Dura i vs BenchLine Lab Utility

PV inverter monitoring APP to monitor PV plant and PV inverter meter/parameters, provide local/remote setting.

BenchLine turns routine laboratory calculations into practical, reusable bench plans. Built for scientists, technicians and other trained laboratory users, BenchLine brings dilution planning, standards preparation, molarity calculations, buffer preparation, centrifuge conversions and everyday laboratory unit conversions into one focused iPhone app. Instead of giving you only a number, BenchLine keeps the calculation context visible — including inputs, units, formulas, practical warnings and preparation steps — so you can understand, check and apply the result at the bench. PLAN DILUTIONS AND STANDARDS • Calculate single-step dilutions using C1V1 = C2V2 • Build multi-step serial dilution plans • Plan standards for tube or plate workflows • Account for replicate volume and dead volume • Identify impractically small transfer volumes • Use practical transfer-volume rounding where appropriate • Keep the concentration series and preparation plan together PREPARE STOCKS AND SOLUTIONS • Calculate reagent mass from target molarity • Calculate molarity from a known mass • Convert between molar and mass concentration using molecular weight • Prepare common laboratory buffers • Select relevant reagent, salt and hydrate forms where supported • View preparation steps and scientific limitations alongside the result CHECK ROUTINE LAB CALCULATIONS • Convert laboratory volume, mass and concentration units • Convert temperature, time and length • Convert between RPM and relative centrifugal force using rotor radius • Keep molecular weight and equipment-specific inputs explicit SAVE AND REUSE YOUR WORK • Save frequently used calculation setups • Pin important presets • Reopen previous calculations • Review recent calculation history • Resume active work after leaving the app • Copy calculation results for use in your own laboratory documentation TRANSPARENT BY DESIGN BenchLine is designed to keep scientific calculations inspectable. Where relevant, results include: • Entered conditions • Units • Formula relationships • Calculation working • Assumptions • Practical warnings • Preparation guidance OFFLINE-FIRST AND PRIVATE Core BenchLine calculations work without an internet connection. • No account required • No advertising • No analytics or behavioural tracking • No cloud calculation history • Presets, history and settings remain on your device BUILT FOR THE LAB BenchLine is intended as a focused calculation and preparation utility rather than a replacement for laboratory procedures, instrument documentation or professional judgement. Always verify calculations and preparation methods against the exact reagent form, manufacturer documentation, calibrated equipment, local SOPs and your laboratory’s approved procedures. BenchLine is intended for trained laboratory users. It is not intended for clinical diagnosis, treatment decisions, medication dosing, patient management or other medical-device use. One purchase. No subscription. No ads. Just practical laboratory calculation support when you need it.
