1 SANYO Electric Co., Ltd. Biomedical Engineering Department Copyright Performance Testing of Haier Model

2 SANYO Electric Co., Ltd. Biomedical Engineering Department Copyright VWR Symphony Branded with List Price of $14,245 (115V) and $14,445(220V) (This is Haier's model # DW-86L628 VIP Series...) - Haier (not VWR) calls is VIP Series in the literature which may be violation of SANYO's Trade Mark VIP - 3 Year Warranty from VWR. (Personally I think they will regret this.) - V.I.P. construction, 22 cu.ft. only. - They do not state how many 2" boxes it holds however, in their picture they are showing just 320, but I believe it will probably hold up to 400. Anyway, it holds 20 racks.. (Remember our MDF-U7386SC holds 480, with 24 racks) - New VWR Private Label

3 SANYO Electric Co., Ltd. Biomedical Engineering Department Copyright - Danfoss compressors ( no size indication or of origin probably manufactured in China.) - They mention American Temprite oil separator and German made EBM condensation fan ( no mention of Chinese made anything) - 4 inner door(4 compartments) - which appear to be gasketed ( probably insulated but they don't mention this). - One handed door opening ( which they say is patented, which we have already had in the MDF- U7386SC) and we will have to check this our with our patents.(We had it first so they can't patent) - It states that the interior is stainless (but doesn't appear that way from the pictures - looks white and painted). Actually stainless steel is a worse conductor than regular steel. New VWR Private Label
