Easy Cleaning Of Biological Safety Fume Hood Black Epoxy Tabletop
1. Epoxy Resin Worktop Chemical Property
Testing method
After 24 hour exposure,exposed areas are washed with water,then a
detergent solution,finally with naphtha,then rinsed with distillde
water and dried with a cloth.Change in surface finish and function
shall be described by the following(1-5) ratings:
1) No Effect: No detectable change in the material surface.
2) Good: Clearly discernible change in color or gloss,but no
significant impairment of surface life or function.
3) Excellent: Slight detectable change in color or gloss,but no
change to the function or life of the work surface material.
4) Fair: Objectionable change in appearance due to surface
discoloration or etch,possiby resulting in deterioration of
function over an extended period.
5) Failure: Pitting, cratering or erosion of work surface
material,obvious and significant deterioration.
2. Product introduction
Classic epoxy resin fume hood bases provide a durable chemical
resistant worksurface for the harshest laboratory environment-the
fume hood.
The worksurface is surrounded by a 10mm integrally-molded
containment rim designed to ease clean- ups and prevent hood and
casework damage from large chemical spills.
Available for virtually every brand of fume hood cabinet
manufactured today,classic fume hood bases are seamlessly molded up
to 2489mm long.
