Test Tubes and Racks
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).
There are so many other quality choices and options for all of these products.
The assorted color polypropylene pestles come complete with 1.5 mL microcentrifuge tubes. These are packaged 10/box and 20 boxes per case.

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)
Multi-Purpose Test Tubes 12 x 75 mm
Precision-molded from premium-grade plastics and ideal for routine laboratory analysis and procedures. We have applied the lessons learned from over 27 years of manufacturing experience to produce tubes that perform at their highest level. Our tubes are rigorously inspected by our Quality Assurance Department to ensure they surpass our exacting specifications. These tubes are ideal for a wide range of laboratory applications. They are available in several sizes, and from three materials, to meet a variety of needs.
- - All of the tubes are plastic (polystyrene, polypropylene or polypropylene-copolymer), thus preventing the problem of broken glass.
- - Polypropylene is chemically resistant, autoclavable and virtually unbreakable.
- - Polystyrene is clear like glass.
Note that caps are ordered separately. These tubes are not available sterile.

Five-O™ 5 mL MacroTubes® - Opaque Black
The 5 mL Five-O MacroTubes take all of the conveniences of standard 15 mL conical tubes and scale them down for space efficiency and decreased natural resource consumption. Useful from -86°C to 110°C, these tubes are a valuable resource for boiling and for sample preservation at very low temperatures. Additionally, the 56 mm length (vs. 120 mm for 15 mL tubes, greatly reduces the risk of contamination of pipettor shafts, allowing 1 mL or 5 mL tips to easily reach the bottom.
The foam racks are similar to the packaging normally associated with 15 mL tubes (upright with caps attached), but they require about 60% less storage space.
- Opaque Black Tube
- Compatible with standard equipment
- Centrifuge at up to 25,000 x g
- RNase, DNase & pyrogen free
- Unsurpassed Clarity
- Dual graduations at every 0.2 mL and 0.5 mL

50 mL PP Centrifuge Tubes
Our 15mL, 30mL, and 50mL centrifuge tubes are made of premium polypropylene for clarity and centrifugal strength. Tubes and caps may be frozen at temperatures as low as -86C. The maximum centrifugal force is 12,000xg for the 15mL tubes, 7,000xg for the 30mL tubes, and 15,000xg for the 50mL tubes*. Caps have a flat top surface for easy marking and labeling. C2605 and C2630 feature a ‘skirted’ bottom that allows the tubes to stand upright without a separate test tube rack. The C2600 series of centrifuge tubes, self-standing or not, are leakproof to 95 kPa/14psi.
*Refers to liquids with a specific gravity of 1.0, using appropriate rotors, cushions, and adapters.
- Sterile, RNase, DNase, pyrogen, and cytotoxin free
- Available racked, NEW! Eco-Racked or bagged
- Compatible with standard rotors
- Frosted marking surface
