EZ BioResearch Bacteria Science Kit (IV) (Gift Pack): Prepoured LB-Agar Plates And Cotton Swabs. Exclusive Free Science Fair Project E-Book Packed With Award Winning Experiments. (IV Gift Pack)

BACKGROUND INFORMATION:
LB stands for Luria Broth, a nutritionally rich medium, which is one of the most common media used in the laboratories worldwide.
LB medium is recommended safe for student use, whereas Tryptic Soy Agar medium is NOT suitable for student use due to its ability to amplify blood-borne pathogenic bacteria.

KIT CONTENT:

1) 10x Pre-poured sterile LB-agar plates (100 x 15 mm Petri Dish)
2) 10x 6-inch sterile cotton swabs (2 per pouch)
3) Detailed Instruction
4) Free Science Fair Project E-Book

LB agar plates should be placed in a refrigerator upon arrival. LB-agar plates stored under such conditions have a minimum shelf life of 3 months.

BRIEF INSTRUCTION:
1) Take out one sterile cotton swab. Gently wipe a test area with the cotton swab to pick up bacteria. Here are some of the popular samples of the test objects: human or pet teeth, hands, phone, TV remote, restaurant menu, sink, floor, fruit, vegetable etc.
2) Take out one of the agar plates (No warm-up is needed). Open the agar plate and gently streak the agar plate with the cotton swab to transfer the bacteria onto the surface of the agar plate.
3) Cover the agar plate and place it in an upside-down position in an incubator with a temperature between 85 and 100 oF. A desk lamp or a portable heater can be used as a heat source.
4) Watch appearance of small bacterial colonies on the surface of the agar plates after 12-48 hr of incubation.

LIVE TECHNICAL SUPPORT:
EZ Prepoured LB agar plates are backed by our 100% money back guarantee. If more technical assistance is needed, we not only provide you with an email address but also a telephone number to talk to our friendly laboratory tech support.

Product Features

  • THE #1 BEST SELLING BACTERIA SCIENCE KIT ON AMAZON: Professional quality products and services at unbeatable prices! Lots of science fair competition awards! We offer 100% money back guarantee.
  • THE SAFEST AGAR PLATES ON AMAZON: Luria Broth(LB) agar plates are used to grow environmental bacteria. By contrast, Tryptic Soy(TS) agar plates are used to grow pathogenic bacteria from clinic patients. TS agar plates will grow blood-borne bacteria which are very dangerous in unprotected environments such as home and school. The amplified blood-borne bacteria could infect other family members, students and teachers. Be aware of the hidden health risk when using TS agar plates!
  • BIOTECH QUALITY, FRESH AND READY-TO-USE: Factory-direct fresh 10 100-mm Pre-poured sterile LB-agar plates and 10 sterile 6-inch long swabs (in 5 pouches). Our plates are manufactured using the biotech GMP standards. Each plate has a fresh and thick layer of agar. Fresh plates promote faster and more bacterial growth as compared to aged stored plates. Re-sealable packaging convenient for re-use.
