Laboratory Test Request

Pen Liquid Ink Particle Size and Distribution Testing

Project Description

MULTIPLE TESTS
Contract Laboratory needed for analysis of particle size and distribution in liquid inks. The ink should use pigments as colourant. The ink is water based. We want to compare several different batches, if there were changes of particle sizes, which may cause colour separation during storage of filled pens.
