Leto izdelave: 2024, stanje: novo, The TS 500 is a high-performance heavy-duty screening machine specifically designed for analytical sieves up to 450 mm in diameter. Where laboratory sieve shakers quickly reach their limits, the TS 500 screens or separates quickly and reliably thanks to its enormous power reserves. The unique design and construction of the screening machine ensure that the entire energy is transferred directly to the sieves and sample. The design allows the machine to operate virtually silently, while the robust construction is ideally suited for the harshest environments. The screening machine is designed for a sieve stack up to 1,000 mm. The high-performance screening machine comes equipped with a mobile control unit and extension cable for attachment to a wall or workbench. Iodsgkrxrepfx Al Nstf
