Product Description

I. Overview

The PTFE waste liquid tank is manufactured from high-purity PTFE resin through cold pressing and high-temperature sintering. Integrally molded with no welded seams, it offers structural strength, resistance to strong acids and alkalis, and excellent sealing.

Ideal for collection, storage, and transfer of corrosive laboratory waste liquids. Optional bottom outlet valve available for convenient draining. Features graduation marks for easy level monitoring — the ideal container for laboratory waste management.

Available in sizes from 10L to 100L, widely used in pharmaceutical, chemical, semiconductor, environmental testing, and academic research industries.

II. Core Performance Parameters

Purity: High-purity PTFE with ultra-low metal leaching (Pb, U < 0.01ppb)
Operating Temperature: -200℃ ~ +250℃
Chemical Resistance: Resistant to HF, aqua regia, concentrated H₂SO₄, HNO₃, strong alkalis, and organic solvents
Surface Properties: Non-stick, low friction coefficient, easy to clean
Sealing Performance: Sealing cap with optional bottom outlet valve

III. Material & Workmanship

Manufactured from imported high-purity PTFE resin, precision cold-pressed in molds, and sintered in high-temperature furnaces — ensuring dense structure, smooth surface, and bubble-free finish. The integrally molded design eliminates welded seams, removing the risk of seam leakage.

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

Applications

Typical Applications

Analytical Chemistry Labs

Acid digestion waste, organic solvent waste collection

Pharmaceutical Industry

Active ingredient waste, organic waste safe storage

Semiconductor Industry

Etching waste, cleaning waste collection and transfer

Environmental Monitoring

Water analysis waste, heavy metal waste temporary storage

Academic Research

Teaching lab waste, research waste safe management

Waste Type	PTFE Compatibility	Recommended Capacity	Notes
HF-Containing Waste	✅ Fully Compatible	20L / 50L	PTFE is the only reliable choice
Aqua Regia Waste	✅ Fully Compatible	20L / 50L	Fume hood operation
Concentrated Acid Waste	✅ Fully Compatible	30L / 50L	Store sealed
Organic Solvent Waste	✅ Fully Compatible	20L / 30L	Fire and explosion prevention
Heavy Metal Waste	✅ Fully Compatible	20L / 50L	Dedicated container labeling

Selection Guide

I. By Capacity

Lab Scale	Recommended Capacity	Applications
Small Lab	10L ~ 20L	Micro experiments, teaching labs
Medium Lab	30L ~ 50L	Research, testing laboratories
Large Lab	60L ~ 100L	Industrial production, bulk experiments

II. By Drainage Method

Sealing Cap: Standard configuration, ideal for short-term storage and transfer
Bottom Outlet Valve: Optional, ideal for large tanks requiring frequent draining

💡 Selection Tip: Choose a tank capacity 2～3× your daily waste generation to provide buffer capacity. For highly corrosive waste (HF, aqua regia), PTFE is the only reliable choice. For frequent draining, choose the bottom outlet valve configuration.

Operation & Maintenance

User Guide

Standard operating guidelines for PTFE waste liquid tanks. Proper use and maintenance significantly extend product life and ensure laboratory safety.

I. Pre-use Preparation

Inspect the tank for cracks, deformations, and ensure the sealing cap is intact
Clean the tank inside and out with ultrapure water or appropriate solvent to remove manufacturing residues
Ensure the tank is placed on a stable, well-ventilated surface
If equipped with a bottom outlet valve, check valve sealing

II. Waste Collection Operation

Place the tank in a stable, well-ventilated designated area
Open the sealing cap and carefully pour waste into the tank to avoid splashing
Fill volume should not exceed 90% of capacity to allow for expansion
Seal the cap promptly after each addition to prevent volatilization and odor spread
Monitor graduation marks regularly and record level changes

III. Waste Transfer Operation

Confirm the sealing cap is secure before transfer — close the bottom valve if equipped
Use a dedicated cart or handling tool — avoid dragging
Keep the tank upright during transfer to prevent tipping
Upon arrival, transfer waste to designated disposal containers per regulations

IV. Cleaning & Maintenance

Routine Cleaning: Clean promptly after use with ultrapure water or appropriate solvent
Stubborn Residues: Soak in dilute nitric acid — PTFE's non-stick surface makes cleaning easy
Valve Maintenance: Check valve sealing regularly — replace seals as needed
Storage: Store clean and dry in a clean environment

💡 From a Seasoned Lab Technician: "Waste management is the first line of defense for lab safety" — Different waste types should be segregated — never mix incompatible wastes (e.g., acids with alkalis, oxidizers with reducers).
Place waste tanks in secondary containment trays to contain accidental spills.
Clearly label each tank with waste type, hazard classification, and accumulation date.
For large tanks (> 50L), a bottom outlet valve is recommended for safer, easier draining.

⚠️ Safety & Compliance Checklist

Labeling

Clearly label with waste type, hazard classification, and date

Protective Equipment

Wear safety goggles, lab coat, and acid/alkali resistant gloves

Ventilation

Waste storage areas must maintain good ventilation

Compliance

Waste management should follow laboratory safety regulations and environmental requirements

Do not

Segregation: Different waste types must be stored separately — never mix
