PHARMA MACHINERY GUIDE
Aseptic Packaging for Liquid Injectables Precision, safety, and innovation in sterile fill-finish manufacturing Harsiddh Unimach Pvt. Ltd. | Est. 1988 | ISO 9001:2015 & CE Certified
Why It Matters
Liquid injectables bypass the body's natural defenses and enter the bloodstream directly. For a drug that goes straight into circulation, there is zero margin for microbial or particulate contamination.
0% MARGIN FOR ERROR
Aseptic packaging is the discipline that makes this possible — sterilizing the product and its container separately, then combining them inside a contamination-free environment.
Harsiddh Unimach Pvt. Ltd.
Many biologics, vaccines, and protein-based drugs are heat-sensitive — terminal (heat) sterilization would destroy them. Aseptic processing is the only way to keep them both sterile and effective.

Aseptic vs. Terminal Sterilization
A
•
Aseptic Processing
Product and container are sterilized separately, then combined in a Grade A environment.
T
•
Terminal Sterilization
Product is filled, sealed, then sterilized as a finished, closed unit — typically by autoclave.
Used for heat-sensitive biologics, vaccines, and proteins.
Works well for stable, non-heat-sensitive formulations.
Relies entirely on environment and process control for sterility.
High heat would destroy the molecular structure of biologics.

Fill & Stopper
Piston or peristaltic pumps dispense liquid; ampoules are flame-sealed, vials immediately stoppered.

Cap
Aluminum caps are crimped over the stopper for a tamper-evident mechanical seal.

Piston vs. Peristaltic Pumps Feature
Piston Pumps
Peristaltic Pumps
Accuracy
Extremely high for viscous liquids
High, especially for low-volume doses
Contamination Risk
Requires thorough CIP/SIP cleaning
Single-use tubing eliminates cross-contamination
Material Sensitivity
May exert shear stress on biologics
Gentle on delicate molecules
Maintenance
Higher — moving parts contact the product
Lower — only tubing is replaced
Harsiddh Unimach offers customized filling solutions, letting manufacturers choose the pump technology best suited to their specific molecule.

The Sterile Environment Grade A / Class 100 — because the machinery is only as good as the environment it sits in.
H HEPA Filtration
High-efficiency particulate air filters provide constant laminar airflow that sweeps particles away from open containers.

Regulatory Snapshot
1
EU GMP Annex 1
Raises the bar on “Contamination Control Strategy” (CCS) — continuous environmental monitoring and a push toward automated, hands-free processing.
2
FDA 21 CFR 210 / 211
Centers on Media Fills (Aseptic Process Simulations) — running nutrient broth through the line to prove it stays sterile start to finish.
3
21 CFR Part 11
Modern machines must log every action — speed changes, alarms — electronically, with a tamper-proof audit trail.
