BTH 20

Block tube heater

BTH 20: white housing, a square chamber with a black gasket on top and a red-framed touchscreen on the sloped front

Heats follicular fluids and oocytes in test tubes up to 37°C and maintains a stable temperature at 37°C.

Two-dimensional heating

Not only from below, but from the sides.

Using a heating film resistor, the BTH 20 warms the block chamber not only from the bottom surface but also from the side walls, ensuring safe and homogeneous heat distribution.

Designed for use in OPU operating rooms and embryology laboratories.

Schematic cross-section: the block chamber is heated from the bottom surface and both side walls; a block holding test tubes sits in the chamber.

Operation

Alerts when time is up, shows the overrun.

  • Automatic start-up

    The user-friendly BTH 20 control panel is equipped with a timer function for automatic operation. It ensures the device is ready at the desired temperature when you enter the laboratory.

  • Timer

    Initiates a timer for sperm analysis and other time-dependent procedures without requiring an external device, providing both audible and visual alerts once the set time has elapsed. If the defined duration is exceeded, the elapsed time is displayed on the screen.

  • Safety and ease of use

    The BTH 20 block tube heater with an integrated control panel operates at low voltage, ensuring user safety. Its 3.2″ resistive color TFT touchscreen provides easy operation and can be conveniently used while wearing gloves. It is resistant to liquid spill risks.

  • Fast heating and data transfer

    Thanks to its high thermal conductivity aluminum structure, it reaches 37°C from room temperature in less than 30 minutes. Real-time temperature data can be transferred to a computer using the cable supplied with the device.
