MicroBlock TM : Operation and Instruction Manual General Information
MicroBlock TM Safety Information
1. The Environmental Express MicroBlock should be set up and operated in a chemical fume hood with a face
velocity of not less than 100 CFM.
2. Wear appropriate Personal Protective Equipment (PPE) suitable for use with caustic and corrosive materials.
3. Do not operate the MicroBlock in the vicinity of combustible material.
4. Be certain the MicroBlock power cord is properly grounded by consulting your in-house electrician.
5. During operation the surfaces around the heater assembly will get HOT. Do not touch the outer surface.
6. Do not move the MicroBlock system while hot.
7. Do not attempt to operate the MicroBlock system over 190°C.
8. Allow the MicroBlock to cool for 20 minutes before removing glassware. Separation of the “hot” glassware
components could result in bumping, boil over, and/or spraying of hot corrosive/caustic materials.
9. Review Material Safety Data Sheets for all materials used or generated during the operation of the MicroBlock.
Avoid breathing any vapors that may come off of the MicroBlock system, they may be harmful or fatal.
10. Water and vacuum (if used) should be continued until the MicroBlock has cooled down to prevent boil over. The
electric cord should be kept plugged into its outlet until the unit has cooled down.
11. If boil over does occur during operation of the MicroBlock operation, immediately wipe the system down with
neutralizing solution, such as a mild solution of sodium bicarbonate.
12. Unplug the MicroBlock from the outlet prior to cleaning exterior surfaces. Wipe with damp sponge or towel after
each use, first with mild sodium bicarbonate or similar solution followed by Dl or distilled water. Avoid solutions
on or near the controls.
13. If a MicroBlock system with a vacuum is used, install an excess gas trap in the vacuum line to remove excess
vapors.
14. Use micro-porous boiling chips in each distillation flask to prevent bumping.
15. It is recommended that a tray or petri dishes be used under the drain outlets to catch any spills from boil over
and/or breakage.
