Why Labs Choose This MTC Bio Format
Attached screw caps
Manufacturer-described leak-proof closures are supplied with the tubes.
Two bottom styles
PP is skirted/self-standing; PS has a traditional round bottom.
White markings
Printed graduations and a 12 × 50 mm marking area support identification.
Sterile bags
Ten bags of 100 tubes per case.
Which Configuration Do I Need?
T7950 | 14 mL PP
Transparent polypropylene, skirted self-standing bottom.
T7955 | 12 mL PS
Crystal-clear polystyrene, round bottom; use suitable support.
Not just a material swap
Changing the variant changes capacity and bottom style as well as material.
Identify Samples and Select the Right Support
The white marking area provides space for sample identification, while graduations support approximate visual volume checks. The PP skirted base is self-standing; the PS round-bottom format needs appropriate support. No transport-regulation certification is established by the product name.
Typical Applications
- Routine sample handling and internal laboratory transport
- Culture workflows validated for the selected closure
- Sample preparation requiring screw-cap tubes
Confirm material compatibility and your method’s requirements before use. No additional performance or regulatory certification is implied.
Practical Bench Tip
Select by material, capacity and bottom style together. Keep closures secure and follow your laboratory’s secondary-containment and transport requirements.

Frequently Asked Questions
Are these an alternative to Falcon screw-cap culture tubes?
Both provide sterile screw-cap tube formats, but they are not dimensionally identical. Falcon 352025 is a 16 mL PS round-bottom tube measuring 16 × 125 mm, supplied 1,000 per case. MTC T7955 is 12 mL PS and 16 × 100 mm; T7950 is 14 mL self-standing PP. Match capacity, height, material and support requirements rather than treating them as drop-in replacements. Trademarks belong to their respective owners; comparison does not imply endorsement, affiliation or common manufacturing origin.
What is the difference between T7950 and T7955?
T7950 is 14 mL polypropylene with a self-standing skirted bottom. T7955 is 12 mL polystyrene with a round bottom.
Are the screw caps included?
Yes. Tubes are packed with attached screw caps.
Are the tubes sterile?
Yes. They are packed in sterile bags of 100, ten bags per case.
Are both formats self-standing?
No. Only the PP T7950 is self-standing. Use appropriate support for round-bottom PS T7955.
What dimensions should I use for rack selection?
Both are listed as 16 × 100 mm. The workbook’s T7955 spacing typo is resolved using the manufacturer’s 16 × 100 mm specification.
Are the graduations suitable for precision measurement?
No volumetric accuracy specification is provided. Use calibrated equipment when accurate volume measurement is required.
Does transport mean certified for regulated shipping?
No transport-regulation certification is established here. Follow your sample classification, packaging and secondary-containment requirements.
