From test tubes and racks to the labels and boxes you’ll use them with. MIDSCI has got your needs covered.

 MIDSCI has a wide assortment of test tubes, including top-notch centrifuge tubes your research depends on. We carry everything from sterile centrifuge tubes that we promise won’t buckle during spins to specialty centrifuge tubes that are completely blacked out to preserve your light sensitive compounds.
 
We also have freezer racks and autoclavable racks, stackable storage boxes and freezer boxes, general storage containers and cryogenic storage refrigerators and tanks.
 
And let’s not forget the labels! Wash-off labels, removable labels, and labels that will never come off (if you need that).

SuperClear™ Culture Tubes and Caps

  • Ultra-clear resin
  • Colored tubes available
  • Medical grade (U.S.P.) packaging
  • Thicker walls will not crush

These precision-molded, conical and round bottom tubes are perfect for a multitude of general laboratory uses. Precision crafted of extra clear virgin polypropylene in natural and colors or clear virgin polystyrene. Tube caps are made of low-density polyethylene for a secure seal and are available in a fluted plug style or dual position design that permits sample aspiration.

Polypropylene tubes are autoclavable to 122°C and freezable to -80°C. Polystyrene tubes are not autoclavable but have a nominal temperature range between 90°C and -40°C. Polyethylene caps are not autoclavable but are available pre-sterilized with many of the tube packages.

Polypropylene tubes can be centrifuged to 3000 RCF and polystyrene tubes will withstand 1500 RCF. (RCF; Relative Centrifugal Force, is not equivalent to RPM)

Gel Crusher Spin Column

 

Rapid Gel Fragmentation for DNA Recovery.

 

Gel Crusher Spin Columns provide a fast, efficient, and consistent method for gel fragmentation, replacing traditional crush-and-soak or manual gel breaker steps. Designed with 600 uM filtration pores, these columns enable quick and uniform fragmentation of agarose or acrylamide gel slices, saving time and increasing DNA recovery yields.

 

Ideal for workflows in molecular cloning, PCR cleanup, restriction digests, DNA sequencing, and labeling protocols, the Gel Crusher simplifies the preparation of gel fragments for downstream purification and elution steps.

 

Simply insert the Gel Crusher column into a 2 mL microcentrifuge tube, add your pre-cut gel slice (prepared using a gel cutter or razor blade), and centrifuge at max speed (~15,000 x g) for 5 minutes. The gel will be forced through the 600 uM pores, producing small, uniform fragments that can be easily pipetted using wide-bore tips into NaCl or other solutions.

 

This process creates a fine slurry that enhances elution efficiency and improves access to the target nucleic acids, significantly reducing incubation and processing time.

 

Key Features

  • Efficiently breaks gel slices into uniform fragments
  • Eliminates manual crush-and-soak steps
  • Increases DNA yield and recovery efficiency
  • Fits standard 2 mL microcentrifuge tubes
  • Compatible with standard benchtop centrifuges (up to 15,000 x g)
  • 600 uM pore size ideal for agarose or acrylamide gels
  • Simplifies downstream processes: elution, filtration, incubation
  • For use in PCR, cloning, digestion, sequencing, and more 

Reversible Racks

  • Choose 60 well (5 x 12) or 96 well (8 x 12) formats
  • Reversible racks, accept 0.5 and 1.5 to 2.0 mL microtubes
  • Alphanumeric marking on each well
  • Made of polypropylene
