Common laboratory procedures

Avoid direct contact with any hazardous material. Know the types of protective equipment required while using any chemical.

Common laboratory procedures

As implied above, the initiative and further procedure for the preparation, implementation and management of the documents is a procedure in itself which should be described. These SOPs should at least mention: It should be established and recorded who is responsible for the proper distribution of the documents, the filing and administration e.

Finally, it should be indicated how frequently a valid SOP should be periodically evaluated usually 2 years and by whom.


Only officially issued copies may be used, only then the use of the proper instruction is guaranteed. In the laboratory the procedure for the preparation of a SOP should be as follows: In principle, the author is the person who will work with the SOP, but he or she should always keep in mind that the SOP needs to be understood by others.

Common laboratory procedures

The author requests a new Common laboratory procedures number from the SOP administrator or custodian which in smaller institutes or laboratories will often be the HoL, see 2.

The administrator verifies if the SOP already exists or is drafted. If the SOP does not exist yet, the title and author are entered into the registration system. Once the writing of a SOP is undertaken, the management must actively support this effort and allow authors adequate preparation time.

In case of execution procedures for investigations or protocols, the project leader or HoL could do the testing.

In this phase the wording of the SOP is fine-tuned.

Revisions of SOPs follow the same procedure. The make-up of the documents should meet a minimum number of requirements: Categories can be denoted with a letter or combination of letters, e. The first page, the title page, should mention: It is possible to record the authors centrally in a register ; f.

The necessary equipment, reagents including grade and other means should be detailed. A clear, unambiguous imperative description is given in a language mastered by the user. It is recommended to include criteria for the control of the described system during operation.

It is recommended to include a list of contents particularly if the SOP is lengthy. It is recommended to include a list of references. However, once the draft is made, with the use of word processors and a simple distribution scheme of persons and departments involved, the task can be considerably eased.

A model for a simple preparation and distribution scheme is given in Figure This is a relation matrix which can not only be used for the laboratory but for any department or a whole institute. In this matrix which can be given the status of a SOP can be indicated all persons or departments that are involved with the subject as well as the kind of their involvement.

This can be indicated in the scheme with an involvement code. Some of the most usual involvements are the number can be used as the code: Taking initiative for drafting 2.Written with laboratory technicians and restorative dentists in mind, the book is organized by case type, taking common case scenarios and devoting a separate chapter to each one in turn, demonstrating each step of the laboratory procedures required for the implant r-bridal.coms: 3.

Clinical and Laboratory Standards Institute document HAProcedures for the Handling and Processing of Blood Specimens for Common Laboratory Tests; Approved Guideline--Fourth Edition considers multiple variables that are involved in handling and processing blood specimens.

•Any hazardous chemical use which does not meet this definition is regulated under other standards. This includes other hazardous chemical use within a laboratory. Biomass Compositional Analysis Laboratory Procedures NREL develops laboratory analytical procedures (LAPs) for standard biomass analysis.

These procedures help scientists and analysts understand more about the chemical composition of raw biomass feedstocks and process intermediates for conversion to biofuels. Please post or circulate EH&S Office of Environment, Health & Safety For common laboratory equipment (e.g., ultracentrifuges), the manufacturer’s operations and maintenance manual may serve as, Describe procedures for handling potential emergencies related to this chemical or.

Laboratory gas burners produce various kinds of flames when different mixtures of gas and air are burned. The two most common models are the Bunsen burner and the Tirrell burner. Both have adjustable air vents;.
