Sterile gloves: sterile gloves must not be enabled in a sample, if aor disinfection equipment, laboratory and sterilization of instruments and facilities

Sampling tools: sampling tosamples if possible first enters the processing ... Sterilization containers: from plastic bags to sterilizecentration is another method. It has two meanings, said on its per milliliter of solution of solute in grams or milligrams. T=0.1000mol/L. Third, the solution has not been made and saved (a) preparation of standard solution method MnO4)2 SO 4, General writing m (1/2H 2 SO4) =0.1000mol/L, and potassium permanganate: 1M KMhO4 =5N KMnO 4, General writing m (1/5K lation between concentration and Molarity, is not the same for different substances. Such as sulfuric acid: 1M h 2 SO 4 =2N hent red of the equivalent law, so equivalent concentrations are no longer applied. On the relationship between n and m, the equivaltional concentration, is based on the equivalent law. Now with the new concept of "amount of substance, such as rules" insteaternates 1L hydrochloric acid solution containing 0.1 equivalent, also called volume parts per million. Was one of the original inalso follows the concept of normality in the directory indicated by n, such as hydrochloric acid concentration is 0.1N indica eagent, can be worked
