I didn't expect that a simple eight-tube PCR tube could hide so many 'little tricks'! What are the differences between the different types of PCR eight-tube strips?
This article will introduce you to three common types: sheet cover type, chain cover type, and independent cover type.
Among them, A-Gen’s upgraded eight-piece PCR tube with a sheet cover has better adaptability. It can not only accurately fit the experimental instrument, but also greatly improve the operational adaptability and make the experimental process more stable and smooth~
PART-01
Flaky cover
Core features
·One-open, full-open design: The switch cover of eight consecutive tubes can be completed in a single operation.
· Flat cover surface: The surface is smooth and has no bulges, making it easy to mark sample information with a pen. It is suitable for flat cover PCR instrument heating modules.
Operation suggestions
When opening the cap, place your thumbs against the edge of the tube cap and gently turn it upward 45° to avoid excessive force that may cause the tube to topple over.
PART-02
chain cover
Core features
· One hole and one cover are independently sealed: Each tube cover is independently sealed, greatly reducing the evaporation rate.
· Cuttable tube body: There is a pre-break design between the connecting tubes, which can be cut into a single tube or 2/4 connecting tubes as needed, suitable for small-flux reactions.
· Low temperature resistance: -80°C and repeated freezing and thawing for many times still maintain good sealing, suitable for long-term sample storage.
· Suitable for fluorescence quantitative PCR (qPCR/RT-PCR) and precious RNA sample storage.
Operation suggestions
· Manual closing: first press both ends of the tube cover until you hear a 'click' sound, and then press from both ends toward the center to ensure that the sealing ring is fully fitted.
· Batch processing: Equipped with an eight-tube decapper, it can process 96-well plates at a time, shortening the operation time by 60%.
· It is recommended to tilt the tube body 30° when opening the lid to avoid splashing of liquid in the tube due to surface tension.
PART-03
independent cover
Core features
· Separation design of tube cover: The cover and tube body are completely independent, eliminating vibration transmission contamination when the tube is opened, and at the same time, it facilitates flexible opening and processing of samples.
· Suitable for precious sample storage and recovery experiments.
Operation suggestions
Use special cap-opening tools to avoid contamination caused by fingers touching the inside of the cap.
PART-04
Opening operation
Closing operation
·Pre-alignment: Ensure that the tube cover and tube body are positioned accurately to avoid misalignment.
·Fix both ends: First, press both ends of the tube cover with your thumb and index finger to the sealing position.
·Center reinforcement: Press sequentially from both ends to the center to form a continuous sealing surface.
·Tightness check: Gently pinch the tube body to see if bubbles are overflowing, or turn it upside down for 10 seconds to check for leaks.
#A-Gen BIO’s PCR eight-tube tubes are made of imported medical-grade polypropylene (PP) material. This material has excellent resistance to repeated high and low temperatures. It can stably cope with the high-temperature environment during PCR amplification and the low-temperature conditions of sample storage before experiments.
