Basis of Presentation and Significant Accounting Policies [Text Block]	1. 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 media 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 in the United States (“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 condensed consolidated financial statements included herein have been prepared by BioLife Solutions, Inc. in accordance with GAAP and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), for Quarterly Reports on Form 10 10 X not 10 December 31, 2020.

Fair Value Measurement In accordance with FASB ASC Topic 820, 820” 820 820 three Level 1 Level 2 1 not Level 3 The fair value of the Astero contingent consideration liability was initially valued based on unobservable inputs using a Black-Scholes valuation model. These inputs included the estimated amount and timing of projected future revenue, a discount rate of 17.5%, risk-free rates between 2.29% and 2.41% and revenue volatility of 56%. Significant increases (decreases) in any of those inputs in isolation would result in a significantly higher (lower) fair value measurement. Generally, changes used in the assumptions for projected future revenue and revenue volatility would be accompanied by a directionally similar change in the fair value measurement. Conversely, changes in the discount rate would be accompanied by a directionally opposite change in the related fair value measurement. However, due to the contingent consideration having a maximum payout amount, changes in these assumptions would not December 31, 2020, March 31, 2021 December 31, 2020 may The fair value of the CBS contingent consideration liability was initially valued based on unobservable inputs using a Monte Carlo simulation. These inputs included the estimated amount and timing of projected future revenue, a discount rate of 26.0%, a risk-free rate of approximately 1.74% and revenue volatility of 70%. Significant increases (decreases) in any of those inputs in isolation would result in a significantly higher (lower) fair value measurement. Generally, changes used in the assumptions for projected future revenue and revenue volatility would be accompanied by a directionally similar change in the fair value measurement.

Significant increases (decreases) in any of those inputs in isolation would result in a significantly higher (lower) fair value measurement.

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 in the United States (“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.
