New
multi-function rotators from Grant … November
2003 The
easy to use rotators not only provide vertical spinning (turning the tube end
over end), but they also emulate other manual actions used for mixing in small
tubes; rocking motion has the effect of backward and forward shaking; the
vibration action imitates a light tap with a finger. Rocking angle and speed are
adjustable to facilitate optimum mixing, especially useful with small sample
sizes. Two
models are available each complete with a standard platform. The competitively
priced PTR-30 compact rotator holds up to 22 microtubes, with
speed control over a range from 5 to 30 rpm. The high performance large-capacity
PTR-60 model accommodates up to 48 microtubes, with a variable
speed of 5 to 60 rpm. The
small footprint PTR rotators look great on the bench and are feature
packed, with a simple and straightforward set-up of a multi-segment program,
using touch sensitive keys and a two line display. An integral timer controls
program duration and a useful 5 second pause facility is available, to allow
viscous droplets time to slide down the tube walls. The
rotators are especially suitable for processing small sample volumes, used in a
wide range of tasks in many areas of scientific exploration such as molecular
biology, tissue culture, biochemistry and diagnostics. They are particularly
suited to immuno-precipitations, magnetic bead and affinity matrix separations,
prevention of blood coagulation and latex diagnostic applications. A
selection of accessories is also available to accommodate the ubiquitous 50ml
and 15ml tubes, or tubes of similar diameter. The two rotators form just part of
the exciting new line of Grant-bio ultra-compact personal products. Supported by
the CE mark and a two-year guarantee, they can be purchased worldwide through an
extensive network of approved laboratory equipment distributors. Details
