Microcentrifuge Tube
Product Code : EL-TT-10148
Quick answer: This is a polypropylene microcentrifuge tube available in the two standard small-volume capacities used in molecular biology and diagnostic work — 0.5 ml and 1.5 ml — sized to fit standard microcentrifuge rotors and racks.
Why 0.5ml and 1.5ml Are the Standard Microcentrifuge Sizes
These two capacities cover the great majority of small-volume sample handling in a molecular biology or diagnostic workflow: 0.5 ml tubes suit very small reaction volumes such as PCR setup steps or concentrated reagent aliquots, while 1.5 ml tubes are the general-purpose default for sample storage, extraction steps and routine bench work. Polypropylene construction resists most reagents and solvents used in nucleic acid and protein work, and both sizes are built to fit the standard microcentrifuge rotors, racks and float racks used across the industry, so a lab can stock both sizes without needing capacity-specific accessories beyond the tube itself.
Frequently Asked Questions
What capacities are available for this microcentrifuge tube?
It is available in 0.5 ml and 1.5 ml capacities, the two standard sizes used across most molecular biology and diagnostic workflows.
What is the difference in use between the 0.5ml and 1.5ml sizes?
The 0.5 ml size suits very small reaction volumes such as PCR setup or concentrated reagent aliquots, while the 1.5 ml size is the general-purpose default for sample storage, extraction steps and routine bench work.
Will this tube fit standard microcentrifuge rotors and racks?
Yes, both capacities are sized to standard microcentrifuge rotor and rack dimensions used across the industry, including the Float Rack and Microcentrifuge Tube Racks in this range.
