Microplates and PCR Consumables 14 n web: www.alphalabs.co.uk Plate Seals for Microtitre and Deep Well Plates Adhesive sealed films and foils can offer more permanent sealing and unlike lids and sealing mats which are for general use, films and foils are application based in their design and provide protection against evaporation, condensation, oxidation and cross contamination during processing, storage and shipment. Our application guides can help you choose the right seal for your particular application. Adhesive seals are easily applied by hand using a sealing roller or paddle, making them ideal for use where smaller numbers of samples are processed. They are also available in roll format for use on sealing machines that can apply pressure without a high temperature for use where samples are heat sensitive and the throughput is high. Applications Applications for sealing films mirror the applications for multi-well plates and tissue culture plates that have become ubiquitous in today’s laboratories. These include enzyme-linked immunosorbent assays (ELISAs) and polymerase chain reaction (PCR) methods for amplification of nucleic acids for analysis and quantification, both classic and real-time. Other films are designed to support manual and robotic processing and storage of samples in high-throughput screening (HTS), to maximise signal to noise in fluorescence and luminescence assays, and to promote uniform gas exchange in cell and tissue culture procedures. PCR and qPCR - Our extensive range of seals includes films for PCR and qPCR, which offer better adhesion and combine an optically transparent polyester sealing film with a strong, ultra-smooth, non-absorbing medical-grade adhesive for superior performance in realtime PCR applications. In addition to films, we also offer PCR Foils. Other Applications - Designed for both long- and short-term storage, other films support manual and robotic processing of samples, maximise signal to noise in fluorescence and luminescence assays, and promote uniform gas exchange in cell and tissue culture procedures. With high throughput HPLC systems using solvents, getting a good seal can be problematic. Alpha Laboratories have sealing films with special features which avoid tip fouling and strong solvent resistant adhesives, making them particularly suitable for this application. Our guide overleaf can help you choose the right seal for your particular application. For sealing film accessories please see page 129. Plate Seals for Microtitre and Deep Well Plates Microplates are a standard tool in bioanalytical research and clinical diagnostic testing laboratories. They are used in virtually every Life Sciences application as they simplify the handling of large numbers of samples and enable automation. Several types of sealing systems are available and different techniques and products can be used including adhesive and heat sealed films and foils, sealing mats and plate lids. The preferred method for sealing microplates, heat-sealing, creates an airtight chemically-resistant seal without the complications of using adhesives for the application. Available with application specific features in individual sheets or rolls, our range of heat sealed films are suitable for numerous low, medium & high-throughput needs.
