TrippNT Extra Large Draft Shield | 22" Clear Acrylic Cube Balance & Instrument Protection 50240

TrippNT Extra Large Draft Shield — 22″ Clear Acrylic Cube with Downdraft Guard for Wide-Format Balances, Gram Scales, and Large Analytical Instruments

The TrippNT Extra Large Draft Shield (SKU 50240) is the 22-inch cube in TrippNT’s four-size draft shield series, designed for the specific instrument footprint range that the 18-inch Medium (50073) and the 18-inch Large (50046) cannot cover: top-loading and triple-beam balances with wide pan platen frames (12–18 inches), gram-resolution bench scales with large platform surfaces, analytical balances with integral data printers or ionizer modules that extend laterally, refractometer workstations with elevated sample stages, and large-format dissolved oxygen or ion-selective electrode analyzer systems with probe stands extending above the instrument body. At 22″ W × 22″ H × 23¼″ D in 3/16-inch cast clear acrylic, the 50240 provides the largest interior clearance envelope in the standard TrippNT draft shield line, accommodating instrument configurations that would crowd or overhang inside the 18-inch models. The 3-inch downdraft deflecting overhang panel running the full 22-inch front width provides the same top-down HVAC supply air protection that distinguishes the TrippNT series from competing four-sided open-top enclosures, redirecting ceiling diffuser airflow outward rather than allowing it to drop onto the instrument pan or sample stage.

The semicircular cord pass-through on the rear panel routes data communication cables, power cords, and probe leads cleanly without opening a gap in lateral draft protection. Installation is tool-free: set the shield over the instrument, route cords through the rear cutout, and calibrate. The full-perimeter clear acrylic construction allows unobstructed manipulation of samples and instrument controls through the open front panel without disturbing the draft enclosure at the sides and rear. Ships fully assembled, 16 lb. Shippers are strongly advised to use an LTL carrier or padded ground freight service for the 50240 given its mass and glass-format acrylic construction — standard small parcel carriers have documented damage rates on this SKU. For instruments narrower than 16 inches, the 50046 Large 18-inch (LS Batch 02) is the cost-optimized specification.

Technical Specifications

Laboratory and Clinical Applications

The TrippNT 50240 is specified for large-format instrument draft protection in: GMP pharmaceutical and API manufacturing weighing rooms (top-loading balance programs under 21 CFR Part 211, semi-micro through gram-resolution range), ISO 17025-accredited calibration labs (wide-platform mass standard verification), food and beverage QC gravimetric suites (large-format portion and yield measurement), environmental and soil testing labs (large-pan moisture and loss-on-ignition), forensic and controlled substance labs (large-platform controlled substance weighing), industrial quality control bench-scale programs (batch manufacturing in-process weight check), academic teaching labs (gravimetric analysis with top-loading balances), botanical extract and nutraceutical manufacturing QC, large-format refractometer and viscometer bench workstations, aquatic and environmental research instrument stations, and any bench application where an instrument or its accessory footprint exceeds 15 inches in width or 18 inches in height. Also used for protection of pH electrode stands, dissolved CO₂ analyzers, and multi-probe electrochemistry benches where the full instrument assembly height exceeds what the Medium or Large shields cover.

Frequently Asked Questions

When should I specify the 50240 Extra Large (22-inch) instead of the 50046 Large (18-inch)?

The 50046 handles analytical balances with 80–100mm pans and body widths up to approximately 13 inches — which covers the vast majority of 0.1mg and 1mg analytical balance models. Specify the 50240 when the instrument or its accessory assembly exceeds 15 inches in width or 18 inches in height, including: top-loading balances with large platen frames (Mettler Toledo MS16001L, Ohaus Ranger series, Adam Equipment CB series), three-beam balances with side rider arms, gram balances with built-in draft shields that widen the effective footprint, analytical balances with external ionizer modules or anti-static bar attachments, refractometer and viscometer bench setups with elevated sample stages, and pH analyzer systems with electrode stands extending 19″+ above the bench. When in doubt between the 50046 and 50240, measure the instrument body width at its widest point (including all attachments), add 3 inches of clearance per side for manipulation, and choose the shield whose interior exceeds that sum.

Are there shipping precautions for the 50240 given its size and weight?

Yes. The 50240 weighs 16 lb and ships in a 27″ × 27″ × 27″ carton — a cubic-footprint package that exceeds the impact-handling guidelines for standard small parcel carrier (UPS, FedEx Ground) drop-and-sort systems. For procurement teams ordering the 50240 for institutional delivery, we strongly recommend requesting LTL (less-than-truckload) freight or padded ground delivery service from your TrippNT distributor to minimize transit damage risk. The acrylic panels on the 50240 are 3/16-inch cast acrylic — significantly more durable than extruded acrylic alternatives — but all acrylic is susceptible to fracture from point impact at package corners, which standard small-parcel conveyor systems generate. Express delivery services (overnight or 2-day air) with residential or dock delivery protocols typically handle this package size appropriately.
