DKL 20 lift is much stronger and more durable than what you expect.
It is typically used for lowering and raising automatically a sample rack with twenty standard Kjeldahl test tubes (Ø 42 mm, 250 ml), but it can be used even for other “tougher” applications.
In fact, now DKL 20 can be used also for testing Chemical Oxygen Demand: its lift can automatically manage all the glass required for the COD analysis for processing twenty samples simultaneously.
