IISER-K/PurEnq/594/P/DCS/20-21

A. ATOMIC FORCE MICROSCOPE

Rate should quoted for the Items serial no. 1 to 4.9 as per the specification given in Annexure VI of the Tender Notice

System must include an accessory that enables application of a variable high voltage (+/- 150 V) bias between the tip and sample. Voltage must be software controlled and capable of high frequency (>100kHz) operation. Accessory must include features and training to help ensure safe operation

A temperature control stage/s for variable temperature studies from -20°C or less to 120°C or more should be provided optionally. This should be compatible with the system and have the capability to be used in special gaseous environment. This stage should support samples up to 8 mm in diameter. The kit to include all necessary accessories for sealed operation. This should include special cantilever holder if required for refined results.

ENVIRONMENTAL CONTROLLER. Stand-alone temperature controller with bi-directional current supply for use with AFM heating and cooling sample stages. Should have built-in microcontroller to regulate closed loop temperature feedback independent from the AFM controller or PC computer. It should be Fully operated through the graphical interface of the software. Temperature controller along with resistive heating elements and thermistors provide should provide temperature control.

Force-distance curve mapping technique that operates at up to 300 Hz pixel rate or more and captures every force curve in the image, with no missing curves or hidden data manipulation. Should allow real-time and offline analysis models that can be applied to calculate modulus, adhesion and other properties. Models are fully accessible by users with a wide range from 10 kPa to 100 GPa or more.

System must include or optionally support (specify which) an imaging mode that is capable of generating quantitative nanoscale maps of storage and loss modulus, and loss tangent (loss modulus divided by storage modulus), at high pixel resolution (at least 1024x1024 pixels). Data capture must occur during normal AC mode imaging of topography at normal scan rates (<20 minutes per scan). Proposals for techniques that map storage modulus only are insufficient and will be rejected

Optional: 1 year extended warranty

Optional: 2 year extended warranty

B. MICROSCOPE (CONFOCAL IMAGING UNIT)

Rate should quoted for the Items serial no. 7 to 11 as per the specification given in Annexure VI of the Tender Notice

COMPUTER WORKSTATION. System must be controlled with computer control unit having the latest configuration (processor of 3.5 GHz or better, with at least 16 GB RAM, 1 TB SATA hard disc drive, Windows 10 Professional (64 bit) operating system, USB 3.0/2.0, Firewire, NVIDIA 1GB high performance GPU. One LED Monitor at least 30” LED monitor

BRANDED ACTIVE ANTIVIBRATION TABLE. A suitable branded anti-vibration table with air suspension support should be provided.

Motorized Encoded Scanning stage instead of manual XY stage with all accessories and software control module (Additional Price)

sCMOS camera with 100 fps, 82% or more QE with full well capacity of 30,000 e and dynamic range of 37,000. instead of camera quoted in the main offer (Additional Price)
