TMC - 75 Series Lightweight Breadboards  
TMC 63-500 Series Tables

TMC's 75 Series Breadboards
minimize both weight and cost. A patented manufacturing technique allows TMC to form countersunk, tapped holes in a thin top skin of stainless steel. The holes are not drilled or punched, but fabricated in a way that effectively “thickens” the skin in a small ring around the threads. No inserts are used and the tapped holes are 3 threads deep.

These tops have relatively high levels of rigidity, as they utilize TMC's standard steel core. However, with their thin top and bottom skins, they cannot have the rigidity and damping properties of TMC's 78 and 77 CleanTop® II Breadboards.
They are ideal when light loads are anticipated and low weight and/or cost are the most crucial factors.

The weight savings - 50% less than TMC's 78 Series Breadboard - is derived only from the lighter gauge skins.

This lightweight design is available from stock in the sizes listed below. A full range of sizes and materials is available on a custom basis. Contact Harvard Apparatus Canada for pricing and delivery for custom configurations.

Options and  Accessories
Breadboard Leveler
As an option on 2 in. (50 mm) thick breadboards with 1/8 in. (3 mm) or 3/16 in. (5 mm) skins, TMC provides a breadboard leveler mechanism. The leveler consists of a threaded sleeve bonded into the top, a bushing leveler, and a locknut. An M6 or 1/4-20 bolt may then be used to fasten the breadboard to another top. The leveler is adjusted and locked with a simple Allen wrench.
