About this file
This document outlines requirements for a temperature sample holder to be provided under a federal contract with the National Institute of Standards and Technology. The contractor must deliver one temperature sample holder capable of heating and cooling samples mounted between glass slides from 0 to 200 degrees Celsius, with temperature control of +/- 0.2 degrees and variations of 0.1 degrees or less under ideal conditions. The holder must accommodate slides measuring 15 by 15 millimeters to 25 by 75 millimeters and maintain a heated area of at least 22 by 22 millimeters. Software control of the holder must include an API for programming via Python with temperature readings recorded at 1 Hz. Additional requirements include adjustable sample viewing areas, specified working distances and angles for optics, heating and cooling rates from 0.01 to 50 degrees Celsius per minute and -0.01 to -30 degrees Celsius per minute, respectively, and the ability to use alternative sample atmospheres. The contractor must also deliver the associated software and operations manual within 30 days of award. Formal acceptance will occur once the government verifies all performance standards have been met.

STATEMENT OF REQUIREMENTS
I. SPECIFICATIONS
The contractor shall provide one (1) Temperature Sample Holder that meets or exceeds the following requirements:
Equipment Requirements
• The sample holder shall be capable of heating and cooling a sample mounted between two plain glass slides, for light transmission optical measurements (scattering and microscopy). The holder shall be able to hold user-supplied slides that are dimensioned at least 15mmx15mm and at most 25mmx75mm. The heated area shall be at least 22mmx22mm.
• These slides shall be held in place, so that the sample holder can be mounted vertically or in any orientation, while maintaining control of the sample temperature.
• The transmission aperture shall be between 2 mm and 3 mm in diameter.
• The portion of the sample covering the aperture shall be adjustable by translating the glass slides. The distance of travel shall be at least ±5 mm in each perpendicular direction.
• The working distance for lens optics shall be no more than 6.5 mm on one side.
The viewing angle on this side shall be at least ±45 degrees.
• The working distance for lens optics on the other side shall be no more than 13 mm, with a viewing angle on this side that shall be at least ±17 degrees.
• The temperature shall be controllable from 0 °C to 200 °C.
• When a step change in temperature, heating, (for example, from T1 = 20 °C to T2 = 30 °C) is commanded, the measured temperature will of course experience a finite transient during a time period that shall be no more than ((T2-T1) + 30) seconds before being stable at the target temperature ± 0.2 °C. For the example of a temperature change of 10 °C therefore, stability at the target temperature shall be achieved within 40 seconds. After this transient time, the temperature shall remain within ± 0.2 °C of the target temperature, and variations in temperature shall continue to decrease until achieving steady state variations. These steady state variations shall be ± 0.1 °C or less, under ideal lab conditions.
• When a step change in temperature, cooling, is commanded, the corresponding time before stability at the target temperature shall be no more than (2*(T1-T2) + 40) seconds.
• The integrated temperature probe of the heating unit is capable of directly sensing the sample volume without affecting its temperature.
• The heating of the sample shall be at a programmed rate which can be adjusted between 0.01 °C/minute and 50 °C/minute.
• The cooling of the sample shall be at a programmed rate which can be adjusted between -0.01 °C/minute and -30 °C/minute.
• The sample environment shall be enclosed and accessible with ports to the outside so that it shall be possible to use an atmosphere other than air, such as, for example, nitrogen, carbon dioxide mix, or moist air, inside the housing.
Software
• The sample holder functions shall be computer controlled, including with one (1) API so that NIST can program them all by python. Using this same API and software, the temperature readings for sample history record shall be at a frequency of at least 1 Hz.
Manual
• The Contractor shall provide one (1) electronic copy of the operations and maintenance manual for the Temperature Sample Holder. When the equipment is delivered to the end user.
Warranty
The Contractor shall provide, at a minimum, a one-year warranty for the laser. The warranty shall cover all parts, labor, and travel. The warranty shall commence upon successful Government acceptance. Repair work may be performed at the Contractor’s location.
II. DELIVERY
100 Bureau Dr.
Bldg 224/A205 Gaithersburg, MD 20899-8542
Delivery of the instrument shall be accomplished at NIST, Gaithersburg, Maryland. Normal duty hours are
Monday through Friday, 7:30 a.m. to 3:00 p.m. with the exception of Federal holidays
III. DELIVERABLES
Description Quantity Due Date Temperature Sample Holder One (1) 30 Calendar days after award of this requirement.
Software 30 Calendar days after award of this requirement.
Manual (electronic copy) One (1) 30 Calendar days after award of this requirement.
IV. ACCEPTANCE CRITERIA
Formal acceptance of the system will be given by the Government SME after the Contractor demonstrates that all performance standards in this statement of requirements have been met.
