Locking Microcentrifuge Tubes

These tubes are engineered with a secure locking system that provides the security of a screw cap microtube with the simplicity of a snap cap tube. 
  • Secure - Maintains sample integrity with locking cap which prevents accidental cap opening and evaporation during centrifugation.
  • Versatile - Single use tubes for laboratory procedures including centrifugation, boiling, incubation, freezing and sample storage
  • Quality - Tubes are made from optimally clear USP Class VI medical grade polypropylene
  • Certified - Manufactured in a class 100,000 cleanroom and are certified to be free from RNase and DNase, Human DNA, Pyrogens, PCR Inhibitors, and ATP.
  • Ease of Use - Tubes feature graduations, writing area, pierceable cap, are autoclavable, and are packaged in zip, re-closable bags. 
Material: Polypropylene (PP)
Temperature Range: -80° to +100°C

SuperClear® Screw Cap Microcentrifuge Tubes

  • SuperClear® tubes have integral molded in seals instead of O-rings than can dislodge.
  • These tubes and caps can be reliably autoclaved for 15 minutes at 122° C.
  • USP Class medical grade resins and packaging for all lab uses.

Reliable Sealing for Freezing and Storage
SuperClear® Screw Cap Microcentrifuge Tubes with molded-in elastomeric seal are ideal for any sample processing application. Excellent for frozen storage or when working with hazardous or valuable materials.

Tubes and caps are autoclavable. Tubes can be centrifuged to 20,000 RCF.

Available in 0.5mL, 1.5mL, and 2.0ml sizes in both conical and freestanding versions. 2.0ml and 1.5ml Tubes have a side writing surface and graduations on some versions.

SuperClear Microcentrifuge Tubes

  • Optically clear resin
  • High centrifuging to 20,000 x G
  • ATP, RNase/DNase and Endotoxin Free (non-pyrogenic)

SuperClear tubes feature an ultra-clear polypropylene resin that gives you a clear view of the pellet as well as correct color rendition.  Designed to be sustainable, these tubes use less plastic than most other tubes and include ergonomic caps with smooth surfaces that help reduce the potential for repetitive strain injury.  The cap also includes a special 90° hinge that makes the cap easier to close while on handed pipetting.  These tubes are designed to stay closed during boiling to protect your sample.

Available in 0.5 mL, 1.7 mL, and 2.0 mL sizes that fit all stand high capacity rotors.  Tubes with snap caps have pierceable caps, a side writing surface and graduations.  Autoclavable (122°C) and freezable (-80°C).

ASLABSUPERCLRTUBES

New sterile microtubes from MIDSCI are manufactured under clean room conditions, using only BioClear co-polymer, an advanced polypropylene that maximizes clarity, centrifugal strength (tested up to 28,000xg) and the usable Temp Range (-90°C to +121°C).

The oversized tube cap (with frosted marking surface), combined with the unique ring & groove closure, enhances the security of the liquid-tight seal, while minimizing the required locking forces for a more ergonomic opening/closing of the tube caps.

All tubes are RNase, DNase and pyrogen free.

  • Sterile comes standard - by electron beam radiation
  • Self-Standing bag - with gusseted bottom
  • Stop-Pops supplied - 10 cap locks in every bag

LabCon SuperSpin™ Microcentrifuge Tubes

  • Ultra-high centrifuging up to 40,000 x G*
  • Optically clear resin
  • Resin will not interfere with DNA or PCR
  • For Phenol/Chloroform vortexing
  • Reduced Thumb Force
  • Autoclavable (122°C) and freezable (-80°C)
  • Packaged in resealable bags
  • Tubes have flat pierceable caps and a side writing surface
  • Graduated

SuperSpin® microcentrifuge tubes were designed with the ability to extract DNA from samples and then amplify that DNA with reliable results in mind.  They can be trusted to spin at high rates and can be opened and closed easily many times to add or remove agents.  The interior surfaces are ultra-smooth with low retention.  The tubes are clear enough to be use in spectrophotometers and have no extractables at the wavelength ranges you use to detect DNA. SuperSpin® microcentrifuge tubes are more than twice as effective at transmitting light than most brands of micro centrifuge tubes.

*Maximum G-force can be affected by organic solvents, multiple spin cycles, or low temperature storage.
