  1. How to Clean Surgical Instruments Using an Ultrasonic Cleaner
    March 13, 2019
    Prior to sterilizing surgical instruments, it is a good idea to make sure you have cleaned them to remove blood, tissue and all other organic material.  If soiled materials dries or is baked onto the instruments, it will interfere with microbial inaction and can compromise the sterilization process. Cleaning is the removal of foreign material (e.g., soil and organic material) from objects and is normally accomplished using water with detergents or enzymatic products. The most common type of mechanical automatic cleaner is the ultrasonic cleaner. Ultrasonic cleaners are used in conjunction with detergents and enzymatic cleaners.  Ultrasonic cleaning removes particulates by cavitation (bubbles) and implosion. Waves of acoustic energy are transmitted in aqueous solutions and disrupt the bonds that hold particulate m

    The proper care and handling of your valuable surgical instruments will improve their longevity and function. Choose a protocol appropriate for your environment from the cleaning techniques below. See the videos here. RINSING Immediately after use, rinse instruments under warm or cool running water to remove all blood, body fluids and tissue. Dried soils may damage the instrument surface and make cleaning very difficult. Do not use hot water as this will coagulate proteinous substances. CLEANING TECHNIQUES Time, temperature, and agitation play important roles in the cleaning process. Time — the efficiency of cleaning chemicals is often time dependant Temperature — higher temperature cleaning solutions result in better cleaning Agitation — whether manual or ultrasonic, it is helpful in loo

    April 25, 2013
    WPI sells a new line of quality borosilicate glassware for laboratories. This article includes information on caring for your glassware. CAUTION: Soda lime glass is a softer glass and should not be used for laboratory purposes,because it cannot endure the temperature or pressure changes of borosilicate glass, and it should not be autoclaved at the high temperatures. Most bottles are made of soda lime glass.This article deals with borosilicate glass. Do not mix soda lime glass with borosilicate glass in racks when you are cleaning or autoclaving.  New Glassware New glassware is usually a little alkaline. After inspecting it for clips and cracks, wash the glass in warm, soapy water and then soak it in a solution of 1% HCl or HNO3 for a short period of time. Wash the glassware again and
