Selecting the right size reduction equipment for the pharmaceutical industry is far more than a technical decision—it’s a strategic investment in your operation’s efficiency, safety, and regulatory success. At The Mark‑Costello Co., we provide a wide range of reduction systems including shredders, grinders, granulators, and micronizing mills, each engineered to address the unique demands of pharmaceutical manufacturing environments. What makes our solutions stand apart is not just the quality of the build, but the understanding that pharmaceutical operations require unparalleled consistency, documentation, and scalability.
Our shredders and granulators are designed for the initial reduction of bulk pharmaceutical materials such as dry active ingredients, excipients, and raw crystal forms. These machines are capable of handling input materials in various formats and reducing them to particle sizes that are ideal for further processing or mixing. The granulators use carefully calibrated rotor blades and screen combinations to maintain tight particle size distributions while avoiding over-shearing or thermal degradation. When needed, integrated cooling systems and dust containment modules are available to support heat-sensitive compounds and prevent airborne contamination, particularly important when dealing with potent ingredients.
For applications that demand ultra-fine particle reduction—such as dry powder inhalers, parenteral drugs, or high-potency oncology medications—our fine impact mills and air jet mills offer the precision needed to deliver particles in the micron or even sub-micron range. These machines employ highly controlled air streams or impaction forces to reduce materials while maintaining the product’s chemical integrity. We design these systems with containment in mind, offering glove box compatibility, nitrogen inerting, and pressure-rated housings to maintain safety and control exposure. Moreover, all of our equipment is available with GMP-certified finishes and Clean-in-Place (CIP) capabilities, helping your facility remain compliant with even the most rigorous inspection standards.
But selecting the right machine isn’t just about meeting today’s goals—it’s about preparing for what’s next. The Mark‑Costello Co. offers scalable designs that support laboratory-scale R&D, pilot-scale formulation development, and full-scale commercial production. Modular setups make it easy to switch between processes, formulations, or batch sizes without disrupting facility operations. Each piece of equipment can be integrated with automated control systems, including SCADA interfaces and data logging tools, to support audit trails, process validation, and 21 CFR Part 11 compliance. With us, you’re not just purchasing equipment—you’re securing a long-term processing solution that evolves alongside your product development roadmap.

Dear Mr. Markle,
I have been working in the Plant Operations of Hospitals for the past 20 years. During that time I have had the responsibility of maintaining various autoclaves for the treatment of biohazardous medical waste.
When I came to Doctors Medical Center a year and a half ago I found myself in charge of maintaining a Mark-Costello Co. autoclave that was nearly eight years old. After my past experience of trying to keep a high vacuum system with consistent problems in operation, I find maintaining the Mark-Costello gravity fed autoclave a pleasure, as there is seldom a malfunction. I attribute this to the fact they have kept the design simple with no need for highly technical maintenance and high dollar repair parts.
As a point of information, the Model we operate is a AS 512 equipped with a unique “pull out drawer” making it easy for the Housekeeping Staff to load. This unit has a capacity of approximately 750 lbs. per cycle.
We expect to keep our Mark-Costello autoclave in operation for another 8 years or longer !
Dear Mr. Markle:
San Ramon regional Medical Center has owned and operated a Model AS46 Mark-Costello Medical Waste Sterilizer for the past eight years. We are pleased with performance of this equipment and have had a fine working relationship with the Mark-Costello Company. The system continues to function well and allows our facility to avoid the liability and high cost of packaging and hauling untreated infectious waste.
We Anticipate several more years of operation from this waste treatment system
Saludos,
La presente es para agradecer sus servicios a nuestra compañia. Su equipo de trabajo ha sido muy atento y diligente en las gestiones realizadas. Estamos muy complacidos con el equipo, el precio y la calidad de sus servicios.
Esperamos seguir contando con una excelente relacion de negocios en un futuro muy cercano.
Greetings,
This letter is to thank you for your services to our company. Your teamwork has been very attentive and diligent in the way it has been carried out. We are very pleased with the teamwork, the price and the quality of your services.
We expect to continue an excellent business relationship with you in the near future.
To whom it may concern,
Pleased with the equipment
We are quite pleased with our Mark-Costello sterilizer. The sterilizer has been working fine for many years. We recently purchased additional equipment from them, and are impressed with their response time and friendly service. We hope to continue a great working relationship with Mark-Costello in the future for additional pieces of equipment.
“It’s been a great relationship with The Mark-Costello Company; they are very dependable to all of our waste handling requirements and have made us aware of the importance of recycling and the upcoming waste handling issues in the future.”
“We have been very pleased with the performance and the cost savings that the trash compactors from The Mark-Costello Company have provided to our school district.”
My name is David E. and I am responsible for a Mark Costello Co. Auto-Clave, at an inflight Kitchen out here in Kona Hawaii, that is overseen by the USDA / Custom and Borders, federal inspectors. (as you can imagine that is a challenge in its self).
The products that Mark Costello Co. is producing are of good quality. The auto – clave that I am responsible for works 24/7, with very few break downs. This is the only unit available in Kona, making daily operation is critical.
It is nice to know that when I call for tech support and parts, the courteous staff always responds promptly. Being out here in the middle of the pacific, that is crucial to our operation.
I would highly recommend Mark Costello Co.
You’ll want to include details about your product’s material characteristics such as particle hardness, moisture content, target particle size, throughput volume, and whether the product is heat- or pressure-sensitive. Let us know if your process requires containment, dust collection, or CIP systems so we can tailor the solution accordingly.
All of our equipment for the pharmaceutical industry is constructed with GMP-ready materials like 316L stainless steel, sanitary welds, and hygienic seals. We also supply IQ, OQ, and PQ documentation, as well as FAT and SAT services to assist with your validation process.
Yes, we design systems specifically for high-potency active ingredients (HPAPIs) with containment features such as glove box compatibility, HEPA filtration, and nitrogen inerting. We prioritize safety for both product and operator throughout the process.
We offer modular, scalable equipment that begins at the lab bench and can grow with you into commercial production. This helps maintain continuity in particle size distribution and process parameters, reducing the need for revalidation later.
Yes, many of our size reduction systems can be outfitted with CIP features, which are crucial for maintaining sterile conditions and reducing downtime between batches. CIP support is especially important in multiproduct facilities or when handling allergenic substances.
Typical lead times range from 10 to 16 weeks depending on complexity and customization needs. For lab-scale or standard units, turnaround may be faster. We recommend initiating your quote early to stay aligned with project timelines and regulatory deadlines.
