ULTRAPEN™ PTBTx™ vs Solution Dilution Calculator

REQUIRED EQUIPMENT: ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Myron L® Company ULTRAPEN PTBTX (First Generation Ultrapen; Lot Code Y1930 and earlier) Models: PTBT1; PTBT2 or PTBT3 DOES NOT WORK with Myron L® Company ULTRAPEN PTBTx2 (Second Generation; Lot Code Y1931 and later). INTRODUCTION ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ The ULTRAPEN PTBTX App is a GUI and communication application that, when paired with one of Myron L® Company's First generation ULTRAPEN pocket testers, converts your iOS device into an accurate, reliable, fast and simple to use measurement and data storage device to use in diverse water quality applications. ADVANCED FEATURES INCLUDE: ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ - Wireless communication between the tester and your iOS device means no bothersome wires to interfere with quickly moving from sample to sample and the paired mobile device can be held safely away from the liquid samples being measured. - Intuitive GUI design for easily pairing, calibrating, measuring and recording measurements in the App on-board database. - The database can be sorted, filtered and exported via your devices email App as either .xls; .xlsx, .csv formatted attachments - Automatic records made of every calibration performed on each PTBTX2 pocket tester. WORKS WITH ULTRAPENX2 POCKET TESTERS ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ULTRAPEN PTBT1 (First Generation) - Measures Conductivity, Total Dissolved Solids (TDS), Salinity, and Temperature. ULTRAPEN PTBT2 (First Generation) - Measures pH and Temperature. Can be calibrated using 1, 2, and 3 point calibration options. ULTRAPEN PTBT3 (First Generation) - Measures Oxidation Reduction Potential (ORP) and Temperature. Can be calibrated to one of three different calibration points (80 mV, 260 mV, or 470 mV). The PTBT2 and the PTBT3 Include a sample and hold mode as well as a live measurements mode. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Myron L® is a registered trademark of the Myron L® Company, 2450 Impala Drive, Carlsbad CA, 92010-7226 Bluetooth® is a registered trademark of Bluetooth SIG

The Solution Dilution Calculator calculates the volume of stock concentrate needed to achieve a specified volume and concentration. It uses the formula: C₁V₁ = C₂V₂ where: C₁ = Initial concentration (stock solution) V₁ = Volume to be removed (aliquot) from the stock solution C₂ = Final concentration of the diluted solution V₂ = Final volume of the diluted solution (after dilution with the solvent) Designed for both teaching and research laboratories, this calculator can be used for dilution calculations with solutions expressed in mass per volume (e.g., g/L, mg/mL) or weight per volume (e.g., % w/v) concentration units. Example Dilution Calculation: Question: What volume of a 10 mM stock solution is required to prepare 20 mL of a 50 μM solution? Solution: Using the equation C₁V₁ = C₂V₂, where: C₁ = 10 mM C₂ = 50 μM V₂ = 20 mL V₁ = Unknown Steps: Enter 10 into the Concentration (start) box and select millimolar (mM). Enter 50 into the Concentration (final) box and select micromolar (μM). Enter 20 into the Volume (final) box and select milliliters (mL). The result, 100 microliters (0.1 mL), will appear automatically. Thank you for your support! Stay tuned for more updates.
