Healthcare & Pharmaceutical Parts Cleaning

Cleaning Technologies Group (CTG) is the source for precision cleaning technologies that meet the challenges of healthcare equipment cleaning, including pharmaceutical components, surgical tools, and dental instruments. Our equipment is designed to provide thorough, but gentle cleaning to remove all contaminants from part contours and surfaces for precision cleaning that meets the most rigorous standards.

Aqueous and Ultrasonic Healthcare Component Cleaning Equipment

Blackstone-NEY Ultrasonics and Ransohoff cleaning systems include aqueous and ultrasonic cleaning equipment for immersible healthcare tools, instruments, and devices that need to pass rigorous standards for cleanliness. Cleaning, passivation, and decontamination are included as part of our systems.

Blackstone-NEY Ultrasonics’ Aquarius system provides an effective system for cleaning healthcare components and devices with complete ultrasonic cleaning in a single step. We also offer a range of size appropriate options that will optimize efficiency.

Passivation & Ultrasonics

During passivation cleaning, a thin layer of oxidation forms on the part surface which acts as a protective coating. This happens naturally in stainless steels and titanium alloys, but the surface purity can be optimized by treating the materials in a controlled citric or nitric acid process. This film is about 100,000 times thinner than a human hair and though the layer can be removed through abrasion, it is extremely durable. The chemical action of passivation will actually penetrate 0.00508mm deep into the surface of the material.

Blackstone-NEY Ultrasonics ultrasonic cleaning and passivation systems rely on industry compliant fabrication processes and materials to deliver repeatable and reliable cleaning results. Industry-leading design technologies include redundant control measures, process traceability through data collection/access software, sanitary plumbing and filtration loops, and controlled environments.

Ultrasonic cleaning combined with pickling, passivation, rinsing, neutralization, and drying and other processing steps in a unitized cleaning console helps assure process integrity. An automated, robotic transfer system can be integrated to ensure process consistency and significantly reduce the labor required for part cleaning.

Using our Blackstone-NEY Ultrasonic technology, we have provided passivation systems to the dental, healthcare, and pharmaceutical markets. Our knowledgeable team supports customers in the early stages of process evaluation to ensure that the correct process and equipment is specified from the start of your project.

CTG Healthcare Cleaning Systems Meet Quality Standards

Good Manufacturing Practice (GMP) is a system for providing products that are consistently produced and controlled according to quality standards. All CTG equipment is manufactured according to GMP, which minimizes risks and helps to satisfy applicable end user internal ISO requirements.

Blackstone-NEY Ultrasonics also offers complete documentation according to GAMP 5, allowing for turn-key operation up to product qualification. Guidelines include:

  • Design Package
  • Equipment Documentation
  • IQOQ Procedure Development and Execution

Another quality advantage CTG offers healthcare component and device manfuacturers is an in-house lab for evaluating material compatibility and cleanliness. This allows us to evaluate an application prior to identifying and developing the most appropriate and effective parts cleaning solution.

Blackstone-NEY Ultrasonics Medical Device Cleaning Proven Successes

The Blackstone-NEY Ultrasonics Lean Aquarius ultrasonic tank to tank system provides anti-microbial cleaning and filtration, continuous flow cascading rinse tanks, an automated transfer system, data tracking, sanitization, and more, as well as 100 percent dry devices.

The Ransohoff LeanJet RB - Rotary Basket Washer can be a solution for cleaning dental instruments and other healthcare items. The LeanJet RB-1 handles 4 baskets of parts per hour with no visible debris using a 10x microscope. The system offers the added advantage of efficient operation and a small footprint. Ransohoff can also provide the right chemistry required to meet critical cleaning specifications.
