The drug industry has greatly evolved through the years, but tablets still make up the majority of its products. From the
beginning, companies have conveyed and compacted powdered ingredients to create this dosage form. Over time, tablet configurations
have evolved to accommodate multiple layers and potent ingredients. This month's products show how manufacturing equipment
has developed along with the dosage form. A granulator from GEA Pharma Systems has been adapted to provide containment. Glove
boxes from Labconco can be cleaned thoroughly and quickly. David Round's lift tables can be adjusted to appropriate ergonomic
High-shear granulator provides containment
The UltimaPro-HC high-shear granulator from GEA Pharma Systems is configured for high-containment applications. The unit performs
dry blending, wetting, and granulation, and its drying technologies enable the production of granules ready for tableting.
Clients can choose models fitted with vacuum drying, gas-assisted vacuum drying, and microwave drying technology. The vacuum-drying
unit is designed to optimize organic-solvent recovery. This unit combines vacuum pumps and condensors to recover solvent through

The UltimaPro machine also accommodates process analytical technology by performing torque measurement to help operators determine
the endpoint of the granulation process. The unit can be equipped with other real-time-release monitoring tools, such as the
GEA LightHouse probe. This probe is a process interface for fiber-optic techniques (e.g., near-infrared spectroscopy) that
allows users to clean the in-process window at any time.
Lift tables incorporate protected hydraulic packages
The David Round Company's 304 stainless-steel lift tables are designed for bulk-material applications in controlled pharmaceutical
manufacturing environments (e.g., cleanrooms). The machines' hydraulic packages are laid out flat on the bottom of the tables,
and the cylinders are in a horizontal position. This design enables the hydraulic components to be covered, thus protecting
them and reducing opportunities for contamination. Personnel can operate the tables' hydraulic packages with pushbutton controls.
The tables can be raised as high as 42 in.

Glove boxes provide operator protection
Labconco's Protector high-efficiency particulate air and ultralow particulate air filtered glove boxes provide a high level
of containment or isolation. The company tests its glove boxes with helium to ensure the absence of leaks greater than 1 ×

In addition, operators can clean Protector glove boxes quickly, thus reducing the time it takes to change between potent materials.
After 5 min of glove box air-volume dilution at 85 fpm, a perimeter scan detected an average tracer-gas level of 0.05 ppm,
according to Bob Applequist, a product manager at Labconco. The glove boxes' design thus helps ensure user protection.
The units' liquid crystal microprocessor display enables the real-time monitoring of air-volume dilution rates in cubic feet/min
and air changes/min. The display also measures the main chamber's static pressure in inches of water. An audible and visible
alarm trips when airflow or pressure is below selectable air-pressure limits.
