Pharmaceutical companies are now choosing to select capsules as an alternative to simply providing packaging options; it is no longer simply selecting a type of capsule but is becoming a strategic choice due to changing consumer demands, tightening regulations and the increasing complexity of the pharmaceutical products being manufactured.
HPMC Capsules have quickly gained popularity over traditional gelatin capsules, largely based on their versatility, stability and compatibility with modern pharmaceutical and nutraceutical products.
While HPMC capsules meet the needs for plant-based products, they also provide other distinct benefits when compared to gelatin capsules, including better formulation performance, higher manufacturing efficiencies and improved product quality.
The choice between HPMC and gelatin capsules affects product performance, consumer acceptance, sourcing flexibility, and overall market positioning.

What is the purpose of a capsule elevator in pharmaceutical manufacturing?
An automated capsule elevator can be used to move capsules from one stage of production to the next. It enables better production efficiencies, better cleanliness/hygiene levels as well as it provides consistency of operations.
How does a capsule elevator improve GMP compliance?
Automated capsule elevators assist in reducing employee interaction with equipment, support a “dust-free” environment during transfer operations, and utilize hygienically constructed materials such as stainless steel, which is acceptable for GMP compliant production areas.
Can capsule elevators be integrated with existing production lines?
Most modern capsule elevators have been designed to easily interface with various levels of production including but limited to; capsule filling machines, packaging machinery, and material handling systems.
Are capsule elevators suitable for nutraceutical manufacturing?
Yes. Automated capsule elevators have become a staple in the design of many nutraceutical and healthcare supplement production facilities due to their ability to transfer capsules in a clean/hygiene-controlled manner.
What are the maintenance requirements for capsule elevators?
You should clean all surfaces; inspect components; lubricate moving parts; and perform routine preventive maintenance to make sure your capsule elevator is reliable for the duration of its service life.
