at last there is a safe way to store those precious specimens or
genomic library cultures in microplates and not worry that they
will freeze dry or get contaminated. No sticky tape residue in
your wells, no condensation "cross talk" and no
spilling the plates taking the tape off. Simply place the SEAL & FREEZE gasket on the microplate,
replace the lid, and compress the plates together in a bundle
with hook & loop straps, cable ties or rubber bands. You can
combine from 1 to 12 plates in a single bundle. This is also a
great way to protect plates during frozen shipment.
The heart of the SEAL & FREEZE SYSTEM is the
gasket. This gasket is made from a special closed cell silicone rubber
material that can withstanding autoclaving and does not get brittle at -70C.
In addition to being useful in cold storage, it can also be used to seal
microplates used with our
VP 740 series heating
Note that we have clipped off 3 of the corners so the gasket will fit on
almost all of brands of microplates. Although the microplate
manufactures try to make plates that only their accessories will fit, we can
usually find a way around their attempts at monopoly.
The SEAL & FREEZE
consists of a special autoclaveable foamed silicon rubber gasket
(VP 632) that seals the whole top of the microplate. The gasket
is fixed to the plate lid so that it can be removed and replaced
in exactly the same position multiple times. The wells can be
unsealed and sealed by simply removing and then replacing the
lid. Spacers (VP 640) are placed on top of the lid to distribute
the compression force from the cable ties evenly over the whole
surface of the lid. Plates and spacers are stacked up to 12 high
and then placed on a bundle bottom (VP 650). The bundle top (VP
651) is added and two cable ties (VP 624) are placed around the
bundle and tightened with a cable tie gun (VP 670) to compress
the gasket material and seal the wells. To access the plates
merely cut the cable ties with a cable cutter (VP 680). Reusable
Hook & Loop Straps (VP 618 & 625) are perfect for bundles
that are sampled multiple times and stored below -20°C.
bands (VP 619) may be substituted for cable ties when the plates
are stored at 4°C or for short periods at -20°C. Rubber bands should not be used below -20°C.

components of our SEAL & FREEZE
