Porvair jgf plate sealing guide

Product catalog summary

Introduction
This document serves as a comprehensive guide on microplate closure and sealing, highlighting various methods and materials to ensure effective sealing in laboratory environments. It underscores the importance of selecting the appropriate closure method to prevent evaporation, contamination, and spillage.

Types of Seals

Thermal Seals: Heat-welded onto the plate surface, these seals form a strong barrier and are ideal for plates with raised rims, particularly those made of polypropylene and polystyrene. They are not easily removable and cannot be resealed over existing foil.
Adhesive Seals: Composed of polymer or aluminium foil with adhesives, these seals are easy to apply and remove. They are unsuitable for assays where adhesive contact with samples is undesirable or with aggressive solvents. Adhesive seals can be applied over existing seals for re-sealing.

Porvair Sciences Products
Porvair Sciences offers a variety of deep well polypropylene plates compatible with different sealing methods, including:

2ml square deep well block with a clear styrene Universal Lid.
1ml and 2ml round plates suitable for thermal sealing.
Rimless versions for adhesive seals or lids.

Closure Devices

Reusable Closures: These include rigid lids and friction seals (cap mats) that prevent leakage and evaporation. Rigid lids are transparent and may feature anti-condensation rings, while friction seals are made from EVA or silicone.
Single-use Closures: These include thermal and adhesive seals, each with specific advantages and limitations.

Sealing Equipment

MicroSeal Manual Thermal Plate Sealer: A compact and ergonomic device designed for manual sealing with a pre-set temperature of 170ºC.
AutoCapper: An electrically operated device that applies even pressure for friction sealing caps, reducing strain and improving reproducibility.
MiniSeal II: A semi-automatic heat sealer with powerful motor control, suitable for various plate types, ensuring quick and effective sealing.

Conclusion
Choosing the correct microplate closure method is essential for maintaining sample integrity and achieving best laboratory practices. Porvair Sciences provides a range of products and equipment to facilitate effective sealing solutions for different laboratory needs.

A G U I D E T O M I C R O P L AT E C L O S U R E A N D S E A L I N G Choosing the correct combination of microplate closure for each type of microplate is important to achieving best laboratory practice and to avoid unnecessary work further downstream. Microplates are a convenient method for storing, transporting and handling compounds and samples, but they have common problems associated with them. Evaporation can occur from the wells of the plate which can affect concentration readings. Contamination from dust, spores or other atmospheric detritus may occur and spillage is a constant danger...

MICROPLATE CAPPERS Mat Capper 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. The Mat Capper can also be used with 2D bar-coded tube racks and their closure mats, including racks containing glass tubes, thanks to the clever design of the...
