Nunc™ Well Cap Mats
By Nunc
For sealing of polypropylene and polystyrene plates, these cap mats provide an efficient seal with minimum protrusion into each well. Pierceable to hypodermic needles and self-closing. Use for chemical and compound storage to prevent evaporation and dust. Silicone pre-slit well caps permit a pipet tip or probe to enter the well without damage to the cap. Can be used at temperatures down to -80°C (except Silicone cap, Cat.No 82-276011, -20°C).
