Eye Drop Filler Capper

It is ideal for sensitive ophthalmic, otic, and nasal liquid formulations. It works with both glass and plastic bottles/vials in volumes generally from 5 ml to 100 ml (with options for smaller sizes). The machine supports various bottle shapes and liquid viscosities and is used across pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries.

Empty bottles are fed via an unscrambler or conveyor and positively indexed by a rotary star wheel. At the filling station, high-precision pumps (peristaltic, piston, or ceramic) deliver accurate micro-doses. Bottles then move to the plugging station where vibratory bowls and pick-and-place systems insert dropper plugs. Finally, outer screw caps are applied with torque-controlled heads, and finished bottles are discharged to secondary packaging.

Filling accuracy is typically ±0.5% to ±1–2% depending on the pump system, minimizing product giveaway. Production speeds range from 40–100 bottles per minute on compact models up to 120 bph (or higher, 300+ on high-speed lines), depending on configuration and bottle size.

The machine uses peristaltic pumps (liquid contacts only sterile silicone tubing), piston pumps, or ceramic rotary piston pumps. These provide precise volumetric dosing without contaminating the product and are especially suitable for high-value, sensitive ophthalmic liquids.

It features stainless steel (316L) construction, operates under laminar flow, and can include isolators, ORABS, HEPA filtration, and nitrogen flushing. The closed-system design minimizes human intervention and microbial contamination risk. It is built to meet GMP, FDA, EMA, and WHO guidelines for ophthalmic and nasal products.

Key features include “No bottle, no fill” sensors, automatic stop on errors, defect detection and rejection systems, torque-controlled capping to prevent over- or under-tightening, and in-process controls. PLC-based digital interfaces allow easy monitoring and adjustments.

Yes. Many models are monoblock (integrated filling-plugging-capping) units and can form part of full lines that include bottle unscrambling, nitrogen purging, labeling, inspection, and cartoning for end-to-end automated production.

Benefits include high dosing accuracy and consistency, enhanced sterility, significantly higher throughput versus manual methods, reduced labor and material waste, regulatory compliance, and versatility across bottle sizes, shapes, and liquid types—leading to better yield and cost efficiency.

Typical specifications include ±0.5% filling accuracy, 5–100 ml bottle volume range, maximum speed around 120 bottles per hour (higher on other configurations), compatibility with glass and plastic bottles, PLC-based controls with digital interface, 3-phase 415 V 50 Hz power (adjustable), and options for HEPA filtration and nitrogen flushing. Contact parts and construction follow GMP standards.
