Five-in-one testing with the Erweka Multicheck 5.1

August 2012 Analytical Instrumentation & Environmental Monitoring

MultiCheck 5.1 offers fully automated measurement of weight, thickness, diameter, hardness and width of up to 1200 samples, such as round or odd shaped tablets and hard or soft gelatine capsules. The advanced design of the unit offers innovative functions such as switchable hardness testing principle (constant-speed and constant-force), fully automatic speed adjustment of tablet processing, advanced high-accuracy thickness measuring system and state-of-the-art alignment tool for irregular shaped oblongs and coated tablets.

The system is equipped for separation of samples via an oscillating funnel. In standard configuration the MultiCheck 5.1 offers an integrated Sartorius weighing cell (accuracy ±0,1 mg). Furthermore, it can be fitted with an alignment flap which allows aligning and holding oblongs in the correct position for breaking. In combination with the Erweka TabSelect flap and the Venturi air transport system, it can be connected to any single or double sided tablet press.

Advanced sample segregation system

The advanced sample segregation system offers easy adjustment independent of sample kind and shape: fast individualisation, secure operation, easy cleaning and quick emptying. The samples are separated automatically via the oscillating funnel and then deposited onto the weight measurement boat. From there the samples are transported to the test stations by a linear feeder which allows alignment of oblongs as well as odd shaped samples.

MC.net software included

Erweka MC.net software is connected via Ethernet to the Multi-Check 5.1. The software allows PC operated external control of the hardness/combination tester as well as online storage of user management, product data and results. It also provides a CFR 21/11 compliant audit trail.

Tolerances for test-results can be individually or automatically set according to USP or Pharm.Eur. An optional alarm function stops the unit from continuing the test should a sample measure out of the set pass/fail tolerance. In this case the user may check why the measured result is out of the pass/fail limit.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
