Plate sealer is used to seal PCR plates and other microplates during thermal cycling and storage for technologies such as PCR, nucleic acid extraction, and high-throughput sequencing. These consumables reduce sample evaporation to ensure high efficiency and minimal sample loss. Plate seals can come in different varieties and sealing methods. Plate sealing film is made of transparent plastic, allowing the user to visualize the sample. On the other hand, plate-sealing foils are made of thin opaque aluminum that restricts light penetration. Both types can be adhered to the plate by a sealing adhesive applied to the seal or by using heat sealer equipment. Plate sealer can withstand a temperature range of -20°C to 120°C and are typically compatible with automation. Plate covers and gaskets for mechanical seals are also available.

Microplates are very common in laboratories as a convenient experimental consumable for sample storage, transport, and reaction, but they are often plagued by poor seal handling, leading to sample evaporation, spillage, or contamination. Therefore, choosing the correct microplate sealing membrane for your microplates is important to get the best laboratory results and avoid unnecessary work downstream. Heat sealing provides a 100% effective method of sealing well plates, providing a complete seal that is fast and cost-effective to use.

Clear heat seal in the plate sealer is an optically clear laminate film that forms a peelable seal on polypropylene, polyethylene, polystyrene, polycarbonate, and cyclic olefin copolymer (COC) plates. The clear heat seal forms a complete seal over the well plate and can be used for both low-temperature applications (including low-temperature storage) and high-temperature applications such as PCR (when used with pressurized heating caps). The seal is moderately solvent resistant and can be used for short-term storage of compounds at room temperature.

Thermobonded heat seal is a heavy-duty laminate sealing film suitable for providing a very strong but peelable seal that is compatible with polypropylene sheets for a high degree of sample protection. The heavy-duty, strong heat seal film has excellent solvent resistance for storage of ultra-low temperature compounds in DMSO and organic solvents, as well as for long-term room temperature storage, and is therefore recommended for sample transport. The seal can only be pierced with a steel needle sheet or with a perforated platen. The seal can be supplied in sheet form for manual and semi-automatic sealers, or a variety of rolled film forms compatible with specified automatic sealers.

c. Reel formats: a wide range of reel sizes available to suit your choice of automated heat-sealing equipment

For sealing 96-well PCR plates, generally use the transparent film and pressure-sensitive film available in the market, which needs to be sealed with heat to achieve the effect of no leakage and no contamination, with the most suitable temperature setting of 110-120℃. Cold sealing will cause thermal evaporation of PCR reaction solution, which will affect the accurate control of reaction temperature and the concentration of reaction ingredients, and also become a source of pollution.

The sealing of 96-well PCR plates is done by using the electric heating of the instrument to make the plastic film sealing part become a viscous flow and fuse the two layers into one with the help of certain pressure, and maintain a certain strength after cooling. The factors affecting the heat-sealing effect include heat-sealing time, pressure, and temperature.

The 96-well plate sealer usually has both heat seal and cold seal capabilities.

When sealing the film at` about 175 ℃ temperature (usually temperature adjustment from 80 ℃ to 200 ℃) heating + pressure adhesion on the sealing film plate, rapid heating, 60 seconds to 100 ℃, within 3 seconds to complete the heating and sealing film work, remember the heating and sealing film time is too long or too short. The waiting time for heating and sealing film is set according to different aluminum films, usually, the film only needs 3 seconds, too long for heating and sealing film is easy to cause excessive deformation and adhesion of aluminum film fusion, and too short is easily causes aluminum film not fused, of course, by setting the right length of time these problems do not exist. Reasonable design of real-time display of sealing plate temperature. Heat sealing the membrane to prevent a variety of microplates in the detection process of liquid volatilization (evaporation), leakage caused by sample loss, and space cross-contamination of the sealing instrument. The sealed and pollution-free operation, stable heating, solid sealing plate, uniform effect, and the whole automation of heat-sealing membrane. Convenient storage and transportation. Applicable to common tearable film, adhesive sealing film, heat sealing film, puncturable heat-sealing film, optical heat-sealing film, etc.

The role of heat-sealing temperature is to make the bonded film layer heated to a more desirable viscous flow state.

The role of heat-sealing pressure is to make the film already in the viscous flow state produce effective polymer chain segment interpenetration and diffusion phenomenon between the sealing interface, and also make the distance between the polymers close enough to produce the result of intermolecular force.

Heat sealing time refers to the time that the film stays under the sealing plate, which affects and determines the production efficiency and sealing effect of heat sealing equipment.

The cold seal capping function is professionally designed for eight-linked PCR tubes, through the constant and smooth pressure to flatten down the PCR cap, solving the problem of cross-contamination caused by manual capping, leakage, volatile phenomenon, and poor experimental reproducibility caused by uneven effect, and solving the real problem of difficult capping and slow capping. Compared with the traditional manual capping, it automatically detects the height of the adapter, adapts to 0.1ml, and 0.2ml eight-linked PCR tubes can complete 12 eight-linked PCR capping work at one time, real-time display capping time, uniform pressure capping firm, uniform, and consistent effect.
