Hoefer Semi-Dry Transfer Units with Built-In Power Supply TE77XP

TE77XP Semi-Dry Transfer Unit with Built-In Power Supply is a semi-dry electrotransfer system that rapidly and efficiently transfers proteins from polyacrylamide gels onto membranes (nitrocellulose or PVDF). The unit uses an intelligent internal power supply that monitors transfer status and stops the run before the stack overheats, and supports up to two layers of gels for simultaneous transfers. Primary use cases are protein blotting workflows requiring rapid transfers with minimal buffer consumption and reduced stack heating.

Key Features:

• Transfer area: 21 x 26 cm (supports up to 12 mini gels)
• Built-in power supply with maximum settings: 30 V, 500 mA, 15 W
• Maximum temperature: 45°C; operating environment 4 to 40°C, humidity up to 80%
• Unit dimensions (W x H x D): 38 x 46 x 9 cm; unit weight: 7.40 kg
• Electrodes: platinum-coated titanium anode and stainless steel cathode with iridium oxide finish; vented electrodes
• Includes consumables: blotting paper (21 x 26 cm, 25 sheets), porous cellophane (20 x 35.5 cm, 50 sheets), Mylar masks (23 x 27.5 cm, 2 pcs)

Advantages:

• Intelligent built-in power supply prevents stack overheating by monitoring transfer status
• Requires minimal current and generates less heat, reducing risk of transfer stack drying and transfer interruption
• Vented, durable electrodes (iridium oxide and stainless steel) provide contamination-free, consistent transfer and prevent bubble buildup
• Minimal buffer requirements lower reagent use and preparation time for blotting workflows
