit of plus or minus 0.02ml at 20 degrees Celsius, meeting international ISO 1042 standards.
Why is the stopper made of PTFE?
PTFE or polytetrafluoroethylene is chemically inert and highly resistant to aggressive chemicals and solvents. Using a PTFE stopper prevents seizing and sticking inside the ground glass neck, ensuring smooth opening and closing during frequent laboratory use.
