FILTRATION: For multiple sample (3 and 6 place) sterility testing of antibiotics and pharmaceuticals
by bacteria retentive method and for routine microbiological filtrations. Because of the potentially
large volumes of liquid used with vacuum manifolds, a liquid pre-trap is recommended. |

Continuous
Self-Cleaning Pumps for Saturated Vapors
A new, patent-pending self-cleaning diaphragm pump designed specifically to
reduce process time for vacuum ovens, vacuum concentrators and even rotory evaporators.
Unlike other self-cleaning pumps that cycle at the end of the vacuum
process, KNF's PowerDry operates throughout the process, when you need it
most.

NOTES: Standard continuous performance
ratings listed on this KNF website and on KNF datasheets are
based on technical data and test results of nominal units at
sea level, measured with an ambient temperature of 70°F
(21°C), and nominal
electrical supply as listed above, and are for reference only.Multiple-head
models, different performance models, cost-effective OEM modifications, and
a variety of motor options and different materials of construction are also
available. Certified drawings are available upon request. Specifications subject
to change without notice. You should always check corrosion resistance charts
for compatibility with the medium you intend to pump.
