Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Estimates: The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates include the valuation of accounts receivable, available-for-sale investments, inventory, intangible assets, stock based compensation and income taxes. Actual results could differ from these estimates.
Consolidation, Policy [Policy Text Block]	Principles of consolidation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Translation of foreign financial statements: Assets and liabilities of the Company’s foreign operations are translated at year-end rates of exchange and the resulting gains and losses arising from the translation of net assets located outside the U.S. are recorded as other comprehensive income (loss) on the consolidated statement of earnings and comprehensive income. The cumulative translation adjustment is a component of accumulated other comprehensive income (loss) on the consolidated balance sheets. Foreign statements of earnings are translated at the average rate of exchange for the year. Foreign currency transaction gains and losses are included in other non-operating expense in the consolidated statements of earnings.
Revenue Recognition, Policy [Policy Text Block]	Revenue recognition: The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable and collectability is reasonably assured. Payment terms for shipments to end-users are generally net 30 days. Payment terms for distributor shipments may range from 30 to 90 days. Freight charges billed to end-users are included in net sales and freight costs are included in cost of sales. Freight charges on shipments to distributors are paid directly by the distributor. Any claims for credit or return of goods must be made within 10 days of receipt. Revenues are reduced to reflect estimated credits and returns. Sales, use, value-added and other excise taxes are not included in revenue.
Research and Development Expense, Policy [Policy Text Block]	Research and development: Research and development expenditures are expensed as incurred. Development activities generally relate to creating new products, improving or creating variations of existing products, or modifying existing products to meet new applications.
Advertising Costs, Policy [Policy Text Block]	Advertising costs: Advertising expenses (including production and communication costs) were $4.1 million, $3.4 million, and $3.2 million for fiscal 2015, 2014, and 2013, respectively. The Company expenses advertising expenses as incurred.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Share-based compensation: The cost of employee services received in exchange for the award of equity instruments is based on the fair value of the award at the date of grant. Separate groups of employees that have similar historical exercise behavior with regard to option exercise timing and forfeiture rates are considered separately in determining option fair value. Compensation cost is recognized using a straight-line method over the vesting period and is net of estimated forfeitures. Stock option exercises and stock awards are satisfied through the issuance of new shares.
Income Tax, Policy [Policy Text Block]	Income taxes: The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized to record the income tax effect of temporary differences between the tax basis and financial reporting basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Tax positions taken or expected to be taken in a tax return are recognized in the financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Financial instruments not measured at fair value : Certain of the Company’s financial instruments are not measured at fair value but nevertheless are recorded at carrying amounts approximating fair value, based on their short-term nature. These financial instruments include cash and cash equivalents, accounts receivable, accounts payable and other current liabilities.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and equivalents: Cash and cash equivalents include cash on hand and highly-liquid investments with original maturities of three months or less.
Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]	Available-for- sale investments: Available-for-sale investments consist of debt instruments with original maturities of generally three months to three years and equity securities. Available-for-sale investments are recorded based on trade-date. The Company considers all of its marketable securities available-for-sale and reports them at fair value. The Company utilizes valuation techniques for determining fair market value which maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date. Unrealized gains and losses on available-for-sale securities are excluded from income, but are included, net of taxes, in other comprehensive income. If an “other-than-temporary” impairment is determined to exist, the difference between the value of the investment security recorded in the financial statements and the Company’s current estimate of the fair value is recognized as a charge to earnings in the period in which the impairment is determined.
Inventory, Policy [Policy Text Block]	Inventories: Inventories are stated at the lower of cost (first-in, first-out method) or market. The Company regularly reviews inventory on hand for slow-moving and obsolete inventory, inventory not meeting quality control standards and inventory subject to expiration. To meet strict customer quality standards, the Company has established a highly controlled manufacturing process for proteins, antibodies and its chemically-based products. These products require the initial manufacture of multiple batches to determine if quality standards can be consistently met. In addition, the Company will produce larger batches of established products than current sales requirements due to economies of scale. The manufacturing process for these products, therefore, has and will continue to produce quantities in excess of forecasted usage. The Company values its manufactured protein and antibody inventory based on a two-year forecast and its chemically-based products on a five-year forecast. Inventory quantities in excess of the forecast are not valued due to uncertainty over salability. Sales of previously unvalued protein, antibody and chemically-based inventory for fiscal years 2015, 2014, and 2013 were not material.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and equipment: Property and equipment are recorded at cost. Equipment is depreciated using the straight-line method over an estimated useful life of five years. Buildings, building improvements and leasehold improvements are amortized over estimated useful lives of 5 to 40 years. Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. In the current year, the Company has identified no such events.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill: At June 30, 2015 and 2014, the Company had recorded goodwill of $390.6 million and $151.5 million, respectively. The Company tests goodwill at least annually for impairment. The Company completed its annual impairment testing of goodwill and concluded that no impairment existed as of June 30, 2015.
Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]	Intangible assets: Intangible assets are being amortized over their estimated useful lives. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. In the current year, the Company has identified no such events.
Equity Method Investments, Policy [Policy Text Block]	Investments in unconsolidated entities: The Company has equity investments in several start-up and early development stage companies. The accounting treatment of each investment (cost method or equity method) is dependent upon a number of factors, including, but not limited to, the Company’s share in the equity of the investee and the Company’s ability to exercise significant influence over the operating and financial policies of the investee.
