PX1™ PCR Plate Sealer

PX1 PCR Plate Sealer - Amplification | PCR


High Data Consistency with the PX1™ Plate Sealer

Sealing your PCR plate using the PX1 PCR Plate Sealer helps generate reproducible results across 96-well plate

A standard deviation of less than 0.09 cycles in amplification SYBR® Green assays across an entire 96-well plate sealed using the PX1 PCR Plate Sealer demonstrates exceptional experimental uniformity.

Melt curve analysis has a single, consistent melt peak across all wells indicating that there is no inter-well variability in plates sealed with the PX1 PCR Plate Sealer.


Sealing your PCR plate using the PX1 PCR Plate Sealer helps generate reproducible results across a range of template concentration

Amplification data from tenfold dilutions of plasmid DNA (108–102 copies) amplified using different reporter dyes to monitor five targets shows high consistency (A–F). Standard curve generated from A–E demonstrates reaction efficiencies from 90–105% and an R2>0.990.

Intuitive User Interface

The intuitive touch screen makes it easy to program the PX1™ PCR plate sealer. A, high-resolution touch screen presents a button-driven graphical interface to help personalize heat sealing conditions and easily view instrument status; B, the customizable sealing function saves up to 12 unique sealing protocols, eliminating the need to recall optimized sealing conditions.

PX1™ PCR Plate Sealer FAQs

Which heat seal is best for my PCR application?
Use the Heat Sealing Films and Foils table to determine the seal that best suits your experimental needs.


How do I determine the best sealing time and temperature?
Optimal sealing parameters vary according to the heat films and microplates used. We recommend sealing an empty plate using the guidelines found in Suggested Heat Sealing Parameters. After sealing, examine the entire plate for effective sealing and optimize sealing conditions if necessary.


Some of my wells are not fully sealed. What should I do?
Sealing temperature and/or sealing time may be increased to help improve sealing performance. Use an empty plate to optimize seal conditions. See the instruction manual for additional details about seal optimization.


When should I use the sealing frame?
The sealing frame helps secure the heat seal in place and prevents the film from moving during sealing. The sealing frame must be used for the permanent clear heat seal and the peelable foil heat seal.


What happens if I accidently place a seal upside down when sealing?
The PX1 heated platen was designed with an easy to clean, nonstick surface. See the PX1™ PCR Plate Sealer Instruction Manual for directions on cleaning the heated platen. Ensure the PX1 sealer cools for at least 1 hour before cleaning.


Is it safe to leave the heat sealer on when unattended?
Yes. The PX1 PCR plate sealer was designed for reliability and safety. The instrument has an adjustable auto-off feature that automatically shuts the heater off when not in use for a designated amount of time. Simply touch the screen and the instrument will automatically resume heating.


Can I reseal the same plate twice?
A plate sealed with a peelable film may be resealed after peeling an existing film. However, resealing a plate for subsequent use in real-time PCR is not recommended. A plate sealed with a pierceable foil heat seal may also be resealed by sealing another pierceable foil heat seal directly on top. Note: only a single seal can be used in the QX100™ Droplet Digital™ PCR system workflow. Sealing parameters may need to be adjusted.


The current platen temperature is higher than the required sealing temperature. How can I reduce the time needed to reach sealing temperature?
The heated platen cools passively. Opening the PX1 PCR plate sealer drawer can help accelerate the cooling process.


Can I use traditional adhesive or pressure-sensitive seals with the PX1 sealer?
No. Our heat sealing films feature a special hot melt adhesive that effectively seals microplates when used with the PX1 sealer. The temperature and pressure delivered by the PX1 will not successfully seal a microplate when traditional adhesive and pressure-sensitive seals are used.

The PX1 PCR plate sealer provides consistent and uniform sealing across an entire microplate. This semiautomated heat sealer is ready to seal in less than 3 minutes. The PX1 sealer removes human variability from plate sealing and minimizes sample evaporation from the PCR workflow. This versatile instrument is compatible with a variety of heat sealing films and foils and a wide range of PCR plates.

The PX1 PCR plate sealer features an intuitive touch-screen user interface. The thermal sealing process is simplified by allowing sealing temperature and time to be modified with the touch of a button.
