Product Description

I. Overview

The plastic reagent bottle (wide mouth) is the primary container for solid reagent storage in the laboratory. Manufactured from high-density polyethylene (HDPE) through precision blow molding, offering excellent chemical resistance, lightweight shatterproof construction, and reliable sealing performance.

The wide mouth design is the key difference from narrow mouth bottles, with neck diameters from 14mm to 53mm (depending on capacity), facilitating powder dispensing, sampling, and weighing. Particularly suitable for solid reagents, powder samples, and granular materials. Equipped with a leak-proof sealing cap to ensure sample safety during storage and transport.

Available in a complete range from 8ml micro to 1000ml large sizes, ideal for routine storage of solid powders, crystals, granular samples and some liquid reagents — the preferred choice for solid sample management in the laboratory.

🔬 Wide vs Narrow Mouth:
Wide Mouth Bottle — Larger neck diameter, facilitates powder dispensing, spatula sampling and weighing — ideal for solid reagents and powder samples.
Narrow Mouth Bottle — Smaller neck diameter, facilitates liquid pouring and dispensing — ideal for liquid reagents. Same HDPE material — choose based on material form.

II. Core Performance Parameters

Material: High-density polyethylene (HDPE)
Process: Precision blow molding, uniform wall thickness
Mouth Design: Wide mouth, neck diameter 14mm~53mm
Sealing: Leak-proof cap (GL standard thread)

Selection Guide

I. By Material Form

Material Form	Recommended Type	Reason
Solid powder/crystals	Wide Mouth Bottle	Easy spatula access
Liquid reagents	Narrow Mouth Bottle	Precise pouring control
Granular samples	Wide Mouth Bottle	Easy pouring and weighing
Viscous samples	Wide Mouth Bottle	Easy scraping and transfer

II. By Capacity

8ml / 15ml: Micro samples, valuable standards, high-activity substances
30ml / 60ml: Small powders, intermediates, routine standards
125ml / 250ml: Routine solid reagents, powder samples (most common)
500ml: Bulk solid reagents, granular samples
1000ml: Large quantity solid materials, bulk stock

💡 Selection Tip: 250ml wide mouth bottle is the most commonly used size for routine solid reagent storage.
For light-sensitive solid samples, choose amber wide mouth bottles.
For highly corrosive solids, choose PFA wide mouth bottles.

Operation & Maintenance

User Guide

Below are standard operating guidelines for plastic reagent bottles (wide mouth). Proper use ensures reagent safety and product longevity.

I. Pre-use Preparation

Inspect for cracks, deformation, and cap integrity
Rinse with distilled or deionized water and air dry
Confirm material compatibility with the sample

II. Storage Operation

Use a clean spatula to add solid powder or sample
Wide mouth allows easy spatula access
Align the cap with the thread and tighten clockwise to seal
Apply label to the bottle body with sample name, purity, date
Store according to sample requirements (ambient/refrigerated/dry)

III. Cleaning & Maintenance

Rinse 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
Store in a dry, cool place away from direct sunlight

💡 From a Seasoned Lab Technician: "Wide is for solids, not for liquids" — Wide mouth bottles are designed for solid powders. While they can hold liquids, pouring is difficult to control — use narrow mouth for liquids.
"Use a clean spatula" — Always use a clean spatula when dispensing solids to prevent cross-contamination between samples.
"Moisture is the enemy" — Solid powders are prone to caking when exposed to moisture. Seal immediately after use and store in a dry environment.
