Spectrophotometer (Absorbance) Cuvettes

Rectangular Open Top Cells, Macro Cuvettes

1-Q-10 quartz cuvettes Spectrecology
Open top rectangular absorbance cuvettes, 1 – 100mm pathlength. – Style 1 – Spectrecology

The most basic, fundamental cuvette style, fits virtually all spectrophotometers. Rectangular cells. Macro cells refer to the internal volume that holds the sample. These cells have an internal width of 10mm, a length equal to the optical path length (choose from 1 to 100mm) and a height of 45 mm.  The cells come with Teflon Lids. There are two clear windows (for transmission/absorbance measurements). The sides are frosted to help eliminate stray light.

Variations on this theme include stopper topped cells, and different internal widths — 4mm semi-micro, 2mm micro.  Materials include Spectrosil quartz (170 to 2200nm), Infrasil quartz (220 – 3800nm), Glass and special optical glass. Additional options include self masking black quartz to reduce stray light and screw cap cuvettes with septa or solid caps.

All cuvettes can be ordered by phone, by purchase order, or by credit card. Many of the styles can also be ordered from our secure online store Shop.Spectrecology.com    If you would like a formal quotation, please call us or send an email info@spectrecology.com
