Firstly, have a look at our spare parts. If this doesn't answer all your questions, then you can either e-mail us for advice, or send your order detailing the model of lamp you have, and describing the parts which need replacing. We can then try to identify the exact parts needed for you.
If you have an older model of lamp and require parts for a specific model (i.e. glass or frame), then the replacement glass you will require is;
Bialadin 315 = Vapalux M320 (part no. V805)
Bialaddin 300/300X = Vapalux M1B (part no. V60)
Please note that unfortunately we no longer have any remaining stock of glass for Bialaddin 310. This is a specially blown version, unlike existing models, which will no longer be available once existing stocks are exhausted.
However, we can supply glass for the existing models with an adapter which should ensure compatibility with older models.
