1. R2723 Telescopic stand
Particularly stable stand with H-shape base which prevents the stand from tipping backwards.
Additionally equipped with a pneumatic spring stand rod, which enables heavy instruments/ attachments to be raised and lowered smoothly without difficulty, e.g. with rheological measurements using overhead stirrers. The stand has an adjustment screw which can be used to compensate for an uneven laboratory table surface.
