Standard Rotary Shadower - A necessity for shadowing rough or "hollow" replicas. Rotation of a replica at 10 rpm in the horizontal plane during shadowing eliminates loss of detail. The rotary shadower has a 10 rpm motor which rotates an aluminum platform. Two spring clips on the platform securely hold a 3" x 1" glass slide supporting specimens to be rotated. A clip on top of the motor housing holds a 2" x 2" replaceable glass slide which protects the glass bead insulators on the 8" leads from deposits of evaporated metal and carbon. A solid aluminum base gives stability to the unit. Please specify type of vacuum evaporator used when ordering.

60840

Variable Speed Rotary Coater (Shadower) with Platform  -   This variable speed unit, which rotates in the horizontal plane only, is excellent for coating SEM specimens where multiple evaporation sources are used and uniformity of coating is not critical. Equipped with the same motor and motor housing as the tilting model, it requires the same D.C. power supply, which gives the platform a continuously variable speed from 3 to 120 rpm. This unit may also be used as a variable speed rotary shadower in transmission electron microscopy, if only one evaporation source is used. Unit sold without power supply.

60825

Tilting Variable Speed Rotary Coater with Platform  - Compact coater, specifically designed to prepare scanning electron microscopy specimens; features simplicity of design and ease of operation. It can be installed in (and removed from) any vacuum evaporator in just seconds. The tilting motion through 90^o, with associated processing, plus use of a moving top shield and a fixed vertical shield, ensures uniform coating of the specimen being rotated. Without these shields, uniform coating is impossible to obtain, a fact confirmed by densitometer readings of coated specimens examined with TEM. Such uniformity of coating thickness is essential for accurate interpretation of resulting micrographs. The motor is enclosed in a vacuum-tight, lightweight metal housing, thus eliminating pump-down problems associated with D.C. motors in vacuum. Operation requires a 0-15 volt, D.C. power supply outside the vacuum, which gives the platform a continuously variable speed from 10 to 120 rpm. Instructions included. Unit sold without power supply.
