The breathability of ePTFE gives GORE® LYOGUARD® Freeze-Drying Trays its superior vapor transmission rate.

In the pharmaceutical industry, manufacturers must ensure the purity of their materials and the efficiency of their processes. Starting with the introduction of the GORE® LYOGUARD® Freeze-Drying Tray, a single-use lyophilization product, Gore has developed many single- and multi-use products and process components for transferring, storing, filtering and drug processing.  

We collaborate with manufacturers to design the solutions that fit their requirements for purity and help maximize process effectiveness. As with many Gore products, our life sciences solutions can provide high value by:

  • protecting and containing complex biologics
  • supporting speedy processing times
  • enabling secure fluid transfer and sampling
  • minimizing process disruption errors or issues

What differentiates Gore’s life sciences solutions is our deep understanding of fluoropolymers, particularly polytetrafluoroethylene (PTFE) and its expanded form. By utilizing our materials expertise we can design products with properties like low extractables and resistance to chemicals and extreme temperatures – for solutions that perform efficiently and more reliably than alternatives.

GORE ImproJect Plungers

Silicone-free GORE ImproJect Plungers minimize the risk of silicone-induced interaction

Our newest product, the GORE™ ImproJect™ Plunger, means that silicone-sensitive biologics can be packaged in pre-filled syringes without risk of silicone-induced interactions…and without jeopardizing consistent delivery performance over time. For the silicone-free GORE™ ImproJect™ Plunger, silicone oil is neither a raw material, nor used in the manufacture of these plungers. Additionally, the plungers are designed to work with bare glass (non-siliconized) barrels and testing demonstrates no significant extractable compounds, due to our plunger’s proprietary PTFE-based fluoropolymer barrier.

The GORE™ Protein Capture Device for small-scale affinity chromatography uses the unique properties of a proprietary ePTFE composite combined with Protein A to fundamentally improve the purification process. Designed for drug discovery and screening applications, it provides significant capacity and speed improvements in the purification of monoclonal antibodies.

The GORE® STA-PURE™ Flexible Freeze Container helps minimize the risk of losing valuable bulk drug substances during cold chain handling. Unlike other disposable storage containers which may become brittle after freezing down to -86°C, the single-use GORE STA-PURE Flexible Freeze Container uses a unique combination of PTFE composite film with low extractables and an innovative bag design to remain robust and resist breaks, cracks or leaks.

Good Manufacturing Practices

All Gore products for life sciences are manufactured specifically for use in medical device manufacturing or pharmaceutical settings and comply with regulations our customers may require. Depending upon those requirements, you will find products manufactured under Good Manufacturing Practices (GMP), ISO 13485 and ISO 15378 certifications; and/or regulations for food contact.

Drug Delivery and Packaging

Biologics manufacturers need pre-filled syringe (PFS) packaging solutions that both protect valuable drug product and offer optimal delivery performance. However, conventional PFS systems use lubricants like silicone that might put more complex and sensitive biologic drug products at risk. The new GORE™ ImproJect™ Plunger eliminates the need for silicone in both plunger and glass barrel, avoiding silicone-induced particle formation and protein aggregation while still providing needed device functionality.

Drug Delivery and Packaging

Single-Use Frozen Storage

In downstream bioprocessing, a common concern is the risk of losing product frozen in single-use containers during transport, storage or handling. Single-use GORE® STA-PURE™ Flexible Freeze Containers offer a new solution for bulk drug substance that protects container integrity with greater crack- and impact-resistance during cold chain handling. The proprietary, high-purity fluoropolymer container material has low extractables for added peace of mind.


Traditional protein purification processes may be time consuming and slow down small-scale drug discovery or antibody production operations. The GORE™ Protein Capture Device with Protein A eliminates those constraints. It combines high dynamic binding capacity with short residence times for the possibility of more highly-concentrated elution pools in less time.


Developed in consultation with the pharmaceutical lyophilization industry, GORE® LYOGUARD® Freeze-Drying Trays provide a cost-effective method of freeze-drying by containing product throughout the lyophilization process.

Peristaltic Pump Tubing

A failure during processing due to tubing rupture is just not an option. A significant loss of flow can be disruptive — manufacturers need consistent, repeatable and reliable results, every time. That’s why GORE® STA-PURE® Pump Tubing products are engineered to meet varied process challenges: to reliably protect against ruptures even at high pressures… to resist aggressive chemicals… to deliver consistent flow rates in peristaltic pumps for days, weeks, or even months.

Fluid Transfer and Sampling

The secure transfer and containment of liquids is paramount in pharmaceutical and biopharmaceutical processing. Gore offers a family of fluid transfer and sampling products to meet a variety of different pharmaceutical and bioprocess applications.

GORE™ Molded Assemblies are configured to individual customer requirements and may include platinum-cured silicone and thermoplastic elastomer (TPE) tubing, molded connections, unions and manifolds, clamps, and bottle top assemblies.
