Super HT PAP Pen

The Mini SuperHT 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 Mini SuperHT PAP Pen has a finer 2.5 mm tip, and can be used for about 400 applications. We also offer the regular size SuperHT Pap Pen, which has a 4 mm tip and can be used for about 800 applications. SuperHT Pap Pen barriers are insoluble in aqueous buffers, detergents, alcohol and acetone, but can be removed with xylene. Barriers are stable at temperatures up to 120°C.
