Of the various methods for sealing microplates, heat sealing has become the preferred option. It creates an air tight and chemically-resistant seal without the complications of adhesives being applied to a plate. Porvair Sciences has developed a range of units to meet the needs of low, medium and high throughput laboratories for microplate sealing.
The MicroSeal is designed to be compact, easy to use and ergonomic. Heat sealing a wide range of plates is quick and simple. Heat sealing protects precious samples from evaporation and contamination when performing PCR or during storage. A built-in thermostat prevents overheating of the MicroSeal and with its small footprint and ease of use, the new MicroSeal is the obvious choice for manual sealing of PCR plates and microplates. With a pre-set temperature of 170ºC, ideal for most common sealing applications, and dual LED status display for power and heating, the MicroSeal is safe and easy to use. An ergonomic pull down action allows single action sealing of most common plate types. Additional adaptors are available for specific plates.
The new MiniSeal II semi-automatic plate sealer builds on the reputation of our earlier Minseal design for robustness and an ability to seal most types of plate. For users who need a tight seal on deep well plates, conventional sealers may not offer sufficient down force to guarantee a good seal.
With powerful stepper motor control and a mighty 450 watts of heating power available, the new MiniSeal II copes effortlessly with PCR, filter-bottomed, assay and deep well plates, EVEN if the plate itself is distorted or bowed. Easy to set up with simple up/down programming for both sealing time and sealing temperature, the MiniSeal II also boasts a robust drawer design that ensures excellent conformance to health & safety regulations.
With so much available power, sealing times for most polypropylene plates with Porvair seals are less than 3 seconds each. Sealed plates are automatically ejected from the MiniSeal II. With a footprint smaller than a sheet of A4 paper and weighing just 6kgs, this electrically-driven sealer is ideal for small bench spaces.
Unlike some other manufacturer’s products, MiniSeal II comes complete with plate adaptors for standard SBS microplates, deep well microplates and PCR plates. The unused adaptors are ingeniously designed to stack on top of the unit when not in use. Also included is a brass plate weight to keep your foils and seals flat during sealing.
