Sealing Parameters

Technical data and parameters for heat sealing laboratory plates:

Product Code	Product Name	Dwell time and temperature for a 96 well plate	Dwell time and temperature for a 348 Well Plate
4ti-0541	Clear Seal	TBC	TBC
4ti-0575	Clear Weld Seal Mark II	TBC	TBC
4ti-0581	Clear Seal 3730	TBC	TBC
4ti-0521	Peel Seal	TBC	TBC
4ti-0587	DMSO Resistant Peel Seal	TBC	TBC
4ti-0531	Pierce Seal	TBC	TBC
4ti-0536	Foil Seal	TBC	TBC
4ti-0591	Thermal Bond	TBC	TBC
4ti-0527	Black Seal	TBC	TBC
4ti-0595	Gas Permeable Heat Seal	TBC	TBC

These values are for guidance only. It is advisable to conduct individual trials depending on the plate type being sealed.

These values are for sealing with the semi automatic 4titude® 4s2™ Thermal Sealer (4ti-0650). If using an automated sealer, reduce the dwell time by 0.5 - 1.0 second.

Certain seals such as the Peel Seal are prone to curling prior to sealing. To overcome this issue, place a weighted metal sheet (4ti-0602) over the seal prior to sealing to keep the seal flat. If this item is being used, increase the dwell time by 1 second.
