13 2 Using Physical Methods to Control Microorganisms

Common control methods include the application of high temperatures radiation filtration and desiccation (drying) among others Many of these methods nonspecifically kill cells by disrupting membranes changing membrane permeability or damaging proteins and nucleic acids by denaturation degradation or chemical modification

New Method for Monitoring the Process of Freeze Drying of

A miniature resistance thermometer was placed in the capacitive sensor to measure the temperature of the dried biological material Before drying the trays with the vials were placed in the refrigerator where the biological materials were frozen to about −40C The drying of the material was carried out in a TG-50 freeze dryer

Sterilizing Practices

Cleaning reduces the bioburden and removes foreign material (i e organic residue and inorganic salts) that interferes with the sterilization process by acting as a barrier to the sterilization agent 179 426 457 911 912 Surgical instruments are generally presoaked or prerinsed to prevent drying of blood and tissue

SEM Imaging of Biological Samples

For rigid biological materials such as the collagen-hydroxyapatite tissue scaffold used in this demonstration the sample is dried over a period of several days under high vacuum Finally since typical SEM imaging requires a conductive surface biological samples are often sputter coated with a thin layer of metal prior to imaging

Modeling of batch dryers for shrinkable biological materials

Design of dryers for biological materials is a complex problem since in order to solve the model equations foodstuff physicochemical and equilibrium properties and drying kinetics should be included as a function of water content and operating variables Shrinkage of biological materials under dehydration must also be taken into account when the macroscopic balances in the bed of drying

How to Set Up Your Own DIY Bio Lab

Apr 11 2017To manipulate small but very accurate amounts of liquids you will also need a set of adjustable pipettes Cheap Chinese pipettes can be bought from The ODIN and a few other places for around $40 a piece — you will want at least two or three different sizes to transfer anything from single-digit microliter droplets to several milliliters Other smaller items you will
