The B2023-GL20 is the gable lid accessory for the myBath CR 20 L Circulating Water Bath (B2023-20) — sold at $119 ($27 premium over the 10 L lid B2023-GL10 at $119.00 reflecting larger lid footprint). Same gable / angled design as the 10 L sister, sized to the 20 L bath's larger chamber footprint.
For full rationale (gable lid evaporation / condensate management, application profile, long-cycle workflow benefit), see the B2023-GL10 (10 L lid) parent page.
Key Specifications

| List price | $119 |
Why the 20 L Lid Matters More Than the 10 L Lid
The 20 L bath has 2× the surface area of the 10 L bath — proportionally higher evaporation rate per unit time under the same operating temperature. The gable lid is even more important on the 20 L bath than on the 10 L:
- Higher evaporation surface = larger bath-volume drift over long cycles
- More additive concentration drift at higher evaporation rate
- More lab-humidity contribution from larger surface
- Larger volume of condensate to manage (gable redirection more important to prevent drip-pattern contamination)
Pick the gable lid (B2023-GL20) when:
- Operating the 20 L circulating bath in any long-cycle workflow (the larger surface area makes lid use more valuable than on the 10 L sister)
- Production-scale workflows with overnight or multi-day cycles
- Temperature-controlled-room procurement of the 20 L bath
- Multi-investigator shared 20 L bath standardizing on lid use
Gable Lid Family — Capacity Match
| SKU | Compatible bath | Bath capacity | Lid list price |
| B2023-GL10 | B2023-10 / -10-E | 10 L | $119.00 |
| B2023-GL20 (this product) | B2023-20 / -20-E | 20 L | $119 |
Ordering & Configuration
Pair with B2023-20 / -20-E chassis. Confirm 20 L bath inventory at order.
Plan for long-cycle bath top-off — even with the lid, periodic bath top-off is required; plan top-off frequency in long-cycle SOP.
Confirm at quote: chassis pairing (specifically 20 L), intended long-cycle workflow context, and lead time.
Warranty: Per Benchmark Scientific standard accessory terms.
myBath CR Circulating Bath gable lid family:
- B2023-GL10 — Gable lid for 10 L bath ($119.00)
- B2023-GL20 (this product) — Gable lid for 20 L bath ($119)
Pick the 20 L lid for the larger circulating bath; the larger surface area makes lid use even more valuable than on the 10 L bath. See B2023-GL10 parent page for full evaporation-management rationale.
