The IPD4400-B400 is the standard sterile blender bag for the Benchmark Industrial BenchMasher 400 Paddle Blender (IPD4400) — sold as 500-pack (10 packs of 50 bags). Bag spec: 400 mL volume × 60 µm wall thickness, 300 × 180 mm dimensions, no filter (standard homogenization workflow without filtrate-side separation).

When to Pick the Standard Bag vs Filter-Bag Variants
| SKU | Filter | Best for |
| IPD4400-B400 (this product) | No filter | Standard homogenization workflow; sample recovery through bag opening; downstream filtration as a separate step |
| IPD4400-B400F1 | Lateral / side nylon filter | Side-filter sample-prep where filtrate is recovered through the side filter (typical pathogen / microbial detection workflow) |
| IPD4400-B400F2 | Full nylon filter | Full-filter sample-prep where homogenate is fully filtered before recovery |
Pick the standard bag (IPD4400-B400) when: the workflow does not require filtrate-side separation during the blending step — homogenize, then transfer to filtration / centrifugation / extraction step.
Pick the F1 / F2 filter bags when: the workflow integrates the filtration step into the blending bag (typical regulated food / water pathogen detection workflows where the filtrate is the analytical sample).
Pack Economics
The 500-bag pack at $101 = $0.20 per bag. Standard bags are the lowest-cost variant in the BenchMasher 400 bag family ($0.20 vs $0.82 for F1 vs $1.01 for F2 per bag) — pick when workflow doesn't need filter integration.
Application Profile
Standard sample homogenization — workflows where bag homogenization is followed by separate filtration / processing.
Powder and polymer mixing — non-aqueous homogenization workflows where filter integration is not required.
Large solid sample breakdown — meat / produce / soil sample homogenization for downstream extraction workflows.
Cannabis sample prep — homogenization of cannabis material for downstream testing.
Forensic sample homogenization — contamination-free standard-bag workflow for forensic chain-of-custody.
QuEChERS sample prep — pesticide / contaminant analysis where the standard bag supports the homogenization step before downstream sorbent / extraction processing.
Multi-sample workflows at scale — production sample-prep facilities benefit from the 500-pack bulk procurement at the lowest per-bag cost.
BenchMasher 400 Blender Bag Family
| SKU | Filter type | List price | Per-bag cost |
| IPD4400-B400 (this product) | None (standard) | $101 | $0.20 |
| IPD4400-B400F1 | Lateral nylon filter | $409 | $0.82 |
| IPD4400-B400F2 | Full nylon filter | $503 | $1.01 |
Ordering & Configuration
Per-sample workflow consumable. Each homogenization run consumes one bag. Plan procurement to match workflow per-month or per-quarter sample throughput.
Pair with chassis inventory. The IPD4400-B400 is chassis-specific to the BenchMasher 400 — confirm IPD4400 chassis inventory at order.
Storage. Bags ship sterile in sealed packs; store in original packaging at room temperature until use.
Confirm at quote: chassis pairing (IPD4400 in inventory), workflow filter requirements (standard vs F1 / F2), pack-quantity needs, and lead time.
Warranty: Per Benchmark Industrial standard consumable terms — confirm at quote.
