Lab Stopwatch
About the Lab Stopwatch
Laboratory work is a sequence of timed steps - add reagent, start stir, read at five minutes, quench - and missing a step window ruins the trial more often than wrong math. A lab stopwatch laps each protocol milestone on one elapsed session so the notebook narrative matches what actually happened. Teaching labs use projected elapsed clocks so thirty students know when to read spectrophotometer values together. R and D chemists lap parallel trials on the bench, export CSV rows into the ELN, and compare incubation segments across batches.
How to use it
- Read the protocol and mark lap points before touching reagents.
- Start at step one or at reaction zero as defined.
- Lap at each timed hold, reading, or addition boundary.
- Export or copy laps into the lab notebook immediately.
- Tag trials with batch IDs in notes, not sensitive identifiers.
Good to know
The stopwatch counts while this tab is open. A slept tab can pause or jump. For a race result you may need to keep the phone unlocked in your hand.
