Product Description

I. Overview

The plastic carboy is an essential container for large volume liquid storage and dispensing in the laboratory. Manufactured from high-density polyethylene (HDPE) through precision injection molding, offering excellent chemical resistance and mechanical strength — a safe, shatterproof alternative to glass.

Equipped with a polypropylene (PP) spigot and leak-proof screw cap, with the spigot integrally molded with the bottle body for robust, leak-proof construction. Flow rate can be precisely adjusted by rotating the spigot or handle. Features molded graduation marks for easy volume monitoring.

Available in round and rectangular designs — rectangular design maximizes storage space efficiency. Capacities range from 2L to 50L, suitable for distilled water, reagents, media, and other large volume liquid storage and dispensing applications.

🔬 Design Features:
Round Carboy — Classic design for routine storage and dispensing.
Rectangular Carboy — Space-saving design for lab benches and refrigerators.
Spigot Design — Enables precise liquid dispensing, reducing spillage risk.

II. Core Performance Parameters

Material: High-density polyethylene (HDPE), spigot and cap: polypropylene (PP)
Process: Precision injection molding, integrally molded spigot
Sealing: PP leak-proof screw cap with sealing gasket
Temperature Range: -100℃ ~ 120℃
Chemical Compatibility: Dilute acids, dilute alkalis, salt solutions, most aqueous reagents
Sterilization: Autoclavable (121℃, 15psi)
Safety Certification: BPA-free, food-contact grade compliant

III. Material & Workmanship

Manufactured from imported high-density polyethylene (HDPE) resin through precision injection molding. The bottle body is robust and durable, with the spigot integrally molded to eliminate leak risks. The cap is made of PP material with a silicone sealing gasket for reliable sealing.

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

Selection Guide

I. By Shape

Application	Recommended Shape	Reason
Routine lab bench storage	Round	Classic design, flexible operation
Limited space (refrigerator, fume hood)	Rectangular	Maximizes space efficiency
Large volume liquid dispensing	Round / Rectangular	Choose based on space available

II. By Capacity

2L / 3L / 5L: Small volume storage, routine reagent dispensing
10L: Medium volume storage (most common)
20L / 25L: Large volume storage, media preparation
30L / 50L: Bulk liquid storage, industrial-scale applications

💡 Selection Tip: 10L round carboy is the most commonly used size for routine liquid storage and dispensing.
For space-saving, choose rectangular carboys.
For frequent liquid dispensing, choose models with spigot.

Operation & Maintenance

User Guide

Below are standard operating guidelines for plastic carboys. Proper use ensures safe liquid storage and product longevity.

I. Pre-use Preparation

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

II. Storage & Dispensing Operation

Pour the liquid through the bottle opening
Liquid level should not exceed the shoulder, leaving expansion space
Align the screw cap and tighten clockwise to seal
To dispense, open the spigot valve
Adjust flow rate by rotating the spigot or handle
Close the spigot valve and secure the cap after dispensing

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: "The spigot is the carboy's best feature" — Spigot enables precise dispensing, reducing spills and waste.
"Rectangular saves space" — For refrigerator or fume hood storage, choose rectangular carboys.
"Label clearly" — Large containers are easily confused — label the contents and date prominently.
