Pharmaceutical Grade Adsorbents Across the Manufacturing Chain

The pharmaceutical sector runs the most demanding quality regime of any SorbiTech industry. Every adsorbent shipment is documented to USP and EP grade specifications; every batch carries a certificate of analysis with full traceability from raw material lot through to packaged drum; every change in process or specification requires written notification under change control. SorbiTech serves the sector with SorbiTech pharmaceutical grade activated carbon, pharma grade carbon molecular sieve for on site nitrogen, silica gel sachets for packaging, and lab grade adsorbents for analytical separation.

API Purification and Decolorization

Active pharmaceutical ingredient (API) production generates colour bodies, residual catalysts, and trace impurities that must be removed before the final crystallisation. SorbiTech pharmaceutical grade PAC is dosed into the contact reactor, given controlled residence time at the working temperature, then filtered with a 0.2 micron sterile filter or a guard filter ahead of the next process step. Grade selection follows a laboratory decolorization test against the specific API; the recommendation is documented in writing and forms part of the change control package.

GMP Compliant Nitrogen for Reactor Blanketing and Sterile Filling

Sterile pharmaceutical manufacturing requires inert atmospheres for reactor blanketing during synthesis and for the sterile filling line in finished product packaging. A SorbiTech PSA nitrogen generation package charged with CMS N₂ grade delivers 99.9 to 99.999 percent purity at the contracted flow, with continuous purity monitoring and automatic off specification venting. The package is built to ASME and PED with GAMP 5 compliant controls for the sites that operate under FDA validation.

Packaging Desiccation for Moisture Sensitive APIs

Moisture sensitive APIs and finished products (tablets, capsules, lyophilised vials) require controlled humidity in the primary and secondary packaging. SorbiTech supplies silica gel sachets and molecular sieve 3A canisters matched to the product moisture sensitivity, the packaging volume, and the contracted shelf life. The canisters are filled under controlled humidity and ship with a certificate of analysis covering moisture content, microbial limits, and visual specification.

Activated Carbon for Solvent Recovery

Pharmaceutical solvent recovery from process vents (acetone, ethanol, methanol, ethyl acetate, dichloromethane) uses SorbiTech pellet activated carbon in a VRU that captures the solvent, regenerates the carbon with steam or hot inert gas, and condenses the recovered solvent for reuse. Recovery rates of 95 percent or higher cut the solvent purchase cost and the regulated emission to the stack.

Documentation, Audit, and Change Control

Every SorbiTech shipment to a pharmaceutical operator carries the documentation that the GMP regime requires: certificate of analysis, material safety data sheet, traceability from raw material lot, and change control notifications for any specification or process modification. The SorbiTech manufacturing facility supports FDA and EMA audits with the operator at the manufacturing site on request. The pharmaceutical industry team retains the documentation under controlled retention per ICH guidelines.
