Tutorial Coming Soon Safety Equipment Locations


Vacuum Chambers are used for degassing resins and epoxies, for mold-making and casting operations, for electronics potting, and more. This Corning pyrex 5.8 Liter Large Top Desiccator is connected to a 3/4 HP oil-less graphite rotary vane vacuum pump made by Gast. Because degassing can outgass solvents and other chemicals, read below to make sure your project can be done safely in the available facilities.

How to Start

  • Send an email to with the complete procedure you would like to perform in the vacuum chamber. Include the following information:
    • For any materials (resins, epoxies, etc) you will be using, attach the MSDS information.
    • Specify whether you will be mixing by volume or mixing by weight.
    • If you are mixing by weight, what kind of scale do you need and where will you obtain one? Think[box] has a bench scale ( model 1863T61) that can measure up to 2000 grams with an accuracy of +/- 1 gram. If that is not sufficient for your project, specify where you will find a suitable scale.
    • Mixing cups are not available at think[box]. If you need mixing cups, specify where you will be obtaining them. Consider using a mixing cup with graduated markings (example), especially if you are mixing by volume.
    • Specify what PPE (personal protective equipment) you will be wearing, and when you will put it on. Think[box] has safety goggles, lab coats, and nitrile gloves available. If you need additional PPE, specify where you will obtain it.
    • Specify how you will clean up any spilled material. For most epoxies and mold-making materials, you may use paper towels to thoroughly clean the vacuum chamber, the workbench, or any other surface that comes in contact with your materials. We ask that you help us keep the facility clean and remove every single drop of spilled material, no matter how small.
    • Specify what you will do in the event that your skin or eyes come in contact with the materials you are using. Use this map to find the eyewash station in think[box] and the safety shower in the hallway, and mention the locations in your procedure if they are needed.
  • After you email your procedure and MSDS information, you must now wait for a response. A staff member will review your procedure and respond, usually within 3 working days. If you are approved, you may come to the lab and perform your procedure. If you are not approved, the staff member will tell you why, and you may then try to find a suitable laboratory that will support your procedure.
