Choosing a closure for tubes and plates

Push caps and capclusters

Push caps seat with a single press. Capclusters close up to 50 tubes in one movement, which makes a measurable difference when you are processing whole racks rather than individual samples.

Screw caps

Screw caps give a tighter, more reliable seal for freezing and long-term storage, and can be applied manually or with a capper. Match the thread type to your tubes: internal thread caps sit inside the tube and save rack space, external thread caps are easier to grip.
Our screw caps for coded storage tubes come from Micronic, colour-coded for visual sample identification. View the Micronic range.

Sealing films and foils

For microplates, the choice depends on what happens next. Optically clear films suit reading and cycling; foils suit storage and freezing; pierceable films let an automated system access wells without removing the seal.

Not sure which seal fits your plate?

Seal performance depends on plate material, well shape and temperature range. Contact our team with your plate type and application and we will point you to the right product.
