Gradient thermal cycler, Doppio Gradient, with 2×48-well universal gradient blocks and standard lids for 48×0.2 ml tubes or 24×0.5 ml tubes with flat caps per block
The VWR® thermal cycler family combines high quality engineering with a comprehensive range of block formats. The Doppio, with two independent high speed 48-well blocks in one system, offers the optimum solution for maximum flexibility within a minimum footprint.
Outstanding performance: Thermal plate with impressive thermal characteristics; powerful Peltier elements with Long Life Technology; heat sink with cooling fans with magnetic bearing enabling rapid temperature change control of up to 5 °C/s (3 °C/s for Ristretto)
Reliable, reproducible results: 8, 2×8 or 16 Peltier elements control the temperature row by row, enabling an outstanding block homogeneity of ±0.2 °C and the choice of absolute linear gradients and independent lane control
Simple to use: Sharp, clear TFT display and intuitive touch screen commands
Data control: Up to 4× USB , 1× Ethernet (MS Windows®, Linux), remote control and monitoring of instruments via PC software, MP3 signal tones, user calls via email and master/slave control
All systems include simple to use PC software for remote control and monitoring of instruments, plus creating PCR protocols on the PC.
FlexGradient technology (option for UNO and Doppio only): With the temperature of the 8 rows each individually controlled, select between a perfectly linear temperature gradient (ideal for PCR optimisation), or independent lane control (ideal for the use of different primer pairs in the same run).
System tools at the touch of a button: Graphical or tabular programming, 'Global Program Ramp', 'Gradient Control', 'Tube Control', Emulation mode, online help, 'Quickstart' function and 'Power Fail Denaturation' for auto-restart after power failure.
High specification remote control: State of the art technology, with VWR ‘PCR Cycler Master Software’; receive notifications via email, or use the system MP3 player.
Emulation mode (UNO and Doppio only): For easy transfer of PCR protocols.
Engineered and manufactured in Germany according to ISO 9001, calibrated and maintained according to NIST standards, and backed with more than 20 years of cycler expertise and experience.
