Grid Boxes

Grid Boxes

Hybrid Grid Box

Hybrid Grid Box

Hybrid Grid Box's patented design has separate pockets for unclipped grids and autogrids, securely cradling samples while allowing for unmatched ease in placement and removal. Makes for easier workflow with fewer grid boxes needed and easier traceability of samples from vitrification through imaging.

Bulk Storage Grid Box

Bulk Box with 12 Autogrids

The Bulk Storage Grid Box's patented design stores 12 autogrids optimally, and can also hold 12 unclipped grids comfortably in the same slots. Storage for an entire cassette of grids from vitrification through to data acquisition. Optimal storage density and sample traceability in one grid box.

Metal Universal HPF & Grid Box

Metal Universal HPF & Grids

The Metal Universal HPF & Grid Box holds HPF hats, bare grids and autogrids all in 1 pocket. The first storage box to hold 3mm HPF hats. The flat sides make for easy screwing in and out of a lid in HPF workstations without cut-outs to hold grid boxes. Furthermore, the anodized aluminum material is robust and can be autoclaved.

Low Profile Lid with Tweezers.jpg

Low Profile Lid

The Low Profile Lid has a thickness that is small enough that 2 grid boxes can be stacked in 1 pocket of a cryoEM storage puck. Furthermore, the anodized aluminum has lower susceptibility to static electricity than plastic lids.




Cryo-Tweezers Clamp

The Cryo-Tweezers have modified reverse-action tweezers so that you don't have to fight with the Vitrobot tweezers and the black clip to hold grids.  Plus the spring-loaded clamp makes placing and removing the tweezers from the plunge arm much smoother, making your life easier and reducing the number of wasted grids.



The Igloo interfaces with the Vitrobot vitrification dewar to reduce cryoEM sample contamination through multiple features, and creates an overall easier sample preparation process, leading to improved sample preparation efficiency. 

Vitrobot Foam Dewar & Metal Parts

Vitrification Dewar incl. Metal Parts

The foam Vitrification Dewar and Metal Parts are compatible with the Vitrobot, and all of the parts are interchangeable with FEI versions of the foam dewar and metal parts. Furthermore, the dewar design provides an improved interface with the Igloo, creating a better seal to contain cold nitrogen gas.

Ethane Condenser

Quick Lid


Easy to place condenser cap interfaces securely with the Vitrobot spider enabling "one-handed" ethane condensing, where the user can focus solely on controlling the ethane flow rate and the level of liquid ethane.


Easy to place lid can be quickly placed onto grid boxes during vitrification sessions to protect already frozen grids while they wait for the session to be complete. The weight of the stainless steel part keeps it securely in place.



Clipping Station

Our Clipping Station is the first station to provide a high quality foam dewar that integrates storage puck access, clipping and cassette loading in one system. Furthermore, a new clipping design utilizing a downward press with tweezers rather than twisting of Thermo's brass cylinder is much more natural, and along with a usable, efficient lid, provides a top-of-class clipping system.

Autogrid Rings

Autogrid Ring

NanoSoft's Autogrid Rings are a premium quality, less variable version of autogrid rings for use in Thermo Fisher cryoEM autoloader systems, at half the price. Our rings are manufactured with cutting edge technology, enabling such high quality.



NanoSoft's C-clips function the same as the TFS version, and are compatible with both NanoSoft and TFS autogrid rings.

Rev. Action Autogrid Tweezers

Clipping Tool

Clipping Tool
Reverse Action Autogrid Tweezers.jpg

The Clipping Tool is compatible with Thermo Fisher's clipping station. Its compact design means when placed into the clipping station, it stays deep enough to remain free from ice contamination condensing onto the Clipping Tool. It is easy to move the Clipping Tool and eject the c-clip with a pair of tweezers.

A reverse-action version of our Autogrid Tweezers, with the same notched tips but with the convenience and security of reverse-action tweezers.

Autogrid Tweezers

Autogrid tweezers for manipulation of autogrid cartridges, with same dimensions as the Thermo Fisher version, but with a significantly lower price.

Autogrid Inspection Tool


Tool enables a final check of clipping quality before loading autogrids into the autoloader cassette, potentially saving weeks in TEM down time, which is likely in the case of loading a poorly clipped grid that comes unclipped in the autoloader or column.

C-Clip Bottoming Tool

C-Clip Bottoming Tool

The C-Clip Bottoming Tool provides a more efficient and convenient way to push C-Clips to the tip of the barrel of your clipping tools. It works with NanoSoft or Thermo Fisher clipping tools. It ensures your tool stays straight so that your C-Clip is positioned appropriately and can't fly out of the barrel.

General Cryo & Sample Preparation 

General Sample Prep

Spearlab Tall Dewar

Spearlab Standard Vessel

Pin Lid Tool Manipulator


Spearlab Tall Dewar is a foam vessel capable of holding LN2 and is perfectly sized to slip cryoEM puck canes into to place into/remove from transport/storage dewars at cryo temperature during sample retrieval


Spearlab Standard Vessel is a foam container capable of holding LN2 and the perfect size for any grid box or grid workflow steps/processing necessary

Pin Lid Manipulator Tool

The Pin Lid Manipulator Tool is designed to have 2 slots in the tip so that the tip flexes when the user pushes it down onto a pin lid. This results in a tighter grip on the pin lid, without needing to press down so hard. Furthermore, the thoughtful design results in the tip not unscrewing when screwing pin lids into grid boxes - and not freezing your fingers.
