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 PolarSafe cryogenic 2D vials, available in 2 and 5 mL sizes with internally or externally threaded caps, are idea for rapid processing of biological samples. The embedded Datamatrix code at the bottom of each vial along with the corresponding "Code 128" barcode on the body of the vial, saves time and provides accurate organization and tracking of valuable samples.

The 2D vials can be safely stored in polycarbonate boxes (purchase separately). The storage boxes also feature the 2D Datamatrix code and Code 128 barcode to provide automatic identification of both the box and stored vials.

CoolCaddy™ PCR Work Station

  • Maintains 2 to 4° C for up to 5 hours
  • Keeps samples cool, but not frozen
  • Accomodates several different vessel types: Vials, Tubes, Strips, Plates & Reservoirs

Protect your enzymes, reagents and temperature sensitive samples with the new 5-hour CoolCaddy™.  No need for messy ice baths - simply store it overnight in any standard freezer and its ready to hold tubes, plates and reservoirs at 2 to 4° C for an entire morning or afternoon.  CoolCaddy™ is an ideal work station for PCR and especially for any protocol requiring multi-channel pipetting from a reservoir into strip tubes or 96 well plates.  And, if your work is interrupted, just place the whole CoolCaddy™ (complete with samples and reagents) back in the freezer or refrigerator until you are able to resume your experiment.

The CoolCaddy™ offers the highest level of enzyme protection and is essential for all protocols that call for more than 30 minutes of benchtop prep work.  Additionally, the proprietary refrigerant gel protects enzymes, samples and reagents from freezer fluctuations caused by power outages, open doors, and frost-free cycles.

5 mL Snap-Cap MacroTubes®

  • Compatible with standard equipment
  • Easy-open flip top
  • Syringe port in cap
  • Unsurpassed clarity, virgin polypropylene
  • Dual graduations (at every 0.2 mL and 0.5 mL)
  • Certified RNase and DNase-free.

5 mL MacroTubes® scale up the conveniences of standard 1.5 mL tubes for larger volumes. These polypropylene tubes come with an attached cap that provides a tight, leak-proof seal and can be opened (or closed) with one hand. The cap is designed to provide a secure seal from -86°C to 80°C.


They have the same diameter as standard 15 mL tubes for compatibility with centrifuge rotors, etc. They have replaced 15 mL tubes in many applications, reducing plastic waste, storage space, and shipping costs. Contamination of pipettor shafts can be eliminated because the tube length is short enough for standard 1 mL and/or 5 mL tips to reach the tube's conical bottom. The syringe port in the cap is useful not only for needle and syringe access but also for venting internal pressure that has built up due to incubation at higher temperatures.

 

Dimensions: 16.5 x 54 mm (not including rim and cap)
Maximum Centrifugal Force: 25,000 x g (when properly supported in the appropriate rotor)

IsoFreeze® MCT Color-Change Racks

 

Leave the Ice Buckets Behind!
IsoFreeze Color-Changing Racks take the guesswork out of sample preparation!

 

Using proven IsoFreeze temperature maintenance technology, the filled racks maintain a cool (refrigerator) environment on the bench or the workstation platform. This helps maintain a stable environment for PCR reagents, cells, enzymes, or other temperature-sensitive reagents. Industry Standard format tubes, strips, and 96 well plates, in both standard and low profile well shapes, are accommodated and are efficiently cooled in PCR, QPCR, and many other applications.

 

IsoFreeze PCR Racks are manufactured using polypropylene containing temperature-dependent color-change dye giving at-a-glance temperature indication for each well. There is a dramatic change to a contrasting color at 7ºC. IsoFreeze gel technology means the wells will stay cool for up to 4 hours, depending on ambient temperature and other factors.

  • Available in 2 color changing formats
  • Material: Rugged polypropylene and inert gel
  • Maintains temperature of less than 4°C for up to 2.5 or 3.5 hours depending on Rack

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).
