Ideal for clinical labs, research facilities, and educational settings, this multitube rack combines function and flexibility in one compact design.

Specifications
 

Tube Size	Wells	Well Diameter	Dimensions Expended	Dimensions Collapsed
15 mL	21	17 mm	10 x 5.4 x 2.8 In 254 x 137.16 x 71.12 mm	10 x 5.4 x 0.8 In 254 x 137.16 x 20.32 mm
50 mL	12	29 mm

 

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

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
