Biometra Tank-Blotting

Biometra Tank-Blotting Biometra Tankblot Eco-Line - Gentle blotting of challenging proteins

  • Modular Tankblot system for blotting and electrophoretic applications
  • Maximum transfer efficiency for large and native proteins
  • Simultaneous blotting of up to 4 gels

Product Details

The Tankblot Eco-Mini and Tankblot Eco-Maxi are part of the modular Eco-Line product series, which allows 2 or 4 gels to be blotted simultaneously.  The ultra-pure platinum electrodes are specially arranged on the side walls of the buffer tank to ensure uniform and reproducible transfer over a wide range of molecular weights. Profit by the unique design of the EBC buffer tank. Through the connections for an external cooling unit, the gels can be continuously cooled during the blotting process, the ideal prerequisite for a gentle transfer of temperature sensitive, native or very large proteins (> 100 kDa) even with long transfer times (> 24 h).

  • Special electrode configuration for a homogeneous electric field
  • High user comfort through color-coded blot cassettes
  • The integrated cooling option (water circulation system) guarantees constant buffer temperature

The Electrophoresis Module for Eco-Mini and Eco-Maxi are available separately and will convert the corresponding tank blotting systems into powerful PAGE electrophoresis systems.

Tankblot Eco-Mini
Tankblot Eco-Mini is designed to transfer up to four PAGE mini-gels (up to 9.5 cm x 8.5 cm) in separate blotting cassettes simultaneously. The special design of the blotting cassettes allows easy assembly and loading into the blot module. Additional the assembly defends blotting sandwiches from squeezing.

Tankblot Eco-Maxi
Tankblot Eco-Maxi is the large version for gel sizes up to 22 cm x 19 cm. The system offers the capacity of multiple transfers: several small gels or 1 large gel per cassette. Up to 2 large gels can be transferred simultaneously in separate blotting cassettes. The special design for fixing the blotting sandwich in the blotting cassette prevents squeezing and allows easy handling.
