Positioning is critical to gain accuracy while retrieving from the micro-trough, Critically align your worksurface. When writing a method the initial configuration should include this definition on the worksurface. Although the pull down graphic appears as a Vertical Quarter, it will operate as intended. Total volume per ea. section is 6000 ul. Volume of the sub-trough is 10ul. Liquid Level sensing may not perform appropriately under all conditions however adjustments can and should be made or standard vertical 1/4s should be used under those conditions. Minor adjustments to Depth and Height may be required from system to system or from other reservoir holders like the chillable holder.
