When it comes to sterile compounding, IV bags play a foundational role in ensuring safety, compliance, and clinical performance. But not all IV bags are created equal—and not all port configurations suit every application. Whether you're preparing high-volume injectables, aseptically filtering hormones, or supplementing post-fill additives, the right combination of ports can significantly impact both workflow efficiency and regulatory readiness.
At International Filter Products, we offer FDA-cleared, Rx-certified EVA IV bags engineered specifically for use in compounding pharmacies, hospital pharmacies, biologics, and specialty injectables. Our sterile EVA pillow bags are designed with three critical ports—female luer lock, spike, and injection—to support a wide range of applications with maximum sterility and flexibility.
Why Port Choice Matters
The configuration of an IV bag is not a secondary detail—it’s a primary determinant of its safety, compatibility, and use case versatility. Port design influences how a bag is filled, how medication is administered, and how well it integrates with the broader compounding or clinical workflow.
For example, choosing an IV bag with only a spike port may limit your ability to perform closed-system filtration. A bag without an injection port may prevent post-fill supplementation. And a lack of luer connectivity might require additional adapters, introducing unnecessary risk and inefficiency.
That’s why all Rx-certified EVA IV bags from International Filter Products are designed with three distinct port types, each supporting specific sterile functions, allowing compounding facilities to operate with confidence and flexibility.
Port Types
The three primary IV bag port types found on modern EVA bags are as follows:
Female Luer Lock Port
The female luer port is threaded to create a secure, leak-proof connection with male luer devices. This port is essential for closed-system drug transfer, sterile filtration, and integration with compounding pumps or filling machines. For pharmacies prioritizing repeatable, closed-loop filling processes, luer ports are indispensable.
The luer lock configuration also minimizes the need for external adapters, helping reduce contamination risk and simplifying quality assurance protocols. All International Filter Products’ sterile IV bags come with a female luer port that meets ISO 80369‑7 connection standards for safe and secure pharmaceutical applications.
Spike Port
Spike ports are puncturable, self-sealing access points designed to accommodate standard IV infusion spikes. This port is primarily used for gravity-fed administration in clinical environments, such as infusion centers and hospitals.
More importantly, when sterile transfer is required, spike ports must maintain compatibility with FDA-cleared transfer spike assemblies. For instance, IFP’s Transfer Spike Assembly (IFP‑081‑2326) is an ideal fit for our EVA IV bags, providing a validated closed-system fluid transfer pathway that ensures sterility from start to finish. This makes the spike port an essential option not only for administration but also for sterile solution transfers between bags, reservoirs, and devices.
Injection Port
An injection port consists of a needle-accessible membrane—usually latex-free and self-sealing—for post-fill medication additions. This port enables pharmacists to supplement bags with additives, preservatives, or vitamins after the initial compounding stage.
Injection ports are especially valuable in hormone therapy, pediatric nutrition, and biologics, where formulations may require last-minute adjustments. Each Rx-certified IV bag from IFP includes a secure injection port tested for puncture resistance and re-sealing integrity, meeting the highest standards for repeated access in sterile conditions.
Post-Fill Security
Port design also affects what happens after the fill process. In sterile compounding, the risks of contamination do not end once the bag is filled. In fact, maintaining the integrity of the bag through storage, transportation, and final administration is just as critical.
Our IV bags are designed with post-fill security features including:
- Tamper-evident luer caps to seal off luer ports
- Self-sealing injection ports for multiple needle entries without compromising sterility
- Inviolable clamps to isolate the bag’s content once filled
- Medical-grade packaging (blister + Tyvek) to maintain sterility through transport
Each component is validated to meet FDA and USP standards, making our sterile IV bag portfolio an ideal choice for sterile applications that demand complete traceability and protection.
Fewer Adapters, Fewer Risks
In sterile compounding, every added connector or adapter increases operational complexity, potential leak points, and the risk of contamination. A properly configured IV bag eliminates unnecessary accessories, streamlining the sterile workflow and reducing regulatory burden.
For example, bags equipped with female luer ports can connect directly to compounding pumps or sterile filters without requiring extra connectors. This simplifies the filling process, reduces human error, and accelerates throughput—all while ensuring compliance with compounding SOPs.
At International Filter Products, our Rx-certified EVA IV bags are designed to integrate seamlessly into your workflow with minimal hardware dependencies.
Materials and Compliance
Material compatibility is just as important as port configuration. IV bags used in compounding must be manufactured from materials that are:
- Chemically compatible with both aqueous and oil-based medications
- Free from leachables that may interact with sensitive APIs
- Sterilizable without degradation
- Biocompatible under ISO 10993 standards
Our EVA IV bags are:
- Latex-free, DEHP-free, and non-toxic
- Sterilized via ETO to a Sterility Assurance Level (SAL) of 10⁻⁶ in accordance with ISO 11135
- Validated for endotoxins (USP <85>) and pyrogens (USP <151>)
- Tested per ISO 10993-5, -10, and -11 for cytotoxicity, sensitization, and systemic toxicity
This level of validation ensures that our IV bags meet the stringent quality expectations of regulated healthcare and compounding environments. An upcoming blog will cover the full range of materials used in IV bag manufacturing and their specific applications.
Port Use-Cases in Sterile Compounding
Each port has a specific role in clinical or pharmaceutical settings:
- Luer ports are used in 503A/503B pharmacies for sterile filling, filtration, and integration with automation equipment.
- Spike ports are used in infusion clinics and hospitals to connect to IV tubing or transfer assemblies.
- Injection ports are used in cleanrooms to add drugs post-fill, especially in hormonal therapy or customized biologics.
Whether preparing semaglutide injections, testosterone in oil, or combination therapies, these port configurations give pharmacists the flexibility to perform each step with sterility and confidence.
Selecting the Right Configuration
Selecting the appropriate IV bag port configuration depends on your specific workflow. Consider the following:
- Will the bag be connected to a sterile filter or repeater pump? A luer port is essential.
- Will the bag be administered via gravity drip? A spike port is required.
- Will any drugs be added post-fill? An injection port must be present.
- Is the bag being used for aqueous, oil-based, or biologic medications? Choose a bag with EVA material and FDA Rx clearance.
Every sterile EVA IV bag we offer is validated and Rx-certified, making them suitable for high-risk medications, specialty therapies, and clinical infusions. Our product range covers volumes from 150 mL to 5 liters, with reinforced structure included for larger capacities.

Why FDA-Cleared and Rx-Certified Matters
The term “Rx-certified” is not a marketing phrase—it is a regulatory requirement for any container used in the preparation and storage of sterile, prescription medications. Many generic IV bags on the market are not FDA-cleared, which presents real risks, including:
- Failing quality inspections or audits
- Incompatibility with injectable drug formulations
- Increased risk of leachables, contamination, or sterility breaches
- Non-compliance with USP <797>, <800>, and state board requirements
By choosing our FDA-cleared, Rx-certified IV bags, compounding pharmacies and hospitals ensure compliance with 21 CFR Part 880.5025, ISO standards for medical devices, and all relevant USP chapters.
