Druck’s PACE5000 facilitates pressure resistance testing in contact lens packages

Druck’s PACE5000 modular pressure controller was selected due to its cost-effective control and multiple test program options

Druck's customer
Druck’s Customer is the largest eye care device company in the world, offering a
wide array of ophthalmic solutions including, eye drops, optic suspensions, lenses
and eye vitamins.

Druck’s customer's challenge
Lenses are medical devices worn directly on the cornea of the eye and are made
from materials such as glass or plastic, that are ground and polished or moulded
to a desired shape.
Prior to distribution to healthcare providers and consumers, the lenses are sterilized
and packaged in a sealed container.
As lenses are considered medical devices, the packaging is a significant part of the
contact lens manufacturing process to ensure that lenses remain sterile to ensure
the safety of wearers.
To determine the seal strength of the packaging, burst tests are conducted, which
involve pressurizing the package until it bursts and measuring the terminal pressure.
Druck’s customer required a full-automatic instrument for testing the internal pressure
resistance of the packaging and the seal strength of the packaging at the seal point.

Druck’s solution
After evaluating several tools, the customer selected Druck’s PACE 5000 modular
pressure controller due to its cost-effective control and multiple test program options.
Burst test is a brand new application for the PACE series designed primarily for
manufacturers of pressure rupture discs, other safety critical devices and medical
products where it is important to accurately measure the exact point at which the
elastic limit or point at which the device will rupture or burst will occur.

Accurate and precise measurement of this phenomenon
enables scalable process improvement in the manufacture
of these devices, improved safety in applications where
safety is critical and improved quality of life in medical
applications.

Druck's added value
The introduction of Druck's PACE 5000 modular pressure
controller provided the following benefits:
