SDLABIO PCR Tubes

SDLABIO PCR tubes are disposable consumable designed for polymerase chain reaction (PCR). Made from highly transparent polypropylene (PP), the tube offers excellent heat resistance and chemical stability, capable of withstanding the rapid temperature fluctuations exceeding 100°C during PCR cycling. PCR tubes are widely used in molecular biology, genetic testing, medical diagnostics, and scientific research.

Feature of PCR reaction tube​

  • High-quality material: Made of high-purity polypropylene (PP), free of DNase, RNase, and pyrogen contamination.
  • Various sizes: Common volumes are pcr tubes 0.2 ml​ and 0.5 ml pcr tubes, adapting to different experimental needs.
  • Ultra-thin tube wall design, smooth tube wall, good heat conductivity. Tube cover has good sealing and opens smoothly.
  • High quality and low price: can be used as a substitute for Eppendorf PCR tubes.
  • Sealed design: Available with either a flip-top or flat cap to prevent evaporation and leakage of the reaction system.
  • Compatible: Compatible with most standard PCR instruments and real-time PCR instruments.
  • High-temperature cycling resistance: Withstands freezing at -80°C and autoclaving at 121°C, suitable for various PCR experimental conditions.

FAQ of polypropylene PCR tubes

What is the maximum volume of pcr tubes?

PCR tubes come in different volumes depending on the experiment scale and thermocycler compatibility. The most common sizes are:

  • 0.1 mL – typically used for fast or low-volume PCR reactions, often in specialized low-profile thermocyclers.
  • 0.2 ml pcr tubes – the standard PCR tube volume, widely compatible with most PCR and qPCR instruments.

  • pcr tubes 0.5 ml – less common, but available for certain applications that need larger reaction volumes.

So, the maximum volume of standard PCR tubes is usually 0.5 mL.
For larger reactions, scientists often use PCR-compatible microcentrifuge tubes (1.5–2.0 mL) instead of classic PCR tubes.

  • Thin-walled design

PCR tubes have very thin plastic walls (usually polypropylene), which ensures rapid and uniform heat transfer between the thermocycler block and the reaction mixture.

This is critical for accurate denaturation, annealing, and extension steps.

  • Domed or flat caps

Domed caps reduce condensation and improve thermal efficiency.

Flat caps are better for qPCR (when optical detection is needed) and when sealing with adhesive films in strip/plate formats.

  • Precise fit in thermal cyclers

PCR tubes are designed to snugly fit the wells of thermocycler blocks, minimizing air gaps that could cause uneven heating.

Available as individual tubes, strips (8 or 12 strip tubes), or plates (96/384 wells) for high-throughput workflows.

  • Low-retention, nuclease-free plastic

Made of high-quality polypropylene that resists protein and DNA sticking, and free of RNase/DNase, ensuring reaction integrity.

  • Optical clarity

qPCR-compatible tubes are made with ultra-clear caps/walls for accurate fluorescence detection during real-time PCR.

Individual PCR test tubes are suitable for small-scale sample reactions or individual experiments, while 8 strip pcr tubes are more suitable for high-throughput experiments and processing large batches of samples.

Reuse is not recommended. Tubes PCR​ are disposable, and reuse may lead to cross-contamination or inaccurate results.
