Petri Dish Plate Stickers

PetriStickers allow for petri dishes to be labeled quickly, neatly and reliably. Made with water-resistant ink, substrate and adhesives and will remain firmly attached at temperatures from 42° to 4°C. Simply remove the label's protective backing and apply it to the back of a petri dish. After labeling, the dish can be held in a comfortable position for streaking or colony transfer, stored in an incubator or refrigerator, and photographed.

PetriSeal™ Sealing Film

PetriSeal™ stretches and conforms to form a tight seal and is temperature resistant, waterproof and chemically resistant. It resists abrasion and puncture and blocks vapor loss while reducing the rate of gas exchange. Use PetriSeal™ with microtiter plates, Petri dishes and culture plates to prevent to entry of contaminants. The seal remains flexible down to -30°C and can withstand continuous exposure from -40°C to +77°C (with intermittent exposure up to 100°C). Tests have shown that PetriSeal™ leaves no adhesive residue even after two years.

Hoefer® Gel Casters

Enable several gradient or homogeneous gels to be cast simultaneously. Choice of multiple-gel casters or dual-gel casters.

Gel Casters for Small Format Vertical Electrophoresis Systems (SE250, SE260, SE300)

Multiple-Gel Casters

• Pour uniform gels from the top; pump gradient gels into an inlet port at the bottom of the unit
• Sandwiches fill at the same time and at the same rate from the same solution
• The result: identical gels
• Glass plate sandwiches seal leak-free without the use of messy grease or tape
• Once cast, gels can be wrapped in plastic and refrigerated for several weeks

Dual-Gel Caster (SE245)

• Cast one or two gels
• Accommodates both 10 x 8 cm and 10 x 10.5 cm plates

*For use with the SE250 and SE260 Series only.
 

Gel Casters for SE600 and SE400 Series Vertical Units   

Multiple-Gel Casters

• SE675 casts up to four 16 cm long gels
• SE615 casts up to ten 16 cm long gels
• Easy to use and leak-free
• Cast homogeneous or gradient gels. Pour homogeneous gels directly into the top of the casting chamber: pump gradient gels through an inlet port at the bottom

Dual-Gel Caster (SE6015)

SE6015 Dual Gel Caster is included when you order an SE600 series unit. It can also be ordered separately.

• Casts two 8, 16, or 24 cm long gels at a time
• Double the capacity with optional divider plates
• Easy to use and leak-free
• Glass Sandwichers seal into the casting 

*For use with the SE600 Series only.
