Description
This used semidry blotter Amersham Biosciences TE 77 PWR is a high-quality semi-dry transfer unit designed for fast and efficient electrophoretic transfer of proteins from polyacrylamide gels onto membranes for Western blotting applications. The system is widely used in molecular biology laboratories, biotechnology facilities, pharmaceutical research, and academic laboratories where reliable protein transfer is essential. The TE 77 PWR is suitable for gels up to 21 × 26 cm and can also accommodate up to four side-by-side mini gels, making it ideal for both standard and higher-throughput blotting workflows. It features a built-in power supply, eliminating the need for an external power source and simplifying operation.
The unit operates with low current and low voltage transfer, minimizing Joule heating and reducing the risk of membrane damage. One of the major advantages of the PWR version is its automatic stopping feature: the instrument monitors transfer stack resistance and stops the transfer when buffer depletion is detected, helping prevent overheating and failed transfers. This greatly improves reproducibility and protects valuable samples. The perforated platinum-titanium and stainless steel electrodes provide uniform, contamination-free transfer and long service life. Most transfers are completed within one hour or less, making the TE 77 PWR a highly efficient solution for routine protein blotting.
