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.

DryChill™ Ice-free Cooling Block

 

The DryChill™ cooling blocks are designed to store samples safely on the lab-bench without sample degradation due to temperature increase or fluctuation. Unlike traditional ice buckets, these blocks do not require any ice and are uniquely designed to minimize condensation, resulting in a convenient, mess-free cooling.

 

Each DryChill™ Cooling Block utilizes a proprietary gel refrigerant, designed to maintain cold (but not freezing) temperatures for extended time periods. Once the block temperature begins to warm, the visual indicator alerts the user by changing from purple to pink.

Four blocks are available for accepting a wide variety of commonly used research tubes and plates.

  • Ice-free, stable cooling for sample tubes
  • Unique design reduces condensation
  • Maintains 4°C for up to +200 minutes
  • 4 sizes for various tubes up to 50 mL
  • Visual temperature indicator

Forensic MicroSpin

  • Forensic MicroSpin is a valuable device for the extraction of DNA from crime scene samples.
  • Forensic MicroSpin is specifically manufactured to prevent DNA or RNA contamination of the device prior to use.
  • The receiver tube can be capped to protect the sample for storage or freezing

Spec and Instructions:

    • The device has a filter unit, and a 2ml graduated micro centrifuge tube with an attached cap.
    • The filter unit has an integral perforated bottom that filter acts like a strainer and allows fluids to pass but retains small cloth samples in the filter unit.
    • A cloth sample from the crime scene is cut into small pieces and inserted in the filter unit.
    • Add appropriate solvents or buffers to the cloth sample in the filter unit that will permit extraction of DNA.
    • The filter unit is then placed into the 2ml microcentrifuge receiver tube, and the entire assembly is centrifuged in a microcentrifuge as indicated in the DNA extraction protocol being used by the forensic laboratory.
    • Following centrifugation, the filter unit is removed from the filtrate receiver tube, and the cellular debris in the bottom of the tube can be DNA fingerprinted by the forensic technician.
    • Maximum centrifugal force is 20,000 x g. Non-Sterile.
    • Includes Filter Unit & 2.0ml Receiver Tube
