Capsule Checkweigher
This product has been discontinued
100% capsule weighing solution with world's highest-level precision and reliability.

Advanced quality control with the industry-leading weighing accuracy

Best weighing solution for capsules containing active pharmaceutical ingredients

Anritsu's force balance technology provides the maximum weighing accuracy of ±0.5 mg, meeting even the most stringent standards for cuspules such as anticancer drugs and immunosuppressive drugs, in which only small changes in quantity could affect both intended effects and side effects.

Contribution in yield improvement

High-precision weighing enables you to set the upper and lower limits of the checkweigher closer to the permissible weight limits for your product quality control standard. As a result, the ratio of non-defective products will increase, contributing to improved production efficiency and reduction of raw material costs.

Anritsu's force balance load cell achieves maximum weighing accuracy of +/- 0.5 mg.

The most reliable capsule handling system

Capsules placed in the hopper are divided into multiple lanes by a magazine, and are transported, weighed, and sorted with a maximum throughput of 75,000 / hour*. The newly developed handling mechanism has significantly improved reliability and environmental flexibility in capsule handling. It can handle a variety of capsules, including filled and empty capsules. The feeding mechanism is easy on capsules as it reduces static electricity, and also ensures precise inspections and reliably rejects improper weight products.

*: A model with the maximum throughput of 150,000 capsules / hour from the previous version is also available.

New capsule handling mechanism of the capsule checkweigher

Enhanced fail-safe mechanisms

In case of unexpected malfunction and troubles
If the power is cut off due to a power outage or lightning strike and the measurement becomes impossible, both the rejection and the exclusion gate immediately operate to eliminate all the capsules being transported and do not transport them to the subsequent stage.

Enhanced fail-safe mechanisms with Exclusion gate and Rejection gate.

Enhanced safety with interlock system
The panels covering the magazine and conveyor are fully transparent and have no blind spots. Good visibility facilitates checking for residual capsules, helping to prevent cross contamination. The covers can be opened and closed without tools. If any cover is open, the equipment is stopped with the interlock for safe operation.

Quick, tool-free part exchange

The parts for each capsule size can be attached and detached without tools. The magazine and conveyor are easily accessible and can be held firmly with both hands. Compared to the previous model, the number of parts has been reduced, which decreases the changeover time to one minute or less.

Replacing the capsule magazine.

Conforming to international industry standards and regulations

The system supports user authentication, audit trails, and data encryption/decryption required by FDA 21 CFR Part 11 (optional).
The parts in contact with capsules are made of materials compliant with FDA 21 CFR Part177. (The material certificate and the processing certificate are available.)

Overview
Anritsu's high precision Capsule Checkweighers weigh 100% capsules reliably at high speed.

It is equipped with the newly developed capsule handling mechanisms which ensure highly reliable capsule feeding, weighing, and rejection. Anritsu's force balance weighing technology provides the industry's highest weighing accuracy of ± 0.5 mg, contributing to more advanced quality control and improved production efficiency.

Major benefits with Anritsu Capsule Checkweighers are shown below.

  • World's highest level precision weighing, the maximum accuracy +/- 0.5 mg in 3 sigma.
  • Yield improvement: High-precision weighing enables you to set the upper and lower limits of the checkweigher closer to the permissible weight limits for your product quality control standard.
  • The new handling mechanism ensures reliable capsule feeding, weighing, and rejection
  • Quick, tool-free part exchange
  • Large 15-inch touch panel with user-friendly GUI shows complete line status up to 10 lanes in a single screen.
  • Automatic sensitivity check function: It only takes 30 seconds for the built-in weight check to verify weigh cell sensitivity.
  • Enhanced fail-safe structure: When power outage is caused, both the rejection and the exclusion gate immediately eliminate all the capsules being transported.
  • Conforming to international industry standards and regulations (FDA 21 CFR Part 11, exc.)
