EMS25 TEM Grid Storage Boxarrow11EMS25 TEM Grid Storage Box

The EMS25 is a small capacity grid storage box, designed as a low alternative to larger grid boxes where extra storage capacity is not required.

The box has a sliding cover, allowing access to 5 slots at a time.

Each diamond shaped hole is capable of storing a 3.05 mm or 2.3 mm diameter grid. Storage referencing is managed via recessed alpha numeric indexing on the sides of the box.

The box contains two side features, allowing for easier handling during specimen removal, as well as a matte strip for extra notation.

The EMS25 is also available with a unique number printed in blue on the face, code EMS25BN; batches with sequential numbers are available. Both boxes come with a durable 25 column card for record keeping.

Our grid boxes are intended for use in both routine grid handling and for long term grid storage. Their compact flat shape and low cost make them well suited for the transportation of coated grid products and for the long term storage of catalogued specimens.

TEM-Specimen Grid Boxarrow11TEM-Specimen Grid Box – SB50

This newly designed TEM grid storage box, for routine handling and long term storage of 50 standard size TEM grids. This new ergonomic design incorporates several features that overcome the disadvantages associated with storage boxes of the more conventional “sliding cover” design. This new box has a unique number on the face and on one end.


Size75 mm (L) x 65 mm (W) x 6.5 mm (D)
Weight22 grams
Materials: Base:ABS-PHAT (Acrylonitrile Butadiene Styrene + Anti-Static Additive)
CoverCAB (Cellulose Acetal Butyrate)


  • The blue arrow at the 12:00 o’clock position indicates the park position for the cover when not it is not in use. This is a firm grip “click” position and it cannot be moved accidentally thus preventing spillage
  • The clear cover can be rotated smoothly through 360 degrees once the slight initial resistance of the park position has been overcome exposing a maximum of 2 or 3 diamond shaped slots at any one time
  • The 50 diamond shaped slots have an alphanumeric referencing system. Each box is supplied with an index record card for additional information
  • The material the bases are made from have been chosen due to their anti-static properties. The clear cover has self-lubricating properties, which reduces friction, enabling the cover to move freely while remaining in close contact with the face of the base
  • The storage boxes are designed to be stacked, the base locating precisely over the face of another box

EMS Domino Rackarrow11EMS Domino Rack

The EMS Domino rack is “U” shaped and made from an aircraft alloy sheet stock with serial perforations; thermally bonded spaceage copolymer; 5 mm diameter holes, 28 holes per rack. The formvar film cast on the rack will stretch across a series of smooth edged holes forming a flat, wrinkle free film that is ready for grid mounting. The Domino Rack allows the sections within the slot to dry flat and wrinkle free; it reduces the film and section contamination to negligible levels.

arrow11Grid-Stick Kit

A helpful device for multi grid staining. If instructions are followed carefully you can say good-bye to precipitate and dirt. The Grid Stick is made from a thin, but rigid alloy that does not react with commonly used organic solvents or stains. The stick itself measures 4 mm wide, 75 mm long and has a slot along its center with small undercut notches on one side to make grid removal simple. A small area on the top of each stick is reserved for identification.

The Grid Stick is coated with a specially-formulated pressure- sensitive adhesive. This adhesive is resistant to solvents used in conventional staining methods (e.g., water, alcohol, ethanol) and aggressively holds the grids in place during staining, emulsion coating, carbon coating, shadow casting, serial section collection, etc., yet will not remain on the grid once it is removed from the stick. During staining the grids are held in the same plane as the solution flow, minimizing the risk of breaking the formvar film and, or collecting surface debris.

Grids may be stored, handled, and examined with minimal effort. For example, if your grids are on SynapTek Grid Sticks you can simply place the stick on the stage of a phase microscope, identify the material (you will see outlines of large cells), and determine its condition (i.e., holes in material, dirt on grids) in only a few seconds without disturbing a single grid. In short, you will find that the SynapTek Grid Stick is simple, easy to use, and most importantly, highly reliable.

SynapTek Grid-Stick consists of

  • 5 coated Grid Sticks
  • 10 Staining Pipettes (modified)
  • 2 flow-limiting Plugs and Bulbs
  • Instructions

Replacement Components

arrow11Grid Coating Pen For TEM; Coat Quick “G”

The Coat-Quick “G” pen improves the adherence of tissue sections onto the grids. With a touch of the pen to the grid, a thin layer of coating is applied to the grid. Drying takes place in approximately 1-2 minutes at room temperature. After it has dried the grid is ready for tissue mounting. The pen is also used in pretreating grids prior to mounting supporting films such as formvar and carbon; it minimizes dislodging, widening, or breaking of the support film.

The EMS Staining Plateemsexclu.gif (210 bytes)arrow11The EMS Staining Plate

The EMS Staining plate for Electron Microscopy was developed by Dr. Miguel Berrios, at SUNY at Stony Brook, Dept of Pharmacological Sciences, School of Medicine, New York.

The chemical etching process, antibody incubations and final staining with heavy metal salts of each grid is performed in the small cone-shaped wells on the EMS staining plate.

The EMS Staining Plate for electron microscopy post-embedding staining and immunohistochemistry offers several advantages over all other commercially available staining devices. The base plate is a solid piece of chemical-resistant silicone 127.5 mm long, 85.5 mm wide, 11.5 mm thick with 96 cone-shaped wells organized (like the microtitration plate) in parallel rows of eight, using the lid of a 96-well Falcon 3072 Microtest™ III Plate as a cover. The base has two notches to serve for orientation and a 1.5 mm x 4.4 mm deep lip where the cover rests. Each well is an inverted cone 7 mm in diameter and 2 mm deep. Grids either float or rest at the bottom of each well. The wells allow incubation of a grid in 12-60 microliters of solution without reagent loss due to adsorption or cross contamination, even when the plate is tilted up at 70°. Due to the shape of the well, the flat surface of the grids never come into contact with the walls of the well, both facilitating sample staining and grid recovery.

Plates made from silicone offer two advantages

  • Resistant to all chemicals and solvents
  • During manipulation of the grids in the well there is no risk of damaging the fine points of the tweezers
