The CR1224 is the standard sandwich cover used for 24-deepwell MTPs. For longer cultivations, the CR1224a cover can be considered to limit evaporation even further.

Other characteristics of the covers:

• The sandwich cover its function relies on the vertical force applied by a clamping system such as CR1801h or CR1700
• Autoclavable and thus reusable many times
• The cover has a blue and green filter to prevent airborne contamination
• The 5mm thick silicon layer is made from very durable rubber, which is free of any animal product
