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).

The 5mL Five-O MacroTubes take all of the conveniences of standard 15mL conical tubes and scales 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 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 foam racks are similar to the packaging normally associated with 15mL tubes (upright with caps attached), but they require about 60% less storage space.

    • Opaque Black Tube
    • Compatible with standard equipment
    • Centrifuge at up to 25,000xg
    • RNase, DNase & pyrogen free
    • Unsurpassed Clarity
    • Dual graduations at every 0.2mL and 0.5mL

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
