Heathrow Scientific Polypropylene Film Cryogenic Freezer Box 81-Place - 120370 Series | Waterproof, -80°C

When your lab needs a cryobox that splits the difference between rigid molded polypropylene and economical cardboard, polypropylene film construction delivers waterproof durability at a competitive price point. The Heathrow Scientific Polypropylene Film Cryogenic Freezer Box holds 81 microcentrifuge tubes (1.5/2.0 mL) in a 9 × 9 grid with 12.1 mm wells, housed in a lightweight film-construction body that resists moisture damage throughout its service life. Rated to −80 °C, these boxes fit standard 5-inch freezer rack bays and ship in packs of 10 with four color options — White, Blue, Purple, and Light Green — for color-coded organization across sample categories, research groups, or project timelines.

Features and Benefits

• 81-Place Grid (9 × 9): Holds up to 81 microcentrifuge tubes (1.5 mL / 2.0 mL) or standard cryogenic vials in 12.1 mm wells.

• Polypropylene Film Construction: Lightweight, moisture-proof material that outlasts cardboard without the higher cost of rigid molded plastic.

• −80 °C Rated: Reliable in ultra-low temperature mechanical freezers and dry-ice transport containers.

• Four Color Options: White, Blue, Purple, and Light Green enable color-coded organization across freezer inventories.

• Standard Cryobox Footprint: 5.0 × 4.9-inch base fits standard upright and chest freezer racks.

• 10-Pack Value: Economical bulk packaging for labs that consume cryoboxes at high volume.

Specifications

Laboratory Applications

• Mid-budget cryogenic storage for labs that need waterproof boxes without the premium cost of rigid molded polypropylene or polycarbonate

• Color-coded biobanking systems where four color options enable visual segregation of specimen types, collection dates, or responsible investigators

• High-volume sample archiving in academic and contract research organizations that consume dozens of cryoboxes per month

Frequently Asked Questions

What is the difference between PP film and standard molded PP cryoboxes?
PP film boxes use thinner polypropylene sheet material — they are lighter and less expensive per box than rigid molded PP. They are waterproof and −80 °C rated like molded PP, but less impact-resistant and typically not autoclavable.

Are these boxes autoclavable?
PP film construction is generally not recommended for autoclave temperatures. For autoclavable storage, use the Heathrow molded polypropylene 81-Well Tube Storage Boxes (120034 Series).

Do these fit standard 5-inch freezer racks?
The 5.0 × 4.9-inch footprint fits most standard freezer rack bays. The slightly smaller footprint compared to a 5.2-inch standard box means they may have minor lateral play in some racks — this is normal and does not affect storage integrity.

Quality Assurance

Heathrow Scientific polypropylene film cryogenic boxes are inspected for moisture resistance, well-diameter accuracy, and lid-fit consistency across every production lot.
