The CombiClover 4 Chamber Crystallization plate utilizes four partitioned reservoir chambers in the place of one central reservoir. These four partitioned chambers are each connected to a satellite drop chamber via dedicated vapor diffusion channels to create a variation of the novel combinatorial "crystallization clover" provided in the plates. Each plate has 24 of the partitioned reservoirs and 96 flat-bottom sitting drop chambers. This design allows four different experiments to be conducted in each clover, with each portion containing a different crystallany, and allowing them to be investigated simultaneously.

-Plate dimensions are 112.0mm x 165.0mm x 24.0mm

-The capacity of each of the four partitioned areas of the reservoir is 250 microliters

-The satellite drop chamber volume is 50 microliters.

Pack of 40 plates.

This product was formerly called CompactClover

Abstract  Quantum chemistry method was used to calculate the geometry structure of heavy oil character molecule. The method to calculate the minimum cross-sectional diameter of heavy oil character molecule and to show the molecular dimension was brought forward, which was used to predict the minimum cross-sectional diameter of some typical heavy oil character molecules. It is shown that the theory calculated result was consistent with experimental date. The minimum cross-sectional diameters of Daqing first cut (DQ-fcut) , middle cut (DQ-mcut) and end cut (DQ-endcut) were 1.8703, 3.0080 and 3.4929nm, respectively, meaning that these kinds of heavy oil molecules are too big to enter the sieve pore of zeolites, so they could be only cracked on the surface of zeolite. These research results can offer some useful theory basis to the selection and synthesis of zeolites.
