MM 33 

Micromanipulator

Marzhauser

 


MM 33, for right hand use, mounted on  a 1/2" rod

The MM 33 is the right choice for tight environments which require maximum versatility within a small space. Stainless steel cross-loaded roller bearings are designed to offer low friction and smooth linear motion with minimum side play.  The preloaded rollers are set at 90 degrees to the hardened steel guides ensuring constant contact and accuracy.  This precise rack and pinion drive gives stable, drift free movement with minimal backlash.  The controls are placed one above the other which makes for less hand movement and easier positioning.  The scales for all axes are calibrated in 0.10mm increments and the fine micrometer adjustment for the X-axis thrust is calibrated at 0.01mm with estimates to 5µm.
The MD 4 is comparable to the MM 33, yet it has a second tool holder. This extra tool holder can independently travel in x- or y- direction, as well as swivel. It has two fine-adjustment screws.

   MM 33 with 45° tiltable X-axis, for left hand                      MM 33 with 90° tiltable fine movement  (SPT)                        MD4 mounted on a tilting base 
   use,   mounted on a rotating base (Sutter)


The MM 33 and the MD 4 are  available for both right hand or left hand use. For further flexibility the MM33 can be mounted on a rotating base (Sutter) and  both can be mount on a tilting base (Marzhauser).

The optional rotating base also has  a stepwise  tiltable X-axis. The rotation in the horizontal plane (approximately 120 degrees) has a positive stop, quick release mechanism for fast insertion and  removal of pipettes. The second rotating axis allows the MM 33  to be tilted in the vertical plane from 0 to 70 degrees.

The optional tiltable X-axis allows the fine axis to be tilted stepwise up to 45 degrees. An optional vertical lock is also available for locking the position of the vertical axis. These options should be ordered at the time of purchase since the modifications are factory installed. For tilting  the fine movement device of the MM 33 in a desired angle between 0 and 90 degrees a small tilting base (SPT) is also available.  

To avoid a drift of the manipulator whilst working with a higher load, the MM 33 can be delivered with an additional brake for the Z-axis ( Z-axis stop ).
