Let's say if only 50k cells are attached onto coverslip, then you should just plate 50k cells in the 6-well for gene expression. This is contrast to what Ron Hrstka has suggested.
Closed Cell Description: Closed Cell , also known as Polyethylene , is an excellent quality type of in which the individual cells are sealed off from one another, preventing the passage of air and water through the material and making it impermeable. The closed-cell structure results in a that is rigid and buoyant.
Froth flotation using a mechanical cell is the key beneficiation approach for high recovery, mostly below 150 μm, depending on the nature of the ore, and below 70 μm for base metals (Jameson, 2010, Nguyen and Schulze, 2003); however, the recovery of coarser particles diminishes with increasing size of the particle due to high turbulence near ...

Safari et al. (2016b) showed why some flotation cells operate at high energy input and have high performance for fine particles; some flotation cells operate at low energy input and have high performance for coarse particles. The OGC was tested in a wide range of particle size fractions up to 650 µm.
1. Introduction. One of the major challenges faced by the resources industry is the poor separation of fine gangue particles from value particles in froth flotation (Wills and Finch Citation 2016).In a flotation cell, normally the value particles are rendered hydrophobic and then attach to air bubbles and rise to the top of the flotation cell as particle-bubble aggregates …
Since in reverse flotation the initiation of strong convective flows in a flotation column leads to the decrease of the concentrate quality, it makes sense to use several series-connected ...

Too high or low pulp density can reduce flotation efficiency and gold recovery. Flotation equipment. The design and characteristics of the flotation cell or machine can impact the flotation process. Agitation speed, cell geometry, and bubble size distribution can influence flotation performance. Water quality
The change of flotation feed size leads to new challenges in designing flotation equipment and circuits. For conventional flotation circuits, a typical feed size is in the range of 75–150 μm (Jameson, 2010b).As described in the famous 'elephant curves', for most of the base metal sulphide minerals, this size range provides the highest recovery in conventional flotation …
Some scholars also use the sweep factor (SF) to represent the collision probability (Frankiewicz et al., 2005; Lee and Frankiewicz, 2004; Sylvester and Byeseda, 1980), SF = (A gas F gas)/A cell is the cross-sectional area of the flotation cell (m 2), F gas is the gas volumetric flow rate (m 3 /min), A cell is the cross sectional area of ...

It is possible to increase the rise rate of the formed flotation aggregates, and thereby enhance the efficiency of flotation treatment via secondary saturation of the flotation cell with d b = 0.1-0.3 mm air bubbles. The air bubbles of 0.02-0.07 mm diameter float up in laminar flow regime but create light turbulence in the flotation cell.
