Both directly and through these partnerships, IMI delivers high-quality, high-value products that pharmacy operations demand, such as IMI’s Prep-Lock™ Tamper Evident Caps, that safeguard drug integrity and standardize drug security across medications from the moment they leave the pharmacy to the point of administration.

Product Overview
Prep-Lock™ Tamper Evident Caps for IV Syringes
Over 88% of the top 503B compounding facilities trust IMI Tamper-Evident Caps to secure their preparations. Hospitals that partner with an outsource compounder may already be familiar with Prep-Lock Tamper Evident Caps for IV Syringes. Incorporating these caps for in-house preparations can provide standardization of all syringes throughout the hospital. As a result, clinicians will not need training for administering syringes with multiple tamper-evident methods.
Now available in individual sterile blister packaging!
Prep-Lock™ Tamper Evident Caps With Male Luer Lock
The only cap of its kind provides a secure, all-in-one tamper-evident closure for CADD medication cassettes. By integrating closure and tamper-evident protection into a single solution, it removes the need for separate components — streamlining fill-finish workflows, strengthening drug security, and reducing material costs.
Prep-Lock™ Tamper Evident Additive Port Caps
Provide remarkable protection and protocol assurance to the medication ports of IV bags, including Baxter, B. Braun, Fresenius Kabi, ICU Medical, and more. The simple, one-handed installation is pharmacists’ preferred method to providing tamper-evident protection to IV bag preparations. Unlike other add port caps, IMI’s enclosed hinge and hidden lock design ensures that once the cap is applied to the medication port, it cannot be removed without damaging the bag.
Prep-Lock™ Tamper Evident Cap for Oral Syringes
The only tamper-evident cap available for oral syringes, IMI Caps are designed to each oral syringe manufacturer’s unique specification and feature a retained indicator ring for enhanced control of disposable components during medication administration.
Prep-Lock™ Tamper Evident Caps Compatible With ENFit® Syringes
Tamper Evident Caps for ENFit® Syringes are designed to provide secure tamper-evident closure to the ENFit connector standard (ISO 80369-3) and are the only ENFit Syringe Caps available with built in tamper-evident technology.
