supply lines are co-located with rinse and
waste lines (Figure 5).
8. Don’t let particulates clog your
system — Along with the concern over
invalidating a test due to foreign particulate,
fluid systems also rely on clean flow paths.
Pumps, filters, valves, and microbore tubing
are at risk of becoming clogged by particulate that can originate from fluid system
components. It is important to review the
quality standards of fluid-handling component suppliers and to ensure that machining
burrs or other foreign particulates will not
contaminate fluid lines and wreak havoc on
instrument components downstream.
9. Install cost-effective level sensing
for bulk fluids — Detecting fluid levels in
bulk solutions and waste containers is essen-
tial to avoid downtime and extra operator
maintenance time. Float switches provide
cost-effective, single-point detection when
a bottle is full/empty or can be used in a
modular design to detect multiple critical
points in a bottle. Alternatively, many
systems use load cells or conductive
probes that provide continuous level
detection and more precise measure-
ments. For applications that require
level sensing capabilities but involve
particularly caustic media or are
sensitive to microbial contamination,
products like capacitance and optical sensors
can provide non-contact level sensing. These
products can be particularly valuable when
handling fluids with a tendency to produce
salt build up or bottles that are extra vulnera-
ble to damage from a user.
10. Seek help from supplier experts
— Have a fluid handling question? Ask
the experts at fluid handling component
companies for advice on common is-
sues, improving fluidics designs, or cus-
tomizing standard products for unique
applications. Suppliers usually employ
design engineers and application
specialists who can answer questions
and help design seamless fluid handling
solutions for specific instrument needs.
Meeting today’s and tomorrow’s market
demands for high-productivity, high-reli-ability IVD equipment will depend, in part,
on efficient, effective fluid handling systems.
Smart fluid handling component choices
such as technologically advanced fluid connectors will help equipment manufacturers
maximize instrument productivity and
reliability, and make IVD testing faster and
easier for labs and operators. MDT
