The Makler counting chamber is 10µm deep, which is one tenth the depth of other Haemocytometers, making it the shallowest of known chambers. 

This quality chamber is constructed from two pieces of optically flat glass: the first is the chamber, the second the cover glass which has a fine grid pattern of 1mm squares and a centre area further subdivided into 0.1mm squares. Four quartz pins of precise height hold the cover glass to give an exact trapped specimen depth of 10 µm
