Used Capsule Checkweighers

Capsule checkweighers verify the fill weight of individual capsules and automatically reject units outside specified tolerances. These systems ensure dosage accuracy and regulatory compliance by identifying underfilled, overfilled, or empty capsules before packaging. Checkweighers can operate in-line with capsule fillers or as standalone quality control stations.

Federal Equipment Company stocks used capsule checkweighers from manufacturers such as IMA, Bosch/Syntegon, Anritsu, CI Electronics, Harro Hofliger, and Shionogi Qualicaps. Our inventory includes benchtop weight sorters and high-speed production checkweighers capable of processing up to 120,000 capsules per hour.

Capsule checkweighers use precision load cells or electromagnetic force restoration scales to measure individual capsule weights at production speeds. Capsules are fed from a hopper, singulated, weighed, and then sorted into accept or reject streams based on programmed weight limits. High-speed systems achieve throughput rates exceeding 100,000 capsules per hour while maintaining accuracy within ±2 mg.

Modern checkweighers offer multiple lane configurations to match production requirements. Single-lane benchtop units serve R&D and small-batch applications. Multi-lane systems with 10, 12, or 16 parallel weighing stations handle high-volume production lines. Dual-sided configurations allow operators to manage two product streams from a single control console.

Federal Equipment Company carries capsule checkweighers from IMA (Precisa 12, 18, and 120 series), Bosch/Syntegon (KKE 1500, 1700, and 2000), Anritsu (K525D, KW9001AP, KW9002AP), CI Electronics (SADE P2, P4, SP200, SP240), Harro Hofliger (KWS 12-S, Omnicontrol, Accura-C), Shionogi Qualicaps (CWI-40, CWI-80), and ACG-Pam. Change parts for multiple capsule sizes are often available with the equipment or can be sourced separately from PharmParts. Our technicians can inspect, calibrate, and test checkweighers at our facility prior to shipment.

Why Buy Used Capsule Checkweighers?

Used capsule checkweighers provide a cost-effective path to 100% weight verification without the capital investment of new equipment. Pre-owned systems from established manufacturers typically cost 40-60% less than new machines while delivering equivalent accuracy and throughput. This allows manufacturers to add quality control capability, establish redundancy for critical production lines, or equip multiple filling lines with dedicated checkweighers.

Lead time offers another advantage. New high-speed checkweighers often require months for delivery. Used equipment from Federal Equipment Company can ship within days or weeks after inspection, calibration, and testing. Change parts for multiple capsule sizes are frequently available from our inventory to support your specific production requirements.

Federal Equipment Company can inspect, calibrate, and test capsule checkweighers prior to shipment. Our technicians verify scale accuracy, check reject system function, and document equipment condition.
