INK OPTIONS

• Waterproof Ink
  
  The TubeWriter uses the same waterproof ink you are accustomed to. The printing wil not come off in boiling water baths, liquid nitrogen, or your freezer.
  

• Alcohol-proof Ink
  
  By switching the writing instrument using the TubeWriter's SurLock system, you can write with alcoholproof ink on your tubes and slides.  This is the perfect choice for users working in environments with light organics and alcohols.   
  
  
• Colors
  
  The SurLock system also includes a variety of writing instrument colors that can be easily be swapped in and out using the specially SurLock molded plastic sleeves.
