Harp Slice Grids

Harp Slice Grids

ALA’s Harp Slice Grids are ideal for labs who want to save the frustration and wasted time of constructing DIY weights for holding down slices in a recording chamber. These grids (sold in packs of 5) are available in various weights and sizes to suit your experimental requirements. The thin (60-65um) silica fibers are carefully glued onto the inert glass-coated steel rings, with a distance between fibers of about 1mm. This makes it possible to hold the slice down, whilst allowing for easy electrode access during electrophysiology recordings.
The following shapes, weights and dimensions are available:
