Sectioning a tissue can use either the micro tome knife or the razor blade as the cutting blade. [4] The micro tome knife is used for handling sectioning. It is necessary to use a micro tome knife when preparing sections less than 1/1000 micrometers. [29] When using such a knife, the operators must be extremely careful.
The optimal angle depends upon the knife geometry, the cut speed and many other parameters. If the angle is adjusted to zero, the knife cut can often become erratic, and a new location of the knife must be used to smooth this out. If the angle is too large, the sample can crumple and the knife can induce periodic thickness variations in the cut.
While proper procedures and training can minimize the chances of an accidental fire, laboratory workers should still be prepared to deal with a fire emergency should it occur. In dealing with a laboratory fire, all containers of infectious materials should be placed into autoclaves, incubators, refrigerators, or freezers for containment. [22]
Brain knife: to cleanly cut the brain Rib shears: to cut through the ribs while opening the chest [3] Dissecting scissors: for sharp cutting Speculum: for vaginal and rectal examinations Non-absorbable sutures: usually nylon to close the body cavities and sutures it Postmortem needles: large thick needles for suturing the skin after
In natural and social science research, a protocol is most commonly a predefined procedural method in the design and implementation of an experiment.Protocols are written whenever it is desirable to standardize a laboratory method to ensure successful replication of results by others in the same laboratory or by other laboratories.

The CPT code revisions in 2013 were part of a periodic five-year review of codes. Some psychotherapy codes changed numbers, for example 90806 changed to 90834 for individual psychotherapy of a similar duration. Add-on codes were created for the complexity of communication about procedures.
Annex I of the Directive incorporates OECD Revised Guides for Compliance Monitoring Procedures for GLP, along with OECD Guidance for the Conduct of Test Facility Inspections and Study Audits. It ensures compliance with these guidelines during laboratory inspections and study audits. This directive replaced Directive 88/320/EEC as of 11 March 2004.
