LABOPORT® Vacuum Pumps
The Perfect Companion for Rotary
Evaporators, Gel Dryers, Distillers & Vacuum Ovens
Get the best, get a LABOPORT®
For vacuum applications where a
variety of vapors are encountered, consider KNF’s premium pumps made
from Teflon® and Kalrez® resins. These attractive pumps handle even the
most aggressive corrosives without the need for messy protective devices.
With KNF pumps, only thick, solid heads made of Teflon® resin and sturdy
valves of Kalrez® resin come in contact with the vapor stream—the best
corrosion-resistant materials available today!

Deepest vacuum available in a
maintenance-free dry pump - 1.5 Torr
 |
Ideal for the processing of heat sensitive
samples where the application of heat to enhance evaporation cannot be
used, or for evaporating high boiling point solvents.

| LABOPORT® pumps are designed
to keep your lab up and running! With LABOPORT®,
there’s no need to worry about corrosive condensate droplets damaging
valve parts and degrading performance. Never again be delayed by expensive
off-site pump repairs. Here's why:
Molded diaphragms and heads of Teflon®
resin KNF builds their pumps with solid Teflon® resin for
the ultimate protection against aggressive vapors. KNF pioneered use of
Teflon® resin in the manufacture of their diaphragm pumps. This material
is now used in all LABOPORT® pumps. There is no peeling or blistering, as
can happen over time with coated heads. Also, there is no metal clamping
disk, a source of leaks and corrosion with traditional diaphragm pumps.
Multi-Port valves of Kalrez® resin
This valve is an exciting breakthrough in diaphragm pump design, and is a
patented product from KNF’s worldwide R&D center. The tough,
circular valve disk made of Kalrez® resin spans several smaller holes
instead of one large hole, and can easily withstand punishment created by
pumping liquid droplets. Older, less efficient flapper-type valves can be
easily damaged by liquids, necessitating expensive repairs, inconvenient
delays and equipment downtime. |
NOTE: Standard continuous performance ratings are based on
technical data and test results of nominal units at sea level with an
ambient temperature of 70° F (21° C) and nominal electrical supply as
listed above. Teflon® and Kalrez® are registered trademarks of DuPont.

for compatibility with the chemicals used in your lab.
