Used in combination with contact plates, the contact weight enables the standardisation of microbiological surface control between operators. It applies the same constant pressure for a pre-set time on a contact plate. This ensures results are directly comparable. The contact weight meets the ISO 18593 standard, and has a sterilisable stainless steel base and pull-out digital timer.
