Mercox II Dye

Comes in Red and Blue Because these dyes are very potent, additional dye is usually not necessary for Red and Blue Mercox. Use only if you wish to enhance the color and then use judiciously. The dyes are to be used principally to colorize the Clear Mercox.

Starting at: $29.95

21235 - Methyl-Butyl Methacrylate Embedding Kit

80:20 mixture of butyl and methyl methacrylates provides a plastic with excellent cutting properties. The hardness of the plastic can be varied by altering the relative proportions of the two components. The medium can be cured chemically or by ultraviolet radiation. We particularly recommend this embedding medium where the medium must be removed prior to staining. This acrylic copolymer is easily removed from the cut section by treatment with acetone or xylene.

$189.95

70400 - Paraplast - 1 kg

Mixture of purified paraffin and carefully sized plastic polymers formulated to provide specimen support for serial sectioning down to 4 µm with minimal cell shrinkage and distortion. Supplied in pellet form.

$20.95

21240 - Quetol 651 Embedding Kit

Low viscosity embedding medium. Penetrates specimens readily and completely. The epoxy component is completely miscible with water. Polymerizes in about 24 hours at 60º C.

$139.95

21230 - Spurr Embedding Kit

Low viscosity epoxy embedding medium. Particularly useful with hard tissue. Excellent block quality. Sections stable under the electron beam. Please Note: This kit no longer contains VCD (ERL 4206). Instead, ERL 4221 has been substituted.

$81.95

21220 - Ultra-Low Viscosity Embedding Kit

Similar to Spurr embedding kit except lower in viscosity. Exceptional penetration for an epoxy resin mixture. Useful for embedding plant and bone tissues. This kit no longer contains VCD (ERL 4206). Instead, ERL 4221 has been substituted.

$83.95

55140 - Durcupan ACM Embedding Kit

For water-insoluble epoxy embedding.
