Basis of Presentation and Significant Accounting Policies [Text Block]	1. Organization and Significant Accounting Policies Business BioLife Solutions, Inc. (“BioLife,” “us,” “we,” “our,” or the “Company”) is a developer, manufacturer and supplier of a portfolio of bioproduction tools and services including; proprietary biopreservation media, automated thawing devices, cloud-connected shipping containers, freezer technology, and biological and pharmaceutical materials storage for cell and gene therapies. Our CryoStor® freeze media and HypoThermosol® hypothermic storage are optimized to preserve cells in the regenerative medicine market. These novel biopreservation media products are serum-free and protein-free, fully defined, and are formulated to reduce preservation-induced cell damage and death. Our ThawSTAR® product line is comprised of a family of automated thawing devices for frozen cell and gene therapies packaged in cryovials and cryobags. These products administer temperature-sensitive biologic therapies to patients by standardizing the thawing process and reducing the risks of contamination and overheating, which are inherent with the use of traditional water baths. Our evo shipping containers provide cloud-connected passive storage and transport containers for temperature-sensitive biologics and pharmaceuticals. Our cryogenic freezer technology provides for controlled rate freezing and storage of biologic materials. Our biological and pharmaceutical materials storage services provide facilities that allow for real-time tracking of materials that can be stored at a wide range of temperatures. Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates and assumptions by management affect the Company’s allowance for doubtful accounts, the net realizable value of inventory, fair value of warrant liability, valuation of market based awards, valuations and purchase price allocations related to investments and business combinations, expected future cash flows including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets, estimated fair values of intangible assets and goodwill, amortization methods and periods, certain accrued expenses, share-based compensation, contingent consideration from business combinations, tax reserves and recoverability of the Company’s net deferred tax assets, and related valuation allowance. The Company regularly assesses these estimates, however, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Basis of presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Astero Bio Corporation (“Astero” or “ThawStar” acquired on April 1, 2019), August 8, 2019), November 12, 2019), October 1, 2020).

Lease accounting We determine if an arrangement is a lease at inception. Where an arrangement is a lease, we determine if it is an operating lease or a finance lease. At lease commencement, we record a lease liability and corresponding right-of-use (“ROU”) asset. Lease liabilities represent the present value of our future lease payments over the expected lease term which includes options to extend or terminate the lease when it is reasonably certain those options will be exercised. The present value of our lease liability is determined using our incremental collateralized borrowing rate at lease inception. ROU assets represent our right to control the use of the leased asset during the lease and are recognized in an amount equal to the lease liability for leases with an initial term greater than 12 We elected to apply the practical expedient for short-term leases and accordingly do not We adopted ASU 2016 02 842 January 1, 2019. Income taxes We account for income taxes using an asset and liability method which generally requires recognition of deferred tax assets and liabilities for the expected future tax effects of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are recognized for the future tax effects of differences between tax bases of assets and liabilities, and financial reporting amounts, based upon enacted tax laws and statutory rates applicable to the periods in which the differences are expected to affect taxable income. We evaluate the likelihood of realization of deferred tax assets and provide an allowance where, in management’s opinion, it is more likely than not not We determine any uncertain tax positions based on a determination of whether and how much of a tax benefit taken in the Company’s tax filings or positions is more likely than not Judgment is applied in the determination of the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return.

Stock-based compensation We measure and record compensation expense using the applicable accounting guidance for share-based payments related to stock options, time-based restricted stock, market-based restricted stock awards and performance-based restricted stock awards granted to our directors and employees. The fair value of stock options, including performance awards, without a market-based condition is determined by using the Black-Scholes option-pricing model. The fair value of restricted stock awards with a market condition is estimated, at the date of grant, using the Monte Carlo Simulation model. The Black-Scholes and Monte Carlo Simulation valuation models incorporate assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. In valuing our stock options, significant judgment is required in determining the expected volatility of our common stock. Expected volatility for stock options is based on the historical and implied volatility of our own common stock while the volatility for our restricted stock awards with a market condition is based on the historical volatility of our own stock and the stock of companies within our defined peer group. Further, our expected volatility may We expense stock-based compensation for stock options, restricted stock awards, and performance awards over the requisite service period. For awards with only a service condition, we expense stock-based compensation using the straight-line method over the requisite service period for the entire award. For awards with a market condition, we expense the grant date fair value over the vesting period regardless of the value that the award recipients ultimately receive. Business combinations, goodwill and intangible assets Business Combinations The Company accounts for business acquisitions using the acquisition method as required by FASB ASC Topic 805, The Company’s identifiable assets acquired and liabilities, including identified intangible assets, assumed in a business combination are recorded at their acquisition date fair values. The valuation requires management to make significant estimates and assumptions, especially with respect to long-lived and intangible assets. Critical estimates in valuing intangible assets include, but are not ● future expected cash flows, including revenue and expense projections; ● discount rates to determine the present value of recognized assets and liabilities and; ● revenue volatility to determine contingent consideration using option pricing models The Company’s estimates of fair value are based upon assumptions it believes to be reasonable, but that are inherently uncertain and unpredictable. Assumptions may may Goodwill is calculated as the excess of the acquisition price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Acquisition-related costs, including advisory, legal, accounting, valuation, and other costs, are expensed in the periods in which these costs are incurred. The results of operations of an acquired business are included in the consolidated financial statements beginning at the acquisition date. The Company estimates the acquisition date fair value of the acquisition-related contingent consideration using various valuation approaches, including option pricing models, as well as significant unobservable inputs, reflecting the Company’s assessment of the assumptions market participants would use to value these liabilities. The fair value of the contingent consideration is remeasured each reporting period.

Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates and assumptions by management affect the Company’s allowance for doubtful accounts, the net realizable value of inventory, fair value of warrant liability, valuation of market based awards, valuations and purchase price allocations related to investments and business combinations, expected future cash flows including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets, estimated fair values of intangible assets and goodwill, amortization methods and periods, certain accrued expenses, share-based compensation, contingent consideration from business combinations, tax reserves and recoverability of the Company’s net deferred tax assets, and related valuation allowance. The Company regularly assesses these estimates, however, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances.

Share-based Payment Arrangement [Policy Text Block]	Stock-based compensation We measure and record compensation expense using the applicable accounting guidance for share-based payments related to stock options, time-based restricted stock, market-based restricted stock awards and performance-based restricted stock awards granted to our directors and employees. The fair value of stock options, including performance awards, without a market-based condition is determined by using the Black-Scholes option-pricing model. The fair value of restricted stock awards with a market condition is estimated, at the date of grant, using the Monte Carlo Simulation model. The Black-Scholes and Monte Carlo Simulation valuation models incorporate assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. In valuing our stock options, significant judgment is required in determining the expected volatility of our common stock. Expected volatility for stock options is based on the historical and implied volatility of our own common stock while the volatility for our restricted stock awards with a market condition is based on the historical volatility of our own stock and the stock of companies within our defined peer group. Further, our expected volatility may We expense stock-based compensation for stock options, restricted stock awards, and performance awards over the requisite service period. For awards with only a service condition, we expense stock-based compensation using the straight-line method over the requisite service period for the entire award. For awards with a market condition, we expense the grant date fair value over the vesting period regardless of the value that the award recipients ultimately receive.
Business Combinations Policy [Policy Text Block]	Business Combinations The Company accounts for business acquisitions using the acquisition method as required by FASB ASC Topic 805, The Company’s identifiable assets acquired and liabilities, including identified intangible assets, assumed in a business combination are recorded at their acquisition date fair values. The valuation requires management to make significant estimates and assumptions, especially with respect to long-lived and intangible assets. Critical estimates in valuing intangible assets include, but are not ● future expected cash flows, including revenue and expense projections; ● discount rates to determine the present value of recognized assets and liabilities and; ● revenue volatility to determine contingent consideration using option pricing models The Company’s estimates of fair value are based upon assumptions it believes to be reasonable, but that are inherently uncertain and unpredictable. Assumptions may may Goodwill is calculated as the excess of the acquisition price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Acquisition-related costs, including advisory, legal, accounting, valuation, and other costs, are expensed in the periods in which these costs are incurred. The results of operations of an acquired business are included in the consolidated financial statements beginning at the acquisition date. The Company estimates the acquisition date fair value of the acquisition-related contingent consideration using various valuation approaches, including option pricing models, as well as significant unobservable inputs, reflecting the Company’s assessment of the assumptions market participants would use to value these liabilities. The fair value of the contingent consideration is remeasured each reporting period. During the measurement period, which may one
