Preparing Specimens

Small specimens

  • Place specimen in small jar filled 1/2 to 3/4 full with formalin​ (10% NBF)
  • Ideal amount of formalin is 10:1
    • 10 times the volume of formalin as the sample
  • Small samples are ready for shipping immediately. Formalin fixation occurs at a rate of 1 mm per hr for the first hr, and then slows to about 1 mm every 3 hours. A 1 cm thick tissue will fix completely in 12 hours in the correct volume of formalin.
  • Specimens should be no larger than 2-3 cm
  • Ensure the formalin jar is filled 1/2 to 3/4 full

Large specimens​​

  • Spleen, liver lobe etc​
  • Fix in 10% NBF; it is a good idea to obtain a supply for large samples
  • 10% NBF at 10:1 formalin: tissue 
  • Blood filled specimens fix more slowly
  • In general over night fixation is adequate for shipping purposes; in general large specimens take 1-2 weeks to fix completely
  • Include a small amount of formalin in the primary container with the sample


  • Makes sure all lids are leak proof​
  • Enclose cytology slides in air tight packaging if submitted with biopsies, because formalin vapors can cause artifacts in cytology smears.
