Lab Timer Workflow for PCR and Thermo-Cycling

Use a lab timer to stay on schedule during PCR, qPCR, and other thermo-cycling runs without missing steps.

PCR and qPCR runs follow a fixed pattern: denaturation, annealing, extension, repeat. A single mistake in timing or in the cycle count can waste samples and time. A lab timer that mirrors your program helps you stay on schedule.

Why a dedicated lab timer helps

  • Cycle awareness: You see at a glance which phase you’re in and how long is left.
  • Less mental load: No need to watch the cycler display every few seconds.
  • Multi-sample runs: One timer set per step works for all wells; you focus on pipetting and moving plates.

Setting it up in Lab Laps

  1. New project — e.g. “qPCR SYBR 2-step”.
  2. One step per cycle stage — e.g. “Denaturation 10s”, “Annealing 30s”, “Extension 45s”. Add a final “Hold” step if you use one.
  3. One timer per stage — Match the durations to your cycler program.
  4. Sync timers — Turn on timer sync so the same timers apply to every step. As the machine moves through the program, your Lab Laps view matches it step by step.

Optional: groups for ramp and hold

If your protocol has a “Ramp” or “Hold 4°C” block, add a group (e.g. “Initial denature + hold”) and put those steps inside. Use the main steps for the repeating cycles.


Lab Laps supports multi-step protocols, timer sync, and autosave. Try it on your next PCR run.
