The Mini Super HT PAP pen draws a water repellent circle around slide mounted tissue and prevents the waste of valuable reagents by keeping the liquid pooled in a single droplet. The pen has a 2.5 mm tip and can be used to draw about 400 applications. Also see the larger Super HT PAP Pen with 4 mm tip.
