Product Description

I. Overview

The plastic screw cap reagent bottle is one of the most versatile liquid storage containers in the laboratory. Manufactured from high-density polyethylene (HDPE) through precision blow molding, offering excellent chemical resistance, lightweight shatterproof construction, and reliable sealing performance.

Features GL45 standard screw thread for compatibility with most laboratory caps and equipment interfaces (solvent dispensers, HPLC systems, etc.). Equipped with a leak-proof sealing cap to ensure reagent safety during storage and transport.

Available in amber (UV protection for light-sensitive reagents), white, and translucent color options to meet various reagent storage requirements. Bottles feature graduations for easy level monitoring.

🔬 GL45 Thread System:
GL45 is the most common screw thread standard in laboratories — 45mm outer diameter.
GL Standard Series: GL18, GL25, GL32, GL45 — numbers indicate outer diameter in mm.
GL45 Advantages: Universal compatibility with solvent dispensers, HPLC systems, and multi-channel pipettors — reduces adapter costs.

II. Color Selection Guide

Amber: UV absorbent, blocks 200-500nm light — ideal for light-sensitive reagents (vitamins, antibiotics, indicators)
White: Light-blocking — suitable for general reagent storage
Translucent: Easy level viewing — suitable for routine aqueous solutions and buffers

III. Core Performance Parameters

Material: High-density polyethylene (HDPE)
Process: Precision blow molding, uniform wall thickness
Thread Standard: GL45 standard thread
Sealing: Leak-proof cap
Temperature Range: -20℃ ~ 120℃
Chemical Compatibility: Dilute acids (≤10%), dilute alkalis (≤10%), salt solutions, most organic solvents
Incompatible: Concentrated sulfuric acid, nitric acid, benzene, toluene, and strong solvents
Sterilization: Not autoclavable (EtO or γ radiation recommended)

IV. Material & Workmanship

Manufactured from imported food-grade HDPE resin through precision blow molding. Uniform wall thickness with GL45 standard thread for perfect cap compatibility.

All products are assembled and packaged in cleanroom environments to ensure contamination-free surfaces.

Selection Guide

I. By Color

Reagent Type	Recommended Color	Reason
Light-sensitive reagents (vitamins, antibiotics)	Amber	UV protection, blocks 200-500nm light
Routine liquid reagents	Translucent	Easy level viewing
Light-protected storage	White	Complete light blocking

II. By Capacity

8ml / 15ml: Small standards, valuable reagents
30ml / 60ml: Routine small-volume reagents
125ml / 250ml: Routine reagents (most common)
500ml: Bulk stock, mobile phases
1000ml: Large volume reagents, bulk storage

💡 Selection Tip: 250ml GL45 screw cap bottle is the most commonly used size — compatible with most standard caps and equipment.
Choose amber for light-sensitive reagents, translucent for easy level viewing of aqueous solutions.
GL45 thread offers universal compatibility with solvent dispensers and HPLC systems — recommended for lab-wide standardization.

Operation & Maintenance

User Guide

Below are standard operating guidelines for plastic screw cap reagent bottles. 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 reagent
For sterile storage, use EtO or γ radiation sterilization (not autoclavable)

II. Storage Operation

Pour the reagent slowly along the bottle wall
Liquid level should not exceed the shoulder, leaving expansion space
Align the cap with GL45 thread and tighten clockwise to seal
Apply label to the bottle body with reagent name, concentration, preparation date
Store according to reagent requirements (ambient/refrigerated/dark)

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
Do not store corrosive reagents long-term
Store in a dry, cool place away from direct sunlight

💡 From a Seasoned Lab Technician: "GL45 is the universal standard" — GL45 thread fits most lab equipment — prioritize GL45 for compatibility.
"Amber for light-sensitive, translucent for daily use" — Always use amber for light-sensitive reagents; translucent is fine for routine solutions.
"Label the body, not the cap" — Labels belong on the bottle body, not the cap — caps may be swapped or lost.
