Why Scientists Are Switching
Same Films You Trust.
Better Value All Around.
Premium performance at up to 50% savings — plus quality assurance the big brands don't offer.
PCRSeal films deliver the same optical clarity, seal integrity, and thermal performance as the brands you've been ordering for years. Compatible with every major qPCR platform. Drop-in compatible with your existing protocols — order a sample pack and verify on your platform.
The difference? Every lot is functionally tested — not just process-certified — and your Certificate of Analysis is available on demand. No emails. No waiting. No compromise.
That's not an upgrade — it's the new standard. Premium quality without compromise.
1
Ct Value: 10.72 (PCRSeal)
Ct (cycle threshold) measures how quickly the instrument detects your DNA target. Lower numbers mean faster, more sensitive detection. PCRSeal scores 10.72.
2
Ct Value: 10.76 (Leading Brand)
The leading brand scores 10.76 — a difference of just 0.04 cycles. That's well within normal variation. The performance is statistically equivalent.

Tight Curves = Reliable Results
Each line represents an independent test replicate. The tighter the grouping, the more consistent and reproducible the film performs — run after run, well after well.

COMPARE
Same Instrument. Same Result.
Both films were tested head-to-head on the same Applied Biosystems® StepOne Plus™ 96-well system — same protocol, same conditions. A 0.04 Ct difference is statistically indistinguishable. You get equivalent sensitivity and reproducibility at up to 50% less cost.
