The D-LAB vacuum pump series was developed specifically to satisfy the exacting standards, reliability and ease of use demanded in today's laboratory applications. Diaphragm pump technology has proved itself during re- cent decades and the D-LAB range is a logical continuation With six different pumping capacities and having facilities for modular expansion, a D-LAB pumping system can be optimised for any application. * Vacuum filtration * Vacuum distillation * Vacuum drying * Rotary evaporation * Pumping and transferring of gases Item Description 2.

3. Assembling or Upgrading your 3.1 Mounting the pump to the Baseplate Basic requirements for the assembly of a D-LAB-system are a D-LAB pump and a Baseplate. The mounting-system allows interchange of pump types on the baseplate without For mounting a D-LAB-pump to the baseplate the pump must be equipped with a mount (two components). Baseplates ordered separately (see 9.3 Accessories for the D-LAB) will contain the mounts. Installation of the mounts on the pump: a. Unscrew the pump's rubber feet anticlockwise; b. Install the mounts onto the pump according to figure 6. a. Stand the pump...
