We have made numerous improvements in our new Optimum™ line of dispensing
components. We continue to use the same basic materials in their construction so you can
be assured of the same outstanding level of chemical compatibility you enjoy today.
The new Optimum pistons are manufactured from the same material as Ultra™ pistons.
The colorants and their concentrations in the beige, white, red and blue pistons are the
same for both the Optimum and Ultra product lines.
The new barrels are manufactured from a proprietary blend of polypropylene resins that
provide an excellent combination of clarity, toughness and chemical compatibility. The
resin blend used in the new Optimum™ line will continue to provide the same level of
chemical compatibility as our existing Ultra™ line.
components, produced and distributed by EFD, Inc. are in compliance with European
Directive 2002/95/EC (Restriction of Hazardous Substances), regarding the content of the
six identified restricted hazardous substances (mercury 0.1%, cadmium 0.01%, lead
0.1%, hexavalent chromium 0.1%, polybrominated biphenyls (PBB) 0.1% and
polybrominated diphenyl ethers (PBDE) 0.1%).
