Automating and Enclosing Bulk Fill Operations - The Way Forward?_SciLog SciPure FD System_Parker Bioscience FiltrationThe consequences of failure during downstream processing are severe. Following the Affinity Chromotography stage, the value of the product increases significantly at every step. A failure at the final bulk filling stage, therefore, could lead to the waste of millions of dollars’ worth of drug product.


It’s vital, therefore, to safeguard the bulk filling process. But traditional methods of conducting bulk fill operations have several disadvantages including:


1. Manual handling

This introduces the possibility of human error to the bulk filling process. It is also labour intensive, meaning that process operators need to divert their resources into this task.


2. Operator training

When bulk filling is carried out manually, investment must be made in operator training. This can be costly, both financially and in terms of the time dedicated to it by personnel.


3. Supply chain complexity

By using a range of components from several different suppliers in the bulk filling process, there is more potential for variation – and more time must be spent on sourcing and ordering suitable components.


4. Laminar air flow (LAF) maintenance and validation

In traditional bulk fill operations, laminar air flow must be maintained and validated to protect the products from contamination. This requires time and resources.


5. Shipping issues

At the shipping stage, poor handling of bottles – and the use of unsuitable containers – can lead to damage to products before they even arrive at their destination.


6. Non-standard operations and process variability

Traditional methods of bulk filling introduce variability into the process. If bulk filling operations aren’t standardized, they can be subject to a number of factors which can impact the final product. Factors such as different flow rates applied by different operators come into play.


The solution

Automating and enclosing bulk fill operations can address the challenges detailed above and increase safety for operators. Parker Bioscience Filtration has developed the SciLog® SciPure FD system as an automated and integrated single-use system for final bulk filtration, filter integrity testing and dispensing into final bulk product containers.


Here are some of the benefits:



This reduces the risk of human error from manual handling and allows operators’ resources to be spent on other tasks.



Standardizing operations means that training can be simplified and variations in the process can be eliminated.



Enclosing the process allows operators to process highly potent molecules and protects both the operators and the process. And, as the flow path is completely enclosed, both filtration and dispensing can be performed in areas of lower classification, eliminating the requirement for vertical laminar flow cabinets.


The SciLog® SciPure FD system

The SciLog® SciPure FD system benefits from innovative component selection based around material science studies, improved filling accuracy (+/-1%), and greater flexibility in the scale of filling (from 50ml samples to 20L).


The system features include a barcode reader for manifold tracking, reverse flow and purge options to maximize product recovery and fully programmable alarms and interlocks to product and process.



A validated shipping solution

Parker Bioscience Filtration has created a unique bottle design that offers manufacturers the confidence that bulk drug products will arrive at their final destinations without contamination.


Parker Bioscience Filtration drew on its extensive material science knowledge during the development of the bottle and material selection was based on an FMEA study. The bottle integrity has been validated down to -89˚C.


Parker Bioscience has also developed an anti-foaming device that eliminates foam and enables a higher filling speed.



The development of the SciLog® SciPure FD System is an example of the change in the vendor/end user relationship: by using a vendor such as Parker Bioscience Filtration, which can provide a complete solution, end users can increase their productivity and gain greater control and protection over their processes.

 In every manufacturing industry, machine safety is always a top priority. When operating in Europe, utilizing machinery and components with CE certification is the best way to ensure the reliability of the equipment that benefits both production and the operators who use the equipment. 

What is the Machinery Directive?
First published in 1989, the Machinery Directive was designed to provide freedom of movement across Europe for machinery and safety of workers in an effort to reduce injuries. 

In 2009, the Machinery Directive 2006/42/EC became law in Europe, and its primary role is to ensure common safety levels of machinery placed on the market and put into service. 

Today this directive lays down the foundation and regulatory basis for the harmonization of Essential Health and Safety requirements (EHSR) in the field of machinery. It is unified with CE requirements and covers almost 21 distinct EN Standards to guide machine builders on safety requirements and has worked to harmonize with other safety organizations. Ultimately becoming the foremost authority on where to go to design a safe piece of equipment globally.

Directive qualities
A unique quality of the Machinery Directive is its broad coverage for machinery design. The standards start at concept of design or designing out risk. The directive mandates a technical file be kept on the machine to show its inception and what risk avoidance was implemented to create a safer machine. 

Guidance is provided to the machinery builder in the form of EN standards which mandate a risk assessment be conducted on machinery. Finally, the directive includes information on disposal at end of life of machinery. While broad, the directives do a great job of ensuring safety is addressed at every level and even account for “unintended use of machinery” at the design stage.

Another interesting note is given that one of the primary purposes of the Machinery Directive is to ensure common safety, the directive does not mandate the use of safety rated products. It does clearly differentiate standard components used in a safety application versus those products built and intended as safety rated products.

Safety rated products are classified separately and are subjected to more rigorous requirements, testing and expectations for performance. 

The directive does state that common sense strategies be employed on machinery such as the use of e-stop buttons, the removal of air in a machine to protect from unexpected movement (where safe to do so) and the addition of technical measures where risk cannot be designed out. Additionally, to meet enhanced safety levels on machinery, redundancy and monitoring must be included in the controls of the machine EN ISO 13849-1 as well as validation of the system EN ISO 13849-2.

Some manufacturers offer safety rated components, such as Parker’s P33 series of safety exhaust valves, which meet the needs of the directive to remove air from machinery during either an e-stop or a faulted condition on the machine. 

Knowing that products now exist which incorporate the needs of the directive and provide an enhanced level of certified safety can bring peace of mind to machinery designers and the engineers responsible for enhanced and integrated safety on machine.

EMI Testing for Medical Devices - What you Need to Know, Parker Chomerics, HospitalNot long ago in hospitals and other critical care facilities, you were greeted with a large, ominous warning sign the moment you walked through the entrance doors to refrain from cell phone use due to possible medical equipment malfunction or interruption.

Today, patients and visitors are free to use mobile phones and devices without fear of interfering with medical equipment, but there’s still a long way to go to reduce electromagnetic emissions and electromagnetic compatibility (EMI/EMC) issues in medical devices.

Medical devices require complex analysis of the EMI/EMC regulations used for medical equipment and system certification. There are many new aspects that need to be addressed since medical devices are no longer used in just a hospital setting. With the increase of wearable medical tech, patients can theoretically be anywhere in the world. Therefore, EMI/EMC compliance testing needs to address the location of “end use” such as in the home healthcare environment and transportation considerations – trains, planes and automobiles.

Medical device design requirements

The primary EMI/EMC standard for medical electrical equipment and systems is IEC 60601-1-2. Developed by the International Electrotechnical Commission, this global standard applies to the basic safety and essential performance of medical equipment and systems in the presence of electromagnetic disturbances, and to electromagnetic disturbances emitted by equipment and systems. 

It also recognizes that RF wireless radio communications equipment (mobile phones, Wi-Fi and biotelemetry) can no longer be prohibited from the patient environment and medical equipment and systems.

However, the standard falls short of defining EMI/EMC test requirements for special environments and points to manufacturers addressing special environments in the risk assessment.

EMI Testing for Medical Devices - What you Need to Know, Parker Chomerics, Immunity vs. Emissions testing











Remember, the difference between emissions and immunity tests are that the emissions requirement is concerned with the amount of electromagnetic energy emitted from your device, while the immunity requirement is concerned with how susceptible your device is to electromagnetic energy existing in the location of end use. This includes energy being emitted from surrounding devices.

Current EMI/EMC standards for medical electrical equipment and systems in special environments
  • IEC 60601-1-2 – The basic document addresses emissions requirements for professional health care and home healthcare environments. Requirements are determined based on CISPR 11, IEC 61000-3-2 and IEC 61000-3-3 based on the environments of intended use.
  • IEC 60601-1-2 – The basic document addresses immunity requirements for professional health care and home healthcare environments
  • IEC 60601-1-2 – The basic document addresses immunity only in the automotive environment by including test requirements to ISO 7637-02 on direct current power inputs. This is being applied for both general automobile and ambulatory use.
  • IEC 60601-1-2 – The basic document addresses immunity testing for environments near RF wireless radio communications equipment.
  • Manufacturers should consider applying the emissions requirements of CISPR 25 and ISO 7637-2 for automotive environments. This is being used for both general automobile and ambulatory use.
  • Manufacturers should consider applying the emissions requirements of ISO 7137, RTCA DO-160 and EUROCAE ED-14 for aircraft environments. This is being used for both general aviation and medical helicopter use.
  • Manufacturers should consider applying the emissions and immunity requirements of IEC 62236-1 for railway environments.
  • Manufactures should consider applying ANSI C63.27 for coexistence of wireless systems equipment (cell phones, Wi-Fi and biotelemetry). This is being used to ensure that medical devices which incorporate an RF transmitter AND are used near each other operate correctly in any environment.
  • Product specific standards exist for specific types of medical electrical equipment and systems (endoscopic, infusion pumps, electrocardiograph, ultrasonic equipment etc.) that must be considered. In many cases these standards alter the basic requirements within IEC 60601-1-2.

Key takeaways

The world of medical devices is dramatically changing how medical electrical equipment and systems are being used in various environments. Many different EMI/EMC standards need to be considered to address all environments of intended use.

Parker Chomerics Test Services, in association with Parker Chomerics Applications Engineering can assist in determining what standards should be applied to your medical electrical equipment and systems and help ensure compliance to the requirements. Our extensive experience in solving EMI/EMC test failures will result in manufacturable solutions which will reduce your time to market.
