Revenue from Contract with Customer [Text Block] | Note 2. Revenue We develop, manufacture, market, sell and maintain life sciences tools and quality control instruments and related consumables. Hardware sales include physical products such as instruments used for molecular and genetic analysis, protein synthesizers, medical meters, wireless sensor systems, data loggers, and process challenge devices. Hardware sales may be offered with accompanying perpetual or annual software licenses, which in some cases are required for the hardware to function. Consumables sold by our Clinical Genomics and Biopharmaceutical Development divisions, such as reagents used for molecular and genetic analysis or solutions used for protein synthesis, are critical to the ongoing use of our instruments. Consumables such as biological and chemical indicator test strips sold by our Sterilization and Disinfection Control division are used on a standalone basis. Revenues from hardware and consumables are recognized upon transfer to the customer, typically at the point of shipment. We also offer maintenance, calibration and testing services. Services result in revenues recognized either over time, for example, when we are contractually obligated to perform labor and replace parts on an as-needed basis throughout a specified service period, or at a point in time, upon completion of a specific, discrete service. We evaluate our revenues internally based on business division and the nature of goods and services provided. The following tables present disaggregated revenues for the three and six months ended September 30, 2025 and 2024, respectively:

No foreign country exceeded 10% of total revenues for the three and six months ended September 30, 2025. Contract Liabilities Our contracts have varying payment terms and conditions. Some customers prepay for products and services, resulting in contract liabilities recorded as unearned revenues or within other noncurrent liabilities in our unaudited Condensed Consolidated Balance Sheets. The significant majority of our revenues, related receivables and contract liabilities arise from contracts with original durations of twelve months or less. Contract liabilities are recognized as revenue as we satisfy our obligations under the terms of the contracts. A summary of contract liabilities is as follows:
Contract liabilities as of March 31, 2025 |  | $ | 14,803 |
Prior year liabilities recognized in revenues during the six months ended September 30, 2025 |  |  | (7,312 | )
Contract liabilities added during the six months ended September 30, 2025, net of revenues recognized |  |  | 6,778 |
Contract liabilities as of September 30, 2025 |  | $ | 14,269 |
