ZAP™ Low-Retention

The ZAP™ Premier Low Retention tips have all the benefits of the ZAP Premier tips but also provide up to ten times less fluid retention than standard tips.

The low retention tips have been constructed with a diamond polished mould surface. The unique resin formulation used in these tips increases the hydrophobicity of the tip surface.

This is particularly useful when working with biological samples as the increased hydrophobicity encourages proteins to fold onto themselves and expel cleanly from the tip surface. This results in less fluid retention, less sample loss and clean liquid release so that evrey last droplet of your sample is dispensed.
