Inquiry (采购产品): replacement parts I have a 24 position N-EVAP with the dual band spring at the top (11250). I have owned the unit for a number of years (more than 8) and the dual band spring has now started to misalign making it very difficult to smoothly raise or lower the sample holder (it tends to get stuck near the top). Is it possible to purchase a new dual band spring for the unit? I checked your on-line catalogue but couldn’t find the part listed. Thank you for your time. **** Hidden Message ***** Shelley Lang B3H 4J1 CAN Company: Dalhousie University E-mail: shelley.lang@dal.ca **** Hidden Message ***** shelley.lang@dal.ca
