Grid Preparation Supplies


Film Casting Device
An all glass apparatus. It casts uniformly thin films of parlodion, formvar, or butvar directly onto 1x3 microscope slides. The film casting solution can be used repeatedly. A built-in fine-pressure-release valve helps control the speed of drainage. The thickness of the film is controlled by the concentration of the film solution and the rate of the drainage. The unit requires 100mls of film casting solution to start.
The unit comes complete with:
- 500 ml capacity flask with built-in valves; Air-in and Air-out.
- Film casting Cylinder with Cover.
- 75 cc Atomizer.

Grid-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 4mm wide, 75mm 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

Grid 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.

Multipurpose Electron Microscope Specimen Box -
MEM Grid Box
A newly designed Grid Box with safety, ease and convenience in mind – This multipurpose electron microscope specimen grid box is one of the most desirable boxes on the market
Advantages:
- Eliminates the chances of tweezer insertion damaging the grids – The ‘tweezers slot’ and ‘grid slot’ are in a separate location. The tweezers are only able to grip the edge of the grid enabling it to be picked up.
- Grids stored no longer jump out of the box while you remove the cover –
Between the body of the box and the sliding lid, there is a separate plastic cover, which allows for only four slots being exposed at a time.
- The Grid Record Card is stored safely by insertion along on the reverse side of the box.
- MEM-96 – will able to store up to 96 grids
- MEM-32 – will able to store up to 32 grids with 8 Blocks
- Measures: 81mm L x 54mm W x 6mm Thick.

TEM-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.
Specifications:
| Size | 75mm (L) x 65mm(W) x 6.5mm(D) |
| Weight | 22 grams |
| Materials: Base: | ABS-PHAT (Acrylonitrile Butadiene Styrene + Anti-Static Additive) |
| Cover | .CAB (Cellulose Acetal Butyrate) |
Features:
- 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 Rack
The EMS Domino rack is "U" shaped and made from an aircraft alloy sheet stock with serial perforations; thermally bonded spaceage copolymer; 5mm 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.

The
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 127.5mm long, 85.5mm wide, 11.5mm 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 1.5mm X 4.4mm deep lip where the cover rests. Each well is an inverted cone 7mm in diameter and 2mm 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.
