Nasco® 　　Transparent sample bags are sterile, disposable, and economical. They are constructed of durable polyethylene and provide safe, spill-free use for liquid, semisolid, and solid samples. To use, tear bag on perforation and pull tabs to open. Fill bag, pull wire ends, whirl shut, and lock. 　　Write on clear bags with a felt-tip marker, or choose bags with a white, write-on strip and use an ordinary ballpoint pen or pencil. 　　Stand-up bags feature a gusset on the bottom that flattens out when the sample is placed inside, allowing the bag to stand up by itself without the need for racks or special holders. 　　Bags with White Write-on Strip 　　Capacity Thickness W x L Supplier No. VWR Catalog Number Unit 　　59 mL (2oz.) 2.25 mil 7.6 x 12.7 cm (3 x 5") B01064WA 11216-772 Case of 10000 　　Pack of 500 　　118 mL (4oz.) 2.25 mil 7.6 x 18.4 cm (3 x 71/4") B01062WA 11216-774 Case of 10000 　　Pack of 500 　　29 mL (1oz.) 2.25 mil 6.4 x 12.7 cm (21/2 x 5") B01067WA 11216-770 Case of 10000 　　Pack of 500 　　710 mL (24oz.) 3.0 mil 15.2 x 22.9 cm (6 x 9") B01297WA 11216-500 Case of 3000 　　Pack of 500 　　5441 mL (184 oz.) 4 mil 38.1 x 50.8 cm (15 x 20") B01447WA 89130-776 Case of 200 　　Pack of 100 　　532 mL (18oz.) 2.25 mil 11.4 x 22.9 cm (41/2 x 9") B01065WA 11216-776 Case of 6000 　　Pack of 500 　　Stand-Up Bags with White Write-on Strip 　　Capacity Thickness W x L Supplier No. VWR Catalog Number Unit 　　710 mL (24oz.) 3.0 mil 15.2 x 22.9 cm (6 x 9") B01401WA 11216-920 Pack of 500 　　118 mL (4oz.) 2.5 mil 7.6 x 18.4 cm (3 x 71/4") B01364WA 13500-390 Pack of 500 　　532 mL (18oz.) 3.0 mil 11.4 x 22.9 cm (41/2 x 9") B01365WA 13500-392 Pack of 500 　　Standard Bags 　　Capacity Thickness W x L Supplier No. VWR Catalog Number Unit 　　798 mL (27oz.) 3.0 mil 12.7 x 30.5 cm (5 x 12") B00990WA 11216-089 Case of 3000 　　Pack of 500 　　207 mL (7oz.) 3.0 mil 9.5 x 17.8 cm (33/4 x 7") B00992WA 66175-612 Pack of 500 　　710 mL (24oz.) 3.0 mil 15.2 x 22.9 cm (6 x 9") B01020WA 11216-409 Case of 3000 　　Pack of 500 　　532 mL (18oz.) 2.5 mil 11.4 x 22.9 cm (41/2 x 9") B00736WA 11216-056 Case of 6000 　　Pack of 500 　　59 mL (2oz.) 2.25 mil 7.6 x 12.7 cm (3 x 5") B01009WA 11216-373 Case of 10000 　　Pack of 500 　　1065 mL (36oz.) 3.0 mil 12.7 x 38.1 cm (5 x 15") B00994WA 11216-090 Case of 2000 　　Pack of 500 　　2040.5 mL (69 oz.) 3 mil 19 x 38.1 cm (71/2 x 15") B01323WA 11216-422 Case of 1000 　　Pack of 500 　　118 mL (4oz.) 2.25 mil 7.6 x 18.4 cm (3 x 71/4") B00679WA 11216-012 Case of 10000 　　Pack of 500 　　1242 mL (42oz.) 3.0 mil 15.2 x 38.1 cm (6 x 15") B01027WA 11216-420 Case of 2000 　　Pack of 500 　　VWR® Sterile Opaque Sample Bags 　　Capacity Thickness W x L VWR Catalog Number 　　540 mL (18 oz.) 3 mil 11.4 x 22.9 cm (4 1/2 x 9") 93000-724
