Chemistry-/LifeScience-pocket calculator, Chemcode®, L 136 x W 110 x D 14 mm

Features:

• Keyboard with periodic table and numerical keyboard
• Buttons for DNA (A, T, G, C) and RNA (A, U, G, C) nucleotides
• Two-line display with scroll function
• Functions for scientific calculations

Stoichiometric functions

Displays: molar mass, ideal gas volumes, mass to be weighed in g, amount of substance in molesCalculates: molecular formulas, proportion of individual elements or element groups in % or g, mass of substances in g. Converts from molar concentration (mol/l; molarity) into mass concentration (g/l) and vice versa, mass-% into molarity. When diluting, determines the volumes to be input in litres and calculates the amount of substance in mmol when performing titrations.

Molecular biological functions for the PCR®

Displays: protein codes, %-proportion of guanine and cytosine, molar mass of the nucleotide sequence and protein sequence, amount of substance in nmol, optical density, amount of substance in a DNA segment in ng, melting temperature of the oligonucleotide.

Lexical functions:

• Conversion between °C, F and Kelvin
• Recalls different constants (Avogadro, Faraday, etc.)
• Functions for recalling chemical, physical and biological characteristics of elements and other information such as melting point, boiling point, electro-negativity, year of discovery, etc.
