Vertical Multi-Function Rotator

Grant Instruments has introduced a variable speed, variable angle 360º vertical rotator combining three mixing functions – vertical rotation, reciprocation and vibration - into one easy-to-use and highly versatile compact unit.

The PTR-35 - the latest addition to the Grant-bio product range - is designed for vertical mixing applications including hybridization reactions, cell growing, homogenization of biological solutions, prevention of blood coagulation and latex diagnostics.

The PTR-35 is supplied with a standard platform that has capacity for up to 26 x 15mm diameter tubes or 26 x 1.5ml - 2ml microtubes. It can also accommodate longer tubes due to its high platform position. An additional four optional platforms provide the flexibility to mix and match different tubes sizes (15mm and 30mm diameter) and tube capacities (1.5ml to 50ml).

All of the PTR-35’s mixing functions are fully programmable - including a pause option - and can be set for continuous or timed operation (1 min to 24 hours) to achieve optimum mixing either in a single mode or in any different combination of the three functions. The unit boasts vertical rotation speeds of 10-100 rpm, a 15-90º reciprocal turning angle, and can be programmed in 1 to 5 second vibration bursts.

The Grant-bio PTR-35 unit measures 195 x 155 x 365mm (h/d/w), features a 2-line 16-character LCD display and a reliable and exceptionally quiet motor. As with all of the Grant-bio range of life science products, the PTR-35 is robust and reliable, offers exceptional value for money, and comes with a 2-year warranty.

For customers that need a higher capacity multi-function rotator, the Grant-bio PTR-60 is available and can accommodate up to 48 x 15mm diameter microtubes.
