A4-PCR8P （19201165）
PCR strip rotors are a small but decisive component in plate-based molecular workflows. The A4-PCR8P lists a fixed combination of speed, RCF, and tube capacity that buyers should check against their existing protocol.
The A4-PCR8P (Cat. No. 19201165) is a centrifuge rotor, not a full instrument. It is listed with a maximum speed of 7000 rpm and a maximum relative centrifugal force of 2680×g, figures that define the upper operating envelope rather than a recommended running condition.
Capacity is stated two ways: 0.2 mL×32 PCR tubes, or 0.2 mL×4 PCR 8-strips. Both describe the same nominal 32-position footprint, but the strip format is what matters for labs running eight-tube columns during setup, spin-down, and short plate transfers.
The rotor material is given as high-strength plastic. That constrains the conversation: plastic rotors are generally lighter and cheaper than aluminium equivalents, and their service life and chemical tolerance depend on the specific polymer, which the listing does not name.
Nothing in the source identifies the centrifuge model, rotor lock or mounting interface, lid requirement, or approved temperature range. These are the details a buyer needs before treating the rotor as a drop-in part for an existing machine.
Documentation is the other open item. A rotor used near 2680×g should come with a stated maximum rating, inspection interval, and material specification so labs can log its service history and replace it on schedule rather than on failure.
For procurement, the practical move is to confirm rotor-to-centrifuge compatibility, tube and strip fit, and available certification or test records before ordering. The listed parameters describe a narrow, specific part, not a universal accessory.
A rotor’s usefulness is decided by the instrument it fits and the traceability behind it, not by its headline speed. Those two points are outside what this listing establishes.
Why it matters:
Rotor specifications age with use, and a plastic rotor carrying PCR strips at up to 2680×g needs a documented rating and replacement schedule. Buyers should obtain the missing compatibility and material details before purchase.
