The Erweka tester tests a tablet placed on the lower anvil and a weight moving along a rail transmits pressure slowly to the tablet. [5] The Dr.Schleuniger Pharmatron tester operates in a horizontal position. An electric motor drives an anvil to compress a tablet at a constant rate. The tablet is pushed against a stationary anvil until it ...
The history of the Schleuniger Group as it is known today started in 1991 when Dr. Gerhard Jansen (Chairman BOD until 2009) and Martin Strehl (CEO until 2009) acquired Sutter Electronic AG located in Thun, Switzerland. At that time Sutter Electronic AG had 30 employees and generated a revenue of 5 million CHF with wire processing machines and ...
The CD V-700 Model 7 is a kit to upgrade and modernize the Lionel Model 6B, Lionel/Anton Model 6, or Electro-Neutronics 6B with electronics derived from a recent version of the Ludlum Model 3 Geiger counter. The kit includes a new main electronics board with rotary switch, a connector for a detachable external probe, a wiring harness and ...
A tablet press in operation An old rotary tablet press. A tablet press is a mechanical device that compresses powder into tablets of uniform size and weight. A tablet press can be used to manufacture tablets of a wide variety of materials, including pharmaceuticals, nutraceuticals, cleaning products, industrial pellets and cosmetics.
The user guide engraved into a model of the Antikythera Mechanism. User guides have been found with ancient devices. One example is the Antikythera Mechanism, [1] a 2,000 year old Greek analogue computer that was found off the coast of the Greek island Antikythera in the year 1900. On the cover of this device are passages of text which describe ...
In the pharmaceutical industry, drug dissolution testing is routinely used to provide critical in vitro drug release information for both quality control purposes, i.e., to assess batch-to-batch consistency of solid oral dosage forms such as tablets, and drug development, i.e., to predict in vivo drug release profiles.

A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
The simplest tester is the filament continuity tester, usually with a neon lamp connected in series with the filament/heater and a current limiting resistance fed directly by the mains. There is therefore no need to select the appropriate filament voltage for the particular tube under test, but this equipment will not identify tubes that may be ...
