The phrase "average product size" is correct and usable in written English.
It can be used when discussing the typical dimensions or measurements of a product within a specific category or market.
Example: "The average product size for smartphones has increased over the past few years, with many models now featuring larger screens."
Alternatives: "typical product dimensions" or "mean product size".
The calculations show that the average product crystal size for the recirculating crystallizer is significantly reduced compared to that of a well-stirred crystallizer if the circulation rate is not sufficiently high.
One hundred and nine miRNAs were amplified with 56 primers designed by PerlPrimer v.1.1.17 (37) (Supplementary Table III, available at Carcinogenesis Online) using long range PCR (TaKaRa LA Taq™; TaKaRa Bio); the average PCR product size was 4763bp.
The model was then used for performance evaluation of the reactor, in terms of removal efficiencies of struvite constituent species (Mg, NH4 and PO4), and the average product crystal sizes.
The older version comprises the NR-21, BAT-26, BAT-25, NR-24 and NR-22 mononucleotide repeats with average PCR product sizes in Caucasian individuals of 103, 120, 124, 132 and 142 bp, respectively (Suraweera et al, 2002).
The newer version of the assay comprises the NR-27, NR-21, NR-24, BAT-25 and BAT-26 repeats with average PCR product sizes in Caucasians of 87, 107, 126, 148 and 179 bp, respectively (Buhard et al, 2004, 2006).
The average expected PCR product size for these 24 loci was 240 bp.
The porous material used was the commercially available Merck purified sea sand with an average particle size of 100 300 µm (product no. 1.07711.5000).
Four of the markers (ASSR4, ASSR6, ASSR18, ASSR22) did not amplify any PCR product, one marker (ASSR21) showed a larger than expected product size, while nine markers amplified but did not show distinct polymorphism on agarose gel electrophoresis perhaps due to small product size difference (average 4.8 bp difference), or actual lack of polymorphism.
