Digital High Vacuum Accessories - Bell Jars & Evaporation Equipment

A shield greatly reduces deposits of evaporated metals on the electrodes and bell jar, yet allows clear observation of the amount on the specimen. Special features of each unit are:

• Two side arms which fit filament posts, each supporting a chrome-plated disc. 
• An annealed Pyrex tube which slides over the discs and is held securely in place by a coiled spring. 
• A precisely sized slot in the tube, which aligns accurately with a hole in the metal shield held in place beneath the slot, allowing controlled passage of evaporated metal to specimens. 
• Pyrex tube and metal shield can be rotated, permitting coating or shadowing from any angle. 
• Pyrex tubing will not crack from heat generated during evaporation. 

Complete instructions included with each unit.

The Replacement Tube is Annealed Pyrex. Extra tubes are helpful, since one can be in use while others are being cleaned. All edges are fire polished.

We have decided to discontinue the manufacture of all Ladd Vacuum Evaporators. However, we will continue to sell most parts and accessories for them. Please call us at (802) 658-4961 if you require a part or if you have any questions. 

Key advantages of a turbo pump over a diffusion pump:
1.  Quicker pump down. From a cold start to high vacuum
      in less than 3 minutes.
2.  Cleaner system - No oil vapors.
3.  Better, faster vacuum.
4.  Air cooled. Water is not required for cooling a turbo pump.

Modular unit fits any vacuum evaporator. Easily installed or removed in seconds. No time lost assembling or disassembling filament posts, arms or tungsten baskets. Adjustable height allows basket to be positioned at optimum level for evaporation of metals. Two insulated posts firmly mounted in heavy base. Moveable arms extending from each post have clamps for basket leads, with thumb screws to hold the tungsten basket securely in position. Please specify evaporator model used when ordering. Includes package of Tungsten Baskets. Two sets of posts which will hold two baskets or crucibles to allow you to do more without breaking vacuum. Same as Dual Source Tungsten Basket / Crucible Holder, but with two shields to avoid cross contamination.
