PTFE Test Tube is a chemical-resistant laboratory container for holding, preparing, mixing, and handling small-volume chemical samples. Made from polytetrafluoroethylene (PTFE), it is suitable for laboratory applications involving many acids, alkalis, solvents, and corrosive reagents.
JAIFUXIN supplies PTFE Test Tubes in 5 mL, 10 mL, 20 mL, 30 mL, and 50 mL capacities, with both flat-bottom and round-bottom designs available. Custom dimensions can also be manufactured according to drawings or samples.
PTFE Test Tube Sizes
| Capacity | Bottom Design | Material |
|---|---|---|
| 5 mL | Flat Bottom / Round Bottom | PTFE |
| 10 mL | Flat Bottom / Round Bottom | PTFE |
| 20 mL | Flat Bottom / Round Bottom | PTFE |
| 30 mL | Flat Bottom / Round Bottom | PTFE |
| 50 mL | Flat Bottom / Round Bottom | PTFE |
| Custom | Flat Bottom / Round Bottom | PTFE |
For custom production, tube diameter, height, wall thickness, and bottom geometry can be specified according to the application.
Flat-Bottom PTFE Test Tube
Flat-Bottom PTFE Test Tubes have a stable base that allows the tube to stand upright on a flat laboratory surface without a separate tube holder.
This design is convenient for sample preparation, temporary sample storage, reagent handling, and laboratory procedures where the tube needs to remain upright during use.
Typical uses include:
- Sample preparation
- Reagent handling
- Chemical storage during testing
- Laboratory mixing
- Material testing
- Analytical procedures
Round-Bottom PTFE Test Tube
Round-Bottom PTFE Test Tubes have a curved bottom with no flat internal base.
The rounded geometry eliminates the internal corners found in flat-bottom designs and can be useful where the sample needs to collect toward the bottom of the tube or where a continuous internal surface is preferred.
Round-bottom tubes normally require a suitable rack or holder to remain upright.
Flat Bottom vs. Round Bottom
| Feature | Flat-Bottom PTFE Test Tube | Round-Bottom PTFE Test Tube |
|---|---|---|
| Bottom Shape | Flat | Rounded |
| Stands Upright | Yes | Requires Support |
| Internal Bottom | Flat | Curved |
| Sample Collection at Bottom | Standard | More Concentrated Toward Center |
| Typical Use | General Sample Handling | Laboratory Processing & Sample Collection |
| Available Capacities | 5–50 mL | 5–50 mL |
The appropriate design depends on the laboratory procedure and how the sample needs to be handled.

PTFE Test Tubes for Chemical Handling
The main advantage of a PTFE Laboratory Test Tube is its chemical resistance.
PTFE resists a broad range of acids, alkalis, solvents, and other aggressive chemicals. This makes it useful for laboratory procedures where glass or conventional plastic test tubes may have compatibility limitations.
Typical applications include:
- Chemical sample preparation
- Acid and alkali handling
- Reagent testing
- Analytical chemistry
- Semiconductor laboratory processes
- Material testing
- Pharmaceutical research
- Chemical research
- High-purity material handling
Chemical compatibility should be confirmed for the specific chemical, concentration, temperature, and exposure conditions.
Custom PTFE Test Tubes
JAIFUXIN manufactures custom PTFE test tubes when standard capacities or structures do not match the application.
Customizable items include:
- Capacity
- Tube diameter
- Overall height
- Wall thickness
- Flat bottom
- Round bottom
- Bottom thickness
- Opening dimensions
- Other drawing-specific features
Production can be based on a dimensional drawing or physical sample.
