G-Storm GS2 Multi Block Thermal Cycler

Thermal Cycler Systems

The G-Storm GS2 is the perfect Multi Block Thermal Cycler solution for laboratories that require medium to high throughput performance or for labs that have multiuser demands!

Each of the two bays of the GS2 Multi Block Thermal Cycler can be loaded with any of the ten different models of G-Storm Thermal blocks providing a staggering 45 different ways of customising the unit to your laboratories requirements. Each bay of the GS2 Multi Block Thermal Cycler can be operated totally independently to access and execute its  own Thermal cycling PCR protocol or the two bays can be operated together for larger scale experiments with throughputs of over 750 samples per hour.

Like its GS1 Thermal Cycler brother the  GS2 Multi Block Thermal Cycler blocks are under tetrad engine control ensuring accurate, uniform and reproducible execution of PCR protocols on the Multi Block Thermal Cycler regardless of sample loading and regardless of the external environment conditions. Protocols are reproduced consistently sample to sample and run to run. For peace of mind and quality control the performance of all runs on the GS2 Multi Block Thermal Cycler are stringently monitored by the three on-board processors and the execution of every temperature step is stored in a unique GLP file.  Complex thermal cycling protocols incorporating time increment and decrement, temperature increment and decrement, gradient, hot start, nested PCR and barcode tagging are easily created using an intuitive drag and drop programming style often copied by our competitors but never bettered.

Every GS2 Multi Block Thermal Cycler has an enormous memory with individual user directories, the capacity for over 10,000 PCR protocols and a massive 20cm (8 inch) colour touchscreen display. This makes the GS2Multi Block Thermal Cycler the ideal  core laboratory resource thermal cycler choice. The G-Storm GS2 Multi Block Thermal Cycler is perfect for the experienced scientist who demands the very highest specifications and features and its intuitive program wizard makes it also ideal for those who are new to molecular biology that require a thermal cycler that is easy to use and to program.

The GS2 Multi Block Thermal Cycler also benefits from class leading low power consumption and a remarkably small footprint per sample ratio, helping the environment, your lab budget and lab ergonomics. Furthermore it does this with no compromise achieving outstanding performance superior to its more power hungry and often larger competitors. Built to the highest specifications, the GS2 Multiblock Thermal Cycler offers everything you need from a thermal cycler.

FAST Blocks

Choose between standard and FAST Blocks:

• Ramp rate of up to 6°CS-1 with FAST Block option
• Increased productivity by faster protocols

G-Storm Ltd offer the choice of standard thermal blocks with a ramp rate of up to 3.5°CS-1 together with the  FAST Block (96 and 384) option with ramp rates of up to 6°CS-1.

Utilising a new electroplating process to reduce material thermal mass, the FAST Blocks are made from solid silver with a gold finish. The FAST Blocks have incredible thermal conductivity properties that
enable superb heating and cooling capability. These characteristics result in ramp rate of up to 6°CS-1, twice the speed of our standard anodised aluminium blocks. By increasing the speed of the thermal
block, protocols can be completed in less time, therefore enabling more samples to be run per day.

Fast Gradients

When optimising biological experiments, the same gradient functionality of the cyclers is available on the FAST Blocks, ensuring that whatever block option you choose, you can be sure to achieve the very best data from your biological material.
FAST Blocks are available in 96 well and 384 well options.
