Foam Test Apparatus

Seta Foam Dual Twin Foam Test Baths

Part Number 14020-8

Seafoam Dual Twin Foam Test Baths are a pair of highly transparent water baths for detecting undesirable foaming characteristics in lubricating oils, which could cause inadequate lubrication, overflow and cavitation.

The instrument comprises a high temperature (normally 93.5°C) and a low temperature (normally 24°C) bath, each with the capacity to hold four 1000ml graduated glass cylinders.

Each bath assembly comprises an inner glass bath contained in a polycarbonate safety vessel, a top mounted thermostir unit. Please note that DigiFlow mass flowmeters (14012-0) or glass flowmeters (14011-2) are required for testing, these are supplied separately and should be specified at the point of order.

The bath has integral back-lighting with an opaque reflector which aids sample visibility and foam measurements. In addition, the low-temperature bath has a cooling coil for use when the laboratory ambient temperature exceeds the required bath temperature, and two air normalising coils to cool the air emerging from the high-temperature bath test cylinders prior to passing to external volume meters
