Microtubes
Single-use containers designed to hold microliter to milliliter quantities of liquid. Products may be sterile/non-sterile, come with or without a variety of caps (screw, tether, snap), and may be suitable for use in microcentrifuges.
High quality standard snap cap microtubes, or microcentrifuge tubes, are essential for the safe processing of low to medium sized sample volume applications in clinical chemistry, biochemistry and molecular biology. Ideal for protein research, mass spectrometry, protein array, sample preparation, microcentrifugation and sample storage, they are available in a variety of colours, including amber and black for light sensitive samples.
The snap cap provides a safe, liquid-tight seal and some flat top caps include a needle insertion spot. Some microtubes are also available with additional safety lock snap caps to minimise sample loss during the centrifugation process and to provide added security when working with samples that are radioactive or which pose a biohazard.
Snap Cap Microtube properties
Available as sterile or non-sterile, polypropylene microtubes can also feature low binding properties to reduce protein and nucleic acid loss and hence better sample recovery.
- Can withstand forces up to max. RCF 30,000xg
- Are available sterile or non-sterile
- Are available with low binding properties, reducing protein and nucleic acid losses during centrifugations
- Available RNase/DNase, DNA-free and non-pyrogenic
- Typically made from durable autoclavable polypropylene for reusability and often graduated with a writing patch
- Available in a variety of colors, including amber and black for light sensitive samples
- Tube bottom shapes include conical and skirted (self-standing)

Electron Microscopy Sciences MacroTubes™ with Snap-Caps, Assorted
The 5 ml MacroTubes thave all conveniences of standard 1.5 ml tubes but are scaled up for larger volumes. The attached cap provides a tight, leak proof seal from -86 deg C to +80 deg C and can be opened or closed with one hand. The tubes are made of maximum clarity, low-binding virgin polypropylene and are certified RNase and DNase free.
Tubes are sized to be compatible with all Benchmark (USA) and standard German-designed equipment. The 16 mm tube diameter is identical to the diameter of 15 ml tubes, ensuring compatibility.
The potential contamination of pipettor shafts is greatly reduced because the 56 mm total tube length (vs. 120 mm for 15 ml tubes) is short enough for standard 1 ml or 5 ml tips to reach the tube's conical bottom. Feature dual graduations at every 0.2 ml and 0.5 ml.

Electron Microscopy Sciences Five-O™ 5ml Tubes Attchd Screw Caps, Sterile
Our new 5 ml Five-O screw cap tubes are made of maximim clarity, low-binding virgin polypropylene and are certified RNase and DNase 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. Screw cap tubes are supplied with 20 mm OD caps that seal smoothly and completely with a single 360 degree turn.
Useful from -86 deg C to 100 deg C, they are a valuable resource for boiling and sample preservation at very low temperatures. The foam racks are similar to the packaging normally associated with 15 ml tubes (upright woth caps attached), but require about 60 percent less storage space. Feature dual graduations at every 0.2 ml and 0.5 ml.
Sterile: Sterile
