Fisherbrand 8-Tube Strip with Caps 0.25 ml PP Pack of 250 Strips

Fisherbrand 14-230-215 8-Strip PCR Tubes with Flat Caps – 0.2 mL, Polypropylene

The Fisherbrand 14-230-215 (also listed as 14230215) is an 8-well PCR tube strip engineered for optimal thermal transfer during polymerase chain reaction (PCR) and real-time qPCR applications. Manufactured from premium, virgin polypropylene, these natural-colored strips feature an ultra-thin wall design that ensures rapid and precise temperature equilibration across the entire sample block. Each strip of eight tubes includes a corresponding strip of flat caps, providing a secure, leak-proof seal to completely prevent sample evaporation and cross-contamination during aggressive thermal cycling. Designed to fit standard 0.2 mL 96-well V-bottom thermal cyclers, these strips offer a nominal capacity of 0.2 mL with a maximum volume of 0.25 mL when fully capped.

Technical Performance and Design

• Thin-Wall Architecture: The ultra-thin, uniform wall thickness facilitates maximal heat transfer between the thermal cycler block and the sample, directly improving reaction efficiency and reducing overall cycle times.

• Secure Flat Caps: The included flat cap strips form a robust, tight seal that actively resists popping open under high-temperature denaturation steps, protecting the integrity of the reaction volume.

• Modular Flexibility: The linked 8-tube strips can be easily cut into smaller sections or individual tubes, allowing researchers to run low-throughput assays without wasting consumable materials.

• Certified Biological Purity: Cleanroom manufactured and strictly certified to be free of detectable RNase, DNase, Human DNA, and endotoxins, ensuring zero background interference in sensitive nucleic acid amplifications.

Key Benefits & Applications

• Standard & Real-Time PCR: The flat cap geometry and natural optical clarity allow for reliable fluorescent signal transmission during standard endpoint or quantitative PCR (qPCR) assays.

• Enzymatic Reactions: An ideal vessel for restriction digests, reverse transcription, and ligation reactions that require strict, programmed temperature control.

• Long-Term Storage: The resilient polypropylene construction securely handles sub-zero freezing (-20°C to -80°C) for the archiving of synthesized cDNA or amplified amplicons.

• Reagent Conservation: The conical V-bottom concentrates the sample matrix, allowing researchers to easily recover minute volumes down to 5 µL after the reaction is complete.
