The PTR-35 and PTR-60 variable speed, variable angle, 360° multifunction rotators provide flexible mixing options in a compact unit. Applications include mixing mictrotubes, immunoprecipitation and other affinity matrix applications, preventing blood coagulation and latex diagnostics. The stepper motor produces regulated and reproducible rotating throughout the speed range. The rotators provide all that is needed for mixing different sized particles.

• Multifunction: rotation, reciprocation and vibration
• All actions can be set for continuous or timed operation, integral timer: 1 min. to 24 h with automatic switch off
• Individual phases can be linked together for flexibility
• Can be used at 4 to 40 °C (80% relative humidity, non-condensing), in an incubator or cold room

360° long wave required by large particles.

Reciprocal long and medium wave ideal for large to medium particles.

Vibration short wave suits small particles

Combining different phases in a customised sequence gives the following possible combinations: 360° vertical rotation; 360° reciprocal; 360° reciprocal and vibration; 360° reciprocal and pause; reciprocal; reciprocal and pause; vibration and reciprocal. An individual program may be configured for any different combination of components to ensure optimum mixing conditions.
