BenchLineDilutions and molarity
Plan single-step and serial dilutions, calculate molarity, and determine required reagent mass.
Official iPhone app
BenchLine Lab Utility
BenchLine Lab Utility is the official iPhone app from bench-line.com. It is a focused, offline-first laboratory calculator for trained users performing routine bench calculations, standards plate planning, saved workflow reuse, and calculation-support exports.
Formula-backed routine laboratory calculations
The BenchLine app supports dilution calculations, C1V1 calculations, serial dilution planning, 96-well standards and blank plans, report export, molarity and required-mass calculations, buffer preparation, laboratory unit conversion, and RPM/RCF centrifuge conversion. Inputs, assumptions, warnings, and formula references remain visible where they matter.
Standards plates
Plan standards and blanks from source stock through preparation volumes and 96-well allocation.
Report export
Create calculation-support TXT, PDF, JSON, and selected CSV exports with assumptions and warnings.
Preparation workflows
Prepare common buffers and review reagent-form choices, method notes, warnings, and assumptions.
Conversion tools
Convert common laboratory units and move between RPM and RCF using rotor radius.
Local saved work
Save presets and calculation history on the device without an account or cloud calculation-history sync.
Offline-first privacy
Core workflows work offline. BenchLine does not require an account and does not include advertising or analytics SDKs. Presets, history, settings, active sessions, pipette profiles, and rotor profiles are stored locally on the device.
BenchLine is not a lab notebook, ELN, LIMS, protocol system, diagnostic tool, medical device, or replacement for SOPs and professional judgment.
