Product Description

I. Overview

The plastic volumetric flask is an essential tool for standard solution preparation and precise dilution in quantitative analysis. Manufactured from high-clarity polymethylpentene (PMP) through precision injection molding, featuring high clarity, smooth surface, and a clear graduation mark.

Available in 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml, and 2000ml sizes. High accuracy meets quantitative analysis requirements. Equipped with a GL standard screw cap for leak-proof sealing, preventing solution evaporation and contamination.

Compared to glass volumetric flasks, plastic flasks are shatterproof and safer to use, and autoclavable. Suitable for pharmaceutical, food, environmental monitoring, research, and teaching applications.

🔬 Product Advantages:
High-Clarity PMP Material — Clear meniscus viewing for accurate volume adjustment
High Accuracy — Meets quantitative analysis standards
GL Screw Cap — Leak-proof sealing to prevent evaporation and contamination
Autoclavable — 121℃ sterilization for aseptic operations

Selection Guide

I. By Capacity

Application	Recommended Capacity	Reason
Micro standards, micro analysis	10ml / 25ml	Small volume, ideal for precious samples
Routine standard solution preparation	50ml / 100ml	Most commonly used sizes
Routine analysis, dilution	250ml / 500ml	Medium volume, versatile
Bulk solution preparation	1000ml / 2000ml	Large volume for batch preparation

II. By Application

10ml ~ 25ml: Micro analysis, standards, precious samples
50ml ~ 100ml: Routine standard solutions, titration (most common)
250ml ~ 500ml: Routine analysis, dilution, batch preparation
1000ml ~ 2000ml: Bulk preparation, stock solutions

💡 Selection Tip: 100ml volumetric flask is the most commonly used size.
For micro analysis, choose 10ml or 25ml.
For bulk preparation, choose 1000ml or 2000ml.
Plastic flasks are suitable for routine aqueous solutions — strong organic solvents should use glass flasks.

Operation & Maintenance

User Guide

Below are standard operating guidelines for plastic volumetric flasks. Proper use ensures volume accuracy and product longevity.

I. Pre-use Preparation

Inspect for cracks, deformation, and cap seal integrity
Rinse with distilled or deionized water and air dry
Confirm material compatibility with the solution
For sterile applications, autoclave before use (121℃)

II. Volume Adjustment Operation

Add the solute to the flask
Add partial solvent, shake to dissolve completely
Continue adding solvent until close to the mark
Use a dropper to slowly add solvent to the mark
Read with eye level aligned with the mark, meniscus tangent to the mark
Secure the cap and invert repeatedly to mix

III. Cleaning & Maintenance

Clean promptly after use and air dry
Stubborn residues: use mild neutral detergent, rinse with distilled water
Never use hard brushes or abrasives on the inner wall
Do not store corrosive reagents long-term
Store in a dry, cool place away from direct sunlight

💡 From a Seasoned Lab Technician: "Read at eye level, meniscus tangent to the mark" — Align eye level with the mark for accuracy.
"Dissolve before adjusting volume" — Dissolve the solute before adjusting to the mark to avoid volume error.
"Invert to mix, release bubbles" — After adjusting, invert repeatedly to ensure uniform solution.
"Do not heat the flask" — Volumetric flasks should never be heated — cool to room temperature before adjusting volume.
