Lancaster Labs implements Midi Distillation for new phenol Method 420.4
With the Environmental Protection Agency’s approval of Method 420.4, Lancaster Laboratories’ Water Quality Department is replacing its macro distillation apparatus with the Midi-Dist for phenols in waste-water. The Midi is faster, smaller and provides clients greater capacity than its macro predessessor.

A more compact distillation apparatus, the Midi reduces the amount of laboratory counter space as well as the sample size needed. And ultimately the smaller sample size reduces the time necessary for combining, storing, and disposing of reagents.

Instrumental Water Quality Group, prepares phenol
samples for Method 420.4 analysis.
“We are able to complete phenol analyses in one-fourth the time,” says Erik Frederiksen, manager of the Water Quality Department. “We are actually distilling less waste-water to begin with, which simply takes less time to analyze. So not only does the Midi enable faster turnaround time, it allows greater capacity. And most importantly, the Midi provides our clients accurate analytical results.”

Some of the benefits the Midi Distillation Apparatus provides are:
90 percent reduction in sample size
Less sample collection and processing
90% reduction in reagents used
Reduces challenges with mixing, storing, handling and disposing of reagents
80 percent reduction in space required
Reduction in distillation time
