TumblIR Sampling Accessory 
The dedicated TumblIR sampling accessory is a proprietary liquid 
transmission sampling accessory designed and manufactured 
exclusively by Agilent to optimize the analysis of many liquid, paste 
and gel samples. Compared to traditional liquid cells for general 
analytical laboratories, the TumblIR makes it much easier to prepare, 
load, analyze and clean the sample.  
The TumblIR operates in two modes: sample loading/cleaning, and 
sample analysis. 
In the sample loading and cleaning mode, the TumblIR is rotated so 
the sampling window is facing up. In this position, the sample 
mounting area can be easily accessed for loading the sample into place 
and for cleaning the sampling surfaces before the next sample is 
analyzed.
