[Nhcoll-l] borosilicate glass

[Gartner, Heidi RBCM:EX]

Hello All!

I am looking to source some storage jars for our fluid preserved invertebrate collection at the RBCM.  I understand that borosilicate glass is optimal for use in museum work as it can withstand greater physical, chemical, and temperature stress.  However, I am having difficulties sourcing borosilicate jars in the sizes I need.  It seems most jars sold are either flint or soda-lime glass.  So I am hoping the group can help answer the following questions:

*         Do you have a good supplier in North America for a wide range of borosilicate jar sizes?

*         What are the long term effects of using flint or soda-lime glass?  (e.g. Greater risk to general handling? Any chemical reactions that may affect DNA work?)

Thank you for your time,
