Alkali Scientific PolarPal™ Freezing Container for 1.0 2.0 mL Cryovials, Polycarbonate (PC) 18 Place, 1/Pk

Supplier: Alkali Scientific FC018
The 18 Place Controlled Rate Freezing Container provides a reliable and consistent method for freezing 1.0–2.0 mL cryovials at approximately –1 °C per minute, helping preserve cell viability during cryogenic storage. Designed for convenience and reproducibility, it eliminates improvised freezing methods while ensuring uniform cooling. The container holds up to 18 cryovials (1.0–2.0 mL) and includes a vial holder that prevents direct contact with isopropyl alcohol, protecting sample labels and contents. Clear step by step instructions are printed directly on the unit for quick setup. Its compact design (117 mm diameter × 86 mm height) saves valuable freezer space, while the screw top lid keeps vials secure during handling or transport. The reusable system requires only 250 mL of 100% isopropyl alcohol and a –70 °C to –80 °C mechanical freezer for consistent results.
