DENSsolutions Ocean & Stream TEM Holders with Liquid Supply / Pumping Station Package

This equipment is sold on behalf of a client where it will be removed from a University Laboratory as it is surplus to requirements.

The package consists of two advanced in-situ transmission electron microscopy (TEM) holders and an associated liquid supply / pumping station. These systems are designed for highly controlled experimental workflows inside the TEM, enabling liquid-phase and temperature-controlled studies at the nanoscale.

The equipment is described as being in excellent condition, relatively new, and very lightly used. The items are not currently in use and are being sold to support the purchase of other laboratory equipment.

The package comprises the following:

DENSsolutions Ocean TEM Holder

• High-performance in-situ TEM holder for liquid-phase microscopy experiments.

DENSsolutions Stream TEM Holder

• In-situ TEM holder supporting heating, pumping and chip biasing functionality.

Supplied with the Stream holder:

• Laptop with control software for pumps, heating and chip biasing
• Impulse software
• Stream Temperature software

DENSsolutions Liquid Supply System / Pumping Station

• Liquid flow control and supply unit designed for use with the Ocean and Stream holder platforms.

FEI Tecnai G2 20 S-TWIN Transmission Electron Microscope

This item is sold on behalf of a client where it is surplus to requirements.

The microscope is fully functional and has been maintained under a Thermo Fisher service contract, with the most recent service completed in July 2025. It is currently fitted with a Tungsten filament but is also compatible with LaB6.

The system comprises the following:

• Tecnai G2 20 S-TWIN microscope column
• Megaview Soft Imaging System III camera
• One standard quick release specimen holder
• HT tank
• Turbo, rotary, and oil diffusion pumps
• Auxiliary equipment required for operation (with flexibility on chillers and compressor inclusion by discussion)

Additional details:

• Configured with enhancements for Lorentz microscopy, including a Lorentz lens upgrade for higher magnification imaging in low magnetic field conditions.
• Reversible polarity objective lens for in situ magnetising experiments.
• The standard objective lens is retained, allowing for full routine TEM functionality.
• A Gatan image filter is present but non-functional; the port blank is available and can be supplied in place of the filter.

Thermo Fisher Tecnai G2 Spirit Transmission Electron Microscope

This item is sold on behalf of a client where it is surplus to requirements.

This system is in good cosmetic condition and in complete working order.

It has been under a Thermo Fisher service contract since installation in January 2018, with annual preventative maintenance checks. The most recent service was carried out on 09/10/2023, and the chiller was repaired in January 2025. The system was taken out of use shortly after in preparation for installation of a new TEM.

Includes:

Cryobox (installed)

Single tilt sample holder

Fischione room temperature tomography holder (±70° tilt range, available for inclusion)

Air-cooled water chiller

Two computers: one for microscope operation and one networked support PC for remote engineer access

The system has been professionally decommissioned and prepared for transport. It is ready for reinstallation by a suitably qualified transmission electron microscope service provider.

A recommendation for a trusted recommissioning specialist can be provided upon request, with on-site setup available at an additional cost.

Combined system dimensions (W × L × H): approx. 300 × 250 × 220 cm

This item is non-returnable and non-refundable. The normal UniGreenScheme terms and conditions do not apply.
