After fitting the washer to a filter flask, an inverted sample tube is inserted into the washer and solvent is introduced into the reservoir using a series of wash bottles. You can perform numerous wash steps and finish by pulling air through the tube to complete the procedure. Filter flasks are...

Authentic Bruker® SampleJet® cap without code, up to 600 MHz. Do not use with Ceramic spinners.

Shigemi tube features a susceptbility matched bottom and plunger for each of the following solvents: CDCL3 CD3OD D2O DMSO-d6 This feature would effectively reduce the boundary gradients at the edges of the coil. Therefore, it is no longer critical to keep the general NMR sample rule as "sample...

Designed by Dr. H.R. Krouse, University of Calgary, for use with 7408 in H2O18/H2O16 determinations. CO2 from the equilibration flask is transferred to the sample tube for isotopic analysis. Unit consists of PTFE plug with FETFE O-Ring and glass vessel with 5mL tube at bottom.
