Product Description
DILVAC™ Portable Dry Ice Block Maker
Make a 2.2-lb dry-ice block in ~1 minute, on demand!
For biotech, clinical diagnostics, drug development, food safety, and shipping teams that are done scrambling for deliveries and watching dry ice sublimate away. No electricity required—just a liquid CO₂ cylinder with a siphon tube and the appropriate hose connection on the valve.
Applications
-
Snap-freezing tissue and clinical samples; cold-chain handoffs
-
Reaction quenching, solvent/dry-ice baths
-
On-site packaging for cold shipment
Why labs choose this unit
-
Fast: ~1 kg (2.2 lb) block in about 1 minute.
-
Cost control: Typical yield 5–6 blocks per 75-lb liquid CO₂ cylinder at room temp (Pro Tip: yields more at cooler temps).
-
Simple and reliable: Manual operation—no power or moving parts. Comes with steel pressure hose and gauge.
-
Compact: Small footprint; store under a bench or on a shelf.
How it works (4 steps)
-
Connect the pressure hose to a liquid CO₂ cylinder with siphon and CGA-320 valve.
-
Open the CO₂ flow and monitor on the gauge.
-
Dry ice forms inside the chamber; vapor vents through the slots while the block compacts.
-
After ~1 minute, open the front, remove the solid block.

Safety
-
Use appropriate PPE (cryogenic gloves, apron, goggles/face shield).
-
Ensure good ventilation; avoid CO₂ buildup. Gaseous CO2 vapours can cause suffocation, so use the unit only in well-ventilated areas.
-
To avoid cryogenic liquid spillage, use the unit only on a level supporting surface, and never allow the unit to hang from the feed hose.
-
Open cylinder valve slowly and follow gauge guidance in the manual (e.g., keep within inner-scale ranges to avoid waste).
-
Only use liquid-withdrawal cylinders (with siphon).

FAQ
Q: What kind of CO₂ cylinder do I need?
A: A liquid CO₂ cylinder with an internal siphon. (Standard gas-withdrawal cylinders won’t work.)
Q: How many blocks per cylinder?
A: Typically produces 5–6 blocks from a 75-lb cylinder at room temperature; cooler ambient temps can increase yield, i.e. @ 5°C (41°F) approximately 1/3 more blocks produced.
Q: Do I need electricity or compressed air?
A: No, this unit is manual and requires only the liquid CO₂ cylinder.
Q: What size block does it make?
A: About 7.0" × 3.2" × 4.3", weighing about 1kg (2.2 lbs.),
Q: Is it a solid block or slush?
A: A solid block (not slush).
