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)

5 mL Microcentrifuge Tubes with Screw Cap

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).

Specifications

• Compatible with standard equipment
• Withstands up to 25,000 X g
• Dual graduations (at every .2mL and .5mL)

• Autoclavable (122°C) and freezable (-80°C)

5mL SuperClear® snap cap centrifuge tubes are an efficient alternative to 15mL tubes. Designed to fit the same rotors as our 15mL centrifuge tubes, you can use these tubes in procedures that require smaller sample volumes.

The interior surfaces are ultra-smooth with low retention characteristics. Lab testing confirms the superior performance of SuperClear® tubes in light transmission compared to other brands. SuperClear® tubes are more than twice as effective at transmitting light than other brands of 5 mL centrifuge tubes.

SuperClear® tubes feature an extra-thick and durable wall that can withstand centrifugation to 25,000 x G, more than twice some other brands. The ultra-clear polypropylene resin gives you a clear view of the pellet as well as correct color rendition. Designed with ergonomic caps and smooth surfaces.

Tubes have flat, pierceable caps and a side writing surface and are packaged In resealable bags.
 

Avant screw cap tubes and manufactured for the ultimate visibility of your sample.  They come in conical bottom or self standing/skirted and are available in a wide variety of sizes.  The tubes come sterile and DNAse/RNAse free and non-sterile.

• The AV-2***-**  and AVFS tubes are our most versatile.  With a max RCF of 20,000xg, a temperature range of -196°C to 121°C, and a silicone gasket they are great for long term storage.
•  The AVSC tubes fit all standard rotors and can be centrifuged up to 18,000xg.  They have a temperature range of -40°C to 121°C.  The silicone O ring also ensures safe storage of your samples.
