ClearSeal screw cap microcentrifuge tube family

The Clearest View of Your Sample

ClearSeal™ screw-cap microtubes are molded from ultra-clear polypropylene for easy visualization of pellets, phases, and volumes. Assembled O-ring screw caps hold a leak-proof seal from −86 °C to +121 °C, so samples stay put in the freezer, the heat block, and the centrifuge.

Every tube is sterile and RNase-, DNase-, and pyrogen-free, and packed 50 to a resealable sterile bag. You open only what you need, and the rest stay protected.

ClearSeal tubes in resealable bags of 50

Resealable Bags Protect What You Don't Use

A 1,000-tube case shouldn't mean 1,000 tubes exposed to the lab. ClearSeal™ tubes ship in 20 resealable sterile bags of 50, so the tubes you haven't used yet stay clean.

Choose printed white graduations for fast volume checks, or non-graduated tubes for a clean labeling surface.

Built for Real-World Workflows

Conical or Self-Standing
Conical bottoms for pelleting, skirted bottoms that stand on the bench.

Printed Graduations
Crisp white markings on graduated 1.5 and 2.0 mL formats.

Loop-Cap Option
C3220-SGL loop caps are easy to grip with gloves.

0.5 mL Formats
Small-volume tubes for precious samples and aliquots.

Generic OEM Versions
C3170 and C3172 are unmarked for reagent kits and private-label packaging.

Color-Coded Caps
Single-color packs of 1000 O-ring caps in six colors.

Tip for Kit Builders

Order C3172 uncapped tubes and C3175 caps separately to control cap color by product or lot, and to fill and cap in your own workflow. Everything is sized to match.

*Centrifugation rating refers to liquids with a specific gravity of 1.0, using appropriate rotors, cushions, and adapters.

Need a −90 °C rating or amber tubes? See ScrewSeal™ Screw Cap Microtubes.

Frequently Asked Questions

Are ClearSeal™ tubes a good alternative to Axygen® screw cap tubes?

For most storage and centrifugation applications, yes. ClearSeal™ tubes are ultra-clear, sterile, O-ring sealed, and packed in resealable bags of 50, with OEM tubes and colored caps for kit builders. Confirm fit in your specific racks and rotor. Axygen® is a trademark of its respective owner; Blue Tiger Scientific is not affiliated.

What is the difference between ClearSeal™ and ScrewSeal™?

ClearSeal™ tubes ship in resealable sterile bags of 50, offer 0.5 mL sizes and printed graduations, and seal from −86 °C to +121 °C. ScrewSeal™ tubes are rated to −90 °C and offer an amber light-blocking option.

Can I buy uncapped tubes and caps separately?

Yes. The C3172 is an uncapped, non-graduated 2.0 mL tube (1000/bag), and C3175 O-ring caps come in natural, blue, green, orange, red, yellow, or assorted. This is ideal for reagent kits and OEM packaging.

Are ClearSeal™ tubes sterile?

All capped ClearSeal™ tubes are sterile and RNase-, DNase-, and pyrogen-free. The C3172 uncapped tubes and C3175 caps are non-sterile.

How fast can ClearSeal™ tubes be centrifuged?

Up to 22,000 × g for liquids with a specific gravity of 1.0, using appropriate rotors, cushions, and adapters.

Is there a loop-cap option?

Yes. The C3220-SGL is a 2.0 mL self-standing, graduated tube with a loop cap.
