Which Corning conical tube line is which?
Corning sells several 50 mL conical tube families under different names — check the catalog number before comparing:
| Falcon 50 mL PP conical (e.g., 352070 / 352098) | 16,000 x g max RCF; flat-top screw cap with double-threaded design that reduces cross-threading and leakage (per Corning’s published catalog) |
| CentriStar 50 mL (430828) | 17,000 x g max RCF; HDPE CentriStar cap with leak-proof plug feature (see the 430828 page) |
| Plug-seal 50 mL (430290) | 15,500 x g max RCF; plug seal cap, pressure tested at 95 kPa / 14 psi (see the 430290 page) |
Price per item vs case price
Case prices across suppliers are hard to compare because pack counts differ. Normalize first: price per item = case price ÷ pack count. For example, a 500-tube case and a 25-tube sleeve can look very different until both are converted to price per tube, and public list prices exclude freight and contract terms.
We quote delivered price per item — send your catalog numbers and destination, and we return a per-tube price including freight. Request a quote.
Corning 4488 vs 4489: capacity and pack quantity
Corning lists 4488 as a 10 mL serological pipet and 4489 as a 25 mL serological pipet. Both use individually wrapped paper/plastic packaging and are listed as 200 per case, while the number per pack differs.
| Catalog number | Capacity | Per pack | Per case |
|---|---|---|---|
| 4488 | 10 mL | 50 | 200 |
| 4489 | 25 mL | 25 | 200 |
