Product Description

I. Overview

The PTFE reagent bottle is manufactured from high-purity PTFE resin through cold pressing and high-temperature sintering. PTFE offers exceptional chemical resistance and is inert to almost all chemicals and solvents, making it ideal for storing strong acids (including hydrofluoric acid), strong alkalis, aqua regia, and various organic solvents.

The bottle features a professional leak-proof design that provides reliable sealing without the need for an inner cap or liner. Wide-mouth bottles are suitable for solid powders and viscous liquids; narrow-mouth bottles are ideal for liquid dispensing and pouring, reducing evaporation and spillage risks.

Available in sizes from 30ml to 10000ml, widely used in pharmaceutical, chemical, semiconductor, environmental testing, and food analysis industries.

II. Core Performance Parameters

Purity: High-purity PTFE with ultra-low metal leaching (Pb, U < 0.01ppb)
Operating Temperature: -196℃ ~ 260℃, short-term up to 300℃
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: Professional leak-proof design, reliable sealing without inner cap

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 cap and body are made from the same PTFE material for complete chemical compatibility.

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

Applications

Typical Applications

Chemical	PTFE Compatibility	Recommended Mouth	Notes
Hydrofluoric Acid (HF)	✅ Fully Compatible	Narrow	PTFE is the only reliable material
Aqua Regia	✅ Fully Compatible	Narrow	Avoid long-term high-temperature storage
Conc. H₂SO₄ (98%)	✅ Fully Compatible	Narrow	Seal to prevent moisture absorption
Conc. HNO₃ (65%)	✅ Fully Compatible	Narrow	Store away from light
NaOH (50%)	✅ Fully Compatible	Wide	Viscous liquid — wide mouth recommended
Methanol/Ethanol	✅ Fully Compatible	Narrow	Avoid direct sunlight
Acetone	✅ Fully Compatible	Narrow	Seal to prevent evaporation
Hexane/Petroleum Ether	✅ Fully Compatible	Narrow	Flammable — ensure ventilation

Selection Guide

I. By Storage Medium

Storage Medium	Recommended Material	Recommended Mouth
Hydrofluoric Acid (HF)	PTFE (only reliable choice)	Narrow
Aqua Regia	PTFE	Narrow
Conc. H₂SO₄ / HNO₃	PTFE	Narrow
Strong Alkali Solutions	PTFE	Wide/Narrow
Organic Solvents	PTFE	Narrow
Solid Powders	PTFE	Wide
Viscous Liquids	PTFE	Wide

II. By Capacity

30ml ~ 100ml: Micro reagents, standard solutions, precious samples
250ml ~ 500ml: Routine laboratory reagent storage
1000ml ~ 2000ml: Large volume reagents, mobile phases
5000ml ~ 10000ml: Bulk reagents, industrial-scale storage

III. By Purity Requirement

Trace Analysis (ICP-MS, ICP-OES): PFA recommended — ultra-low metal leaching, translucent for easy level viewing
Routine Analysis (HPLC, GC): PTFE is sufficient
Semiconductor Ultra-pure Chemicals: PFA or high-purity PTFE recommended

💡 Selection Tip: When in doubt about the storage medium, PTFE is the safest choice — it is inert to almost all chemicals. For level viewing, choose PFA (translucent) or use a level indicator. Large capacity bottles with handles or carrying features are recommended for easier handling.

Operation & Maintenance

User Guide

Standard operating guidelines for PTFE reagent bottles. Proper use and maintenance significantly extend product life and ensure laboratory safety.

I. Pre-use Preparation

Inspect the bottle for cracks, deformations, and ensure the cap seal is intact
Clean the bottle inside and out with ultrapure water or appropriate solvent to remove manufacturing residues
For trace analysis applications, soak in 10% nitric acid for 24 hours, rinse thoroughly with ultrapure water, and dry

II. Filling Operation

Place the bottle on a stable surface. Wide-mouth bottles can be filled with powder using a scoop or funnel
Liquids can be added via funnel or direct pouring — use a glass rod to guide the flow and prevent splashing
Fill volume should not exceed 90% of capacity to allow for expansion
After filling, tighten the cap to seal. PTFE has self-lubricating properties — no need to over-tighten

III. Storage Conditions

Room Temperature Storage: Recommended 15℃ ~ 30℃, away from direct light
Low Temperature Storage: PTFE withstands -196℃ — suitable for liquid nitrogen sample storage
High Temperature Storage: Long-term storage ≤ 260℃, short-term ≤ 300℃
Ventilation: Volatile organic solvents should be stored in fume hoods or well-ventilated areas

IV. Cleaning & Maintenance

Routine Cleaning: Clean promptly after use with laboratory detergent and a soft cloth or sponge
Stubborn Residues: Soak in dilute nitric acid — PTFE's non-stick surface makes cleaning easy
Sterilization: Autoclave (121℃, 15-20min) or dry heat sterilization (160℃, 2h)
Important: Do not use hard brushes or abrasives — they may scratch the inner wall, affecting sealing and cleanability

V. Disposal

Discard used PTFE reagent bottles according to laboratory waste management regulations
PTFE is not combustible — avoid incineration
After emptying chemical residues, recycle as plastic waste

💡 From a Seasoned Lab Technician: "A reagent bottle is not a universal container" — Always verify chemical compatibility before filling. PTFE is inert to most chemicals but NOT compatible with molten alkali metals (e.g., Na, K) and elemental fluorine.
For light-sensitive reagents, choose amber bottles or external light-shielding packaging.
The cap seal is a consumable — replace if sealing performance degrades.

Care & Notes

⚠️ Safety & Compliance Checklist

Chemical Safety

Verify compatibility of storage medium with PTFE before filling

Labeling Requirements

All reagent bottles must be clearly labeled with chemical name, concentration, preparation date, and safety information

Do not

Pressure Safety: Do not over-tighten caps when storing volatile solvents — internal pressure may build up
Handling Safety: For large bottles (> 2000ml), use carrying handles or carts — avoid carrying by hand
