Product description

Packaging and quantity
This set contains approximately 50 polypropylene microcentrifuge tubes (50 ±2%), supplied loose in a compact bundle for easy storage and retrieval. Each tube is clear for visual inspection and carries visible graduations on the side for quick volume checks.

Materials and dimensions
Manufactured from high-transparency polypropylene (PP), the tubes resist common chemicals and tolerate a wide temperature range. Each tube holds 1.5 mL, measures about 10.6 mm in diameter and about 41 mm in length. A frosted patch on both the tube body and cap provides space for written IDs or labels.

Design and features
Tubes have a conical bottom to concentrate small volumes and an attached snap-fit lid that closes with a distinct click to reduce spills and evaporation. The snap cap is designed for one-handed opening and closing, and the cap geometry includes a thumb flip area for easy access. Walls are molded to be free of visible bubbles or inclusions.

Performance and safety
Rated to withstand temperatures from roughly −80 °C up to +121 °C, these tubes are suitable for cold storage and standard autoclave cycles. They are produced without added plasticizers or fungistats and are free of heavy-metal contaminants. The material is compatible with many molecular-biology and routine-chemistry tasks, though always verify compatibility with aggressive solvents.

Typical uses
Ideal for small-volume biological samples, reagent aliquots, cosmetic or fragrance samples, essential oil blends, seed storage, craft pigments, and similar applications. Their compact size makes them convenient for transport, sample distribution and small-batch testing.

Quality assurances
Products are inspected prior to sale to ensure they are new and defect-free. Users report reliable sealing during transport and routine handling. If you need tubes for microcentrifuge use, these are shaped and sized to fit most standard rotors and adapters.

Package contents
50 x polypropylene microcentrifuge tubes (1.5 mL capacity, clear, with hinged snap caps).

Pros

Secure snap-cap prevents spills and minimizes evaporation
Wide temperature tolerance (≈ −80 °C to +121 °C)
Frosted label areas and clear graduations for easy ID

Cons

Only 1.5 mL capacity — not for larger samples
Disposable by design — limited reuse recommended
Caps may feel stiff until broken in with a few openings

VerdictThese 1.5 mL microcentrifuge tubes deliver reliable sealing and good chemical and temperature resistance for routine lab and hobby tasks. The hinged snap caps provide a secure, single-handed closure and the frosted marking zones make labelling easy. They’re ideal for small-volume sample storage, transport, and short-term reagent holding. Expect consistent dimensions and transparent walls for visua

Reviews

Kingdom Citizens👑 5/5

Makes my DIY lab smoother

Simplifies handling of small samples and reagents at home. Easy to open and close.
Nathan B 5/5

Exceeded my needs

Worked perfectly in my microcentrifuge and kept samples sealed during transport. I carried a few in my pocket for hours and didn’t notice leaks or odors. Sturdy and dependable for field use.
Álvaro GM 5/5

Useful for on-site testing

Used them for field detection work. They’re practical, though after opening and closing several times a couple lost their perfect seal.
Kayte Branch 5/5

Ideal for small blood draws

Great for tiny blood samples from my chickens. Very compact — only use if a small aliquot is sufficient for your assay.
Ricardo Martinez Ibañez 5/5

Exactly what my lab needed

Met expectations for routine lab use — consistent shape and reliable caps, good value for stocking common aliquots.
LTC 5/5

Good size for pollen collection

Large enough to hold pollen without being bulky. Seals easily and would not want a smaller size for this task.
mzm6030 5/5

Handy around the workbench

I use these to mix and age small perfume and essential oil blends before scaling up. They stay closed and let scents marry without leaking.
J 5/5

Perfect for seed packets

Work well for dividing seeds into small sets for my small business. Reliable and consistent.
Devin 5/5

Great seed storage option

I store planting seeds in these until planting season. They protect seeds and are easy to label.
V. B. 5/5

Leakproof for travel

I fill drops for travel so I don’t have to count on the go. They’re very tight and can be reused after a good rinse.
J. montagna 5/5

Solid cap design

Right diameter and a lid that snaps firmly. The thumb flip makes single-handed use simple.
