Set of the 3 metal parts with designs that mimics those of the parts from the Thermo Fisher Vitrobot dewar set, work seamlessly with the NanoSoft or Thermo Vitrobot dewar with equal performance.
 
Our Grid Box Ring sits at the same height as the Vitrobot version (so grid boxes sit at same depth into dewar) but is slightly thicker and remains in contact with liquid nitrogen longer if the nitrogen level gets low.  Our ethane cup dimensions mimic those of the Vitrobot ethane cup, and the spider as well. We offer these parts that perform just as well with the Vitrobot, but at a more generous price than other options.
