The filler, before it reaches the mixer. Carbon black characterisation — oil absorption, pellet hardness and strength, sieve residue and compressed volume.
Motorised 14-position sample carousel option for the IPHT. It gives random access to any sample position under control of the IPHT software and pneumatically cleans the sample container between tests; it can be removed at any time to use the IPHT as a simple tester.
Void-volume tester for carbon black, derived from ASTM D6086 and compliant with ASTM D7854. Two force sensors measure applied and transmitted pressure through controlled compression and decompression, and the software also derives residual void volume, material friction and electrical conductivity.
Oil absorption system that characterises the structure of carbon black and silica to ASTM D2414 (OAN), ASTM D3493 (COAN), ASTM D6854, ISO 4656 and ISO 19246. It records mixing torque against oil volume, applies normalisation against reference materials, and is operated from a panel-mounted 7" screen or a connected PC.
Automated tester for the individual crush strength of carbon black pellets, compliant with ASTM D5230 and ISO 8942. It measures force up to 250 cN and pellet size from 0.8 to 3.5 mm, with an integrated random access sample buffer and damping table, controlled from a Windows PC.
Test equipment that determines the mass strength of pelletized carbon black to ASTM D1937 by measuring the force needed to pack a cylindrical column of pellets. It is a standalone table model with a programmable controller, a 500 N load cell and a stepper-driven plunger with position feedback.
Hydraulic press for preparing compressed carbon black samples to ASTM D3493 and ISO 4656 ahead of a COAN determination. It applies a fixed 165 MPa to the sample inside an enclosed chamber with a transparent door and a rear connection for the laboratory exhaust system.
Floor-standing test set that determines non-dispersible matter in carbon black and other powders by mechanical water flushing, following the functional principle of ASTM D7724. It runs a fully automatic program with a 50 litre collecting tank, an integrated water pump and 105 mm sieves.
Bench-top sieve residue tester for carbon black and other powders, working by mechanical water flushing to ASTM D1514, ISO 1437 and JIS K 6218-3. Measurement ranges run from 0.020 mm to 0.8 mm using 50 mm sieves in a sealed, dust-free stainless steel vessel.
Sieve residue testing device (Mocker apparatus) for pigments, extenders and other powders, designed to DIN EN ISO 787-18. A water jet rotor circulates the sample inside a glass vessel and flushes fines through the sieve, leaving the residue for gravimetric analysis.
