For laboratories having to seal medium numbers of micro- and deep-well plates a complete range of non-sticky silicone mats or aluminum heat seals are available – of course a range of thicknesses for several applications is provided and proper sealers to reduce fatique and RSI.
Mat Capper and decapper
For laboratories having to seal medium numbers of microplates the Mat Capper offers an affordable solution. Compact and portable, the Mat Capper is very easy to use, requiring only one operation of the system to produce an accurate and tight seal on a wide range of both collection and shallow well microplates. The seals used are EVA or silicone mats, which work by friction fit and are re-usable with care.
- Caps shallow and deep well polypropylene storage plates
- Needs minimal pressure for capping, reducing fatigue and RSI
- Powder coated to resist chemical spillage
- Universal plate ‘shuttle’ to take shallow or deep well plates
- Fixing holes for securing to bench
The MicroLute™ De-capper is for use with any MicroLute™ plate fitted with a drain cap. It enables the quick and easy removal of the protective lower drain cap, enabling the plate to be used.
Microseal Manual Thermal plate sealer
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.
- Fast warm up time
- Consistent, single action sealing
- Pre-set temperature for ease of use
- Sealing Temperature 170°C
- Warm up time < 10 minutes
MiniSeal II Semi-automatic sealer
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 ther 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 he unit when not in use. Also included is a brass plate weight to keep your foils and seals flat during sealing.
- Desktop semi-automatic Heat Applied Plate Sealing System

- Combined temperature and seal time display
- Light weight system, only 6kgs (14lbs)
- 110V / 220V 50/60 Hz compatible
- No compressed air required
Seals and Foils
Porvair Sciences has a comprehensive range of seals and foils for thermal and adhesive sealing of microplates. In addition, a full range of re-usable cap mats is available for friction sealing of plates.
Foils and seals for the MicroSeal and MiniSeal Plus are supplied as cut sheets, 125mm x 78mm, in packs of 100. All Porvair heat seals have a sealing integrity range of -80ºC to +120ºC, are resistant to DMSO and TFA as well as most other solvents and will seal Polypropylene plates. For Polystyrene plates, please only use Clear Seal.
