Products classified under HTS 9033.00.90.00
Instrument Handle Grip Kit
Ergonomic polymer grip sleeves that slip over control knobs, handles, and adjustment levers on various laboratory instruments. Improves operator comfort and reduces fatigue during extended use.
Universal Calibration Weight Set for Optical Instruments
A precision-machined stainless steel set of calibration weights used to verify the accuracy of analytical balances and precision scales classified under heading 9016. These weights are suitable for use with multiple types of laboratory measuring instruments in Chapter 90 but not dedicated to a single specific apparatus. They fall under HTS 9033.00.90.00 as general parts and accessories not specified elsewhere in the chapter.
Adjustable Micrometer Stand Holder
A heavy-duty cast iron base with adjustable arm designed to hold micrometers, calipers, and dial indicators during precision measurements. Compatible with multiple measuring instruments from headings 9017 and 9024. Classifies under 9033.00.90.00 as it serves various Chapter 90 apparatus without principal dedication to one type.
Anti-Vibration Instrument Platform Pad
Granite-filled polymer platform pads that isolate laboratory instruments from building vibrations, suitable for microscopes (9011), balances (9016), and testing machines (9024). These general damping accessories fall under HTS 9033.00.90.00 as they support multiple Chapter 90 categories.
Universal Instrument Dust Cover Set
Customizable transparent plastic covers designed to protect various laboratory measuring instruments from dust and contaminants when not in use. Sized for equipment from multiple Chapter 90 headings including spectrophotometers and chromatographs. Classifies in 9033.00.90.00 as general protective accessories.
Precision Leveling Feet Kit for Lab Instruments
Adjustable stainless steel leveling feet with fine thread adjustment (0.01mm/turn) for aligning analytical instruments on uneven surfaces. Universal design fits baseplates of balances, microscopes, and testing machines throughout Chapter 90.
Multi-Function Instrument Cable Organizer Tray
Modular aluminum tray system for organizing power, data, and signal cables from multiple laboratory instruments. Prevents cable clutter around workbenches with spectrometers, chromatographs, and testing equipment.
Laboratory Instrument Thermal Insulation Blanket
Fiberglass-reinforced silicone blanket (0.5-2mm thick) for maintaining thermal stability of precision instruments during ambient temperature fluctuations. Used on ovens, incubators, and temperature-sensitive analyzers.
Magnetic Instrument Retrieval Tool
Flexible telescoping magnetic retriever for recovering small metal parts, tools, and fasteners dropped inside analytical instruments during maintenance. Essential for servicing spectrometers, balances, and vacuum systems.
