Instrument-Integrated Pouches for Clinical Diagnostics

How Heritage supports today’s automated diagnostic systems

In the clinical diagnostics field, accuracy starts long before a sample reaches an analyzer. It begins with the diagnostic reagents, controls, and purge solutions that power every test. These materials need to move through automated systems cleanly and consistently, without contamination or variability. That’s where Heritage Packaging’s instrument-integrated pouches come in.

These aren’t open-top liners or carton bags. They’re fully sealed reagent pouches with molded fitments designed to connect directly to IVD instrumentation. Engineered for reliability inside automated analyzers, each pouch serves as a flexible reservoir that keeps essential diagnostic fluids flowing exactly as intended.

Precision-placed molded fitments for IVD instruments

Customers often come to us because we can install molded fitments in challenging locations - not just top center. Many converters can only support standard placement, but diagnostic instruments rarely follow standard geometry.

If your connection point is offset, recessed, angled, or uniquely positioned, we can place the fitment exactly where your IVD analyzer requires it. This capability is especially important for reagent cartridges, purge reservoirs, and other consumables that must slide into tight instrument bays or proprietary housings.

Designed for your platform and your workflow

Every diagnostic platform is different, so every pouch we build begins with understanding your system. We fabricate to your exact pouch configuration, including complex geometries and custom fitment placement. Or, if you’re developing a new instrument, we can engineer a glove-fit design that integrates directly with your container, cartridge frame, or diagnostic system.

This flexibility makes our pouches ideal for a wide range of IVD consumables, including:

• Diagnostic reagents

• Calibrators and controls

• Precision-dosed chemistry

• Wash and purge solutions

• Bulk reagents

• Direct-feed reagent reservoirs

• Instrument consumables

• Flexible reagent packs

Whether your consumable needs to lay flat, stand upright, lock into a cartridge, or plug into a fluidic pathway, we design the right configuration for your workflow.

High-barrier protection for sensitive diagnostics

Diagnostic solutions are sensitive to moisture, oxygen, UV light, and environmental exposure. Our pouches use high-barrier laminations to support reagent stability and extend shelf life. Every pouch is fully sealed with hermetic seals that protect chemical integrity and support consistent, contamination-controlled performance.

This is especially valuable for clinical chemistry, immunoassay reagents, and molecular diagnostics, where accuracy is everything.

Supporting the entire IVD workflow

From early-stage prototype development to full-scale production, we support every step of the IVD consumable lifecycle. Our instrument-integrated pouches help keep analyzers running at high throughput, reduce operator handling, and streamline consumable loading for lab automation.

35+ years of flexible packaging expertise

For more than three decades, Heritage Packaging has partnered with companies developing the next generation of life sciences and diagnostic technologies. We bring deep experience in custom flexible packaging, molded fitment installation, and precision fabrication, backed by the responsiveness of a family-owned business.

If your diagnostic instrument needs a better reservoir, we can engineer one that performs as reliably as the technology it supports.
