MUHWA Tube Rack Double Panel 96-Well Polypropylene PCR Centrifuge Tube Holder for Microcentrifuge Tubes 0.2/0.5/1.5/1.8/2.0ml

MUHWA 96-Well Reversible Double Panel Tube Rack — Polypropylene

Two well diameters in one rack: 7.7 mm on one side, 11.4 mm on the other. The 7.7 mm side holds 0.2/0.5 mL PCR and microcentrifuge tubes; flip to the 11.4 mm side for 1.5/1.8/2.0 mL microcentrifuge tubes.

How the Double Panel Works

Each side carries a 96-well grid. The 7.7 mm side accepts 0.2 mL PCR strips and 0.5 mL microcentrifuge tubes. The 11.4 mm side seats 1.5 mL and 2.0 mL tubes with light friction for stability. Raised rims between wells prevent adjacent tubes from touching when uncapped.

Polypropylene — Built for Wet-Lab Conditions

Solid injection-molded PP throughout. Handles autoclave cycles at 121 °C without warping. Resists ethanol, isopropanol, dilute acids, and alkaline solutions. Unlike acrylic, PP does not craze with alcohol exposure.

FAQ

Q: Can I use both sides at once?
A: No, the rack sits on one face. Keep two racks for workflows switching between tube sizes.

Q: Does this rack float?
A: No. For water baths use our floating tube racks.

Q: Safe for −80 °C?
A: PP becomes brittle below −20 °C. Use polycarbonate cryoboxes for cryogenic storage.
