Product Description

I. Overview

The plastic wash bottle is one of the most commonly used rinsing and dispensing tools in the laboratory. Manufactured from low-density polyethylene (LDPE) through precision blow molding, offering flexibility, durability, lightweight construction, and good chemical stability.

The flexible bent tip design is the key feature — the nozzle can be bent to any desired angle for precise rinsing of glassware inner walls and solvent dispensing. Flow is controlled by squeezing the bottle body, making operation simple and intuitive. Equipped with a leak-proof sealing cap to ensure solvent safety during storage.

Available in standard and tall styles, with capacities ranging from 150ml to 1000ml, suitable for glassware rinsing, solvent dispensing, chromatography column washing, and more.

🔬 Style Comparison:
Standard Style — Classic design, compact bottle, suitable for routine laboratory rinsing and solvent dispensing.
Tall Style — Taller bottle with larger capacity, ideal for extended rinsing operations and continuous use.

II. Core Performance Parameters

Material: Low-density polyethylene (LDPE)
Process: Precision blow molding, flexible and durable
Tip Design: Flexible bent tip, bendable to any angle
Dispensing: Squeeze control, adjustable flow
Sealing: Leak-proof cap
Temperature Range: -20℃ ~ 80℃
Chemical Compatibility: Dilute acids (≤10%), dilute alkalis (≤10%), salt solutions, most organic solvents
Sterilization: Not autoclavable

III. Material & Workmanship

Manufactured from imported food-grade LDPE resin through precision blow molding. The bottle body is flexible and durable, returning to shape quickly after squeezing for consistent flow. The bent tip is flexible and can be adjusted to any angle for convenient rinsing.

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

Selection Guide

I. By Style

Application	Recommended Style	Reason
Routine glassware rinsing	Standard	Compact design, flexible operation
Large volume rinsing	Tall	Larger capacity for extended use
Column washing	Standard / Tall	Depends on solvent volume
Confined space operation	Standard	Shorter bottle height

II. By Capacity

150ml: Small volume rinsing, valuable solvent dispensing
250ml: Routine glassware rinsing (most common)
500ml: Large volume rinsing, batch operations
1000ml: Extended continuous rinsing, column washing

💡 Selection Tip: 250ml standard style is the most commonly used wash bottle size for routine glassware rinsing and solvent dispensing.
For extended continuous rinsing, choose 500ml or 1000ml tall style.
For light-sensitive solvents, choose amber wash bottles.

Operation & Maintenance

User Guide

Below are standard operating guidelines for plastic wash bottles. Proper use ensures solvent safety and product longevity.

I. Pre-use Preparation

Inspect for cracks, deformation, and tip integrity
Rinse with distilled or deionized water and air dry
Confirm material compatibility with the solvent
Fill the bottle with the desired solvent and seal the cap

II. Rinsing Operation

Bend the tip to the desired angle
Aim the tip at the target glassware or surface
Gently squeeze the bottle body to control flow
Release the squeeze to stop flow after rinsing
Return the tip to the original position and seal the cap

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: "Three keys — flexible tip, squeeze control, leak-proof seal" — The tip bends to any angle, squeeze force controls flow, and sealing prevents evaporation.
"Dedicated bottles for different solvents" — Use dedicated wash bottles for different solvents to avoid cross-contamination.
"Seal immediately after use" — Always seal the cap immediately after use to minimize evaporation and contamination.
