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.

25 mL Centrifuge Tubes

  • Fits most 50 mL rotors - Rim eliminates need for adapter
  • Printed graduations - From 5mL to 2mL
  • Compact low-profile design - Minimizes shipping, storage, and waste
  • Gamma sterilized - RNase, DNase, & Pyrogen free

MTC Bio's 25 mL tube is the newest addition to our family of screw cap conical tubes. Closing the obvious gap between 15 mL and 50 mL tubes, they are ideal for any application that requires more than 15 mL and less than 50 mL, including midipreps, general sample prep, centrifugation, mixing and storage.

Aside from the reduction in freight costs, storage space and plastic waste, the 33% reduced height and large diameter design (which is identical to 50 mL tubes) allows for faster re-suspension of pellets and 100% recovery of small samples. Concerns about cross-contamination (a frequent result of accidental contact between the pipette and the inner wall of a 15 mL tube) are eliminated by the hood-friendly, low profile, wide diameter format.

Additionally, the tubes have a 360° support rim, just below the cap. Similar to 1.5 mL tubes, this rim allows the tube to fit into most racks, blocks, shields and rotors without requiring adapters. Made of high clarity polypropylene, MTC Bio 25mL conical tubes can withstand up to 17,000 xg maximum RCF* and are supplied sterile, certified RNase, DNase and pyrogen free and packed in racks or bags of 25 tubes with screw caps attached.

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

DuoClick™ Two Position Screw-Cap Culture Tubes

  • New patent pending screw-cap!
  • Aerobic culturing at first click
  • Anaerobic after second click
  • Printed graduations
  • Flat, markable screw-cap

DuoClick™ tubes feature a unique, patent pending screw closure system. DuoClick™ tubes completely eliminate the excess force, splashing and general frustration of traditional snap-cap culture tubes. The advanced cap design includes two distinct positions for aerobic and anaerobic culturing. Just rotate the cap 1/4 turn to the first click to secure the cap in the aerobic position. Or, rotate it another 1/2 turn past the second click for a leakproof, airtight seal for anaerobic culturing.

DuoClick™ tubes are available gamma sterilized, with screw caps attached, and in our exclusive ready-to- use rack packaging. Polypropylene tubes can be centrifuged at up to 4,000 x g.

15 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.

FlowTubes™ for Flow Cytometry Instruments

  • Compatible with FACS instruments
  • Available with 35 um strainer cap, standard cap, or no cap
  • Clear polystyrene
  • 5 mL capacity
  • 12 x 75 mm

Designed for Fluorescence Activated Cell Sorting / flow cytometry equipment. To ensure consistent compatibility with the automated instrument, the diameter and wall thickness is held to very tight tolerances. The tubes are available with the standard two-position culture cap, no cap at all, or with a cap that contains a 35 um nylon mesh screen. These tubes are primarily used to collect dissociated samples for subsequent processing in automated flow cytometry instruments.

 
Cell Strainer Caps

 

These cell strainers are ideal for detaching, isolating and straining cells from clusters and tissues. Their built in compatibility with 12 × 75 mm culture tubes and FACS tubes makes them especially useful for pre-sorting and preparing samples for fluorescence-activated cell Sorting (FACS). Typically, a 35 um porous mesh is used to obtain a single-cell suspension and to prevent clogging in FACS instrumentation. However, a multitude of FACS users have cited applications requiring finer pore sizes for a higher level of anti-clog protection. Others require a larger pore size for pre-sorting and/or for more efficient rapid flow. 

  • Color coded by pore size
  • E-Beam sterilized (SAL 10 -6)

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

5 mL Microcentrifuge Tubes with Screw Cap

 

Our new 5mL MacroTube has the convenience of a 1.5mL tube but scaled up for larger Vols. In many cases, these can replace 15mL tubes, dramatically reducing plastic waste, storage space and shipping costs. Additionally, the 56mm length (vs. 120mm for 15mL tubes, greatly reduces the risk of contamination of pipettor shafts, allowing 1mL or 5mL tips to easily reach the bottom.


The tubes are made of high clarify, low binding virgin polypropylene and are certified RNase/DNase free. The 16mm diameter is identical to standard 15mL tubes, thus ensuring compatibility with existing centrifuge rotors. Other equipment, specially designed for 5mL tubes is available.


The MacroTubes are suppled with 20mm(OD) caps that seal smoothly and completely with a single 360° turn. Useable from -86 °C to 110 °C, they are a valuable vessel for boiling and low temperature sample preservation. Choose from non-sterile bulk packaging, or sterile rack packaging (upright in foam racks with caps attached).

Specifications

  • Compatible with standard equipment
  • Withstands up to 25,000 X g
  • Dual graduations (at every .2mL and .5mL)
  • Unsurpassed clarity
  • RNase and DNase free

Culture Tubes

  • Available in Polypropylene or Polystyrene
  • Dual-position snap Caps attached or ordered separately
  • Molded graduations on attached cap versions
  • Sterile, RNase, DNase, pyrogen, and cytotoxin free
  • Compatible with all standard equipment

 

These culture tubes are available in both 12 × 75 mm (5 mL) or 17 × 100 mm (14 mL) capacities. Low-density polyethylene (LDPE) snap caps can be attached in two positions. The first position allows for the flow of air both in and out of the tube enabling aerobic culturing. The second position offers a leak-proof and air-tight seal making it ideal for anaerobic culturing and/or sample storage.

 

The tubes are available in two plastic polymers. Crystal clear polystyrene (PS) tubes withstand temperatures from 0°C to 70°C, while durable transparent polypropylene (PP) tubes withstand temperatures from -86°C to 121°C.

 

Tubes are available with caps attached and printed graduations or without caps and graduation-free. Polystyrene tubes may be centrifuged at up to 2000xg. Polypropylene tubes withstand higher centrifugal forces, up to 4000xg.

All tubes and caps come sterilized to SAL 10-6 and are RNase, DNase, pyrogen, and cytotoxin-free.
