We stock Lab Glassware & Supplies as part of the Field Science & Education group because the same crews keep asking for it alongside specimen and sampling kits, water and soil test kits, classroom activity sets, reference books and maps. Sizes, thread pitches and pack quantities are listed per SKU so a repeat order lands on the same part you bought last time.nnTypical orders from this category mix specimen and sampling kits, water and soil test kits, classroom activity sets, reference books and maps. Where a part is available in several sizes or finishes, each one is a separate SKU with its own price and stock count so you are not guessing what arrives in the box.nnFree ground shipping applies to US orders over $39; everything else is a flat rate calculated at checkout. Most orders leave the dock within 1–2 business days. We take returns for 30 days on unused, resalable goods — sealed adhesives, opened abrasives and cut-to-length items are excluded. Email [email protected] with your order number if a part does not match the listing and we will sort out the correct one.
