(to Prospectus dated October 8, 2014)

(i) 1,322,500 shares of Common Stock and 1,322,500 Series B Warrants, issuable upon the exercise of the
1,322,500 outstanding Series A Warrants issued in our initial public offering;

and

 (ii) 1,322,500 shares of Common Stock, issuable upon the exercise of the 1,322,500 Series B Warrants that

This prospectus supplement supplements the prospectus dated October 8, 2014, as supplemented by prospectus supplement No. 1 dated November 14, 2014, prospectus supplement No. 2 dated March 6, 2015, and prospectus supplement No. 3 dated April 20, 2015 (collectively, the “Prospectus”), which relates to the offering of the securities of Great Basin Scientific, Inc. (the “Company,” “we,” or “our”) that are underlying the Series A Warrants that we issued in our initial public offering, which closed on October 15, 2014 (our “IPO”). The securities underlying the Series A Warrants include (i) 1,322,500 shares of our common stock and 1,322,500 of our Series B Warrants, which are issuable upon the exercise of the 1,322,500 outstanding Series A Warrants that we issued in our IPO, and (ii) 1,322,500 shares of our common stock, which are issuable upon the exercise of the 1,322,500 Series B Warrants that are issuable under this Prospectus..

Each Series A Warrant is exercisable for one share of common stock and one Series B Warrant. The Series A Warrants were initially exercisable at an exercise price of $7.00 per share; however, as a result of the offering of additional units by the Company on February 25, 2015, the Series A Warrants are now exercisable at an exercise price of $2.20 per share. The Series A Warrants expire one year after issuance. The Series B Warrants were not issued in our IPO and will only be issued upon the exercise of the Series A Warrants, with each Series B Warrant being exercisable for one share of common stock. The Series B Warrants are immediately exercisable upon issuance at an initial exercise price of $8.75 per share and expire on the sixth anniversary of the date of issuance.
