In environments where sterility is non-negotiable—such as pharmaceutical manufacturing suites or surgical operating rooms—the right choice of gloves plays a critical role in protecting both the user and the process. Yet not all sterile gloves are created equal. While sterile cleanroom gloves and sterile medical gloves may appear similar at first glance, they are engineered for distinct purposes, environments, and compliance standards.
This article is designed to guide professionals working in cleanroom-controlled industries and healthcare settings through the essential differences between these two types of gloves. In the following sections, we’ll explore the core features of these two types of gloves and highlight how they differ. Before we go into the two different types of gloves, let’s discover what sterile gloves are.
What are Sterile Gloves?
Sterile gloves are gloves that have undergone a validated sterilization process to eliminate all viable forms of microbial life, including bacteria, viruses, and fungi. This ensures they are safe to use in procedures or environments where sterility is critical to protect patients, products, or processes.
Common sterilization methods include:
- Gamma irradiation – the most widely used method for both cleanroom and medical gloves. It penetrates the packaging and effectively sterilizes the product without heat or moisture.
- Ethylene oxide (EtO) – used primarily for gloves that may be sensitive to radiation or require low-temperature sterilization.
- Steam sterilization (autoclaving) – less common for disposable gloves but used in specific reusable applications.
Sterile gloves are individually packed (in pairs), clearly labeled as "sterile," and come with traceability information such as lot numbers, manufacturing date and expiration dates indicating the integrity of the sterility assurance.
While both cleanroom and medical gloves can be sterile, their differences lie in how they are manufactured, tested, and used—depending on whether the focus is contamination control or patient protection. These differences are explored in the following sections.
What’s the difference between Clean & Sterile Cleanroom Gloves Vs Medical Sterile Gloves?
| Category | Clean Cleanroom Gloves | Sterile Cleanroom Gloves | Sterile Medical Gloves |
|---|---|---|---|
| Definition | Disposable gloves manufactured in cleanroom environments with low particulate, chemical, and microbial contamination. | Undergo the same manufacturing as clean gloves including validated sterilization processes, designed for aseptic cleanroom applications. | Medical-grade disposable gloves are sterilized for use in surgical, diagnostic, and patient care environments. |
| Primary Purpose | Designed for contamination control in cleanrooms where product integrity is critical, but sterility is not required. | Provide both contamination control and sterility, ideal for aseptic manufacturing and sterile cleanrooms. | Protect patients and healthcare professionals from biological contamination, especially during medical procedures. |
| Manufacturing Environment | Post processed and packed in ISO-classified cleanrooms (e.g., ISO Class 7 or 8) following stringent cleanliness protocols. | Post processed and packed in ISO 5 and higher cleanrooms and sterilised with validated sterility assurance levels (e.g., SAL 10⁻⁶). | Manufactured under regulated medical device environments per FDA, EN 455, or ASTM D3577 standards. |
| Post-Processing Methods | Gloves are rinsed with deionized water to ensure low residual contamination. | Undergo the same processing as clean gloves, followed by sterilization via gamma irradiation or ETO. | Typically sterilized but not subjected to cleanroom rinsing or particle/ion reduction processes. |
| Packaging Format | Packaged in non-linting, cleanroom plastic packaging, typically double-bagged with carton liners for clean transfer. | Double or triple-bagged carton liners for aseptic transfer and handling. | Packaged for sterile clinical use but not designed for cleanroom compatibility, clean handling, or low-shedding materials. |
| Sterility | Non-sterile; not suitable for aseptic tasks but ideal for particulate control. | Sterile, suitable for high-risk cleanroom environments requiring aseptic handling. | Sterile, suited for clinical, surgical, and diagnostic use where infection prevention is critical. |
| Shelf Life & Storage | Requires clean, dry storage away from UV and contaminants to maintain low particulate integrity. | Requires sterile storage with validated shelf life. | Requires dry, temperature-controlled storage to maintain sterility and material integrity. |

In summary, while sterile medical gloves are designed to protect patients and healthcare providers during clinical procedures, they are not suitable for cleanroom environments due to their lack of clean processing and particulate control. In contrast, clean and sterile cleanroom gloves are manufactured and packaged to meet the stringent cleanliness and contamination control standards required in life sciences and critical cleanroom applications.
Why Clean and Sterile Cleanroom Gloves Matters?
In regulated industries like pharmaceuticals and biotechnology, clean and sterile cleanroom gloves are not just part of personal protective equipment—they are a critical control point in maintaining product sterility and complying with EU GMP Annex 1 requirements.
Unlike sterile medical gloves, which are intended for patient care in clinical settings, cleanroom gloves are designed for use in aseptic manufacturing environments, such as Grade A and B cleanrooms, where particulate cleanliness, microbial control, and packaging integrity are essential to prevent contamination and achieve compliance with Annex 1 requirements.
Choosing the Right Clean and Sterile Gloves for Cleanroom Use
When selecting gloves for cleanroom applications, it’s vital to ensure they meet the highest standards for cleanliness and contamination control. Our clean and sterile glove portfolio are validated with a suite of certifications, technical testing and quality statements. The right gloves not only protect personnel but also safeguard products and processes from contamination.
