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)
Research Products International Corp GripSeal Screw Cap Tubes, 0.5ml Capacity, Free Standing, Assorted Color Caps, 500 per Case
Polypropylene micro-tubes supplied with unique GripSeal caps feature bright contrasting color stripes on a white cap. The color stripes provide a quick and easy method for coding samples. Integral TPE (thermal plastic elastomer) cap seals provide a leak proof fit and eliminate a separate O-ring. Both the tube and cap are DNase and RNase free, and can be autoclaved. Micro-tubes are natural color with graduations. Color striped caps are packaged in the following assortment of colors: green, orange, red, violet, yellow and blue.
Research Products International Corp Screw Cap Micro-Tubes, 1.5ml Capacity, Conical Bottom, 500 per Case
Ideal micro-tube for high speed centrifuging, autoclaving, boiling and freezer storage. Screw cap with O ring provides superior sealing during sample processing. Tubes manufactured from transparent polypropylene for clarity. Suitable for a wide range of temperatures - from -196°C to +121°C (not for immersion in liquid nitrogen). Uniform wall thickness withstands maximum G forces over 20,000g. Versatile and durable tube developed for secure use in multiple laboratory environments.
Certified free of RNase, DNase, DNA and PCR inhibitors
Active Motif Sonication Tubes / Caps, 1.5 ml polystyrene
Because polystyrene transfers sonic wave energy much more efficiently than polypropylene, Active Motif highly recommends that its Polystyrene Sonication Tubes be used with the Q8000R Sonicator. Use of polypropylene tubes in indirect sonication has been shown to reduce the extent to which the chromatin is sheared.
MTC Bio Cryogenic Vials, internally threaded caps with silicone O-ring, 3mL, sterile, printed graduations and marking area, self-standing star foot, 50-place locking rack included with each case, 10 resealable bags of 50 tubes, 500/cs
MTC Bio cryogenic vials are designed to hold, store and preserve biological materials for days, weeks, years, or decades. These thick-walled tubes are outfitted with silicone O-rings that allow them to maintain their seal at temperatures as low as -196°C. Sterilized by gamma irradiation, the tubes are packed in reasealable bags of 50 tubes (10 bags per case) and are sterilzied by gamma. The self-standing starfoot base mates perfectly with a FREE included rack so that one hand is all that is need to install and remove caps. RNase, DNase, pyrogen, & endotoxin free
