Snap cap macro tubes, 5mL

These new 5ml MacroTubes take all of the conveniences of standard 1.5ml tubes and scale them up for larger volumes. The polypropylene (PP) tubes come with an attached cap that not only provides a tight, leak proof seal, it can also be effortlessly opened or closed with one hand. 

Dimensions:   16.5 x 54mm (not including rim and cap)
Maximum Centrifugal Force:   25,000xg
Temperature range: -86C to +80C

Features:

• Compatible with standard equipment
• Easy-open flip top
• Syringe port in cap
• Unsurpassed Clarity
• RNase and DNase free
• Dual graduations at every 0.2 ml and 0.5 ml

The 16mm tube diameter is identical to the diameter of standard 15 ml tubes, which ensures further compatibility with centrifuge rotors, etc. In many applications, these tubes have replaced 15ml tubes, dramatically reducing plastic waste, storage space and shipping costs. The potential contamination of pipettor shafts is greatly reduced because the 56mm total tube length (vs. 120mm for standard 15 ml tubes) is short enough for standard 1ml or 5ml tips to reach the tube's conical bottom.

The cap is designed to provide a secure seal from -86C to +80C. CapLock Clips are available to maintain the integrity of the seal at extreme temperatures. In incubated/heated applications, it may be "boiled" for up to 10 minutes. At temperatures above +80C, the use of the CapLock Clip is recommended.

Tubes are made of maximum clarity, low-binding virgin polypropylene are are certified RNase and DNase free. Sterile tubes are also pyrogen free. 

They are sized to be compatible with all Benchmark (USA) and standard German-designed equipment, including centrifuges, dry bath block heaters, tube racks and thermal shakers/vortexers.
