[Nhcoll-l] Seeking Quality Freezer Bags

[Rivin, Meredith]

I’m not sure how the prices compare to Uline, but I like GT Bags https://urldefense.proofpoint.com/v2/url?u=http-3A__www.gtbag.com_&d=AwIFEA&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=CLFZJ3fvGSmDp7xK1dNZfh6uGV_h-8NVlo3fXNoRNzI&m=o82qY8xXsBxtN4-iBm8ed3uAsITfMQeJJ1eB1ksk9MA&s=FjIUSFlZvc4lRn6SIqrc-QRLHGddsXZ59pua1Kt771g&e= .  You can choose 2, 4, or 6 mil in a variety of sizes.

Hi Derek

It is best to avoid bags designed for food storage as these contain, at least in the US, an FDA mandated additive (butylatedhydroxy toluene (BHT)) that will leach into objects/specimens over time and will oxidze to colored compounds.

We buy 3 mil or thicker zip top polyethylene bags designed for small parts from: https://urldefense.proofpoint.com/v2/url?u=http-3A__www.uline.com_Product_AdvSearchResult.aspx-3FKeywordTyped-3D4-2520mil-2520poly-26keywords-3D4-2520Mil-2520Poly-2520Bags-26SubGroups-3D114-26view-3DALL-26TrackSearch-3DN&d=AwIFEA&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=CLFZJ3fvGSmDp7xK1dNZfh6uGV_h-8NVlo3fXNoRNzI&m=o82qY8xXsBxtN4-iBm8ed3uAsITfMQeJJ1eB1ksk9MA&s=w7_B9EhWrsjjwAEjmmJWqP_Pl1wN43tlqHOR7HDILfs&e= <https://urldefense.proofpoint.com/v2/url?u=http-3A__www.uline.com_Product_AdvSearchResult.aspx-3FKeywordTyped-3D4-2520mil-2520poly-26keywords-3D4-2520Mil-2520Poly-2520Bags-26SubGroups-3D114-26view-3DALL-26TrackSearch-3DN&d=AwMGaQ&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=CLFZJ3fvGSmDp7xK1dNZfh6uGV_h-8NVlo3fXNoRNzI&m=LxB2ckeqqTpeQBFMskMpvGNjunJowa-C20eY9Ow7P2Y&s=8MMYN7hfmPB0oXgKl5v_sh_PSzTmqQgFChgLdpoFm9M&e=>

Hello, all! My lab is in need of suggestions for quality freezer bags. We have been using Ziplocs and such for a while, but they tend to break down over time to a degree and we want better quality bags. We're keeping vials in the bags inside regular freezers, although occasionally they'll also go into a -80 degrees C freezer as well.

I welcome any assistance that people can provide.

Thanks!

Regards,
