VWR Modular Heating Blocks for Tube Combinations Microtube Combination 0.5 Ml Tubes 1.5 Ml Tubes 2.0 Ml Tubes. The combinations of heating and stabilizing elements are arranged in multiple combinations of two or three. The rear of one or both heating blocks can be removed and /or replaced using a service port solder or adhesive bonding agent. Provides surface and depth heating using either a copper wire wound in series with a tubular cable (heating cable) or by using an adhesive tape at the end of a cable. Provides another path for conducting the user's own tubing within the modular system. Excess heat is fed into the tubing by the service ports on the Modular Heating Blocks. Both ends of the tubing are connected to the control box by tubing to which the user can apply any suitable power source. Because the tubing is supported by non-contacting elements the service port eliminates the need for tubular wiring within the tubing and allows the temperature to be precisely controlled.
