When something breaks in the lab, replacement isn’t always the right call — and for complex or custom pieces, it’s rarely the smart one. At-Mar Glass has been handling laboratory glassware repair since 1982, working directly with pharmaceutical companies, university labs, and research teams who can’t afford to wait weeks or settle for subpar work. Every repair is done in-house at our Kennett Square, PA, facility by experienced glassblowers who’ve seen just about everything.
Replacement sounds simple until you’re looking at lead times, custom specs, or a piece that’s no longer in production. For most labs, repair is the faster, smarter option — and often the only one that makes sense.
Custom and specialty glassware isn’t cheap, and broken lab glassware doesn’t have to mean a full replacement order. Repair costs a fraction of what new pieces run, and for high-value items — distillation setups, custom condensers, specialized reaction vessels — the savings add up fast. Your budget has better places to go.
Ordering new glassware means waiting on production schedules, shipping delays, and back-order surprises. Lab glass repair with At-Mar can turn around in as little as a weekend depending on scope — which means less downtime, fewer disruptions, and your work back on track before a new piece would’ve even shipped.
Some pieces can’t just be reordered. Custom configurations, discontinued items, and legacy lab equipment repair needs require a skilled hand and a real understanding of how the glassware functions. A quality repair doesn’t just fix the damage — it restores full functionality and extends the working life of equipment worth keeping.

If it’s made of glass and used in a lab, there’s a good chance we can fix it. Here’s a breakdown of the most common repair work we handle.
Worn, chipped, or cracked joints are one of the most common reasons glassware gets pulled from service. Glass joint repair covers standard taper joints, custom ground fittings, and compromised seals across all types of lab apparatus. We restore the fit and integrity so connections hold under pressure and thermal stress without issue.
Cracks, breaks, and structural damage don’t always mean a piece is done. We work with borosilicate glass repair across a wide range of apparatus, and can handle glassware modification at the same time — adding ports, changing configurations, or adjusting dimensions while the piece is already in the shop.
Not every repair is straightforward, and that’s fine by us. Scientific glass blowing repair for complex or one-of-a-kind pieces requires real craft, not just technical skill. We handle intricate multi-component assemblies, custom reaction setups, and specialty research apparatus that most shops won’t touch.
Getting your glassware repaired with At-Mar is straightforward. Here’s what to expect from start to finish.
Before sending anything in for scientific glassware repair, make sure all pieces are thoroughly cleaned and free of residual chemicals or hazardous materials. Pack them securely to prevent additional damage in transit. We recommend using the original packaging when available, and documenting the damage before you ship.
Once your glassware arrives, we inspect it and assess the full scope of work. You’ll receive a clear estimate before any repair begins. If we spot anything beyond the original damage, we’ll flag it. No surprises, no work started without your approval.
With approval in hand, our glassblowers get to work. Our glassware repair service is handled entirely in-house, so there’s no hand-off, no waiting on a third party, and no guessing about who actually touched your equipment. Once complete, everything is inspected and carefully packaged for return.
There’s no shortage of options when it comes to lab glass repair. Here’s what makes At-Mar the shop labs keep coming back to.
Every job stays under one roof. Our facility in Kennett Square, PA handles custom glassware repair with equipment built for serious work, including ovens that reach 600°C and above. No outsourcing, no subcontractors, no uncertainty about how your pieces are being handled or by whom.
At-Mar has been in business since 1982, and that history shows in the work. Lab glassware restoration at this level requires more than technical ability. It requires judgment, pattern recognition, and the kind of hands-on experience that only comes from decades at the bench working through problems other shops send back.
Location isn’t a barrier. We work with labs and research teams across the country, and shipping is straightforward. Orders over $500 ship free. Pack your pieces well, send them in, and we’ll get them back to you in good shape.
Common questions from labs and research teams before sending in their first order.
Cost depends on the scope and complexity of the work. The best way to fix broken glassware without overpaying is to send it in for an assessment first. We provide a clear estimate before any work begins, and our pricing is straightforward with no hidden fees or surprises.
Most borosilicate lab glassware is repairable, including flasks, condensers, distillation setups, custom reaction vessels, and specialty research apparatus. If you’re unsure whether a piece is worth repairing, send it in anyway. We’ll assess it honestly and let you know what’s possible.
Turnaround depends on the complexity of the job and current volume. Straightforward repairs can be completed in a weekend. More involved work takes longer. We’ll give you a realistic timeframe during the estimate phase so you can plan accordingly.
Yes, without exception. All pieces must be fully cleaned and free of chemical residue or hazardous materials before shipping. This protects our team and ensures we can handle your glassware immediately upon arrival without delays for decontamination or additional processing.
Absolutely. If your piece is already coming in, it’s a good opportunity to make modifications at the same time. Adding ports, adjusting dimensions, or changing configurations can often be handled alongside the primary repair with minimal additional turnaround time.
Reach out before you ship. Call us or fill out our contact form to describe what you’re working with, and we’ll get back to you with a clear, no-obligation estimate. Orders over $500 ship free, so if you’ve got multiple pieces that need attention, it’s worth bundling them into a single order.
