11.2.2 PC centrifuge tube cleaning PC material has relatively low chemical stability to alkaline solvent, therefore use of cleaning agent with pH value of over 9 should be avoided. Some neutral cleaning agents still have pH value of over 9 after being diluted as recommended by the vendor, therefore use of cleaning agent with pH value of 7-9 is recommended. -
