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)

Alkali Scientific ASI™ 1.5mL Strip Tube, PP, Clear, 800/Cs, DNase, RNase & Pyrogen-Free
ASI™1.5ml Strip Tube, provided as strips of six microcentrifuge tubes physically connected in a row, is ideal for any large-scale experiments. The strips can be cut into individual tubes and are universally applicable to centrifugation. 1.5ml strip tube may restrictedly be compatible to rotors, depending on the types of rotors being used for centrifugation. Compatibility test, before proceeding experiment, is highly recommended. (Compatible to most 24-, 30-hole rotors, and few 18-hole rotors) ▪ Smooth opening and tight closing▪ Imprinted external graduations with marking area▪ Central part in cap enough to be penetrated by syringe needle▪ Autoclavable▪ Non – pyrogenic▪ Non – cytotoxic▪ DNase / RNase – free▪ Human DNA – free
MTC Bio 5mL Screw-cap MacroTube Vivid™, sterile, w/ vivid printed graduation w/ attached screw caps in foam racks, 500/cs
MTC Bio's MacroTube Vivid is the only 5mL screw-cap tube with printed graduations and marking area. 5mL Screw-Cap 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. Choose from gamma sterilized racked packaging with attached caps or non-sterile bulk packaging with separate caps. 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. 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
Research Products International Corp Micro-Centrifuge Tubes with Screw Caps, Ribbed, Conical Base, 1.5ml, 500 per Case
