We offer extra protection for your valuable light-sensitive samples via amberization on Borosilicate NMR tubes only. The transmission rate between 300 to 800nm is lowered by several orders of magnitude after amberization. Just add "-AMB" to the product number of the tube you require, for example: 507-PP-7AMB, and submit your request at here.

Note: There is an additional charge for amberization. Please see table below; charges shown are per tube; 5 piece minimum

Tube OD                    Additional Price per Tube
3.0 to 8.0 mm:             $7.85 each tube
10.00 to 18.0 mm:        $9.00 each tube
20.0 to 30.0 mm:        $14.65 each tube

Amber staining is based on a high temperature ion-exchange process and has been adapted for Pyrex® or other borosilicate sample tubes. Quartz sample tubes cannot be amberized.
