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

　　VWR® Reusable Inoculating Loops and Needles 　　Inoculating loops and needles are constructed of high-quality, economic nichrome wire that cools rapidly after sterilization. Loops slide along agar surfaces without cutting or tearing. Loops are available with or without lightweight aluminum handles, which are insulated for hand protection. Reusable needles feature lightweight, insulated aluminum handles and are ideal for selecting, inoculating, or transferring microbiological samples. Loop holders are constructed of insulated nickel-plated brass. 　　Calibrated loops are supplied with certificates based on ASM/APHA Evans blue dye test protocols. 　　Loop Holders 　　Description VWR Catalog Number Unit 　　15.2 cm (6") Long 80094-482 Each 　　Pack of 10 　　20.3 cm (8") Long 80094-484 Each 　　Pack of 10 　　Loops 　　Description Size VWR Catalog Number Unit 　　Calibrated without Handles 1 µL 80094-496 Pack of 5 　　Without Handles 3.6 mm I.D. 80094-480 Pack of 25 　　Calibrated without Handles 10 µL 80094-494 Pack of 5 　　Calibrated Streaker with Handles 10 µL 80094-492 Each 　　Pack of 5 　　Streaker with Handles 2.5 mm I.D 80094-490 Pack of 5 　　Streaker with Handles 5.5 mm I.D. 80094-486 Pack of 5 　　Without Handles 3 mm I.D. 80094-478 Pack of 25 　　Streaker with Handles 3.5 mm I.D. 80094-488 Pack of 5 　　Without Handles 2.3 mm I.D. 80094-476 Pack of 25 　　Needles 　　Description VWR Catalog Number Unit 　　With 20.3 cm (8") Handle 80094-504 Pack of 5 　　Angled with 15.2 cm (6") Handle 80094-507 Each 　　Straight with 15.2 cm (6") Handle 80094-498 Each 　　With No Handle 80094-508 Pack of 12 　　VWR® Inoculating Loops and Needles, Sterile 　　High-impact polystyrene loops and needles are smooth and flexible to facilitate uniform and smooth streaking without damaging the gel surface. Needles are straight and suitable for removal of single colony specimens. Packed sterile in safe, tamperproof, zip-seal resealable bags. Disposable inoculating loops and needles do not need flaming, eliminating the risk of infection due to aerosol formation of pathogenic substances as well as cross-contamination due to improper sterilization. Loops and needles can be used under hoods without danger. Color-coded for easy size identification. Total length: 22.7cm (87/8"). 　　Description Size Color Packaging VWR Catalog Number Unit 　　Loops 1 µL Blue 1/Bag 89126-870 Case of 250 　　Loops 1 µL Blue 10/Bag 12000-808 Case of 1,000 　　Loops 1 µL Blue 25/Bag 12000-806 Case of 1,000 　　Loops 10 µL Yellow 1/Bag 89126-872 Case of 250 　　Loops 10 µL Yellow 10/Bag 12000-812 Case of 1,000 　　Loops 10 µL Yellow 25/Bag 12000-810 Case of 1,000 　　Needles none White 1/Bag 89126-868 Case of 250 　　Needles none White 10/Bag 12000-816 Case of 1,000 　　Needles none White 25/Bag 12000-814 Case of 1,000 　　VWR Signature™ Inoculating Loops and Needles, Sterile 　　Calibrated disposable polystyrene inoculation loops and needles.
