EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

University of Texas at Tyler Lab 3C: Purification of L-Lactate Dehydrogenase By Affinity Chromatography on Cibacron-Blue Sepharose David Alexander 10-15-2014 Dr. Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally

Nowadays most of the industries are normally using standardization and customization for their business. The standardization can be defined as formulation‚ publication‚ implementation of guidelines‚ and rules for common and repeated use. It uniform the methods‚ technical‚ skills‚ processes and criteria to let the process of a work become easier and faster. However‚ customization is different compare with standardization. The definition of customization is process the work according the needs of an

Title: Preparation and Standardization of a Sodium Hydroxide Solution Objective/Purpose: The objective of this experiment will be the standardization of sodium hydroxide using potassium hydrogen phthalate by the titration method. Introduction: The concentration of solutions can be reported in terms of molarity and normality. Molarity is equal to: HCL‚ HBR‚ H2SO4‚ HNO3 M = mol Solute (mol) (Monoprotic) (Diprotic) _______________ V(L)g solutions (L)

Synthesis of Benzoin Date of Experiment: 1-26-15 Chelsea Price Lab Partner: Joey Simmons Abstract: In this experiment‚ benzoin was synthesized from benzaldehyde‚ using thiamine hydrochloric acid as a catalyst. The thiamine HCl was deprotonated by sodium hydroxide and acted as a nucleophile to attack the benzaldehyde. A water-cooled condenser was used to heat the solution at reflux. Vacuum filtration was used to wash and dry the product. The benzoin product was recrystallized
