| The Grant-bio PTR-30 and PTR-60 multi-function rotators provide all that is required for thorough mixing of microtubes, for reproducible sample preparation:
360° vertical rotation
reciprocal rotation, turning angle from 15° to 90°
vibration, settable in a burst of 1 to 5 seconds
5 second pause
all actions may be set for continuous or timed operation, and individual phases may be linked together for absolute flexibility:
360° vertical rotation
360° and reciprocal
360° and reciprocal and vibration
360° and reciprocal and pause
reciprocal
reciprocal and pause
vibration and reciprocal
Designed to meet the challenge of workspace restrictions, the Grant-bio vertical rotators are compact, with a low profile and small footprint, fitting neatly into the smallest workspace. They are also extremely quiet.
Small but highly functional, the stepper motor produces regulated and reproducible rotation throughout the speed range and, combined with the sturdy construction, will guarantee years of consistent operation.
The Grant-bio vertical rotators are quiet and extremely easy to operate, with very simple set-up of a multi-segment program, using the two line set-up and status display.

PTR 30, 60 360° vertical multi-function rotator

Mixing of small volumes is extremely difficult due to surface tension of viscous liquids, but insufficient mixing can lead to a high percentage error. 360° vertical rotation (turning the tube end over end) has a highly efficient mixing effect. The Grant-bio PTR-30 and PTR-60 not only provide 360° vertical rotation, they also emulate other manual actions used for mixing in small tubes: reciprocal rotation has the effect of backward and forward shaking, a brief pause allows droplets to slide down the tube walls, and the vibration motion emulates a light tap with a finger.
The goal of mixing is to produce a uniform and reproducible mixture from an assortment of components of different size and characteristics. In spite of considerable interchangeability, the correct kind of movement is often critical and can affect the outcome of an experiment or a diagnosis. One of the key criteria is the particle size of each component, as this determines which type of ‘wave’ motion is needed to produce adequate mixing for that particular component:
small particles require short wave motion
medium size particles require medium wave motion
large particles require long wave motion
A short wave motion, for example, will have very little effect on large particles.
The 360° vertical rotator provides all that is needed for a mixture of different sized particles:
| 360° vertical rotation |
long wave |
| reciprocal action |
long and medium wave |
| vibration |
short wave |
and a dedicated program may be configured for every different combination of components, to produce the correct result.
Applications
Suitable for 360° vertical mixing applications in many different fields, with specific applications including:
immunoprecipitations and other affinity matrix applications
prevention of blood coagulation
latex diagnostics
