Ball-valve mechanisms in these
couplings protect against spills
Epsilon dry-disconnect couplings
(photo) are designed for use in critical
in-plant and chemical-transfer
applications in pharmaceutical manufacturing.
Examples of volatile, hazardous
or high-value pharmaceutical
compounds whose transfer can benefit
from the use of Epsilon disconnects
include dichloromethane, toluene,
ammonia and pharmaceutical
slurries. Epsilon products utilize ball
valves rather than poppets to facilitate
the opening and closing of the
coupling, which allows a convex ball
to seat with a concave ball when the
valve is opened, producing a straightthrough
flow path that creates no
areas where chemicals can nest. The
result is fluid transfer that experiences
no reduction in flowrate while virtually
eliminating the occurrence of product
spills when the coupling is disconnected.
A series of five independent
and redundant mechanical locks
also prevents the Epsilon coupling
from becoming accidentally disconnected,
which removes the threat of
unintentional spills and releases. Epsilon
couplings are constructed of
316 stainless steel or Hastelloy, and
are available in sizes ranging from ¾
to 3 in. - OPW Engineered Systems,

Clean fragile filters with
these ultrasonic systems
This line of ultrasonic cleaning systems
for filters range from tabletop to industrial-size
floor models, each of which
can provide a quick, thorough cleaning
to filters. Ultrasonic filter cleaning
is an economical alternative to cleaning
with high-pressure water sprays
or brushes, especially for metal and
plastic filters that are very susceptible
to damage. Cleaners are equipped
with ultrasonic generators operating at
frequencies that excite tank-mounted
transducers to create millions of microscopic
bubbles in the cleaning
solution. Bubbles implode on contact
with the filter to remove contaminants
from any surface immersed in the ultrasonic
cleaning solution. Depending
on the model, the cleaning system
may include timers, temperature con40
trollers
and sweep and degas options.
Rinse stations and drying stations
are also available. - Tovatech, LLC,

These mixers are now
available for higher capacities
This company has expanded its
most advanced planetary mixer
line, the PDDM (photo), to include
larger working capacities up to
750 gal. The PDDM is a multi-agitator
mixer featuring two planetary stirrer
blades and two high-speed disperser
shafts. Designed for highly viscous
and highly filled applications, the hybrid
system can quickly incorporate
large amounts of dry ingredients
into thick or sticky liquid, and apply
intense shear to achieve a smooth
and uniform consistency. The PDDM
is rated for vacuum operation up to
29.5 in. Hg and includes a jacketed
change-can vessel, sight and charge
ports on the cover and an automated
lift for raising or lowering the agitators.
The mixer is usually supplied
with a discharge system for fast and
convenient transfer of the finished
product. - Charles Ross and Son Co.,
Hauppauge, N.Y.

A new line of motion controllers
with programmable automation
This company's line of controllers for
ultrasonic direct-drive motors and positioning
stages offer responsiveness
for a range of user requirements, including
precision positioning and handling.
The small-footprint C-877.1U11
single-axis controller (photo) and lowcost
two-axis controller are among the
product line's offerings. Also available
is the new C-867.262 multi-phase
controller, which allows for extremely
smooth motion with velocities below
1 µm/s, a critical feature for microscopy
and surface nano-metrology. The
controllers are delivered with extensive
software packages, including dynamic
libraries for Windows and Linux operating
systems. In addition, a powerful
macro programming language is available
for automation tasks and standalone
operation. - Physik Instrumente
