Next Advance Navy Lysis Kits

Extra power for your tough samples. Navy Bead Lysis Kits are filled with a custom mix of stainless-steel beads for buffer volumes between 300 uL and 600 uL. They're great for samples that are too large for a Green Kit and deliver extra homogenizing power for challenging samples like bone, tumors, and hard-shelled insects such as ticks. RINO Safe-lock tube bead lysis kits are made of high-quality polypropylene and are easy to open and close. These tubes can be used in any current microcentrifuge model Bullet Blender®.

Kits are available in RNase-free or non-sterile versions.

*All colors of GATOR Kits are shipped with red silicone plugs.

Custom kits: Made to your specifications. Need a precise mixture of beads to match your SOP or homogenize an unusual sample? We offer Custom kits.

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.
