iSonic P4875-NH Ultrasonic Cleaner – 2 Gallon (7.5 L) Commercial Instrument Cleaning

The iSonic P4875-NH is a commercial-grade ultrasonic cleaner built for dental, surgical, and veterinary instrument reprocessing. Three independently driven stack transducers deliver uniform cavitation across the full 2-gallon tank, driving cleaning solution into hinges, box locks, serrations, and internal surfaces that manual brushing cannot reach.

The 7.5 L stainless steel tank accommodates full-size 7¾" × 11" dental cassettes, so instruments are processed as complete setups rather than broken down into loose pieces. Through DentalMarketplace, the P4875-NH ships with the SOB4875A stainless steel basket included and a 1-year manufacturer warranty on parts and labor.

Key Features and Benefits

• Three stack transducers with independent PCB control: Up to 40% more ultrasonic power than shared-circuit designs, with balanced energy distribution across the tank.
• 2 Gal / 7.5 L stainless steel tank: 13" × 9.4" × 4.1" interior fits full-size dental and surgical cassettes.
• Degas function: Removes trapped air from fresh solution so cavitation reaches full effectiveness from the start of the cycle.
• Quick-timer memory recall: Remembers your last cycle setting – no resetting between loads.
• Raised control panel housing: Elevated design prevents moisture intrusion into the controls during extended operation.
• Three cooling fans: Improved heat dissipation supports back-to-back cycles through a busy turnover schedule.
• Drainage valve: Empties the tank cleanly without lifting or tipping the unit.
• 35,000 Hz operating frequency: Well suited to fine dental and surgical instrumentation.
• Standard 110V power: Operates on a normal U.S. outlet with no special electrical installation.
• Stainless steel basket included: The SOB4875A one-piece basket ships with the unit.

Instrument Reprocessing Workflow

Ultrasonic cleaning determines whether sterilization succeeds. Residual debris shields microorganisms from steam contact, so cassettes entering the autoclave unclean may come out unsterile. The P4875-NH is sized to process cassetted instruments as a unit – the way most practices already work.

• Reduces hands-on contact with contaminated sharps during pre-cleaning
• Processes full-size cassettes without disassembly, preserving setup integrity
• Cleans hinges, box locks, and serrations that hand scrubbing misses
• Supports consistent, documented infection-control protocols
• Frees staff for other tasks during the cleaning cycle

Why Choose the P4875-NH

Most 2-gallon ultrasonic cleaners in this class run a single shared control circuit across their transducers. The P4875-NH gives each of its three stack transducers an independent PCB, which is what produces the 40% power advantage and the even cavitation field. Add the degas cycle, memory timer, drain valve, and raised control housing, and you have a unit built for daily clinical turnover rather than occasional use.

• Commercial-grade construction rated for repeated daily clinical use
• Fits full-size 7¾" × 11" cassettes as standard
• No-heater (NH) configuration, appropriate where heat is not wanted in the protocol
• If your practice runs Hu-Friedy Large Thin Ortho Cassettes (8.2" × 11"), the plus-size SOB8.0A basket or the P4875-NH-8 model covers that wider format

Ideal For

• Dental practices and orthodontic offices running cassette-based processing
• Oral surgery and periodontal practices
• Sterilization and instrument reprocessing areas
• Veterinary clinics and specialty medical tools
• Dental and research laboratories
• Tattoo and piercing studios

Compatible Accessories

The following iSonic accessories fit the P4875-NH. Contact DentalMarketplace to add any of these to your order.

• SOB4875A – One-piece stainless steel basket. Included with this unit. Available separately as a replacement or spare.
• SOB8.0A – Plus-size 8.3" wide stainless steel basket. Upgrades the unit to accept Hu-Friedy Large Thin Ortho Cassettes (8.2" × 11") and other plus-size trays.
• IT4875A – Stainless steel removable cleaning chamber. Isolates corrosive or costly solutions from the main tank; also used for IPA cleaning of 3D printed parts. Approximate inside dimensions 4.75" × 8.75" × 3.25".
• IT8.0A – Large stainless steel removable cleaning chamber, for a bigger single working volume.
• BHK02A – Double beaker holder set with two 500 ml beakers, for small-item and solution-specific cleaning.
• PB4875A – Suspendable plastic basket for delicate items.
• SRB4875A – Stainless steel rack and basket combination for additional loading configurations.

Stainless steel baskets absorb less ultrasonic energy than plastic, generally producing better cleaning results and lasting longer.
