Laboratory Glass Repair

Think of it as high-tech recycling. We can and do repair all sorts of laboratory glassware; any items much more complex than beakers and testtubes are fair game. Individually, each piece of broken lab glass is a unique situation although the fix is often straight forward: reattach or replace a new joint, thread, or stopcock, seal a star crack, fill chips in a flange, etc. Emailing a photo can be very informative in terms of a rough estimate. We won't charge more than half the value of the new item without consulting you. If the glassware is broken in a "working" area, that is, the shell of a stopcock, the ground part of a joint, a flange, etc., those parts can be replaced as good as new. We do mean as good as new - repairs are carried out in the same manner as manufacture of new lab glassware.

We try to accommodate your needs for rapid service. When your operation is down due to the lack of one piece of lab glassware, you need it now. We maintain a stock of most sizes of tubing and components, so we usually have the necessary materials in hand. We understand your need for quick turn-around and will make every effort to meet that need when possible. We do charge to expedite orders.

We ask that lab glassware needing repair be clean, and we must know what any contamination might be. In the course of repair, the glassblower frequently needs to connect a blowtube to the glass to blow and/or suck to work a seal. A specific problem is silicone greases and heating oils, commonly used on manifold stopcocks and cooling coils in condensers; citrus-based solvents work well for this cleaning. Burning silicone products produces toxic fumes and will create health hazards for the glassblowers and damage our ovens, not to mention your glassware! Any time we must spend cleaning will be charged at double our normal shop rate; we are expensive dish washers. A rule of thumb - if you would be willing to drink water from it, it's clean enough.

That said, we can burn out organics by running the glassware through an annealing cycle; organic compounds combust readily at a thousand degrees Fahrenheit . We will still need to know what the material is before agreeing to do this

If you ship us glassware for repair, please pack it carefully. This generally means plenty of packing between items; we like bubblepack around the glass, and starch based foam pellets (Eco-Foam or Renature) to fill. Leave plenty of room between the items and the walls of the box. Best is to overfill the box with pellets, then snug them down when you tape the box closed; this locks the glassware in place within the box. Remember, the shippers are specifically allowed to drop any box four feet, and don't think they won't. We also like it if you can put tape over the nasty sharp edges, so we don't shred our fingers unwrapping.
